>>3832934>>3832923Oh god, it's the morons applying crop factor to fucking everything.
An f/1.2 lens on MFT is an f/1.2 lens.
All of you retards don't even understand that f number is a fraction, calculated based on focal length and the circle diameter.
Because MFT needs a smaller image circle, a smaller aperture diameter will have a higher f number.
So, an f/1.2 MFT lens will be about as bright as an f/1.2 lens on a 35mm system.
You don't see these morons applying crop factor to everything on medium format...
Take the fastest medium format lens... some 6x4 Mamiya f/1.8 lens. That's got a crop factor of like... 0.62. That Mamiya isn't suddenly some f/1.1 lens though, because crop factor doesn't fucking work like that.
Lens brightness is always relative to the system, and should only be compared with other lenses within that system. Of course, the alternative would be to compare T-stop, but that's a whole other discussion.
