>>4016409>Size & weightFor a given lens focal length and aperture equivalence, full frame is lighter and smaller for 99% of lenses.
>Stars don't moveYes they do, an mft pic of the milky way will have 2 stops worse noise than FF, and FF still struggles even with an f1.4 lens.
>20mp is enough resolutionModern camera resolution is 95%+ limited by the lens, not the mp count, and a lens on a sensor 1\4 the size needs 4x the resolving power to compare.
>DofFF is more versatile, being able to get much more shallow dof, but still able to stop down. A single human eye is about a 35mm f2 equivalent, there is no 17mm f1 mft lens. Your eye has lots of bokeh, it's just impossible to focus on, be more conscious of your peripheral vision.
>>4016410>I like grainThat's heavy cope. And if you really do, you can add it in post to a clean image. And no, older systems weren't grainy, any photographer that did more than holiday snaps would buy into medium format film systems, with a iso 100-400 film these are arguably just as clean as any full frame digital shot.
No, reality doesn't have grain or noise.
>Editing isn't photographyYes it is, always has been, always will be.
You're coping because you're a talentless hack that doesn't have the patience to actually learn anything. You took up photography as you thought it was little more than clicking a button, and you're mad it actually takes practice and talent that you don't have.
