Hi, I started out with my fathers Retina IIc in 1972. Two years later I've saved to buy my first camera, an SLR. Used SLRs since then. I shoot b&w, make my own prints and love it. Now I'm curious to try a rangefinder again, have decided for a Zeiss Ikon Zm (seems to be a great camera, I use glasses, acceptable price, etc etc). I want a 50 mm to start with. I'll get the ZI with the Sonnar ZM 1,5 for a really good price, 200+ euros cheaper than with the ZM Planar 2,0. I've read the zillion threads written on the internet since 2007 about the focus shift in the Sonnar lens. I know the Planar is a great lens. I'm not obsessed about resolution or sharpness, I'd love the artistic look the Sonnar is supposed to give. And I certainly appreciate the (almost) extra stop. BUT I wan't to know exactly where focus in the picture is, without having to lean back or forth. Otherwise I choose the Planar instead. It's between these two lenses, the Planar or the Sonnar. Can't make up my mind. I know that other people have started similar threads earlier, elsewhere, but PLEASE help to decide!
