I think aperture should be driven more by DOF than by sharpness. I mean, my 24L might be sharpest at f/2.8, but if I need f/1.8 than what does it matter? Just a thought...

+1.....Most of the time when I'm indoors with my 30mm/85mm primes, I NEED f/1.4-1.8. I'd take a non-subject-blurred shot at the expense of some sharpness (where I go W-I-D-E aperture to get my shutter speeds up in low-light/no flash)

From my limited experience:

50mm f/1.8 II - sharpest at f/8
28-105mm II USM - sharpest at f/11
28-135mm IS USM - sharpest at f/8
35-135mm USM - sharpest at f/8

most of these are either going to be f/5.6 or f/8.

This is all subjective, but my three lenses seem to be sharpest at:

10-22 EFS (f/8-9)
17-85 EFS (f/11)
70-300 EF (not DO) (f/11)

The "sharpest" aperture probably varies with the zoom focal length setting.

Speak softly and carry a big zoom.

I will bet that the overwhelming rersponse will be between f8-11....

Unless someone has gone off and done a comparison at different apertures under controlled conditions all you’re going to get is subjective data. Not that subjective data is not valid, but it can vary from person to person and subject to subject. I sure would like to see the data though.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

Usually about 2 stops down from maximum aperture will give the best edge to edge sharpness...

Sharpness is a perception.
