The 50mm T1.5 AS UMC Cine DS Lens for Sony E Mount from Rokinon is a fast manual focus prime lens. It is compatible with APS-C and full frame E-mount cameras, having a full frame focal length equivalent of 75mm with APS-C sensors. 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. O ptimized for cinema and video applications, t he 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.

Compatible with both full frame and APS-C format E-mount cameras, this 50mm manual focus prime lens provides the 35mm focal length equivalent of 75mm on Sony E mount APS-C format cameras.
Functional as still photo lens but optimized for cinema and video shooting with geared aperture and focus rings, de-clicked aperture for smooth exposure transitions and laterally printed aperture and distance markings. The 50mm T1.5 is part of the DS series of cine lenses, sharing characteristics and features that unify the series and make it easier for users to swap out lenses when shooting video. Each DS lens provides aligned focus and aperture rings so that readjustment of the follow focus is not necessary when switching lenses. Also each lens has been tested to match color and contrast for a consistent look and less potential post-processing. Finally, all DS lenses print focus scales on each side of the lens barrel for ease of use from both sides of the camera.

Rusty LOVES them.
Size: Large
Our dog loves these balls! I like that they squeak and the texture prevents them from getting slimy from his spit. They last more than smooth balls. You do need to make sure you get the right size for your dogs mouth.

Squeaker Does NOT Break in a Day
Size: Large
My mid-size, 40lb heeler mix loves these chew balls. They are easily his favorite toys to fetch, chase and chew on. We’ve had the chew balls for several months, and, unfortunately the squeaker does not break in a day. They are still going strong. Extremely durable and great value for the money.

Very durable, even after the squeaker quits
Size: Large
These balls are really durable! The squeaker inside only lasted about a week, but my dog loves to chase it and just chew on it in his mouth. I took two of them to the dog park, and the other dogs were the same way with them.
