>>3861498>because a 50mm lens is still a 50mm lens even if you crop it, so you'll get 50mm f/whatever subject separation from it and a 100mm lens at the same f number will get more subject separation, exactly double as much. DoF is directly proportional to length and inversely proportional to aperture, so if you halve the length you have to double the f number to get the same DoF.Nobody's talking about DoF dumbfuck.
DoF≠low light performance.
>picrelated, 20x24" is best low light system, here's a 33mm f/0.65 equivalent lensThis is your brain on bokehwhoring digipleb sensorlet.
