In the review, Vega-12 with B mount and the type of mount is indicated in the marking - Vega-12B, which is not always the case. By the way, please note that the name of the lens is in Latin letters, and the mount type is in Cyrillic. Such a mixture of fonts was not uncommon in the markings of Soviet photographic equipment.

Should you buy Vega with a modern digital camera?
You know, it makes sense. 90mm is an excellent AF for a portrait photographer. Vega-12 is not the only lens option with a similar AF, but it is very worthy.
Vega-12 with its f2.8 is far from the leader in aperture ratio. For example, Jupiter-9 with a similar FR of 85 mm gives f2. But this difference in practice will not be noticeable. And the depth of field at f2 at portrait distance is so shallow that a good shot will always be a matter of the lottery.
So f2.8 is not always appropriate to use.
And if you have a Nikon DSLR and you are looking at the Jupiter-9 lens, then I highly recommend paying attention to Vegu-12.
Get a lens with similar characteristics, similar size, beautiful blur, public acceptance, but unlike the ninth Jupiter, the twelfth Vega with the appropriate adapter will fit your camera without any focal length issues.
And the price for this lens, by the way, is lower on the secondary market.
