Here's my latest acquisition: an early 80's Carl Zeiss Jena 135mm F3.5 MC lense with M42 thread. Cost about £50 off eBay plus £20 for the M42 to Sony-E adapter. Only had it a day, but so far the quality of the photos it produces looks stunning. A bit of lateral CA, but that can be corrected really easily in GIMP. Some very boring, but sharp photos are here: CZJ135 Photos
