Thanks for the examples, appreciated. Best, John

I did a very quick search from ebay uk but I did not find any Olympus PlanApo short mount available. Or did I get my search string wrong? (Olympus PlanApo (add ?x and 0.?) microscope objective).

BR, John

Oddly enough, I am moving to the Olympus short-barrel PlanApos. I lucked upon a Vanox AH with DIC for a great price, and started to collect short-barrel PlanApos mostly because I was interested to see if the DIC would work better with objectives from the same era than with my Nikon CFs. Plus they p...

Is either of them coming from or travelling through an a present extreme weather region?

But there are also some generic Chinese 10x/22 eyepieces that perform really well with Nikon CF objectives.

It is definitely possible to use Nikon condensers on Olympus microscopes; I used a Nikon dark-ground condenser on my BH-2 until I found a cheap Olympus one. It may not be possible to use Olympus condensers on Nikon microscopes, I...

Yes, Lou it was a QV 10x 0.28. And thank you for the observation against the Apo 20x 0.42.

Hi ADi

QV 10x, definitely not HR ( I cannot find the link now, might have sold!!)

Hi Lou I have been looking around and talking about getting a 20x for APS-C on a Canon M6M2 using a camera tube lens at infinity 200mm. Whilst browsing a bit I came across a 10x QV which was engraved with f=100 with the thought that I could push it up to 20X on 200mm. I hope that my musing is still ...

Hi All

Apart from the Mitutoyo QV Series does any know of any others designed for a 100 mm tube lens?

Thanks, Best, John

> I can't recall right now what this lens type is called in the videosurveillance circles. A surveillance or TV camera pinhole lens. Looking in my shed, I have a Lenzar Optics 9mm f3.5 pinhole lens, bought many decades ago. Virtually no info available, but Cosmicar also made them. Ebay item # 32400...
