Did this a few years ago (more like 6) ... thought I'd try it again. Many of us are using old M42 mount lens now. It's easy enough to do with all the adapters catering to the ever growing mirrorless camera users.
So ... show us what you've done with your M42's (or other manual focus lens).
Here's a couple of recent entries (will take new photos for this side event moving forward). :-)
- Sears 55/1.4 on Sony A7II
- Sears 135/2.8 on Sony A7II
- Ricoh Rikenon 55/1.4 on Sony A7II
Not the most artistic photo, but I felt like I wanted to post something. :-) Took this tonight after doing some yard work ... it was dark and thought I'd experiment with some bokeh results. Didn't quite pan out the way I thought it would.
