Including a B4 lens to a contemporary cinema digital camera just isn’t a easy process. B4 lenses are designed for smaller 2/3 chip sensors, and to get probably the most protection, some form of lens is often wanted behind or contained in the mount. This answer just isn’t designed for all cameras. It’s particularly for the RED V-RAPTOR and KOMODO.
Digital Glue has labored with Breakthrough Images to develop a B4 to RF mount. They state that that is the primary skilled B4 to RF mount for the RED V-RAPTOR and KOMODO. This can be a easy mechanical mount that permits house owners of B4 2/3″ lenses to make use of them with the KOMODO at HD 120fps or UHD 60fps with the built-in doubler engaged. If in case you have a V-RAPTOR you should use a B4 lens to report HD and as much as 240fps and UHD as much as 120fps with the doubler engaged. Because the RED cameras can do a middle crop on the sensor, they’ll work with a wide range of B4 lenses. Heart crop mode successfully permits the digital camera to make use of these lenses which might be designed for a lot smaller sensors. There are not any optics contained in the B4 to RF mount.
Adapters like these are fairly area of interest merchandise and there should not going to be a ton of individuals placing a 2/3″ B4 lens on a RED. Sure, you might use a B4 lens in a dwell surroundings or broadcast state of affairs, however that can be true of any lens. What you even have to recollect is that this can be a mechanical adapter so it isn’t going to energy a B4 lens and offer you servo zoom capabilities. You would want to make use of a further answer to have the ability to energy the lens. Sure, you might simply use the guide zoom ring, however then that form of defeats the aim of wanting to make use of a servo zoom lens within the first place.
It’s necessary to grasp {that a} trendy 2/3″ B4 lens will work the most effective. Older B4 lenses that aren’t designed for a single sensor is not going to provide the high quality you will have. You’ll typically additionally discover that when utilizing older 2/3″ lenses that have been designed to be used on CCD sensors that you’re going to get fairly dangerous chromatic aberration on a modern-day sensor.
The Digital Glue & Breakthrough Images B4 to RF mount will probably be displayed on the Digital Glue at NAB sales space C4442 with a completely kitted RAPTOR.
