FotodioX M42-FXRF-PRO-MACRO-V2 Overview

The M42 Screw-Mount Lens to FUJIFILM X-Series Camera Adapter with Macro from FotodioX is an all-metal adapter that allows you to connect a M42 screw-mount lens to a FUJIFILM X-series body. It is designed for macro focusing, featuring an extendable helicoid that covers focus from infinity to close distances with variable magnification ability depending on the lens. For mounting, the adapter comes with chrome-plated brass mounts that help ensure a tight fit and connection.

Please note that this is a manual adapter, and so any electronic communication between the lens and the camera is disrupted. Any lens without a manual aperture control ring will stop down to its smallest f-stop by default. Manual exposure and metering are still possible with your camera's aperture priority mode.

Works beautifully..

I bought this to use with a favorite vintage lens, a Fuji 55mm f2.2. On my Fuji x-T3, the new adapter's enhanced focusing range, made possible by the built in helicoid, has made the old lens much more versatile and fun to use. My copy locks into the camera mount perfectly. Others have found it insecure but mine is okay-fine.

Doesn’t even lock onto camera body

The m42- Fuji X mount adapter works well it have near the proper spacing for infinity focus (it’s slightly more than completely closed for most of my lenses). And functioning and quite smooth Helicoid (it did have a cast amount of machine oil when I first opened and extended it but nothing to be concerned about) But the drawback and honestly deal breaker for me is that it does not lock into my camera I can turn and twist it on and off with out having to press the release. Meaning I have a small space where dust and the elements can go in and inedibly damage my sensor and atop of that it’s quite easy to take the lens off with out unlocking it (because it’s already not locked in) making it a potential danger for your lens.

Thanks for the previous answer but that was not what I was asking. I was asking about compatibility. Fotodiox makes a distinction between Type 1 and Type 2. The answer on the other adapter to a question about compatibility was this: "Possibly, If the aperture pin of your M42-mount lens depresses all the way down, your lens is considered type 2 and this V2 lens mount adapter is compatible with it. However, if your M42-mount lens has no aperture pin, tabs, or levers; or if it has an aperture pin that does not fully depress (small tabs stick out), it is considered a type-1 lens and is compatible with V1 adapters (available separately)." Do I need to worry about that distinction with this adapter?
Asked by: Kevin
No you don't need to worry about that distinction with this adapter. The adapter is listed as compatible with both M42-mount types.

Other Fotodiox M42 adapters specify Type1 or Type 2 depending on if the the lens has an aperture pin or if that pin depresses all the way down (e.g. see Q&A on FotodioX M42-FXRF-V2). Is that the same for this adapter? Thanks!
Asked by: Kevin
The Fotodiox M42 has no coupling or manual way to control the 42mm lens. The aperture and focus must be controled by you.
