>>4188432With M43 you have the same effect of cropping out 3/4 of the full frame sensor. This makes the noise look 4x worse, but they usually have more megapixels per mm so the details look passable enough. But now, bear with me, that probably doesn't affect you.
In real, normal photography use, shrinking the image down from the camera's 20mp will eliminate a ton of the noise. The more you shrink it, the more noise goes away. Printing at 300dpi will also minimize the amount of visible noise. Web images are typically less than 2 megapixels. 8 max, for wallpaper sizes. Most people do not want prints larger than 8x10, which only requires 8 megapixels for a 300dpi print.
Shooting with the same settings as every full frame user, your final images (not the unprocessed 100% size raws, viewed at 100%) will only be very slightly graineir and softer. M43 is like 35mm film, while full frame digital is closer to 4x5 film these days.
Just, please, do not "crop for reach". I've read cope blogs, always by birders, about how "full frame is yesterdays format, fool frame users are kidding themselves, you only need micro four thirds, REACH!", showing off the cropped after being passed through a pipeline of AI denoise, enlargement and sharpening programs... and then the final photograph looks just plain bad. They do this because using a longer lens to get the same effect leads to the image distorting just from the air, and they don't want to get closer. Do not enlarge micro four thirds output. Even enlarging full frame output gets sketchy. If you want a bigger photo take one to begin with. Get closer.
