However when shooting modern negative film the difference is negligible. When using RX lenses with the H-16 camera, the effective shutter speed is back to 1/65 of a second. Light Loss: The RX lens is calibrated to pass 1/3 more light than the aperture markings on the barrel indicates.RX lenses aim to remove the two problems the prism causes. The second version was lenses made purely for use on Bolex Reflex cameras (H16 RX), which are designed to correct some very specific problems caused because there is a prism permanently in the light path always diverting 25% of the light inbound towards the lens to the viewfinder and the remaining 75% to the film. The first version (Non RX) was made for Non Reflex Bolex cameras but would work perfectly well on any other manufacturers cameras that didn't use a prism in its design. Bolex produced lenses in two different versions up to 50mm in focal length. To compensate for the light reduction, Bolex has determined that the effective shutter speed for the H-16 camera is 1/80 of a second rather than the standard 1/65 of a second. The quality of the light reaching the film is reduced by about 1/2 to 1/3 of an f-stop. The reflex prism deflects 20 - 25% of the light passing through the lens into the viewfinder system: only 75 – 80% of the light reaches the film plane. The Bolex H-16 viewfinder enables accurate focusing and framing, and allows you to estimate the depth of field. You are 100% financially responsible for repair and/or replacement in the event of damage or loss of the Bolex, as well as any other equipment checked out from Media Loan. DO NOT use excessive force or over tighten anything on the camera.Let the camera acclimate to the environment you are shooting in by letting it rest in the case with the case tabs opened but the lid closed for at least an hour. Drastic temperature changes can cause condensation to occur inside the camera. DO NOT subject the camera to extreme heat or cold.DO NOT subject the camera to severe impacts or prolonged vibrations.Although all have similar features, the controls vary slightly.Īlso available for use with the Bolex cameras are zoom lenses, prime lenses, and an intervalometer as well as other accessories.Ĭare must be taken when using a Bolex because they are expensive and very difficult to replace. Media Loan’sĚdvanced Production Services (APS) has a variety of Bolex H-16 cameras manufactured between 19. Camera features include single-frame filming, extended exposure, slow motion, backwind and a 133 ̊-145 ̊ angle variable shutter. The self-threading allows easy loading of daylight spools. The optical system permits through-the-lens viewing at all times. The Bolex H-16 Rex and H-16 SBM cameras are 16MM reflex cameras.
