Focus Optics completely rehoused the optics of the highly-regarded Nikkor 14-24mm zoom lens into an all-new design. All new mechanical elements reverse the direction of focus to standard cine style. The focus rotation is extended to 126 degrees with an anti-backlash mechanism for repeatable accuracy. There are 14 focus witness marks (1’, 1’2”, 1’4”, 1’8”, 1’10”, 2’, 2’6”, 3’, 4’, 5’, 8’, 10’ and infinity). M.O.D. is one foot. For use of the lens when shooting VistaVision, a replacement screw-in front housing ring is included as the standard ring will vignette the frame on the widest focal length.

The zoom mechanism uses a unique dual-bearing race design to eliminate image shift. T-stop range is from T2.8 - 22.

The front diameter of the Ruby 14-24 is 110mm, and the lens accepts a screw-in 102mm filter.

The lens's overall length is 138mm, with a weight of 3 lbs.

The demand for 35PL lenses has never been greater, and most manufacturers have entered the market with sets of prime lenses, usually ranging from 18mm to 100mm and more. Focus Optics decided to fill the hole in the market with the Ruby 14-24 T2.8 Zoom Lens. The Ruby is based on Nikon glass, but the housing and mechanics have been completely reworked. The lens focuses in the standard direction that all PLs focus, with many clear focus marks on the large barrel. The whole lens is quite compact – only 138mm long and just three pounds. Focus, zoom and iris rings are all geared to cine standards, and the front diameter is a 110mm cine standard as well. The lens will also accept a 102mm screw-in filter on the front.
