Several months ago I picked up a used copy of the 17-40 f4L, my first ultra wide lens. It is fine but corner sharpness is bad, which I somewhat expected. I will likely replace with a 16-35L.
I cannot afford the new version 3 of the 16-35 f2.8 (as stellar as it reportedly is). I will have to choose between a used version 2 of the f2.8 or a new f4 IS (both sell for around a thousand bucks).
I know from reviews the f4 is better optically in the corners and I will likely go that way, though I would love f2.8. I am wondering if anyone has experience using both the version 2 of 16-35 f2.8 and the 17-40 f4 that I have now. Are they the same optically (especially in corners) or is the version 2 f2.8 better?
