Do you have one?

What aperture do you think gives you your sharpest pictures?

I don't think there is any right or wrong answer to this question. Does it vary by camera or lens?

I've read that it's usually about 2 or 3 stops down from a lens's widest aperture, but I don't know for sure.

Steve, I haven't actually tested any of my lenses for their sweet spot.

But, on APS-C, a photo taken at an aperture smaller than f/8 will suffer from diffraction.
