BORG 90FL Tele Lens Set CH (6490)
The 90FL model was the top rank, high-end BORG tele lens until the 107FL model was released. The 90FL has exceptional optical resolution, accomplished by apochromat fluorite glass elements from Canon Optron, Inc. built in the optical design of the objective lens, and a super tele 500mm focal length and aperture of f/5.6. A great piece of gear for shooting wild birds. The 90mm front element diameter does not hamper the 90FL's extreme compact and lightweight capabilities thanks to the detachable carbon fiber made barrel.
You can convert this tele lens to a telescope by attaching a BORG telescope prism and eyepiece (sold separately).
