No, one Soviet lens for a 1:1 scale is definitely not enough.
We need more macro rings.
Or even better, use 3-8x microscopic lenses for small items.

And, if you connect the Japanese (canon 100mm macro)+industriar. how do you think the picture will turn out?

One may not be there (although in fact there is, but with a gemor), but two identical faces to each other-there is. Back at the standard distance from the matrix, we get an image of the object located at exactly the same distance from the front exactly in scale 1:1. It is better to use tessars for this purpose (i.e., in Soviet terms, industriars). The pair Industriar-90U works very well. Rings will be required to bring the rear lens to the regular working segment, it is quite large. As soon as you focus it on the infinity pole-minus bast shoes, attach the front one. Their muzzle is smooth cylindrical, you will need a piece of some plastic tube of a suitable diameter. You can also use the thinnest M39 macro ring for this purpose, just add a little bandage made of electrical tape to the muzzles.

Cheap microscopic lenses have two significant drawbacks - a curved field and the inability to aperture. For a laboratory survey with subsequent stacking, this is good, but not so much for a field survey.

Ilya, how is the situation in Donetsk right now?

Approximately as they say on the new hundred Russian channels. The only thing they probably lie about refugees is that they have already counted about a hundred thousand people, but there are not many fewer people and cars on the streets (unlike in August 2014, when Gord was really almost empty). Shootings, cars blow up, with victims. But in 8 years we have already got used to it. Many hoped that Russia's recognition would immediately force the APU to calm down, but no. It seems that the conflict will not be resolved without a new round of intense fighting. It remains to be hoped that it will be short-lived, devastating for Ukraine and will not end with another Minsk agreement. Let's see if the vaunted Russian wunderwafleys are really that good...

Several materials about micra 4/3 (critical):

Please tell me about the following question. I want to shoot my collection as efficiently as possible (and at the same time inexpensively). The smallest bug has a size of 2-3 millimeters (I attached a photo in comparison with a match).



The best thing that has been done so far is to photograph it on an iPhone through the lens of a BM-51-2 binocular microscope (I also attached the result).



I don't like the fact that the legs and antennae are not sharp, but it is impossible to achieve the best with such a "setup".

I'm still considering two options:

1) Purchase of the Adonstar AD407 digital microscope (https://ozon.ru/t/PzkVaPJ
2) Buying a used Canon eos 1000d camera with a Canon EF-S 18-55mm f/3.5-5.6 IS STM lens ~ 14 thousand rubles

Will any of these options allow you to achieve a better option (more detail and clarity across the entire depth)? Or is there something better for comparable money?

I don't know anything about a digital microscope, but a DSLR with a whale lens doesn't work at all. For small things at an inexpensive price, the Soviet biological microscope (MBR, MBI, Biolam), slightly modified in terms of lighting, is suitable, always with a 3.7 X LOMO lens in combination with a mirrorless camera. A DSLR will also work, just the mirror will hang around. You can keep within 10 thousand rubles. (if you are looking for urgently) or 5, if you are not in a hurry to wait for favorable offers at flea markets. But focus training will have to be mastered without fail.







P.S. I read about BM-51-2 - an interesting thing, in theory, should be better suited for photography than MBS, since it has completely separate optical channels. But the eyepieces aren't removable, are they?

ENO Thank you for your advice!

The eyepieces of the BM-51-2 are just the same removable
