This review shows the lens. I96U 3,5 / 50 H-22 with the logo of the research and production association "Optics", Moscow, serial number N8102.
I did not find any significant differences between the I96U 3,5 / 50 H-22 (from this review) and I96U-3.5 / 50 with the logo of the Feodosia Optical Plant. Lenses differ only in trifles:
- different factories manufacturers
- different spelling of the name I96U 3,5 / 50 (without dash) and I96U-3.5 / 50 + commas instead of dots
- different production period
- slightly different frame
- enlightenment is a little different
- version I96U 3,5 / 50 (from this review) has an additional marking N-22
Most likely the prefix 'H-22'means a new method of applying enlightenment to the objective lenses, i.e. it's simple Нnew enlightenment. Anyone who has other data or opinions on this issue, please leave them in the comments to this review. There is also a similar lens 'I96U-H-22-3,5 / 50', produced at the Feodosiya Optical Plant (view).
Sample Photos
On camera Canon EOS Digital Rebel XSi I used a lens with two adapters: M42-Canon EOS + M39-M42. Some photos were taken using macro ring M42 different thickness.
I96U 3,5 / 50 H-22 does not have a focusing ring. It is impossible to focus with this lens in the usual sense of the word. The lens is always focused at a certain distance. It is very convenient to focus by moving the camera towards or away from the subject. It is very convenient to use I96U 3,5 / 50 H-22 with macro rings different thicknesses, which allows you to change the focusing distance and magnification.

Use with modern cameras
Lenses with an M39 mounting thread (for enlargers, M39 X 1 / 28.8), such as the lens from this review, are very easy to use on modern cameras, just select correct adapter. On lens reflex cameras can only work in macro mode (shoot small objects with a short focusing distance). On mirrorless cameras, it will be possible to achieve focus on infinity. The cheapest adapters can be found aliexpress.com.
For use on modern digital SLR cameras Canon EOS need M39-Canon EOS adapter, you can buy such an adapter (adapter) here. Also, an adapter M39-Canon EOS can be easily replaced with two adapters: M42-Canon EOS + M39-M42. In any case, the lens will always be focused at close distances.
An adapter is required for use on Nikon SLR cameras M39-Nikon F, you can buy such an adapter (adapter) without a lens and a chip here. Also, one adapter M39-Nikon F can be easily replaced with two adapters: M42-Nikon F + M39-M42. In any case, the lens will always be focused at close range.
For such a lens, I advise you to additionally buy macro rings with M42 thread, for example here.
How to use this lens with cameras of other systems (Pentax, Sony, Fujifilm, Olympus, Panasonic, Samsung, Sigma etc.) - ask in the comments and you will be prompted. If you have any questions on compatibility and adapters, ask in the comments (comments do not require any registration at all, any user can add a comment).
