The lense produces soft images, with sharpness really dropping off at the edges. Grain is visible in the sky and darker areas even at the 80 ISO setting. Macro performance is bad.
What I find truly appalling is the speed of the lense in terms of 'light-gathering ability'. The lense is rated at F3.4 widest aperture, but even in pretty bright conditions, the shutter speeds are slow, and this results in blur when taking pictures of animals and action scenes etc. How can this be ?
Well, I compared the results from an older Powershot A610 (2006)set to the same focal length, aperture and ISO setting. I found that for the same scene, the old Powershot chose a shutter speed twice as fast ! Obviously a faster shutter produces sharper pictures. Canon are not being entirely honest with their claim of F3.4. Now the SX150 has image stabilisation which helps of course, but this is no substitute for a fast lense ! If there is any movement in the scene, it will be blurred. One way around this is to select a higher ISO, but this increases the grain.
Another problem is the focus performance - the old Powershot will focus reliably on a wide range of objects - a jet flying high in the sky, or an object 1cm away. The SX will not lock onto an aircraft, and it often gives the green symbol in macro mode, only to find on review that it's out of focus ! There is only one focus option - centre, whereas the old powershot has a moveable focus point so that you can compose a scene with the main object of interest off-set to one side.
Rather than chasing a higher pixel count, Canon should have concentrated on better optical and focus performance - and all those manual options simply can't come to the rescue...







So, as I was saying, I've dragged this camera to heck (Missouri, specifically) and back. Well, beyond back; it's been as far west as the Oregon Pacific coast. I usually keep it in the pocket of my motorcycle jacket, where it enjoys whatever weather protection the textile jacket affords. It worked perfectly for years, and then (probably because of bugs and road grime stuck in the lens cover) the lens stopped opening or closing completely. I'd turn it on, take a shot, and then discover that the lens cover hadn't completely opened, leaving black triangles on the upper right and lower left corners of the shot. But a bit of cleaninig made the problem go away.
The modes:
I've never understood what the difference is between auto mode and easy mode. Both of them are complete "point: shoot" modes. The night snapshot mode is good for exactly what you'd expect. And the macro mode is very useful. I never did manage to get any decent results from the manual focus mode. I do like that it's easy to turn off the flash (an option that many more point and shoot operators should take advantage of; if your subject is more than a couple of feet away, you're better off without the flash - spectators in stadiums, take note). Something else I like about this camera is that the shutter lag is unusually short; it's not quite DSLR-instantaneous, but it's darn fast. One last point of praise; the inclusion of an optical viewfinder is great. It has real advantages over using the LCD screen to set up the shot, especially in bright sunlight.
Now the "but." This is an older camera. For what this costs, you can set yourself up with a decent used DSLR or a much newer point and shoot, with features like sweep panorama, smile detection (not just face detection), and so on for much less money. Note that I'm not saying you can get cameras with more megapixels. You can, but there are much more important criteria than megapixels. Unless you print bigger than 11x17 on a regular basis, and you need to crop down and then print that big, you don't need tons of megapixels. 8 megapixels is plenty; heck, if you never print bigger than 8x10, 4 megapixels will do just fine.
