Re: Viltrox Speedbooster - Compatibility with my Lenses

I've just tested EF 100 macro 2.8 L on M50. Focus with and without speed booster is slower than on 5dmIii, but accurate. IS works correctly.

Without speed booster the af hunts a bit in low light, but improves noticeably with the speed booster

I'd forgotten how good this lens is even at f2.8. Been a while since I've used it
