I can understand because one cameras focus ring turns more revolutions you could assume it is more "precise". I'll agree technically it is certainly true, but in practicality for most (the exception might be a lot of very close up work where you are probably doing focus stacks anyway) the Alpa with the new rings is very precise - more than adequate. Personally it would drive me nuts to turn the lens that much to get it focus. As a landscape shooter, knowing that infinity is nailed is more important so I prefer shimming over an offset. But I think either system offers amazing stuff, and the real issue facing most tech camera shooters as the pixels get smaller is the lens design and resulting issues with wide angle lens. At this point, unless there is something wrong with my back, my Schneider 35XL is not usable on my Alpa with IQ180 back - even LCC doesn't compensate for the falloff and color shift. I'm better off shooting my DF with the PhaseOne 28.
Do the Arca lenses all turn past infinity in case the sensor plane requires that, or are the adaptors designed so that most of the time infinity needs to be fine tuned a little inside the infinity mark? Just sort of curious how that works.
I assume the offset is very consistent, so you only have to remember "one" number? How difficult is it to actually apply that, something easily done in the head or do you always have to refer to some guide or calculator? I feel like I'm in molasses when working with these cameras anyway, curious if this is a "no brainer" or if it slows you down a little more. (Please don't get defensive on this one, just asking because I admit working with any tech camera is a different world than SLR)
