Introducing a B4 lens to a modern cinema digital camera is not a very simple job. B4 lenses are intended for more compact 2/3 chip sensors, and to get the most coverage, some kind of lens is normally essential at the rear of or inside the mount. This option is not made for all cameras. It is exclusively for the Red V-RAPTOR and KOMODO.
Digital Glue has worked with Breakthrough Images to produce a B4 to RF mount. They point out that this is the 1st experienced B4 to RF mount for the Crimson V-RAPTOR and KOMODO. This is a basic mechanical mount that makes it possible for owners of B4 2/3″ lenses to use them with the KOMODO at Hd 120fps or UHD 60fps with the designed-in doubler engaged. If you have a V-RAPTOR you can use a B4 lens to record High definition and up to 240fps and UHD up to 120fps with the doubler engaged. As the Crimson cameras can do a center crop on the sensor, they will perform with a large array of B4 lenses. Center crop manner successfully lets the digital camera to use these lenses that are intended for much scaled-down sensors. There are no optics inside of the B4 to RF mount.
Adapters like these are really area of interest products and there are not heading to be a ton of folks putting a 2/3″ B4 lens on a Pink. Certainly, you could use a B4 lens in a are living ecosystem or broadcast situation, but that is also correct of any lens. What you also have to recall is that this is a mechanical adapter so it is not heading to energy a B4 lens and give you servo zoom capabilities. You would have to have to use an further option to be ready to electric power the lens. Yes, you could just use the guide zoom ring, but then that type of defeats the intent of seeking to use a servo zoom lens in the initial put.
It is vital to fully grasp that a modern 2/3″ B4 lens will do the job the very best. Older B4 lenses that are not built for a single sensor will not give you the high-quality you will want. You will typically also find that when making use of more mature 2/3″ lenses that had been built for use on CCD sensors that you will get pretty poor chromatic aberration on a modern-day sensor.
The Electronic Glue & Breakthrough Photography B4 to RF mount will be shown at the Digital Glue at NAB booth C4442 with a thoroughly kitted RAPTOR.
