Lens mounted mini teleprompter

This is a small lens mounted teleprompter, that uses a small tablet or large phone for running the script and a sample teleprompter mirror to do the splitting of light and providing a clear image. It's designed around the 6"x6" sample mirrors sold at https://telepromptermirror.com/sample/, specifically the 3mm thick version in either the 30R/70T or 40R/60T variation. The teleprompter attaches in place of the lens hood and uses the same mechanism and there are two different versions:One for Canon 24-105 F4 lensOne for Nikon 24-70 F2.8 (HB-40)There might be other lenses that share the same mount, but I have only tested with the two lenses above. As the glass is relatively small, both of the above lenses will need to be zoomed in to around 35-40mm, as otherwise part of the teleprompter will be visible in the picture frame. The Canon lens have the mounting point on the part that moves while zooming and hence does not protrude into the teleprompter, but the Nikon lens have it sl
