Thanks for taking your time to reply, and sharing on the focus bit, something new i learnt! May i ask what the workflow is like when you scan? So you would use af every shot and check it manually? or just use manual focus? No idea how to make sure each one is in focus across so many frames!
Hmm I dont think i would upgrade it anytime soon? Given that I dont shoot digital much, thats why price is a large factor.
Ive heard only good things about the sony 90mm, but it really is so much more expensive as compared to the sigma 70mm.
Thanks for your input though, definitely leaning on a native sony lens now!
