The 135mm f/2.0 ED UMC Lens for Nikon F Mount with AE Chip from Rokinon is a manual focus telephoto prime lens useful for portraiture and all medium telephoto applications. Its fast f/2.0 maximum aperture is effective in low light and enables shallow depth of field control. With a rounded 9-blade diaphragm, shallow depth of field imaging will be rendered with pleasing out-of-focus highlights. Compatible with both FX and DX format DSLRs, it provides the 35mm focal length equivalence of 202.5mm when used on DX cameras. Its minimum focus distance is 2.6'.

The Nikon F-mount version of this lens features an AE chip that provides auto exposure metering in Auto, Program, Aperture-Priority, Shutter Priority, and Manual modes as well as a focus confirmation in the camera's viewfinder when focus has been reached manually. 

The optical design includes one extra-low dispersion lens element to control chromatic aberration, contributing to sharp, color-accurate imaging, and each of its lens elements features Ultra Multi-Coating to improve light transmission and reduce ghosting and flare. An internal focus system prevents the front end from rotating which allows more effective use of variable filters.

A durable metal barrel with a wide focus ring and manual aperture control ring offer tactile control over focus and exposure. An included, removable lens hood deters stray light from entering the lens, while protecting it from accidental impact and precipitation.

A: The Rokinon 135mm f/2.0 Lens for Nikon F Mount with AE Chip is compatible with both the D800 and the D5300. Do note that there is a 1.5x crop factor when using this lens on the D5300, so the true focal length will be approximately 202.5mm.

A: Yes, the Rokinon 135mm f/2.0 Lens for Nikon F Mount with AE Chip is compatible for use with the Nikon D3500 DSLR camera.

Q: 8. Has anyone had trouble with airlines using this as carry-on luggage? The size is listed as 23 long (1 more than most airlines allow ), but when I measured it it comes out to 25 long.

A: Its 25. Unfortunately that means it has to be checked in. But depending on what set up you have, the bag does have a squish factor that will allow you to squeeze the bag into the measuring bins at check in. I would call the airlines to make double sure you can take your precious cargo in the cabin with you I would hate to hear your camera was damaged in cargo.

Q: 9. Can I use this lens on a super 35mm digital camcorder like the Sony FS700?

A: As the Sony NEX-FS700R Super 35 Camcorder uses the Sony E-mount, not the Canon EF lens mount, the above lens would not work for your needs. Instead, you would need to purchase the Rokinon 135mm f/2.0 ED UMC Lens for Sony E MountB&H # RO1352SE, for use on the Sony NEX-FS700R Super 35 Camcorder.
