p.1 #1 · Is the Sigma 30mm f/1.4 usable on full frame?


People say it was mainly built for aps-c sensors since it balances out to 50mm but is it clear of vignetting or anything else on full frame (5d)?


btw I love this lens on my 40d

It vignettes pretty heavily on FF. Someone posted samples from using it on a film camera not long ago, although I don't remember their username

It doesn't just vig - the circle of light is physically smaller than a FF sensor, so the image simply drops. You could crop, but you'll lose about 30% of the pic.

Pity. My assistant's copy is sharp enough wide open it would take a good copy of the 35L to compete with it.

Don't think I didn't try when I got my 5D!

from memory the image circle is actually large enough to cover aps-h but not ff, but at wide apertures theres quite a bit of vignetting which improves when stopped down.

ok google search brings up ken rockwell

'The Sigma 30mm f/1.4 is not a wide-angle and it doesn't work on film, FX or full-frame cameras. I tried it, and the corners go black on full-frame'

True, I tried it. I did not realize my 30mm wouldn't work until I mounted it up on my 5D and took some shots. It was my favorite lens on my 40D. I was sorry to see it go.
