....these are true ORTHOS, with FOV 43", and do not sacrifie optical performances like 10x/23, 10x/25 versions.
The E-PL Version is the "Extra Flat Field" Version, and they are best you can have on market, and they are super rare!
They have same performances as ZAO I 25mm!

Well, in short, I have tested my RKE28mm vs Zeisses Aspherics 25mm, and I prefer RKEs over Zeisses, and floating effect is so unique.....one negative thing on Zeisses: coatings on lenses can be easily removed when cleaning eyepieces often, which is big minus for Zeiss, when RKEs coating is MUCH MUCH better, which means, you can push hard when cleaning, and coating still stays, and on Zeisses completly removes!

Wow, I am really surprised the coatings are so poor since these are used in labs around the world and carry a premium price.
Could it be you received a pair with defective coatings, a bad batch, or bad application? I would place a call to Zeiss.
Good Luck,
Jeffrey G.

They arrived new, but I have read twice before about poor coating on Zeisses microscope eyepieces, and now I know about what it was word. But anyway, they provide superb views, but still for me not better than RKE 28mm, without doubt!

I wonder if any other Zeiss micro eyepiece owners out there can report if the coatings are "easily removed", or if they're just fine?

I must admit, I raised an eyebrow or three, when reading this. The coatings on my Zeiss eyepieces have always been the very best and repeated, gentle, cleanings have left them completely unaffected.

BTW, one should never, EVER, push hard when cleaning lenses. Not because the coatings may rub off, but because a small, hard dust grain may be pushed hard enough to scratch the glass. Dust isn't just pollen, tiny bits of human skin or hair, but can also be tiny grains of quartz, one of the hardest materials known to man. Common sand is largely made of quarz. Think about that. A friend of mine absolutely ruined a 40mm Zeiss huygenian by "cleaning" the eye lens of it with his hankerchief, which had picked up a grain of sand somewhere. It wasn't pretty.

A speck of dust or a few doesn't warrant a cleaning in my opinion, but a visible layer of dust does, as does greasy spots, as you never know what may thrive in that grease.

Zeiss has had some complaints in the past on shoddy or cheap microscope parts. Flimsy plastic and such on the Koehler housing or some such. A gentleman in Israel if I recall bought one that was like this despite the premium model and name brand. Its there in the Microscope forum here on CN. Its a little shocking to read these remarks time and again when Zeiss is supposed to be the benchmark and none to cheap.

Last time Zi had coatings wipe away it was a $95 pair of binos from Celestron back in the 80s. Swaths of coating just came right off after a year or so.

Could the problem be limited to the ones made outside Germany? I think I have heard that there are big quality differences amongst Zeiss micro eyepieces depending on where they are made...

These eyepieces are bought directly from Germany, and there are made(I have asked that).

I have and had many Zeiss eyepieces over the decades. All of them had/have superb and very durable coatings. My latest Zeiss eyepieces have the Lotutec coating, which is also of the highest quality. None of the Zeiss coatings ever failed on me. Not even in harsh conditions with my Zeiss Marine 7x50 B/GA binoculars. Sold them when they were well over 25 years old with the optics/coatings still in as new/perfect condition. They are not quite as transmissive and contrasty as the current Zeiss coatings of course. Some progression has been made

I'd be really interested to see how the coatings look now. What cleaning method did you use? I've bought a few copies of Zeiss's microscope eyepieces and have found some design variation within allegedly the same model.

Unfortunately Zeiss is outsourcing their microscope eyepieces to China and continuing to charge exorbitant prices. I bought one for $500 with the APM adapter a year and a half ago and they really are junk. No better than some $50 eyepieces I have. As bright as the field is, I doubt they are even coated. Lots of field curvature. And yes they are the E-PL version. Stock number is 44 42 32.

I will however add that the Zeiss Diascope eyepieces are exquisite, assuming they're still made in Germany.

The original Zeiss 25mm that APM sold was the 44 41 31 - Pl 10x/18 (pictured below). It came with a TMB labeled case and had a 1.25" barrel. I purchased it from APM in 2007.

It was advertised as the TMB 25mm aspheric ortho in a Zeiss housing.
Here is what it said in the email I got from APM: "The TMB 25 mm 54° aspheric ortho in new less expensive Zeiss Housing (black version) is in stock and costs Euro 190 (at today's rate about US $ 253)"
So according to Markus (at that time) it was the same lens that went into the TMB Aspheric ortho.
Here is a pic of the case it came in:

Last year they were still made in Germany and exquisite.

I agree Erik, the best 25mm I've looked through!
