My reasoning for the 2.5x: nikon eyepieces give lower magnification on b&l systems (reducing cropping a bit on aps-c) and it does minimal-if-any compensation, which should match the center of a b&l image nicely while cropping edges where the b&l eyepieces might do more. They're also cheap and easy t...

The m1a was a bottom-barrel student scope in their lineup, even with the Wild name there is no point in buying one. Excellent construction no doubt but fixed mag. The m7a is a great scope as long as you don't need higher magnification. It can take quite nice photos too. Note the eyepieces don't focu...

I'm really glad this is working well for you. Probably close to peak performance for this scope.

It only matters if it bothers you visually or causes problems with photos if applicable. Usually the camera is pickier but you can get away with a lot too.

Yeah, the sz7 tops out at 300 lp/mm at max zoom (600 with a 2x), which puts it ahead of scopes like the stemi 508. Not sure what the minimum is. I'll try to do some tests of my own at some point a d report back. Those old vintage ads are great, and provide the best info about release dates. While do...

The Amscope/Eakins microscopes are good value for the money, but I think at some point you hit the limits of what is possible at that price point. Indeed. Amscope sells a clone of the smz800 , and while it is an impressive scope in some ways it is also extremely pricey. It's also nice to have compa...

This is a nice scope, a bit underrated by a few online sources. I set one up for a friend on a gemscope with a planapo objective and it was just great. I'd note this series has what seem to be the cheapest and most available used planapo objectives, so that upgrade is easy. They did make an objectiv...

Who did you get it from?

They're BS'ijg you. That's clearly not acceptable imo.

Just as a note, my local dealer showed me one of these lower power ones (Unitron branded but likely the same). They have a great image but I had trouble converging it, in that it felt like it took physical effort. Some stereos do that for reasons I do not know, but it isn't universal and I have neve...

Is it in live view mode while shooting?

Oh, that's really cool! Looks like a custom setup based on their forensic comparison scopes, just with a single light path.

You probably want to ask this over at photomacrography as well. This is more their wheelhouse.

One instance whwre a 3d printer, or failing that a big bix of random tubes and scraps, comes in handy. Some stereos are fine direct projecting onto aps-c, others less so. Wilds and nikons for instance seem to cover aps-c relatively well, though how well will probably vary with the objective. The geo...

I would be interested in trying this approach, but I don't know how to make that connection. The ID of my trinoc port is 26mm, and I have a T/T2 mount adapter. Can somebody point me to the part I need? Thanks. You know, I'm not 100% sure I am remembering this right, because I had a trinocular amsco...

I think plastic bowls are a popular choice.
What type of microscope is this, out of curiosity? Typically a dissecting scope would be a stereo, but this doesn't sound like any Leica stereo I know (and I think I know them all). Or is it an old Leitz maybe?

On canon dslrs you have to have the camera in live view mode to get the vibration free shots. If you're shooting that way it should be fine. This scope in general has fairly limited resolution, so there are some limits to what you can expect it to give you, but I think I got better results than this...

Yup, it's all very odd. Every time I think I have a good idea it just doesn't pan out. I've almost got my second nikon dic system set up (later version of the optiphot system) so i'll have a comparison test in the next couple weeks if all goes well.

The bh2 epi DIC is an infinity system. In contrast Nathan/Microworldofgems (@microworldofgems on instagram) currently uses a finite zeiss epi dic system which does not show doubling from what he can tell, certainly none visible in his pictures. I do think it's probably inherent to the system though-...

Makes you wonder if it's a minor variation, or something that's more dic-lite (like langastino lobsters). If I were a billionaire I'd shell out to find out because I am really curious.

Yup, if you get a look through a nice stereo you can appreciate the difference better.

Don't need no 3d printer just a press and some forstner bits

Very true, but having done it both ways I know my preference

Oh yeah, he's talking episcopic as in coaxial. The smz-u coaxial illuminator can't cover the entire FoV (as many can't) and presumably the extra 1.5x mag is to compensate for that. The quarter wave plate would have shipped with that coaxial illuminator and is part of the anti reflection system.

I haven't tried it on the smz-u but have heard it is essential to get good results, even though it is often missing on used scopes. I had one for my m420 and it did have a dramatic effect on reflections vs not using it (good control of highlights by rotating it to the right orientation). I mostly us...

Do you have the quarter wave plate?

They have lenses to compensate for the length.

The most expensive bases for stereozooms are probe stations
Close second though.
Bv, I sent an email to your beyondvisible email address, I don't think you can do PMs here yet.

I have both of these objectives, though only an SMZ-10a to put them on (plus two broken smz-u bodies, alas). I know on the later 800 series the plan apo objectives have higher resolution in addition to better color correction, but I am not 100% sure that's the case on the 10a/u series. I can check i...

Rms is just the thread on the objective. DIN is a broader spec which includes the thread (which is rms) as well as parfocal distance (45mm) and maybe some other things.

I have an smz 10. You located in the USA?

I use a meiji 2.5x photo eyepiece. Oh, there's your problem. I don't know what compensation meiji uses in their scopes, but Zeiss used about the strongest compensations of their era. The correct Zeiss eyepiece is vital to getting good photos since they are delicately matched with thr objectives to ...
