Well, problem is I did try one in the shop and was blown away by it's IQ under the shop lights @1.4. It's bit bulky for my liking, and I just hate the hood, it's way too big IMO.
Would I miss my other lenses? Well, K50 depends on how good the DA* would perform, K55 most probably not, and M85.... the 55 would be my longest lens and for streets I like using 85 so I guess yes I would miss that one too....
My dream line up:
10-20 + FA*24 + 31ltd + 43ltd + DA*55 + 77ltd (or FA*85)
it's good to dream, isn't it?
