The samyang XEEN 14mm, EF Mount is built specifically for use as a cinema
lens. It features an internal focus design so that the lens does not change
size while focusing, minimising the appearance of breathing when changing
focus. Each lens in the set is multi-coated for good contrast, glare
prevention, and colour-match to a factory standard, allowing you to assemble a
set over time with minimal colour shift. This 14mm lens affords what is
considered a very wide angle of view on full-frame cameras, and a tighter angle
of view on smaller formats.
