If you want to invest in the best gear you can, than this is the Letus 2/3" B4 Pro Relay
Letus B4 Pro Relay
The Letus relay lenses allow you to bypass the stock lens of your removable lens camera entirely. This offers many advantages. Since the relay lenses are purpose built, they are going to provide the sharpest, most light efficient image possible. The lenses are also smaller then most stock lenses making for a more compact 35mm adapter camera setup. With straight forward controls for aperture and focus (both lockable), there is no complex setup routine necessary when using a relay. If you have a removable lens camera, then a Letus relay lens is certainly the best option for top quality 35mm footage.
The 2/3" Pro Relay is a Letus Relay Lens Module for B4 mount cameras, 3/4 stop brighter than the P+S PRO35 relay. This relay lens will allow you to attach a Letus35 Extreme, Elite, or Ultimate adapter directly to the camera body bypassing the stock lens entirely. Precision calibrated to the Letus35 adapters (Extreme, Elite, and Ultimate) and designed for use on 2/3" B4 mount camera systems. We cannot guarantee compatibility with other 35mm adapters.

Letus LWS Rods
Letus light weight support rod system (LWS) for ENG style cameras. Use this compact, light weight system for supporting your Letus adapter, relay lens, ENG lens, mattebox, follow focus or accessories on an ENG style camera.
The LWS system is an extremely compact and light support rod solution for large cameras on which you need to attach a 35mm adapter (or any other 15mm rod accessory). The LWS works best when using a relay lens with your adapter as it significantly shortens the length of the lens setup.
We also offer telescoping support rods, part of our Raptor system, that are compatible with the LWS rods. The telescoping rods allow you to extend and collapse the support rods to accommodate various length needs without having to switch the support rods out. They work very well with matte boxes especially.
The L-bracket and front piece of the LWS system is also compatible with the Raptor Light Camera Plate. This allows you to utilize the front of the LWS on the Raptor system. The parts are easily interchangeable if you need to mix and match different systems on different cameras.
Mount your Letus adapter in "snorkel up" or "snorkel down" mode
Use with Letus relay lenses / adapters or standard ENG lenses
Great for matte boxes and follow focus systems
Eliminates the need for a L-Riser
CNC milled, high-grade stainless steel (SS) and aluminum
Contains IOC prism technology which means the image is flipped upright, there is no need for flipping the video in post, or rigging special preview monitors.
Our IOC prism is not only for flipping the image, it also provides a longer optical path between the camera sensor and ground glass. This allows us to obtain a much sharper image in a shorter adapter body. Please visit our Wiki for more information.
Our modular design allows a single adapter to be used with many types of lenses and cameras. You do not need to purchase a adapter for each camera that you plan to use. Please visit our Wiki for more information.
The Optimized achromat is a special lens in the back of the adapter that resolves the issue with Edge to Edge focus on cameras that have offset image sensors such as the: Sony PMW-EX1/EX3 and the Panasonic AG-HVX200/HPX170. Please visit our Wiki for more information.
The back focus ring is a feature that allows you to easily adjust back focus without needing to manually adjust the ground glass position. You simply loosen the locking screws and adjust the ring until back focus is correct. Please visit our Wiki for more information.
