Danny, your images are beautiful and compelling and are pushing me to purchase a Sonnar!
However, I do have some questions regarding your technique, specifically:
1) Is your lens optimized for F2.8 or F1.5?
2) What apertures do you typically use?
3) Do you compensate for focus shift?
Thanks for the lovely images!
Scuse the stupid question, but does focus shift matter when you are shooting digital, I mean can't you see where it is focused in the viewfinder or screen?
