Related Questions and Answers

Q: 1. The M4/3 version with a passive adapter could allow this lens to work on a Sony E Mount too?

A: This could work with a Micro four thirds to E-mount adapter, though it may present issues with maintaining infinity focus.

Q: 2. Is there anyway to use this lens with an EF mount

A: There is not. You cannot adapt an MFT mount lens for use on an EF Mount system.

Q: 3. Will they come out with a PL mount? EF? That would be nice. I would buy one right now...

A: No, since this is designed from the get-go as a E mount lens, it is impossible to adapt it to EF or PL. Even if you were able to mount it, the lens could not focus. Since Fujinon did not have to allow for the space of a mirror, it was able to make the lens much smaller and cheaper. For EF/PL it would have been much more expensive.

Q: 4. The sony E version weights 2.1 pounds but the RF version weights 4.4lbs? Is that an error ?

A: The lens weighs 2.2 Pounds. Our apologies for any confusion our web team will update the website shortly.

Q: 5. Is there a 1/4-20 mount on the bottom of the lens to use with lens support of this kind?

A: There is none. I suspect since the lens is made of composite materials and is consequently very light at only 2.16 lb / 0.98 kg, no provision was made for a rod lens support. Less gear is helpful in a one person band for speed and weight and it works hand in glove with the Sony FS7 Mark II with the stronger E mount. However, I hear you so you could always set up your 15mm rods and then support the lens with this: Tilta 15mm LWS Rod Lens Support B&H # TILST05 or this Wooden Camera Universal Lens Support (15mm LWS) B&H # WO175400.

Q: 6. Is the mount on the MK lenses interchangeable? Say, if I have the E-Mount version. How could I change it to MFT mount?

A: MTF Services Ltd offers B&H # MTFUJIM43 , which is a Micro 4/3 Mount for Fuji MK Lens. This allows you to convert this lens to MFT mount. https://bhpho.to/2sqfi60

Q: 7. Do you need to adjust back focus at all to get the lens perfect parafocal throughout the zoom? Shims etc

A: When working with different cameras, even if the mounts are the same, it is always safe to test your back focus before your shoot to ensure the lens focus is correct. No shims are required to adjust the flange focal distance as this lens has a built-in adjustment mechanism

Q: 8. To be clear, I can switch mounts between E and MFT with the help of MTF Services but can not do so on the X version of this lens, right ?

A: correct because of the difference in Flange distances between E, MFT mount and Fuji X you can not change this to an X mount here are the flange distances for the mount systems E mount:18 mm Micro Four Thirds System: 19.25 mm Fujifilm X-mount: 17.7 mm

Q: 9. is there a small mattebox that will clip directly onto this lens? I noticed it flairs very easily

A: This lens has an Outside Diameter of 85mm. The Wooden Camera 4 x 4" Filter Zip Box for 80-85mm Exterior Diameter Lenses is a great choice, B&H # WO231400. They even offer a kit with one top and two side Clip-On Flags to further help block light. https://bhpho.to/2w9MjIl https://bhpho.to/2rh4XsM
