Compounding this problem is that the lens mount adapters out there for these two mounts all add some thickness into the mix. This means that when we put the lens onto a Nikon camera, the film plane will appear too far away, and the image will form just ahead of it. These numbers spell trouble: the FFD of the Nikon F-mount system is longer than the system the lens is designed for. This is where some added complication for Nikon conversion comes in. It is the distance between the flange of the lens mount and the film plane. The flange focal distance is particular to each lens mounting system. However, there is a "gotcha" in that the flange focal distance is different between the mounts.
There are adapters available cheaply from the usual suspects which M42 lenses will thread into, converting them straight to Nikon F, mechanically. Fortunately for me, this is about as easily said as done. Not having any cameras that take M42 lenses, I set out to adapt and (reversibly) modify this lens to work with a mount I can work with-the Nikon F mount. These lenses were made in the USSR, and the example I got was made for the M42 screw mount. Near the end of 2019, I purchased one of the notorious Helios 44–2 58 mm f/2 lenses. Looking forward to using it more as the snow melts! Volna 9 is a bit more expensive it seems.Written: Helios 44–2 lens for Nikon F mount Simple 1983 USSR 58mm f/2 lens modding Speaking of Industar 61 L/Z I just picked mine up at the post office today, bought strictly for macro work and the off chance for star bokeh. Speaking for myself the only reason I haven't bought modded versions is that I plan to get a mirrorless backup camera (a7/A7ii) so I wouldn't need infinity on Nikon F. I've not tried 44-2 with infinity but 81-H or N as you say is razor sharp! I find that one easier to focus than the older 44-2s. I didn't pay that much for mine a few months back, definetly a good lens. But quite a bit cheaper than a modded 44-2. Not taken as such at all, it's a bit more than a 44-2 on an auction in general. But they are good macro-lenses and especially the 61 L/Z is so small that it easily gets a spot in the camera-bag I actually rarely use them for this, although on occasion it can give really nice results. I like to compare it with the Industar 61 L/Z and Volna-9 macro-lenses, which have the star-shaped bokeh at intermediate apertures. And my personal experience is that "one trick ponies" will not get much use after some initial fun. Infinity-focus, or even focus up to 5 meters or so, adds a lot of versatility to a lens.Īlso, stopped down, the Helios-44-lenses are very good and versatile lenses. So if the sole purpose is close up portraits and bokeh-fun I'd go with the cheapest possible solution (original lens + adapter). You wouldn't use infinity any way, but you would need a cheap adapter ring just to mount it on your camera. It is fair to mention that infinity is not a must have for these lenses if all you're looking for is the bokeh. O I didnt mean to "attack" the 81-N (the Cyrillic letter "H" translates to the latin "N"), I simply have no idea of its availability or pricing That's a really good tip! But again, the 81-H already does fully work on Nikon cameras, maybe I'm BIAS since I love mine That's true, forgot about that! He provides them if contacted though, I noticed he had several versions in his store rn.
