Reasons For DSLR: Sharpness
2007-08-26
Another reason for going DSLR is sharpness. Although I could get sharp images with the S3, such as this teddy bear (click for original):
Teddy bear: 1/160s f/4.5 16.8mm, Canon S3 IS, unadjusted
I could not get them all the time and not across the whole image. And I had to exchange sharpness for something else all the time because of the inconsistency.
This one is taken with the Canon 30D. It uses the camera's saturation set to +2 but is otherwise unmodified and unsharpened:
Embassy Suites: 1/1000s f/8 ISO 400 -0.3ev, Canon 30D, EF-S 17-55 f2.8 IS, unadjusted
It's very sharp, at least to my eyes. And testing this lens I find it sharp all the way to f2.8. The 70-200 f2.8L IS lens I have is even sharper, and sharpest at f2.8. I reckoned that my chances of getting a bad lens from Canon were small. Reports I see say that these are consistently good lenses, and my experience bears that out.
