The Canon CN-E 14mm T3.1 L F Cinema Prime Lens EF Mountis an ultra wide-angle, manual focus prime lens that covers Full Frame and Super 35 sensor formats.

The lens offers a maximum T stop of 3.1 and has an 11-blade iris that provides round out of focus highlights for a natural looking bokeh. The lens barrel features 300° of stepless, smooth rotation from close focus to infinity, giving you a high degree of precision and consistent focus.

The lens is designed to minimize focus breathing and also has innovative glass construction that counteracts barrel expansion and contraction to avoid temperature-induced marking discrepancies. It has focus distance markings on both sides of the barrel, with the rear markings on an angled surface, making it readable from either side of the camera. It also has a dust and water resistant housing to minimize maintenance.

The CN-E 14mm and the other five CN-E lenses share the same 114m front barrel diameter, focus rotation, 36° iris rotation, and focus and iris gear positions, allowing for easier lens swaps.

Q: 3. Does this lens support 6k resolution? Can i put a circular ND filter & is there a 114mm circular ND filter?

Q: 6. Will this lens work on a Canon crop sensor 60D?

A: Yes. It will work on any full frame or aps-c canon camera.

Q: 7. What kind of horizontal distortion does this lens render on full frame around the top and bottom of the frame? Does it have barrel distortion, bulge distortion, pincushion distortion, or wave/ wiggle distortion? Do lines stay straight horizontally?

A: All extreme wide lenses exhibit some level of barrel, chromatic, and rectilinear distortion. If you wish to avoid these negatives while using wide lenses, do not get too close to your subject and cause barrel distortion or tilt and cause leaning lines. This Canon CN-E 14mm reduces all wide angle distortions to an absolute minimum. This is in keeping with the fact that this lens is meant for the Hollywood market where only the best will do. Final note: Wide and tele lenses have characteristics unique unto themselves. In the beginning of their camera career, people often look at these characteristics as negatives to be overcome. In time, the user knows what to look for and then exploits these characteristics to storytelling advantage.

Q: 8. If you had to choose one cinema lense for a short film with the C100 Mark II, is this lense a good option?

A: No, this is an ultra-wide lens and if you are shooting an entire film with one prime lens, a 35mm or 50mm would be much better. The Canon 24-105 L series zoom works perfectly with the C100 and can provide image stabilization and auto-focus as well as lens distortion correction in one compact package.

Q: 9. which one is better, this lens or Rokinon Xeen 16mm T2.6?
