Re: Goniometer Recommendation

The question in this thread is about a two-axis goniometer. Alan, the item you referenced doesn't appear to include any goniometer at all. I don't think it is on topic for this thread. --Chris S. That is my impression too, the link seems to show an XY shift stage (a.k.a. translation stage, plus a r...

Re: Best Lens/Accessory Option to Achieve 1.5-2:1 Magnification with Micro Four Thirds?

In the interesting discussion that's been going on, I'm wondering how to fit a 1.4x doubler on the Olympus 60mm macro because the M4/3 teleconverters have the rear lens housed in a long tube that prevents these teleconverters from being placed on lenses that aren't They are specifically made for th...

Re: Best Lens/Accessory Option to Achieve 1.5-2:1 Magnification with Micro Four Thirds?

[...] Which brings me to the next question - does the AF in-camera-stacking on micro 4/3 cameras only work with Olympus and Panasonic lenses or is it possible with older adapted lenses like the Sigma 150mm in EF or 4/3 mount? That would be an interesting way to get more working distance than any 60...

Re: Cow Patty Critters

Hi, all. An entomologist I know released a book "Cow Patty Critters - An introduction to the ecology, biology and identification of insects in cattle dung on Canadian pastures" this morning. Whew, that was a mouthful. I only perused it lightly and it looks very informative. I suspect it also applie...

Re: Lisprice of Nikon Eclipse E400 Pol /Value of used instrument

The link takes me to an online shop, not to a PDF.

PS - never mind for me, it was easy to find another copy on the web.

fs: Zeiss Tessovar photomacroscope

There are at least two different things known as Zeiss Tessovar. One is a system for photomacrography. This is what I am offering. The other Tessovar is an adapter for photomicrography equipped with an eyepiece port for focusing. There might be also other things that Zeiss called Tessovar. P4093803s...

Re: 1mm WD

Has anyone actually tried to use the Olympus LMPlanFL 50x BD 0.50 or UMPlanFL 50x BD 0.80 on an Olympus BD illuminator? Or any other Olympus objectives of the same two series on an Olympus BD illuminator? How did it work on a three-dimensional subject? I have the LMPlanFL 50x BD 0.50 (the one with 1...

Re: 2x Mitutoyo objective. Any good?

[...]While I've not had one in hand, the Laowa 25mm f/2.8 2.5-5X Ultra Macro is said to be very good in the 2.5x-3.5x range. (This is not a bellows-mounted lens, but goes directly on the camera.)[...] I have a couple of tests of the Laowa 25 mm available at https://savazzi.net/photography/laowa-25-...

** discounted ** fs: various finite microscope objectives

A small batch of finite objectives. P4043751s.JPG Lomo Apo water immersion 70x 1,23 with correction collar for cover thickness 10-20 (0.10-0.20 mm I guess). The collar turns and stops at either end of the range, but there is some dead play when you reverse the direction of rotation between the two e...

[SOLD]** discounted ** fs: various finite Zeiss microscope objectives

Now going through my boxes of microscope parts. I have 7 Zeiss finite microscope objectives I have not used in years and cannot test. They were all fine last I checked, but things may happen with time. I figured out I could offer the whole batch at a price low enough that it can still be interesting...

Re: 2x Mitutoyo objective. Any good?

I agree with essentially everything Chris S. says. I have Mitutoyo M Plan Apos 2x, 5x, 10x and 20x on a Mitutoyo FS-60 microscope with automated stacking, and it is good to have them filling up all four mounts in the turret. The 2x is certainly the most limited of these four in IQ, probably because ...

Continuing through my boxes of legacy lenses, some of the lenses below are legacy lenses for photomacrography that have been discussed on PM.net at one time or another. Others are large- to very-large-format lenses that might be of interest for use in a specialized darkroom, or on large-format camer...

** Sold ** : Oshiro 60 mm f/2.8 2x macro lens

The Oshiro is one of the first macro lenses focusing between infinity and 2x. It came out immediately after the Laowa 60 mm f/2.8 lens and was even advertised with pictures of the Laowa lens, but it is, and looks, slightly different, optically as well as mechanically. I reviewed and tested this spec...
