Rokinon 135mm f/2.0 Overview

The 135mm f/2.0 ED UMC Lens for Pentax K Mount 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. On Pentax APS-C format DSLRs the lens provides a 35mm focal length equivalence of 202.5mm. Its minimum focus distance is 2.6'.

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.

Does it have an aperture lever to allow me to focus wide open and have the camera stop it down when I shoot? The picture does not show this.
Asked by: John
This is a manual lens, both the focus and aperture are controlled on the lens itself. You will be able to adjust the aperture on the lens.

question

Can I use this lens on a super 35mm digital camcorder like the Sony FS700?
Asked by: Landmark P.
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. Do note this is a fully manual lens, so you will need to set the focal length and aperture on the lens manually.

Is this lens compatible with the Nikon D3500?

Is this lens compatible with the Nikon D3500?
Asked by: Lynn
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. Do note that this is a manual lens, so you will have to focus the lens manually. However, as the lens does have an AE chip, it will provide automatic exposure metering in Auto, Program, Aperture-Priority, Shutter-Priority, and Manual modes, and the LED in the camera's viewfinder will illuminate for focus confirmation when the camera detects you have focused on your subject. It will also provide EXIF metadata to the camera.
