p.1 #1 · Quantaray 50mm - Varifocal ?


I have a quantaray 50mm f2.8 macro 1:1 which I picked up used. Upon testing subjects, I realised that this lens changes magnification as focus changes. Does this mean this is a varifocal lens. If that is the case, how to do focus stacking without messing the magnification.
The below shot was taken without tripod.

Use a focus rail.

Magnification is supposed to change as focus changes
