Why: I am on a lookout for a compact wide lens to use with a full-frame L-mount digital camera. Size and weight matter to me.
I saw a nice lightweight old prime for Leica screw thread mount, and I reckon even with a converter it should be smaller than current equivalents built for L-mount.
I don’t mind using old manual lenses with corresponding implications, but would really rather not lose much more sharpness and quality to the adapter.
Some options I found:
Get an adapter straight from screw to L-mount. — Seems hard to find, so far I spotted only one adapter1, it’s fairly cheap but the absence of competition is worrying and reviews seem pretty bad (most of the old ratings apparently are for another item, listing switcharoo typical for Amazon).
Get two separate adapters from respectable makers instead: one from screw to M, another from M to L. — I’d expect double conversion to be bulky, but some adapters from screw to M seem compact enough2. Not sure how solid such a contraption would feel…
