>>4249277>Magnified images of gills/sporesGills? 1:1 and 1:2 are both fine. Spores? You need 1:1 (1x magnification, life size on sensor) macro to see most of these on a 20-30mp body, which is again, its own discipline. Even on MFT a flash setup is absolutely mandatory because DOF is razor thin even at f8, and the subject gets really dark. Both systems will be adding more light so FF will always be ahead in quality. Just heavier. For scientific/educational investigation of spore detail, you're encroaching on microscopy and would want a 2x or 4x macro on the highest resolution body you can swing for.

>Swapping the battery out dailyIf you're doing time lapses as stills or want to cut different video sequences together, because it will kill the camera when you do.
Basically you're going to have to lose some of the size/weight autism and go for panasonic or a larger olympus. Panasonic has a touch more resolution on the GH6 which helps a lot with scientific work. A Z5, Z6/II, or Z7/II would even be better and a pound or two heavier.
However, it still has a problem: Zooms. Zooms are needed for harsh weather, because you can't swap lenses in harsh weather. The 24-70 f4 s from nikon is extensively sealed and at its fastest aperture can shoot an entire landscape at 24mm without issues. So M43 starts out as a 3 lens, 2 rig kit and FF starts out as a 2 lens 2 rig kit
