I have a Helios 44–2 lens lying around for a long time (like many). And I’ve been using a Fujifilm X‑T30 mirrorless camera lately. And so I decided to try to shoot on the old Helios. To do this, I ordered an M42-FX adapter on Aliexpress, with which Soviet optics can be put on a modern camera.

Aliexpress has a fairly large selection of different M42 adapters, from very cheap to quite expensive. But in fact, they have the same functionality, since this is just a ring with the bayonets and threads we need. I chose the medium priced option. Focused primarily on reviews.
Delivery of the lot took almost two months. But since it’s not a necessity, I didn’t get too upset.
The adapter arrived in such a simple box:


The kit here consists of an adapter and a hexagon, with which you can turn the outer ring for more convenient positioning of the lens:

The adapter is arranged quite simply. On one side there is an M42 thread for screwing in a Helios lens (or another Soviet lens with an M42 thread), and on the other side there is a cutout for the FX mount (Fujifilm)


The adapter does not have any chips or electronic components. On the side of it there is only the inscription M42-FX:

And this is how my copy of Helios 44–2 looks like:

With a simple movement, without any problems, we wind it onto the adapter:


And then put on the camera:


Using the supplied hexagon, we loosen the outer ring of the adapter, which is held on by three countersunk screws, and turn the lens so that the risks on it are on top and they can be seen:


All. You can shoot. Almost. In Fujifilm cameras, you still need to enable work without a lens. In my case it looks like this: go to settings-general-button/disk settings and there in the paragraph “shoot without a lens“set” on “:

All. Now you can shoot masterpieces.
Well, in fact, there are plenty of examples of how Helios lenses are shot on the net. It all depends on the directness of your hands. My arms are honestly not very straight for a photo, but below I will show my examples:
Subject shooting, flash illumination:




Street shooting, natural lighting:






As for me, the result is very pleasant. True, there is one minus. Helios 44 is a manual lens, and you won’t be able to take pictures on the machine. You need to manually adjust the aperture and focal length. And with not very much experience, some of the frames will turn out to be blurry due to the fact that the focus did not hit. It’s bad that with this adapter there is also no focus point confirmation (it happened on Canon), but as far as I understand, this is not generally the case on the Fujifilm system.
Conclusion:
Of course, I do not urge you to run and buy such adapters and start using old lenses on modern cameras. The process of shooting with manual glasses is very amateurish. Here it will not work just to press a button and get a good frame, here you have to catch a focus, a frame for a long time, and hope that the picture was a success. It is rather necessary for gaining experience, well, for fun. The process here is very meditative. The quality of the optics is generally very good considering its price. In general, I was satisfied with the purchase.

Therefore, you can easily choose the right adapter for your camera and, for example, by buying an old Helios (or, for example, industrial, jupiter, zenitar, etc.) at a flea market, try the old optics on your camera.
