Best lens for macro electronic components

Mechanically, you need a step-down ring to 43mm filter thread, that should be doable. Don't use the included universal adapter even if it fits, it's weak plastic junk prone to breaking and dropping the Raynox on whatever you are photographing.

Yes exactly!! Why we mentioned earlier "If cost is a concern look to the Raynox DCR-125 and 250 add on Lenses, these are very usefully and work well, and should do a decent job with your Canon 20-70mm. We used these often and they also work well as a "tube" lens working with infinity type microscope lenses for getting down to detailed chip images. BTW be sure to get the necessary "ring" adapters for the lenses you would like to use with the Raynox."

I hope this is not too far OT. Way back in the 70's, I had a real Nikon F. Then got a macro lens for it (can't give the exact one) and used it for documentation and comparing immunoprecipitin bands. Used B&W negatives. It was fantastic. In fact, since it was my personal camera and lens, I rarely took that lens off even when that particular project was done.
I am not into $>5K equipment (2022 equivalent) anymore, but find the Z50 attractive. It comes in a kit with a 16-50mm lens. Any opinions on that lens' macro abilities. The cheapest Z-macro seems to be the MC50/f2.8 at $650.
Edit: Spell check didn't like "immunoprecipitin." That's what they are.

You don't have to spend a lot of $ to get some decent macro images, the final rendering is 90% behind the camera and 10% equipment ;)
The 1st image is with the $18 mentioned AmScope 4X lens, think the 2nd image was with a clone 5X that cost $250.

I failed to mention that as a retired pathologist I have several microscopes. I made an adapter for my CoolPix 990 to my binocular/dissecting Nikon microscope. It works too. I want something simpler, uses modern memory, takes less space, and has more uses. 60 years of junk accumulated over a career takes up a lot of space. I am trying to cut back to save my hiers the pain.

You need to get "ring" adapters which will mount the Raynox to the front of your lens. As mentioned by magic, don't rely on the plastic spring loaded grabber supplied, get a proper set of ring adapters, they aren't expensive.
