Dec 18, 2010 15:36 | #1 I took some test shots with my T1i/500d and my 17-55 lens. I want to make sure that I'm getting the highest IQ possible and that my pics are as sharp as possible. Would you be satisfied with these results? Are these "normal" results? (Not all of the series came out this sharp. This was one of the best.)

Dec 18, 2010 15:47 | #3 Yes, that's where I wanted the focus in this test. I just wanted to know if the image quality & sharpness is what you all would be happy with? 7D Mark ii, T1i/500D, 17-55 2.8, 100-400L mk II - More Gear

If you wanted total sharpness a aperture of f 16-20 would give overall sharpness. But isn't the focus point on the one behind the one highlighted the loupe?

Dec 18, 2010 16:06 | #6 Yes it DOES seem to be front focusing based on this example. Should I post another example? 7D Mark ii, T1i/500D, 17-55 2.8, 100-400L mk II - More Gear

JeffreyG "my bits and pieces are all hard"  More info | Dec 18, 2010 16:55 | #7 Unless you bought the 17-55 to mostly shoot near the MFD, I do not think that testing near the MFD is a great way to assess focus performance in general. My personal stuff:http://www.flickr.com/photos/jngirbach/sets/

The 17-55 is not a macro lens, so you must have been pretty close to the MFD to frame a flower that tight. My personal stuff:http://www.flickr.com/photos/jngirbach/sets/
