The 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens for Nikon F Mount from Rokinon is a lens optimized for digital cinematography and as such provides a de-clicked manual aperture for smooth and silent adjustment and unified focus and aperture gears for use with follow focus accessories. Also, focus, aperture, and depth of field markings are on the side of the lens to aid focus pullers who typically operate on the side of the camera. Aperture is measured in absolute T-stops to provide accurate and consistent exposure across lenses and color rendition is matched with other Rokinon cine lenses for consistency.

This fisheye lens provides a 180º diagonal angle of view on full-frame cameras for an ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes and creative experimentation in any application. The T3.1 maximum aperture is effective in low light situations and enables some measure of shallow depth of field control. 

The lens' optical design consists of 12 lens elements arranged in 8 groups including three elements made of low dispersion ED glass and two aspherical lens elements to minimize coma and chromatic aberrations. Highly effective nano crystal anti-reflection (NCS) coating applied together with UMC coatings improve light transmission and reduce ghosting. Its internal focus system does not extend the front elements during focus and minimizes the effects of lens breathing.

This Nikon F Mount manual focus lens optimized for digital cinema provides a de-clicked manual aperture for smooth and silent adjustment and unified focus and aperture gears for use with a traditional follow focus. Also, focus, aperture, and depth of field markings are on the side of the lens to aid focus pullers who typically operate on the side of the camera. Aperture is measured in absolute T-stops to provide accurate and consistent exposure across lenses and color rendition is matched with other Rokinon cine lenses for consistency.
An ultra wide-angle fisheye lens with a 12mm focal length on full-frame cameras and an 18mm equivalency when used on APS-C and Super 35mm format cameras. Its distorted perspective is useful for interiors, landscapes, group shots and many creative wide-angle applications.
Extra low dispersion and aspherical lens elements reduce aberrations for sharp, color-accurate imaging.
Nano crystal coating and ultra multi-coating on the lens elements improves light transmission and reduces ghosting and flare.
Sturdy metal barrel with removable petal-shaped lens hood.

98% cotton comfort
Color: Black, Size: Large
It's true to size. I have a 42" chest and typically wear a large. I ordered large and it fits. Grab these while you can as most of these mock neck t shirts are a cotton poly blend. These are 98% cotton. This is important because although the cotton/poly blends dry quicker, they are uncomfortably warm if it gets above 70 F. I have purchased other mock turtlenecks and had my local dry cleaners convert them from long sleeves to short, but they are slightly heavier weight than these. I do wish that they made these in a dark green or military green color.

100% SYNTHETIC CONSTRUCTION!!!
Color: All White, Size: XX-Large, Color: All White, Size: XX-Large
When I bought this shirt, the listing claimed it was 95% cotton and 5% spandex... the shirt that arrived was 51% polyester, 43% viscose and 6% spandex! I have been impressed by some of their other clothing, but this is the first time I was completely lied to and bamboozled. I probably wouldn't have noticed if the shirt wasn't so hot, shiny, and uncomfortable! I will absolutely be returning this shirt. Not even CLOSE to what I wanted. Quite, quite disappointed.
