Why does my 24-105 have a different magnification (macro ratio) from a 105mm macro lens at same MFD?

Re: Why does my 24-105 have a different magnification (macro ratio)

I now have both in hand. The panasonic exhibits basically no focus breathing, including at macro ranges, but the sigma exhibits extreme breathing at the macro range. I'm not sure exactly what specifically in your tool would show this, but I do think that breathing does seem to play quite a large part, but I am not sure whether as a symptom or a cause.

As a side note, this lens is quite exceptional. I've scanned some film and the detail is quite great, and the corners are just as flawless as the center even wide open, not something I've seen in other macro lenses I've used. I'll need to do some specific testing to see how it performs in 96MP pixel shift high res mode, but from quick tests it appears to still have very high pixel level detail at that resolution. Very impressed.
