Fujifilm X body + Leica M lens

COMPATIBLE MF MA MAC

Leica M lenses can be easily adapted to Fujifilm X cameras.

Although the Leica M rangefinder has a flange focal depth of 27.8 mm, the Fujifilm X cannot be beaten. The ring has to space 10.1 mm between the body and the lens.

Leica-M lenses tend to have macro adapters available for every system, this is the case with the Fujifilm X too. The adapter's flat rising thread increases the distance between the lens and the adapter, shortening the near focus point, which enables to use it as a kind of macro lens.

Macro adapters can be found here:

Keep in mind that using a fullframe M lens will get you a crop factor of 1.6*, because of the APS-C size sensor of the X body, you'll get a pretty high focal length multiplier (you'll get a smaller image frame). Find out more about sensors and crop factor in this article if you're interested.

Terminology

In terms of compatibility, we distinguish four separate categories:

COMPATIBLE

PARTIALLY COMPATIBLE

COMPATIBLE IN THEORY

NOT COMPATIBLE

This means that you'll be able to apply the lens on the camera in question with a proper adapter, and full focus range will be available with it (often with aperture control too). If AF is supported, you'll see it in the description.

This means that due to the flange focal depth or other factor this conversion would be normally unfeasible, but with some compromises (e.g. using a speedbooster adapter) can be made possible.

This means that the flange focal depth should make mounting and using inifinty focus possible, but for some reason there are no adapter rings available or other factors make it unviable.

This means that you won't be able to mount your lens due to mechanical incompatibility or the difference in flange focal depth doesn't make inifinity focus possible. Although numerous lenses can be mounted on cameras without infinity focus, but this cannot be considered actual compatibility.

manual focus (on the lens, with its own control ring)

autofocus available (AF controlled by the camera body)

speedbooster (focal reducer) adapters are available

macro (variable length) adapters are available

tilt-shift (or other flexible) adapters can be used
