Took a new Zero 612F out for some shots yesterday and today and had loads of fun. Was quite a conversation starter too! Will get the color shots back next week and have to figure out what developer I want to use with the Efke R25. Rodinal isn't available in town unfortunately. Can't wait to see if my metering and reciprocity compensation was OK!
Disclaimer: I made a bodycap pinhole a few years ago... And after my couple initial shots, it was apparent that it was more useful marking dust spots on the digital sensor than it was in making anything photo worthy!
