Quick question - does anybody have both of these lenses? I am trying to understand how two lenses with the same focal length and same MFD can have a different maximum magnification numbers... this is my question in the other thread for background:
https://www.fredmiranda.com/forum/topic/1335976

With that said, I was wondering if anybody has both of these that could confirm that when they are both @ 70mm, they frame a subject virtually the same and both have the same MFD. I am quite sure I want the version II but I am very interested in using it at its MFD for food photography so the apparent change from 0.29x in version I to 0.21x in version II seems substantial, but yet I cannot in any logical way quantify how this is possible.

Any help is much appreciated.

Mark

Believe it.

See your other thread for the explanation.

It has to do with optics and math- both things are better stated by someone with a better understanding of those principles.

The lenses framing at any focal length will be comparitively different because the lenses are at different physical lengths at their comparable focal lengths. That is, they are physically at different lengths from their subject.

As for quality- the ii beats the every loving snot out of the predecessor.

The II is better than I. I had two of the first version.
