Hi,
The Canon 55-250mm STM lens has 0.29x magnification which is better than any native current zoom lens for MFT. The effective magnification on MFT is therefore 0.58x which is very good for butterflies and other bugs where a larger closeup working distance is needed. This exceeds the magnification from the PL100-400mm, PL50-200mm, OL300mm and OL 12-200mm lenses at a very good cost ($300).
I'm therefore considering buying one and pairing with the Viltrox EF-M1 adapter to mount on my OLY E-M5 Mk iii and PAN G9 cameras.
If anyone has tried this combination, would appreciate your feedback on how well it works on OLY bodies supporting PDAF and PAN bodies supporting DFD.
Thanks in advance.
