Off Axis Guider for Canon
The most stable OAG we know of, with tilting function and 10.8mm light path, optimized for M48 flattener, including T2 platform for MGEN guide-camera.
World first: OAG with tilting function for Canon EOS DSLR
The LACERTA OAG for M48/Canon combination has another function: It can be tipped by 3 side screws in each direction about 0.2mm. Thus, production engineered tilting (especially ocular tilting, reducer tilting, sensor tilting in DSLR) can be corrected. To adjust the tilt, the OAG does not have to be removed.
Optimized for M48 Flattener
The Guide-Prisma was fixed to counteract the many “OAG diseases ” such as adjusting guideprisma, or reflections or diffraction symptoms occurring by the light. Two versions are offered with a smaller or a larger prism. The position of the prism allows for full format cameras up to f/4 (version “S “-short), or up to f/7.3 (version “L “-long “-long) or slow tubes to be able to work without vignetting. Please provide this information (S or L) when ordering.
Geometry may require shortening the original M48 flattener thread in certain cases. Too long or too wide M48 threads can collide with the guide-prism when screwing in or cover the flow of light to the guide-finger.
