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...
