I'm trying to find the best 50 prime, and I'm interested in the Zeiss 1.4 but there is a noticeable dearth of reviews and the reviews that are out there seem to hint at overpriced and overrated ... yet the example pictures posted are usually stunning (of course, this means nothing) ... what, if anything, would make this lens any better or worse than any Canon/Nikon/Sigma 50mm? I'm really into the look of these old school lenses (the voigtlander's also look amazing) but there seems to be a mystique that shrouds these lenses ... what am I missing? Some are old and cheap but really hard to find, some are super expensive but poorly reviewed (if at all) ... I'm looking for the best, most magical 50mm for under $700 ... should I be looking for these brands or am I wasting my time?
