Hi All,
I'm interested in Baader Hyperion's to use for projection photography with my Canon EOS camera along with my t adapter and get an M43 to T adapter. After playing with the
http://astronomy.tools/ FOV calculator i was curious. With the following, would the images be projected into the centre of the sensor like a camera lens with heavy vignetting depending on exit pupil or are all focal lengths projected out at 72 or 68deg which should cover the sensor.
