Yeah, it just has 23mm sockets. I am going to try transplanting an UW binocular onto it at some point, since the bolts holes are the same, but for now I just use 10x/22 eyepieces which are pretty good.

The infinity optiphot head I have isn't technically ultra wide, but I think it has the same tube lens as the ultrawide one since it's physically wide (same width as an ultra wide one), seems to have the same elements as an ultra wide and does very well on direct projection on aps c. I could 3d print...

I recently got an Olympus BX40 which I have been getting fixed up. I got a good deal on a SWTR-2 superwide head which was missing the top dovetail for mounting camera hardware (it also had some issues with the prism slider until I opened it up and removed the plastic bag of bolts that was inside it)...

I had almost forgotten this objective but I'm trying to clear out some of my backlog and came across it again. It's a Nikon E plan 50x/0.75 epi which came free with a nosepiece I bought. I figured I should try it with the BD Plan as a comparison. I need to take photos anyway to make sure they're in ...

Neat! You can always add a quarter wave plate after the second linear polarizer if you don't want plane polarization.

I'm not sure what they cost new, but the BD plan was 35 bucks shipped (hence my inability to resist it). Microscope Central is asking just over 1k for the LMPlan 50x https://microscopecentral.com/products/unitron-examet-5-lwd-metallugical-objectives?variant=1067207733 (though that one isn't marked a...

Hi everyone. This week I got my hands on three 50x objectives which I needed to test out, so I thought I might as well run them head to head to head to see how they'd do. https://i.imgur.com/1tAYHb6.png They are: A solid black generic BD Plan 50x which I got cheap on eBay, a Mitutoyo M50 objective (...

Parfocality and alignment are spot on on my two good copies. The visual impression is good even with the generic plan objective--the blue ghosting at high mags aside you still get good detail and planarity, and across a wide field of view. The image does dim a bit as you zoom in which is not ideal b...

I posted this over on microbehunters, but I figure it might be of interest here too, though stereo microscopes are rarely going to be anyone's recommended tool for photography. I've been wanting to do this comparison for a while, but I kept getting distracted. But I have finally run a comparison of ...

Wow yeah, I would have bet money that was an ammonite at first glance. It even has the suture pattern!

Looks great to me! It had better at 16k, but in optics that certainly doesn't always follow. I'm glad you're getting to put it through its paces, and really curious how these other tests will turn out (though I think I can guess at the gist).

Oh yeah, I forgot to actually paste the link. That's the one.

These are impressive photos for such a wiggly little critter!

That's fair, though accidental matches are partial at best since there are multiple aspects to the correction. So it's still not a great idea to judge these objectives based on their performance with unrelated, partially compatible hardware. (Related fantastic link here with the only objective measu...

No offense but it's kind of silly to use a compensating objective without compensating optics--definitely not optimal. Giving neo splans a bad rap because of CA with direct projection is a bit like complaining an infinity objective has low contrast without a tube lens.
