Tele lens with ultimate optical resolution.
Add to compare

90FL model was keeping the top rank among high-end BORG tele lens line-up until 107FL model was released. The reason for that is in unexceptional optical resolution achieved by adopting fluorite glass element from Canon Optron in the optical design of the objective lens while featuring super tele 500mm focal length and aperture f/5.6. Great gear for shooting wild birds. In spite of the large front element diameter of 100mm the model is extremely compact and lightweight thanks to carbon fiber made barrels that makes it easy to carry on the location. It is also possible to convert tele lens to telescope by removing the camera mount and attaching prism and the eyepiece instead.
