This is the original image...

And this is the crop. Note the CA, especially on the trees.

Thanks for your opinion. I suspect this camera is going back to Canon.

I wasn't really trying for a strict 100% crop, so I can't answer the question. This is a 100% crop:

That actually looks a lot sharper than my G10 at 100%. I'd be happy with that but perhaps my expectations are a bit different.

You can eliminate some of the CA if you shoot in RAW. Were you shooting in auto or did you have manual settings ?

# Exposure Time (1 / Shutter Speed) = 1/800 second = 0.00125 second
# Lens F-Number/F-Stop = 4/1 = F4
# ISO Speed Ratings = 80
Exposure Mode = auto exposure (0)

I probably would have shot AV mode and set @ f/8 in this bright light. That might help with the CA. I don't shoot auto and expect great results with this camera (or any), you really have to play around with it to get the best results.

f/8 on this camera would give rather soft images due to diffraction effects...

As to the original image, that looks pretty odd! I've only seen noticeable fringing on strongly backlit shots, although I've not used the camera all that much yet.

Actually, I'm not sure why it shot at that speed. I'm sure it was the camera's decision (P mode, probably).

Maybe I'll go back and try it with a smaller aperture and see what happens.

And ISO=80? What's with that? :lol:

I would say yes, that looks great for a G10

That does perk it up. I really didn't do much post processing in these images beyond cropping. Mainly I was just worried about the CA near the edges.

I definitely want to try a similar shot again, but do it right this time. Then I'll decide whether I need to worry about the camera or not.

I think you're doing pretty well with it. It's as good as my G10.

Here's the before and after with a little bit of punch-up in PP.

I think my real problem is expectations. I'm used to shooting full-frame DSLRs, and this is probably an unfair test for a compact.

Overall, the image is pretty good until you start pixel-peeping in the corners. I guess I had expected (hoped) for better. I can certainly live with it, however.

The G10 is a great camera, but it still has a compact sensor. You can't pixel peep the images if you want to be happy. Just view them at your intended output sizes, not 100% and you'll be happier.
