Rokinon Xeen 50mm T1.5 PL Mount Lensis built specifically for use as a cinema lens, and is not a modified still lens. It features an internal focus design so that the lens does not change size while focusing, minimizing breathing. Each lens in the Rokinon Xeen cinema lens set is multi-coated for good contrast, glare prevention, and are color matched to a factory standard, allowing you to assemble a set over time with minimal color shift. This 50mm lens provides what is considered a normal angle of view on full-frame cameras, and a tighter angle of view on smaller formats. The lens features dual sided focus scales in feet, with dual sided iris scales. The 11-bladed iris provides a rounded aperture for a natural looking highlights and Bokeh.

The lens is a manual focus and iris lens, and does not have auto focus or auto iris capability. It incorporates cinema-style focus and iris gears that share the same position across the lenses in the Xeen set. The common 114mm front diameter allows for quick lens changes when using a matte box and focus accessories. The focus ring rotates 200° from close focus to infinity; this gives you a high degree of precision and consistent focus.

Dual calibrated right and left side focus and T-stop scales allow your focus puller to work from either side of the lens, without having to flip the lens in the mount.

Each lens in the Xeen series share common focus and iris gear ring positions, which speeds up lens changes as accessories such as follow focus units or iris motors don't have to be re-positioned.

Q: 1. If the EF Mount version is adapted with a Metabones adapter onto an FS5/FS7, Will that difference in distance from rear element to sensor throw off the distance marks on the lens barrel for focus?

A: We do not believe it would throw off the distance markers. However, this lens is available with an E-Mount, B&H # ROXN50NEX, you may want to use that model instead for a direct connection to the FS5 or FS7.https://bhpho.to/2HeeiuH

Q: 8. Why are these Rokinon lenses costing almost 10x as much as the Canon mount versions?

A: That is a fair question.The difference between consumer and pro level cine style lenses comes down to functionality on set. In order that the exacting work of movie making be as efficient, reliable, and consistent as possible, there need to be certain design parameters. 1. Excellent resolution, color and contrast image quality that all lenses in the line match. This is so you can cut between them in editing and not waste time making sure each lens seamlessly has the same look.2. A big barrel is needed by the 1st Camera Assistant for precise focus control.3. A common size front diameter is desired so the matte box fits all of the lenses quickly, without fiddling with adapters. The placement of the gears on the lens must be in the same place so less time is used on set adjusting follow focus devices and remote motors for focus and iris. Finally, similar weight lenses mean less time balancing MoVI, Steadicam and other stabilizing devices.4. The DS line has 8 iris blades which is good for bokeh. The Xeen line has 11 blades which is better.All of these parameters cost money. As you go in the filmmaking world, you will see the benefits they provide.
