The Ultimate Bundle from Letus35 is designed for the serious professional who needs a versatile adapter suitable for use in television and film studios. It contains the Ultimate Depth of Field Adapter with an optimized achromatic lens and a 72mm Camera Thread Ring, a PL Lens Mount, the Support Rod System Version 2, and a Custom Case. It is suitable for use with Letus Relay Lenses.
The Ultimate Depth of Field Adapter is a 35mm adapter. Its spinning glass design allows for wider f-stops and slower shutter speeds. Features IOC prism technology allows the image to be flipped upright, so there is no need for flipping the video later or rigging special preview monitors. The IOC prism not only flips the image, but also provides a longer optical path between the camera sensor and the ground glass. This allows the adapter to obtain a much sharper image in a shorter body.
The 72mm Camera Thread Ring helps connect the Ultimate Adapter to the camera.
The Support Rod System Version 2 is a standard 15mm system that works with all Letus35 adapters. It comes with an L-Rise, so you can step your adapter up or down from the level of the camera. It also includes a front support bracket with a large cradle. It is CNC milled from solid aluminum and hard anodized in black and blue.
The Custom Case is specially designed to store the contents of the bundle.
