Featherweight. The first thing you’ll notice when you pick up the Fujinon MK18-55mm T2.9 for Sony E is that it’s beyond light. Weighing in at just north of 2 pounds means that this lens can be mounted without the need of an additional lens support apparatus when needed. It also makes it a prime candidate for gimbal work.

High Quality Optics. The lens features a fast T2.9 clickless aperture, controlled by nine rounded blades. It is color matched to compliment higher end offerings from Fujinon, and the 28.5mm diameter image circle covers the APS-C / Super35 sensor format.

Cine Style. Unlike many other Sony E-mount “cine” lenses, the MK18-55mm is truly a cinema lens with a full cinema feature set. The focus, iris, and zoom rings all have a industry standard 0.8 gears. The focus ring gives you precise control over pulls and follows with 200° of rotation, while the iris ring is declicked with a smooth action allowing you adjust exposure mid-shot. There’s also back-focus tuning to keep what’s in focus precisely sharp and a macro adjustment to get up close and personal with any subject.

Parfocal This term is thrown around a good bit, but many lenses that claim it are not truly parfocal. Instead, they’re close enough that many won’t notice. Well not this one. The MK18-55mm is a true parfocal lens.

Q & A

Are there any flare issues I should be aware of?

• When shooting in bright sunlight and stopped down past T11, you may see a colored spot in your footage. That’s the sun reflecting off the sensor and then back off the rear element, causing an unwanted internal reflection. It’s just a part of the design. It’s best to shoot at larger apertures and use an ND filter instead.

Should I use additional support with this lens?

• We recommend using a rail support system and lens support. We have provided links to our universal baseplates in the “recommended” column. When in doubt, please contact us at 877.578.4777, M-F, 9AM-5PM EST or at service@lensprotogo.com..

Will this lens cover full frame?

• This lens is intended only for use with crop sensor or Super35 sized sensor cameras and camcorders. It will not cover a full-frame sensor.
• If you plan on using this lens with a Sony A7 series camera, like the A7S, A7R II, or A7S II, please be aware that it is only compatible in crop mode.

Does it come equipped with focus gears?

• Not only does it come equipped with focus gears, but also geared controls for iris and zoom. Each features an industry standard 0.8 pitch.
