In general, things are equivalent if the photo is clear. But is it clear at such large magnifications? Optics, after all, are cheap...

I make a drawing from a photo (b/w with feathering) - roughly speaking, I circle the contours, the main thing is that the proportions are observed, and drawing by cells is a thing of the past smile.gif.

Yeah... we should try it. On the cells, probably longer, but you can go to chistovik immediately. And so how? on the printer, then on thick paper through the glass?
tell us? smile.gif

At the highest magnification of 100x normally, clearly, I, however, do not know how IchMan takes photos, but I think everything turns out well smile.gifHere if you additionally increase (by 200), the field of view decreases, the working distance also decreases, there is alreadyfrown.gif

Dear Dzanat, to be honest, I doubt that at high magnifications on the discussed models of microscopes, clear photos will be obtained. First of all, you can't put a digital mirror on such binoculars. There are still amateur cameras with rather noisy matrices. Then the whole optical system: it is clear that with a large number of lenses and at high magnifications, very powerful lighting will be required, and the image will blur (due to light scattering in the lens glass and light re-reflection; always the larger the magnification factor, the more any aberrations). Note that no one specifically designed Wuzhou optics and digital soap boxes for each other. And once again, I note that these optics are cheap, with an incomprehensible build quality. In general, I strongly doubt that photographing with the subsequent outline of small objects will replace direct drawing (by the way, with a certain skill, this does not take long at all). If colleagues who practice the first method share specific results, I would be grateful.

By the way, I think you have MBS-10. Where does it get 200x?

Yes, I'd like to see the results, too... but still, probably, a lot depends on the objects. I, for example, do not twist it, you need to draw and watch at the same time, what and how there... there will be a lot of ambiguity in the photo. smile.gif
I almost forgot smile.gif))

Yes, from where? There seems to be already 100x full seams.

How does it show with this magnification?

How does it show with this magnification?

it shows normally. It is more necessary for working in transmitted light, but in principle we (beetle experts smile.gif) do not need it...we have a pin 4cm, and the slave is spaced. there's 2.5 cm....yes, and at 100 everything is visible....

Have any of the forum participants worked with Citoval 2 Carl Zeiss Jena?


It's interesting to me, but you can go to St. Petersburg (Lensoveta str. d. 73) and compare for yourself:

you can tell us later.
