>>4243537>>No, it correlates with sensor size>no, it correlates, to photosite area and price.Here are different photosite and price tiers, yet they all show roughly the same FF performance.
>>4243541>what situation do you need iso 25600 (or 6400 on m43) for?Low light street, low light reception without flash, indoor sports with a slower lens.
> ive shot street in poorly lit areas and gotten away just fine with iso 3200 with a slow kit lensThen it wasn't as poorly lit as you claim.
>having to push two stops higher on iso with a ff body just completely negates the advantage of ff in low light as well, since 2 stops is the theoretical max improvement a ff sensor can give, obviously this will never be the case in the real world.It's always the case in the real world. For the same sensor tech and exposure FF always gives 2ev better noise performance.
