I normally shoot a 5DII, but when I want a change of pace and that film look, I'll go to my old Pentax MX and SMC-M lenses (28/2.8, 50/1.4, 135/3.5). I've been very happy with it, but then my uncle planted this seed in my head that has me wondering. He said that back in that era, Nikon was considered the gold standard, then Canon, Minolta, Olympus, then Pentax. I'm 36, so I wouldn't know. Is this true? I get great results from my Pentax film gear: How much better could a Nikon be? I'm thinking of getting a Nikon FM2 to find out. I can't imagine the 50/1.4 could be any better at all, but I think I use my 28mm more than the 50, so that is a major consideration. The Pentax 28/2.8 has a 5-blade diaphragm, so I think it's a mid-grade lens. Seems sharp though. Does the Nikon 28/2.8 blow it away? Thoughts?
