At 18mm it looks like F/5.6 and F/8 have least blur units.
At 35mm F/8 - F/11
At 55mm F/11
Thank you

For most lenses it's 2-3 stops down from
wide open.

Technically, the aperture should be around F/8 or F/11. Any higher than that, and your images will start "suffering" from diffraction.

However, this doesn't really apply in practice. I shoot concerts, and if I shot at F/8 all my shots would fail due to motion blur. Then there's the landscape situation, where you might need to stop down to F/16 to get everything in focus.

I wouldn't worry too much about it, honestly. Nobody looks at shots at 100% except pixelpeepers.

that is what i have been told by a lot as well. some lenses it might be a wider. on my 28-135 i can get sharp photos at f/6 sometimes

i have a 50 1.8 do say that anything higher than 2.8 and its not going to come out very sharp. i usually shoot on that in the range of f/5 and get some really nice photos. that is for outdoors stuff, in low light your going to want to open up unless you camera does great at high iso

dont believe everything you read on google though some of that stuff can be wrong or misleading

pretty decent article for a pretty good magazine http://www.dpmag.com/how-to/tip-of-t...-09-20-10.html

I wouldn't get overwrought about which aperture is the sharpest. Use the aperture that suits whatever you're shooting.

I have been told that a good rule of thumb to start with is that stepping down 2 stops from the widest setting will often produce the sharpest image.
