Subject: Medium format copy lens
Date: 2015-10-21 13:12:29
From: John Thurston
I'm not terribly knowledgeable about lens design and
selection, but I know there are differences. If, for
example, I were looking for a copy lens I expect that
flatness of field would be an important characteristic. I
also expect it would need to be able to focus at the
appropriate distance for the media being copied.

Let's pretend I wanted a medium format copy setup with about
a .2 magnification. What lens and camera might do the job at
a moderate cost?

You need the Makro-Planar® T* 5.6/135 CF and the bellows extension.


I have this kit for sale. Not yet on ebay.

Can you explain to us why this is what I need?

And why a 1:1 macro lens is your recommendation when I'm
pretty sure 1:3 or even 1:4 would do what I might want done?

Personally, I would be looking for a high quality enarging lens that I could mount on the intended camera using bellows...

This is, essentially, what the Bowens Illumitrans was - but that also incorporated adjustable back lighting for the slides that it was used to copy...

Of course, with DSLR cameras, a simple light box can be used instead.

This lens has no distortion. Like other photographers, I used it for MF slide duplication.

I also have the adapter to mount it on Nikon bodies.

But you're right. I've read your message too fast. I assumed you need a lens for 1:1 dupes...
