trying to fix in would be all most impossible, (this camera is a very old model) , she was use to all the funtions
that's whay I replaced it with one like she had.



I recommend this to everyone for their excellent design

What's good about the A-720is:
1. Very good value at it's price point. I paid $190 for mine. For this price you get an 8 megapixel sensor, 6x zoom lens, optical image stabilization, full manual controls, 2.5" LCD screen (115,000 pixels), and an optical viewfinder. This last is handy for when your batteries are getting low - you can turn off the LCD and still take pictures with the viewfinder.
2. Excellent image quality. Images are sharp, exposure is generally pretty accurate, and color saturation very nice. Of course this isn't a digital SLR, so don't expect miracles, but for a camera small enough to stick in a shirt pocket, the photos are remarkably good.
3. Optical Image Stabilization. Most cameras have this now, so it's not really remarkable.
4. Uses "AA" batteries instead of a lithium pack. This is actually the defining feature of the Canon "A" series - they all are "AA" battery powered. I prefer this as you can get "AA"'s anywhere. Unfortunately, the A-700 series began the current Canon trend of downsizing from four batteries (in the A-600 cameras), to only two. This has caused a noticeable increase in flash recharge time, plus of course the A-720is itself needs battery changes more often than it would if it used four batteries. However, I don't mean to imply that the A-720is is "slow". It's power-up speed, shutter-lag time, and time to first shot are all pretty good, and are at least equal to the average for other cameras of this class and price point.
5. Very simple, yet powerful, control layout and menus. This camera has only a few buttons on it, and the menu is as simple and user friendly as it could be. This camera would not intimidate an older person unfamiliar with modern electronic gadgets. Even with it's paucity of buttons, it still manages to have full manual controls. A really nice feature is the ability to program the direct print button to another function, most useful is probably to change ISO speed.
6. 640 x 480 x 30 frames-per-second video. This is pretty much standard on cameras in this class, so not really a special feature. Like all compact still cameras, the quality of the sound captured during video shooting is horrible - if you want good sound, get a real video camera - but the video image quality is pretty good. Video is stored in the standard MJPEG format.
7. Uses standard, cheap, easy to find SD and SDHC memory cards. You can put an 8 gig SDHC card in this camera for about $20 and it will capture 2888 stills at max image size and best quality, or about 70 minutes of video clips.
What's bad about the A-720is: There's not much to dislike here. There are a few features that it doesn't have:
1. No flash mounting shoe, although this is such a small camera that sticking a flash gun on top of it would make it so top-heavy it would be hard to control.
2. No RAW capture capability. Th


You see Canon has largely crippled the latest in the A series (after the 720 and 590) by removing control, manual and otherwise, from the line. Gone is Aperature and Shutter Priority let alone full manual adjustment. The newer S/SX series is taking over this space. But one of the most important things I realized from having used this controllable A-series for these years is how important a compact body AND a viewfinder is. On my recent vacation I was out in direct sun alot. You cannot see LCDs of any digicam in full sun. Having some kind of viewfinder is not an antiquated hack like a film advance lever, it is necessary. The SX110 (evident immediate successor to the A-series control) has no viewfinder. And the SX1 is has not lived up to the previous S models and has the weight and bulk from 4 AA batteries. So the A720, unless replaced by another controllable 'A' appears to be the end of the line for this great series.
Looping the A720 back into this discussion there is something that bothers me about it besides the flash recycle time. And that is aspects of the design. The small grip is pretty good. Canon is having problems getting the 'grip' right on their low end digicams (Digital Rebels and SX1 being examples of inadquate grips) but the A720 grip is ok for A720 size. The newer A series is blending the grip away which is a mistake. But having an A720 for a year and a half the thing that is really starting to bug me in general about Canon is the lack of innovation most evident in the menu system. The menu system on Canon camera at the low end is virtually identical and it lacks panache. It looks like something you would give to children. When you look at the menu system of Nikons you have something slightly better and the Panasonic menu systems like in the FX37 is much easier to navigate than Canon.
So when I boil down why I am still using the A720is it is a combination of size and image quality. Going smaller in any camera line I know of will not get you the image quality the A720is has to offer. All cameras are compromises and the A720 hit a very usable sweet spot in design that I do not see Canon aiming at again.
The overall impression I have is that Canon has lost their edge. They still have the best overall image sensor quality, but the packaging in the camera body, and the menu system, have been very much hit and miss. Nikon have edged them out of the low-end DSLR space, taken bites out of their higher end DSLRs, and Panasonic have bitten into their P&S end. Pentax having surprised with K10d and K20d, and micro 4:3 also looking like a potential player. I don't see Canon doing anything revolutionary to get an edge and their groove back. The SD1200is and siblings are cute minicams but they do not feel like a solid camera like FX37. The A720 has few if any worthy siblings in the current low-end Canon line up.
Oh, and for my bridge camera search, I really wanted to like the Fuji s1000fd/s1500fd. The size and outer ergonomics of that style are spot on. But image quality is not good overall. The Nikon P90 is too big and image quality flat. The SX1 is too big. In general I am most impressed with Panasonic as a camera line. The FZ28 is a very nice camera but with the FZ models having an annual sales life I've decided to wait for the FZ38 or whatever the FZ28 successor is.





Summary: It is very easy to use and delivers great quality photos in a variety of situations with an absolute minimum of skill and zero talent.
***
Update: It's now April 2010, and with my two babies, living on the coast and going to the beach, and moving twice, it still works a charm.
About me: I bought this camera to take pictures of my daughter and my family. I am a very poor photographer with a good appreciation of photography, which is a painful situation to be in. In the past I have used a 3 mega-pixel camera phone, a Kodak camera in about the same price range, and then some Sony digital mini-cameras. I use this camera mainly indoors in medium light (energy-saving bulbs, late afternoon, overcast or raining). My approach is to take pictures early and often and hope for the best. I was looking for a camera that had great potential and that even I (read: one of the worst picture-takers you'll ever meet) could get some decent pictures with. I have never taken a photography course and never will, because if I have the time and money I will spend it on something I can hope to actually get good at. I think I am a pretty typical camera-buyer.
About the camera: This camera met all of my expectations. It is very easy to use and delivers great quality photos in a variety of situations with an absolute minimum of skill and zero talent, which is what I wanted from a point-and-shoot.
When the other reviewers say it doesn't work well in low-light, they mean, very low light, like this is not a camera for amateurs that want to do some good photography at night or in a room with only a 20-watt bulb. The flash works fine for the rest of us! I certainly have not had any light issues and we do not live in the brightest of houses or climates. I used the night mode for quiet times and the auto-with-flash for active night pictures and they turned out fine.
This camera is nice because it has two functions that help poor photographers in particular (in addition to other modes that probably help everyone equally): the kids and pets function, which allows you to take picture after picture in quick succession so you don't miss any action, and the auto function which provides a higher-quality picture. If I use these according to the recommendations in the user's manual, I can usually get 25 - 50% of my pictures of a moderate to good quality, as compared to an (imaginary) amateur photographer who actually knows what she is doing. That is compared to 1 - 5% of pictures using a camera phone or another cheap camera without these easy-to-use modes.
This camera is not so small that I lose it in my purse, which is a danger with tiny cameras, if your purse is anything like mine.
The stabilizer is also great since I take pictures while running after my toddler. I had considered buying the very cute Nikon in the same price range (the one that looks like a Brownie camera), but they did not have stabilizers, so I finally went for this one and I am very glad. The function works great.
One thing that they don't mention in the descriptions is that you do not have to switch between the viewfinder and the LCD display, like on some cameras. What I mean is that you can look through the little window like on regular cameras, OR at the big screen, like on digital cameras, all the time, without switching view mode. So you can switch from person to person without having to switch the view mode. This is great because my mother likes the viewfinder and I like the LCD. I also like to switch between them.
Another nice thing that I like is the ease with which you can switch from taking pictures to review mode to look at the pictures you took. It is a separate switch that you could find in the dark if you needed to. That is nice because I have deleted many a batch of photos trying to figure out how to get into the mode where I can review the pictures I have just taken.
The pictures I have taken with this camera are located at [...] (this is an ad-free, non-commercial set of our family pictures). You can see which ones were taken with the Canon A720IS by clicking on the photo and looking in the right-hand column, and compare them with other pictures I have taken. As I have mentioned I have no skills or talent in this area so if you are someone who really wants decent pictures but are also a photo dunce who just wants a picture of your kid or grandkid, this would give you a good idea of what to expect.
(If you are an amateur or pro photographer, this review and those samples are not for you because you could probably do better with a camera obscura.)
I would certainly buy this camera again.

This particular camera has uses AA batteries and there is a little trap door on the bottom of the camera that opens up to reveal the batteries & the memory card. So, this little door gets a lot of use if you use the camera on a regular basis--either when changing the batteries or when removing the memory card to get the pics off. Unfortunately, the entire functionality of this door relies on a tiny piece of plastic on the body of the camera that the door latches to. Obviously you and I and Canon all know that anything made of plastic is going to break--probably sooner rather than later. And, the way this tiny little flap of plastic is integrated into the body of the camera--it's virtually irreplaceable. So, on that tiny little 2 cent piece of plastic, Canon hung the entire functionality of this device. That was either very stupid or very calculated. I tend to think the latter.
So, all of a sudden one day the door won't latch back tightly enough to hold the batteries in place--which means no power to the camera. I mean, you can kind of take pics if you use a couple of fingers to squeeze the battery door shut--but it's clumsy and if you release the pressure even for a moment the power supply is interrupted and the camera dies.
In electronics life cycles, 14 or 16 or 18 months may seem like a long time--but I have 35mm cameras that cost a fraction of what this camera cost me--that are 15, 20, 25 yrs old--and still work fine. In fact, they take better images than just about any point & shoot digital. And they have little trap doors for the film and/or the batteries as well... but somehow they seemed to be willing to make those devices more durable--possibly because the technology didn't really change much over the years. (film, light, shutter--image... so simple a caveman could work it)
Not being one to reward poor design and cheap manufacturing, I will not buy another Canon. I have already bought a replacement camera--a Panasonic Lumix DMC-LZ8 with Leica optics & a wider angle lense. To be honest, the image quality doesn't seem to be quite as good as the Canon--particularly in low light (which is why I bought that particular Canon model). But it cost $110 instead of $200 so if it craps out in 14, 16, 18 month--I guess I just buy a new one.
In the past I've had to replace several digital cameras--usually for electronics malfunctioning--which, for some reason, I can accept more readily than just cheap, pettiness on the part of the manufacturer. I'm all for smaller & lighter but not at the expense of basic quality & intelligent, considerate design & manufacturing. One by one every corporation seems to be changing their paradigm to view the end users not as "customers" but as "cash flow potential". Thus, there is no brand loyalty anymore--because there are no quality brands anymore.


I have read the other low ratings, so I know what I am in for with this poor rating, but I will not be deterred. When I buy a product, I always look at the lowest rated ones to see the potential problems. Granted, people should not give a low rating for shipping issues, or the time it takes the company to send it, but they should if they would have made a different purchase decision if they had had the information previously. I give a 1 to something I would never purchase again, and would tell anyone considering it to STOP!! and DON'T DO IT!!
So, with that in mind, here goes:
It eats batteries. All types of batteries. Every battery. I've tried everything. If you plan on taking your camera on vacation take several boxes of batteries... NIMH whatever... it burns through them faster than any camera I have ever owned. Absolutely infuriating.
It is soooooooooooooo slooooooooooooowwwwwww to take a picture. To get a picture of the child blowing out the candles of a birthday cake you need to take the picture while they are INHALING!!! Piñata picture? Press the button during the kid's windup (I've actually gotten some pretty cool pictures using this method with candy flying all over).
So, you might think those aren't good enough reasons to give a camera a poor review, you may question my competence, and demand I take a camera class prior to ever reviewing a camera again (or better yet, save everyone's time and destroy my keyboard) but what people don't understand is that with kids, you've got to move fast. You can't be saying "wait, I need more batteries" when they are racing for the tree X-mas morning. It doesn't matter how great the picture quality of the birthday photo is if the picture does not capture the surprised look on their face, but instead captures the wrapping paper being tossed away.
So, with that in mind, and with the overwhelming majority suggesting that I am completely out of my mind, go ahead and decide on your own. Who knows, maybe I just got a lemon...

However when the two SD cards arrived, they were SDHC cards which aren't compatible with our cameras. The SD cards which we received says SanDisk SDHC Card 2GB. I can't even use the SDHC cards. The image displayed on the Amazon page should match the actual product - and this product does not. So warning to everyone else, this product is actually an SDHC card.

Size & Looks:
Not as small as the ultra-compacts, but it's very hard to find one smaller with all the manual controls that Canon A series P&S cameras offer. Having aperture and shutter priority modes and a wide enough ISO range (80-1600) is a must for more creative shooting. If all you shoot is in auto mode (& occasional scene mode), then there are other cameras that are sleeker & smaller (such as the SD series). I personally prefer a darker color, silver on an obviously plastic body is a pet peeve of mine in all electronics these days. Just a matter of personal taste. I wished the camera was slightly lighter & smaller. The main weight should just be a high quality glass lens, everything else can be electronics & plastic. A lot of pros like the Canon G series because of the solid metal frames. But that's mainly because in the dSLR world, everything weighs a lot more. In a portable camera I want portability. Unlike shrinking cellphones & MP3 players these days, the big lens (& preferably bigger sensor size) should be the limiting factor for cameras. I want lenses big enough to let in enough light at the largest zoom and also not suffer from barrel distortion & other abnormalities. Another reason why I didn't go with ultra-compacts that have prizm-folding optics.
8 Megapixels:
This is on the low end for currently introduced new cameras. But it's more than I (or most people) need. 8MP is enough for all but poster-sized enlargements. Higher megapixels have problems such as denser sensors that have more noise and less dynamic range, and requiring more memory/disk space for storage. More camera buyers should be informed that high megapixels does not mean better image quality, and actually introduces new problems.
Zoom:
This camera has 6x Optical zoom. I was tempted to get the new SX100 with 10x optical zoom. But I would have to sacrifice the A720's optical viewfinder and slightly smaller size. Also from an earlier Kodak Z712 (12x optical zoom) I owned and sold, the higher zoom was not as appealing as it seemed at first due to a number of reasons such as hand shake (even with IS), slightly less optical sharpness at all zoom levels, and the added bulk. 6x optical zoom is good enough for 90% of the shooting I do without sacrificing size and image quality. A wider wideangle would also be more beneficial than a longer reach (28mm at the wide end instead of 36mm).
Optical Image Stabilization:
A very important feature in cameras these days, especially with a small lens that could always use more light. I can take hand-held pictures about 2-3 stops slower than without, which means the shutter speed can go as low as 1/10 sec in wide angle without blurring the pictures (while keeping ISO low for less noise). IS is even more important when zoomed in at 6x in all but the sunniest outdoor conditiions, again this is limited by the small optical lens. The more zoomed in, the smaller the aperture, and less light hitting the sensor, so the camera needs a slower shutter speed to expose the picture properly (which means steady hands or tripod), this is compounded by the higher sensitivity to hand shake when zoomed in.
Optical Viewfinder:
Optical viewfinders are rare among cameras in this class from other brands. Kudos to Canon for including it. The benefits of a viewfinder include being able frame & shoot in sunny conditions that would wash out the LCD display. Also once I have the settings set, I can just turn off the LCD & shoot through the viewfinder for framing to conserve battery power (up to 4x as many pictures taken per set of batteries, 900+ on NiMH) The viewfinder is about 80% of the full image frame, so there's enough buffer for framing error so you can crop digitally later on a computer. The viewfinder is slightly offset from the sensor so it's less reliable for close shooting and definitely not recommended for macro shooting. The A720 IS doesn't have a swivel LCD display, but I prefer it since it only adds cost & bulk to a camera. LCDs today have enough wide angle viewing so they're still usable if I want to shoot from way above or below eye level.
AA Batteries:
This was a very important factor in my decision when shopping for a digital camera.

--------
[the long version]
I was so excited to get this camera with image stabilization and face recognition, because old camera would occasionally take blurry action shots, and I didn't like the recharge speed. Unfortunately, this camera simply doesn't cut it on either point, despite the rave reviews I've seen on every site and in Consumer Reports. I'm told this is because I commit the cardinal sin of using the flash regularly plus an occasional zoom.
This camera is actually worse than my 6-year-old Canon subcompact for speed. After pressing the shutter down, I wait a full second or more... enough so that I'm tempted to press the shutter and THEN say "one, two, three." And then I have to wait at least 6-8 seconds (unfortunately I'm not exaggerating; persists even with different batteries, different memory cards, and different quality settings) before I can take another shot--long enough for the cute moments to be long-since finished, so there's no way I can get a second shot of the same cute moment :(
The inability to take a "second chance" picture is an even bigger problem because about one out of 3 pictures is crazy-blurry... enough so that you can't recognize my daughter even though she's just 5-8 feet away and the only person in the picture (e.g,. taking a picture of her Halloween costume, indoors with good light coming through the window). Even a close-up of my daughter and infant son together shows her beaming at him, and his eyes streaking across a four-inch span. Granted, he -did- move, but he's only 4 months, and that's sort of expected! Apparently this is because nearly all the various mode options (including "kids and pets"--there is no "sports" mode) have a slow shutter speed. (And yes, you can configure a faster shutter speed, but only if you're willing to take full manual control, which I don't have the time to do while playing with kids.) For those pictures with no movement that were insanely blurry, I wonder if the IS was kicking in when it didn't need to (possibly combined with the bugaboo of slow shutter speed). Who knows--either way, my other cameras take great, non-blurry shots, and this one doesn't. In fairness, the the camera -did- tell me to use a tripod... but that icon never turned off, period. And as a mom of a 3-year old and a 4-month old, it's ludicrous to think I'd be carting a tripod around with me just to take pictures of my kids! Incidentally, when I tested the same model in a store, the same thing happened--the icon never turned off.
Another quirk I noticed while trying to get good pictures is that the facial recognition is, well, silly. In one picture of my daughter, it zoomed in on her neck rather than her face. In another picture of my son in a bouncy seat (which is a solid off-white), it focused over one shoulder, so as I pressed the shutter down halfway to get it to pick a new focus, it selected a spot over the other shoulder, then on his belly, and then cycled through the same choices again. Another shot of my daughter focused on the tile behind her (pale gray with white grout), and another selected the (solid, off-white) wall rather than her face. Ummm... and my children are quite photogenic with typical features, so it's not a case of them being Picasso-esque so as to confuse the camera! (Incidentally, I've since noticed other reviews of Canon cameras saying things like "about half the pictures I took at Thanksgiving were blurry," which I had previously discounted.) I partly wonder if it's a software issue, since the camera would fade into and out of focus, until settling on unfocused... but then presumably other people would have noticed the same problem as well, so who knows...
Despite all of the above, convinced that the problem was me, I tried several things:
* different memory cards (including high-speed ones)
* different megapixel settings
* different ISO settings
* different mode settings (everything except "fireworks" and "snow scene"! ... as mentioned, there is no "sports" mode, and "kids and pets" astoundingly has a slow shutter speed... as do most of the other modes)
* different batteries (including lithium a



It's way too large for my sons SX100IS, and my A720IS would take about a week to find inside it!
If it fits your camera, it is a well made case, though.

* The auto-focus is very poor, and due to the small screen size, many times I could not tell a shot was out of focus until I viewed it on my computer at home.
* Flash recharge takes FOREVER.
* Battery level indicator will tell you that the batteries are low only a few shots before it shuts-down.
* DO NOT USE A POWER CORD WITH THIS CAMERA! I used a power cord, and the camera decided that all batteries from that point forward were not good enough. Brand-new alkaline batteries with 1.8V on each were deemed insufficient by the camera, which insisted "change the batteries." No matter what batteries I put in, I got that error. I became tied to the power cord.
