You just opined: ' not the sellers problem'...well then my sense is : why should I gamble with spending monies in a market where: 'sellers have no control/ no idea of final costs of items they market for sale? I think what you described were not customs fees, but add ons on the seller's end which s...

This isn't super unusual. It's typically meant to act as a finder objective for a 100x oil objective.

It has never once been an issue for me. You might get some sort of customs bill via fedex or ups later on. Zero ssn involvement.

A related question…how “good” are Lomo objectives?

I am considering adding to my objective collection.

Thanks

The 3.7x is weirdly great for macro shootin'.

That's usually a good way to sell it for the starting price if at all. Demand for these sorts of objectives is rare and occasional.

Could I use Cyanoacrylate

No cyanacrylate near lenses, the vapors can fog them.

Good find! Alas, at least the stereos on their site are standard Chinese offerings. Then again even Meiji is selling some Chinese scopes now.

Depends if you mean the intermediate illuminator attachment or the illuminator built in to the m450

Report isn't working. Oliver is it possible to remove the ability to change text size and color, these spambots are the only ones using it.

His more recent ones are mostly with his Zeiss but he did a ton on the AO too.

User Microworldofgems has a complete set and has published some amazing pictures from it.

That is very true about eBay--it's extremely expensive to sell there.

Being located in Russia probably makes ecommerce difficult right now. Actually he lists his location as Belarus. Given the proximity to Russia etc it could impact delivery. Although that did not seem to be the case with me. From what I have heard they are made in Belarus but he is in Russia, which ...

It depends what you're doing and how it's equipped. My E800 is absolutely amazing but I have to admit I don't use it that much since I rarely look at alides and haven't ended up starting.

Within a system it may not vary as much, but typically when you move up to the higher tier of objectives (nikon HR, Leica 65mm series etc) working distances drop and resolutions increase since they need to handle higher max magnifications. The resolution on the 1x plan apo on my M10 knocks my socks ...

Very nice! Those achromats are OK and all but the atep up in going to a good plan objective is pretty big.

Not nearly as relevant as Apo's, but I've done a few head to heads between Mitutoyo objectives and Chinese clones. Mitutoyo isn't one of the traditional big four but they're the big dog in their niche of long working distsnce metallurgical objectives (to the point Nikon has copied their standard for...

I think for something to qualify as a 'Zeiss knockoff' it would need to copy an optical system that Zeiss developed, not just be another company whiteboxing from the same optical pool. I guess some do attempt to look like the Primostar line which kind of counts though.

That's a Zeiss-branded Chinese Olympus knockoff though. It iwn't related to any of Zeiss's other in house systems.

I bet your new one is a short barrel. I have one that looks identical which is this way, if so it wants to it a lot lower than your other objectives. Mine also performs very badly.

Yes, the working distance range is part of the spec, though chinese suppliers don't always provide that information.
A good alternstive is a dual gooseneck 100w halogen illuminator or modern LED equivalent. The poseable arms are nice for directing light where it's needed.

But to follow up on the last point you'll likely get acceptable to good results with a wider variety of objectives than you'd expect.

Mu purpose is seeing bigger field of view. For example when scanning 15mmx15mm area, I have to take 650 photos (0.75mm x 0.55 mm). If I see bigger area for example (like 0.85mm x 0.75mm) I need less image and as a result less time to scan a tissue Of course, but if you're stitching the edge/corner ...

Back in the day film type was a major consideration as well. Having two cameras would allow you to have multiple options on that front. Having access to the infinity image on the aide port allows for adapters using shorter or longer tube lenses rather than a tube lens plus a reducing or expanding le...

I don't know what your exact needs are. There may be vignetting from the 0.35x adapter (most likely) or from the objective. Direct projection onto full frame with a suitablr tube lens might have better odds of success (since you'd not have any reducing optics in the light path) but you'll definitely...

That'd be asking for a 37mm field number from your objective (13mm sensor diagonal * 1/0.35). The adapter may not even project an image big enough to cover a sensor that size. There's a chance your objective will cover it though, some Olympus objectives can cover full frame sensors with direct proje...

Great job! I would not mess with cleaning, your photos aren't showing major signs of lowered contrast which is what you'd expect from dirty elements. I'd say your equipment is dialled in well enough--now the fun bit, finding subjects and fine tuning your lighting and editing skills.

The neo splans are meant for looking at opaque subjects with nothing transparent on top of them. That matters less at lower magnifications, but at higher magnifications you will get bad results looking at pond life. In terms of optical quality, when set up with the correct optics (an extra lens is n...
