Was I under a rock or is this a brand new item? Yes lots has to do w/ resolution, etc. but.....

This gets kind of interesting for me. I have been pondering what I should do w/ my enthusiasm for digital imaging aka photography.

There is no getting around a low light opportunity (and size as in still large) for a M5 adapted w/ a 24 or 50 1.0 lens sticking on it. There might be marginal gain in a 40 2.8 or nifty fifty on an M5w/ adapter.

Heck on a tripod the light concentrating ability (smaller image circle) of the 150-600 gets kind of interesting.

Kind of like a 70-200 f 2.0 for some of those early morning shots of ospreys fetching b-fast.

Thoughts.
