This B&H Kit provides four lenses that you can use to shoot images from wide shots to portrait; it includes Rokinon's 16mm, 35mm, 50mm, and 85mm Cine DS Lenses for Nikon F Mount that feature sharp optics and similar physical characteristics for fast lens changes. The 16mm lens covers APS-C-sized sensors and features a maximum T-Stop of 2.2. The 35, 50, and 85mm lenses share a T-Stop range of 1.5 to 22 and cover full sized lenses. The lenses are suitable for shooting using available light, and as they all share the same exposure range, there is no worry when changing lenses you will also have to change your lighting or camera settings.
Aperture and focus scales are marked on both sides of the lens, which makes it easier for a focus puller to work either side of the lens. The lenses feature a multi-layer coating providing good contrast, a sharp image, and protection from veiling glare. Industry standard focus and iris gear rings share a common position across the lenses for quick lens swaps when working with lens accessories such as follow focus units. Focus and iris are manual only with no electronic focus or iris control by the camera, and the iris ring is de-clicked, which allows you to make smooth iris pulls during a shot.
For mirrorless shooters, or anyone that needs to cover a Super35 sized sensor, this Rokinon 16mm T2.2 Cine DS Lens utilizes a multi-layer coating process for consistent color rendition from lens to lens. With consistent coatings the lens answers the challenge of assembling a set of lenses over time. The lens comes in Nikon F mount, and it features industry standard geared focus and iris rings that share common position with other Rokinon Cine DS lenses.
To aid focus pullers who have to work both sides of the lens, the aperture and focus scales are marked on both sides of the lens. A removable petal shaped lens hood provides flare protection when shooting without a matte box, and the lens's threaded front accepts 77mm filter rings.
The 50mm T1.5 AS UMC Cine DS Lens for Nikon F Mount from Rokinon is a fast manual focus prime lens. It provides a very fast maximum aperture of T1.5 for effective low light capture and shallow depth of field control and an 8 blade iris for attractive bokeh. Optimized for cinema and video applications, the focus and aperture control rings are outfitted with industry standard gearing, which provides an interface for working with a traditional follow focus. The aperture control ring has also been de-clicked, which enables smooth iris pulls. In addition, bright aperture and distance markings are printed on the lens barrel facing laterally to facilitate easier control by a focus puller.
The 50mm has a minimum focus distance of 1.5'. Internal focusing minimizes the effects of lens breathing, which insures a more consistent angle-of-view when adjusting focus. The lens is composed of 9 elements in 6 groups, including one aspherical element and one hybrid aspherical element to reduce aberrations. In addition, a lens multi-coating helps to improve light transmission reducing flare and ghosting. The filter thread diameter is 77mm.
With this 50mm lens, Rokinon introduces the DS series of cinema lenses, unifying their cine lenses in more than just name. Each of the DS branded lenses will offer the same alignment of their geared focus and aperture rings so that follow focus and other rig accessories won't need re-adjustment when swapping lenses. Also, each DS lens is tested to be color matched with the other lenses in the series and provide the same color and contrast when shooting video. Lastly, the lenses are marked with focusing scales on each side of the barrel for easier adjustment from either side of the camera.
