Monsters
Helios 40, Red П 85/1.5 (13 blades) and Carl Zeiss Jena Biotar, Red T 58/2 (17 blades).
There is not a huge difference between 58mm and 85mm, but as you can see a massive difference in the size of these lenses, mostly due to speed. The Helios 40 is not only big but very heavy. But they are both monsters in their own ways. (Any lens with 17 blades deserves that accolade).
These are early versions. The Biotar probably the earliest version, and the Helios 40 the second version of the "pre-production" run, given its rotating tripod collar. Both lenses went through later design changes, including a reduction in numbers of blades.
Taken with a Helios 44-2 - the Russian grand-son of the Biotar (following the earlier Helios 44).
