Hi guys, I'm pondering buying some extra alt glass to play around with on the A7r (and maybe the E-M1, though if I'm honest there's enough great native stuff for that and I don't love the focal multiplier effect). I've got a couple of Zeiss (C/Y 35/2.8 and 50/1.4) which I'm curious to compare to the natives (planar and distagon vs. Sonnar), favorites on my 5D, a pair of Leica R lenses (50/2 and 28/2.8). Missing is some more wide angle, and maybe a short telephoto. I have a Yashica non ML 135/2.8 as well but that never really did anything for me. Love the focal length, meh on the glass. I've got a lead on a few options, was wondering what experiences folks had: - a non MC Zuiko 21/3.5 for well below average ebay pricing (275). Can add an 85/2.0 for 250 ir a 100/2.8 for 150. Upside: tiny glass, and I should be able to shift it at minimal loss if I don't like it. - contax Zeiss distagon 18/4.0. Reviews are decent enough, but it's not one of the most loved Zeiss lenses. Found a copy for around 500 in god condition. - Leica R angulon R 21/4.0. More expensive than the above, doesn't get crazy good reviews. I'm hoping Zeiss do a native distagon 21/2.8, preferably native AF, but that'll be a while yet. Anyone with thoughts or experiences on the above?
