Testing out another eBay purchase: a Unitron M LWD 20x NA 0.30 240/0 lens. It has a 17mm Working Distance at 20x, and has an effective aperture of f/33. Too much diffraction for my D7000, but I knew this before I bought it. At 15.5:1 mag, my effective aperture is f/25.8, which is marginal for small aperture diffraction. This image is 72 frames at .004 mm steps, via Zerene PMax.

Thanks, oldtigger. I'm hoping it might do even better at 14:1 mag. It's always a gamble trying the unknown, but for $30.00 I thought I'd give it a try.lookin good

Thanks, Douglass. Funny you should say that. I just said something similar on pfrancke's thread. I'm hoping to get some mounted specimens from my brother this coming weekend. The few specimens I do have are pretty worn.Now to find subjects worthy of your lens and your effort.

Thanks Muddy. Very sharp!! How did you mount the lens?
I mounted this microscope objective on a bellows with an adapter I got on eBay.
Thanks pfrancke & LoneRangeFinder.

I used one of those (62-37mm plus a smaller one) to mount my 8x objective to the front of my 105mm micro/macro lens. From what I am understanding, you have the lens mounted on the bellows with no other lens.
I have the bellows, but while I can reverse the lens holder end of the bellows assembly, I can't reattach the bellows to it without a lens reversed & attached, as the release button is in the way. Were you able to find an adapter that has the bayonet mount on one end and filter threads on the other? I was considering cutting out a hole in body cap.

That is what I did with a body cap to use my objective on extension tubes. A word to the wise: I'd be careful about mounting any objective using a body cap directly on a DSLR. The reason is that the objective may protrude too far into the camera body & interfere with the function of the body.I used one of those (62-37mm plus a smaller one) t... (show quote)
I also looked into doing this with an enlarger lens thinking they are flat field in design and would have better edge-to-edge sharpness. Well guess what that 75 mm tap will run you? Try $900-$1100. I gave up on that idea.

I think this is what I need to mount the objective to the bellows: RMS Adapter Microscope Objective to NIKON AI
