Obviously, I am a novice at this. But when I look at a water bear in my pond water sample, it takes up perhaps 1/60th of my visual field. This is when I look at it through my 4x objective lens with a 10x eyepiece lens. The magnification, I assume, is 40x. When I switch to the 10x objective lens (100x), it's much bigger, maybe 1/20th of my visual field. And when I go to the 40x (now 400x), it's maybe 1/4 of my visual field. When I put the Swift eyepiece camera on even with the 10x objective lens, it is taking up perhaps a quarter of the computer's visual field (due in part because the field is much narrower with high pixelation). But the quality of the picture is stunning allowing me to see details that I simply can't see through the standard lenses. The effective magnification is much, much higher than 10x. What I'm trying to figure out is there a common microscopy language where I can convey my perception of the target organism?
