Lens Mount Options Growing for the Fujfilm MK Zooms

Duclos and MTF offer conversion services for the popular and cost effective cine zooms.

When the original FujiFilm MK zooms came out this spring, we loved them but were frustrated they came in only one mount, E. Clearly, the target for this lens was the exceptionally popular Sony FS7 camera. While that camera has been a huge hit and is a smart target for Fuji to cater towards, we have been hoping from the start for more choices in the mount. The company quietly released a version for its own X-mount around NAB, which is wonderful for XT2 users, but until Fujfilm gets around to launching its own X-mount cinema camera, it still is a limited selection when compared to the wide array of choices you get from something like the Sigma line.

Of course, when a manufacturer doesn't deliver something the market is hungry for, aftermarket vendors step in to deliver. In recent weeks, two well known and trusted lens vendors, Duclos and MTF, have started offering services customizing the MK zooms into other mounts.

Duclos is a well known name in lenses, running the popular blog The Cine Lens and offering a variety of services along with a tremendous wealth of information. Duclos offers a conversion to the Sony FZ mount for $500, or $400 if you also purchase your MK zoom there. The FZ mount is used on the F3, F5 and F55 cameras from Sony. According to NewsShooter, Duclos explored creating an EF conversion but it was impossible considering the current optical design of the lens.

The other option for filmmakers who want other mounts is London-based MTF Services, which is well known for its lens adapters and other hardware. MTF will convert the MKs to either FZ mount or MFT mount for £200, which works out to about $265, but for North Americans you'll have to factor in the cost of shipping. The company offers same day service, and if you hang on to the original E mount, MTF can reverse it for you in the future. However, that's not a field serviceable feature, so you'll need to send the lens back in to get it. MFT is the exciting feature here, since it should make the lens a nice compliment to the popular Panasonic GH5.

Hopefully this will tide users over until Fujifilm comes out with an X-mount cinema camera.

And so MFT users still won't get access.

The EF mount is the most ridiculous mount. You cannot attach an EF lens to another system due its flange focal distance.

Nikon for example is so versatile. Buy a full frame Nikon lens and you can attach it to all systems available via adapters.

Hunh?
EF mounts pretty easy to M4/3, E-mount and X-mount, and there's a raft of both mechanical and optical equipped adapter to do that.
The Nikon mount, PK-mount, and EF mount, are all within bare millimeters of each other for FFD, so where ever you can mount and EF lens, you can mount anything longer - Pentax, Nikon, B4 and PL.

The article clearly states the MTF (also known as 'LensAdapter') are doing a M4/3 version.

Now, if you're talking about EF-mount equipped cameras, such as the Reds and BMD's and Cion with interchangeable mounts, it's up to the user base to demand an M4/3 mount for the S35 sensor models, from those manufacturers.
Though I'm pretty sure the FFD of the Red's is done to specifically stop users from mounting unusual lens options to them.

The E-mount and M4/3 mounts are the most flexible, allowing nearly any lens to be adapted, even those which don't cover the whole sensor.

An intriguing discussion is worth comment. I think that you ought to publish more on this subject matter, it might not be a taboo matter but generally, people don't discuss these issues. To the next! Kind regards!!

Fuji really limiting their sales by not releasing an EF version. I'd have bought these by now if an EF existed.

Ditto. I would have purchased at least one of these new MK lenses had they offer them in EF mount.

Probably because if they had to make it bigger, which they would have to to make it an EF lens, it would be more expensive to produce and therefore cost more for the end user, landing the lens in a price range which would make it harder to sell due to other options.

I just bought both of them and I have zero regrets :)

Parfocal zooms without breathing at T2.9 and build in macro at that price tag.... whats not to like??!
