I'm considering the Nokton 25mm, but am wondering about how difficult it is to focus it, given that it's completely manual. I understand that the lens must have the focal length entered in the settings, but is everything manual? ie set aperture, iso, shutter speed manually? Can you set viewfinder to magnify when focusing?
I've looked at lots of pictures taken with the lens, but wonder how many were taken that were not in focus. Is this a lens you'd use only for static scenes where you have time to work through process of getting it set up. Lots of questions, but it's an expensive lens, and not a purchase I'd make without a lot of consideration.
