This is similar to another thread about sharpness, but what I'm looking for is a lens that is sharp wide open. I have the 50/1.4 and 50/1.8 Mk1 and while they sharpen up nicely at about f4 or 5.6, they leave much to be desired wide open.
Here's what I'm looking for:
Wide aperture (prefer 1.4, but 1.8 would work. Maybe f2.)
Sharp wide open.
Approximately normal length. Something from about 30mm-85mm, 30 would be better than 85.
Autofocus (so Zeiss and Samyang are out)
Any suggestions? I'm seriously considering the Sigma 35/1.4, but I'm seeing conflicting reports of exactly how much better it is than others, and how it compares to other focal lengths. Can I get sharper with a different length?
I currently shoot on a crop body, but may move to FF on one body. I do not need weather sealing. IS would be nice, but not essential. Sharpness is more important than price, but price will be a factor.
