Why would someone want to buy a cine lens over a manual photography one? _________________ Nikkor 24mm f2.8 ai, Rokinon/Samyang 35mm f 1.4, Nikkor 55 f2.8 micro ais, Rokinon/Samyang 85mm f 1.4, Pentacon 135 "bokeh monster" f 2.8, Contax Zeiss 180 f 2.8 |

ONe answer could be: to shoot digital movies. Cine lenses usually have longer focus throw and better focusing ring quality than photographic lenses.
But I suspect that many here buy cine lenses because of price and because they like to re-discover old forgotten lenses. _________________ Orio, Administrator

I'm assuming (because of the forum section) that this is about purchase decisions for shooting films using DSLRs rather than choosing cine lenses for stills photography.
Cine lenses will have a number of feature out-of-the-box that make them suitable for video work that a manual lens may have to be adapted to provide:
- click-free, smooth action, continual aperture control
- smooth action, long-throw focus ring
- deep knurled focus ring compatible with follow-focus
- aperture scale measured in t-stops
Click-free aperture ring is probably the most significant, followed closely by the throw of the focus ring. It needs to be a reasonably long throw for the operator to make steady and controlled changes in focus. |

depends what cine/video system they were designed for and whether the back focus(mount register distance) is suitable for your camera.
Example. A D-mount cine lens - probably the smallest mount - is designed to cover an area of 4.8mm by 3.5mm so the image circle is very small. The mount register distance is 12.29mm. It is possible to use these lenses on a Pentax Q (sensor size 6.17mm x 4.55 mm and register distance of just 9.2mm) with perhaps a touch of vignetting. The lens goes slightly inside the mount.
C mount lenses come in different types and the image circle varies depending upon which sensor it was designed for and which camera you use. I get vignetting on my NEX with a TV lens, but on a M4/3 is is less visible due to the sensor size.
Larger lenses can be used, obviously lenses designed for 35mm will be perfect on crop sensor cameras. But are extremely expensive.
The resolution of cine lenses is outstanding this is why they are popular. And TV lenses are considerably smaller than their 35mm full frame counterparts. _________________ Hero in the 'messin-with-cameras-for-the-hell-of-it department'. Official. |
