First, this forum is great!! I am gathering materials to set up a DSLR scanning set up to give to my Father for Christmas (and I’ll help him) to scan old family negatives and slides. I have already ordered the Essential Film Holder. But I’d like advice for getting a macro lense.
He has a Canon T3i (18 mp, APS-C I believe) and I have a Sony A7C (24 mp/ full frame).
Would the Sony be MUCH better than the Canon for scanning? If there isn’t going to be a huge difference, I’d rather set up the Canon. But if I need to spend more than $300 for the lense, I’d rather invest in the Sony.
What should I look for in a macro lens for the Canon?
Focal Length: It seems like a longer focal length is preferred, but what range is suggested?" 50? 100?
Auto Focus: Does it need to have auto focus, or is a manual focus lens fine? I saw some talking about controlling focus via tethering…which I’m guessing wouldn’t work with a manual lens (he he).
Used glass: Is there a reason I shouldn’t buy a used macro lens from B&H or someone?
Thank you for your time and help!
