A80 dark corners

Hello,

When I had an A75 I never had dark corners in the pictures. With my new A80
I can see many pics with dark corners.... What's going on? Is it defective?

 

The Canon A series digital cameras have a high degree of sample
variation...each individual unit is very unique. Some have a tendency to
get firmware errors for no apparent reason, other have vignetting/blurry
corners, where some (probably the majority) work as they should.

 

A lot of the point and shoot cameras will vignette (dark corners) when
shot very wide with a large aperture. Go through the pictures and
compare the focal length with the aperture and see if you can narrow it
down to that. If so, no problem - it's just what lenses (especially
lower cost ones) do.

 

I guess Im gonna have to exchange it with another A80.

 

Yes you should exchange it, possibly test at the store. I have tested over
7 higher end P&S cameras
(and several cheap ones) in the past 2 years and none had the problem of
dark blurry corners at wide angle.
Sounds like a quality control issue. Don't accept it or look at another
brand if it is a recurirng problem.

 

Sounds like an issue with someone not understanding the optics.

Some lenses will show some vignetting when used wide angle with the
maximum aperture. This commonly occurs at the corners and can be
distracting, but is easily fixed by stopping the aperture down one or
two steps. It is not a defect, but a matter of design.

However, without any test shots it's impossible to diagnose it one way
or another.
