let's say you have a 2.8 lens wide open and it is soft.. doesn't sharpen until F4. you have another lens that is F4 but sharp wide open.
what is the use in paying the extra money, extra weight, etc? bokeh better sure but if it's not unusable wide open what is the point?
All opinions welcomed!
People using the 16-85 and 60-250 have asked themselves that very question, and come up with the most satisfying answer possible
I tend to agree, I'd rather have a smaller lens that's a bit slower but sharp at all apertures, instead of a fast lens that's useless wide open. I have primes when I want super wide apertures. On the other hand, sometimes there's no solution other than using a fast lens...
