Yep, by 5.6 they are gone. Sharpness rly impressed me, on the short end a bit blurry, but on 35mm just wonderful.
The only thing buggin me, is the minimun focus distance of 0.5m. |
Yeah that would bother me a bit too. I don't know about other photographers, but I find that the widest setting on a lens that offers a wide-angle range is the one I use most. For example, with my old Vivitar S1 24-48 f/3.8, I find that I use that lens at 24mm most of the time -- simply because that is the most useful and desirable focal length in the entire range.
So when I read that a lens is a bit soft at 21mm I'm really concerned about that. I wouldn't be so worried about the 35mm end, but to me the 21mm end must perform the best. Is this just me or what?
Does the softness on the short end improve when the lens is stopped down to say f/8 or f/11? |
I wouldn't say it's soft... it's just soft in compare to the long end wide open  When shot glasses, focused on the inscription, on the sort end the letter's are a bit soft, but maybe it's because of APS-C sensor with 21mp, on FF it would look equally sharp I guess. |
