Related Questions and Answers

Q: 1. Could you use a 1.5x or 2x telephoto adapter on this lens?

A: The Fujinon MK18-55mm, being a wide to medium zoom, is an unlikely candidate for a teleconverter. Generally speaking, teleconverters are only effective on fast, high quality prime telephoto lenses. Use on other lenses is usually not successful. Mostly the issues are the lens becoming too dark for proper auto or manual focus, softening of the image, introduction of chromatic aberration and inability to mate due to conflicts in design. At this time there are only two E mount teleconverters available on the market. They are made by Sony and the only lens compatible with them at this time is the Sony FE 70-200mm f/2.8 GM OSS.

Q: 2. On a MFT cam like GH5-GH7, will the actual focal length be 36-110mm or something else?

A: Yes, when the Fujinon MK18-55mm T2.9 Lens (MFT Mount) is used on MFT, there is a 2x crop when compared to full frame.

Q: 3. 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: 4. Parfocal?

A: The Fujinon MK18-55mm T2.9 Cine Zoom Lens for Canon RF is considered a Parfocal lens with minimum focus breathing.

Q: 5. Does this lens communicate electronically with the Sony FS7m2?

A: Sorry, there is no electronic communication with the camera with these Fuji lenses.

Q: 6. 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

Q: 7. 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: 8. This wont come out for a C300 mark II right?

A: You are correct. This lens is made for the short flange depth of the mirrorless E mount standard and is thus incompatible with the longer flange depth of the mirrored camera EF mount standard. The lens, even if you were to mount it, would therefore not be able to focus on the C300 sensor. It would be too close and focus it's picture somewhere behind the sensor's image plane. The nice thing for E mount users is how this lens is smaller, lighter and speaking to it's quality and features, relatively inexpensive.

Q: 9. So , this Fuji lens is native 18MM at it's widest point , and the field of view is 69.2 degrees , which would equal 104.25 degrees if full frame , which would also be many 15mm full frame leneses feild of view , So what lens in Cine format would be the next step wider than this one in E mount ?

A: This is the widest Sony E-Mount Cinema Zoom Lens that we offer from Fujinon. They do have a Fujinon 14.5-45mm options, B&H # FUHK31X14F, however it is for PL Mount.

Q: 10. 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.
