QSI 683 with BORG 55FL F3.6

Steve Cooper sent me his latest images taken by BORG 55FL F3.6 & QSI 683 camera.

I think these were the good reference of actual FOV with 200mm f.l. and four thirds sensor to someone who are looking for high quality wide-field images with a relatively small sensor. It’s almost same FOV with 400mm f.l. and full frame sensor.



Beautiful pictures, Steve!! Thanks for sharing with us.

I just arranged a new 55FL objective adapter to a machine shop today. Once it will be commercially available, I will prepare FTF-M57 package as well.


7026 – 25mm-long Series 80 tube allows to set in front of the adapter, as a hood.
