>>4156980do not overthink this:
the sensor is smaller. SNR is a function of this. smaller sensors have more noise. the subjective effect is similar to raising the ISO.
it is a 150mm f2.8 lens. it has the DOF of a 150mm f2.8 lens. the FOV is cropped to 300mm equivalent because the sensor is smaller.
there is no image magic here, but the lens can just be designed with a fuckton of vignetting and come out a hair smaller for it since the vignetting isn't over the sensor area.
for shopping comparison purposes every micro four thirds camera is up two stops on ISO at all times and everything is doubled with the DOF halved but that's not what's *really* going on.
it's just a smaller sensor with all the things that implies.
>>4156985the subjective effect of crop sensor SNR is increased ISO, meaning larger sensors take cleaner pictures. it's a fact of life.
it's just a smaller sensor with all the things that implies.
