The Industar 61 is another vintage Soviet Union lens that I’ve paired with my Fujifilm X-A3. This lens came attached to a FED 5c 35mm rangefinder that I purchased for $40 a decade ago. I really appreciate the photographs that I’ve captured with it on the film camera. I used to also pair it frequently with an X-E1 that I once owned. It’s an excellent lens with plenty of character.
My Industar 61 was made in 1983. It has an M39 screw mount (some were made with a M42 screw mount) and a focal length of 55mm (some versions have slightly different focal lengths). Because of the crop factor, it has an equivalent focal length of about 82mm on the X-A3. Even though it was intended as a “standard” lens it’s more of a “portrait” lens on the Fujifilm camera. The maximum aperture is f/2.8.
This lens is a German knockoff. It’s basically a modified Leitz Elmar 50mm f/2.8. It is very sharp but with some significant pincushion distortion. It’s known for “soap bubble” bokeh, which is highly sought after by some photographers. There is a radioactive coating on the lens, and that might frighten some people, but it’s safe to be around, since only a tiny amount of Lanthanum was used in the production. I find that it delivers a slightly warmer tone than other lenses, even on digital cameras.
What’s great about pairing the Industar 61 with the X-A3 is that it’s a small and lightweight setup. The lens is smaller than the kit lens that came with the camera. It sticks out about as far as the X100F lens does with a lens hood. It can fit into a large pocket. I’ve carried the X100F in one jacket pocket and the X-A3 with the Industar 61 in the other. It’s great for travel or street photography.
You can find Industar 61 lenses for next to nothing (and the adapters are usually about $10), and for very little money you can add a quality manual-focus prime lens to your camera. No doubt about it, I’ve gotten my money’s worth out of this lens and then some. While the Industar 61 isn’t my favorite lens to attach to my X-A3, it’s still a good lens that certainly has its place.
