I am trying to pick out a lens to build a microscope camera, boom arm-mount. I do solder work on PCB’s, mostly DIP. I use a 5x large lens mounted on a boom arm now for years, but want to step up to a video feed system, take snapshots, etc…

Confused with the lens selection. I need range, like 12" ideally so I can fit my hands in there, a solder sucker, 3rd-hands, etc… Manual zoom/focus ok now for my first starter solution. What I can not find is a demo comparison to help me choose the right lens. I think the ones that I can fit the barlow on the bottom would be right for me, from what I saw so far they allow me to move the camera up without 2-3" of space between my work. But I do not know which of the 100x, 130x or 200x len’s to start with. Looks like the cheap 100x ones the people need two-hands to adjust the zoom on a cheap plastic housing, which might have plastic lens inside, which I do not want. Then, I do not know if 200x is too strong. I think I only need about 10x - 20x magnification with a good field of view, without creating a bubble-distortion, having everything square and tidy. So I have been trying to pick out a lens, which looks like they have the small levers stick out, which shows me they could be moved by fingers, without needing two-hand force to spin the zoom and focus.

So if anyone has advice, something to add to my research so far I would appreciate. I am waiting for the module to be delivered, so I will be buying a lens within the next few days. I prefer not to waste my money on mistake without knowing that I am getting into. Like a surprise booby-trap; where one not align/work with the HQ imx477 sensor size on this module.
