when snapping subject-matter at this sort of distance I should shoot either wide-open (or thereabouts) or else stop down fo f5.6 and beyond

Thank you pippy! That’s exactly what I’m going to accommodate to in the future. I used to get exactly what I wanted at F4 from a front-focus M-Rokkor 40…where the back focus originated from physics compensates the front focus. So for a long period of time I relied on F4 for low light guess-focusing and the results were superb. Now I just need to train myself again.

Revisiting this thread.  I've had my LLL Speed Panchro ii for a while and always used it for relatively close up shooting.  The other day I was out and noticed it wouldn't focus to infinity on the SL3, it was far short of it.  So now I need to send it out for adjustment.  Does anyone know someone reputable that can do it?

Better check  the M/L adapter first !
