Tele-Lentar 300mm f5.5 Telephoto Lens w/ T Mount for M42 Screw Mount -Clean-
Here's a nice metal bodied telephoto lens with a universal T mount. It comes with a mount for M42 screw mount. It would be an excellent telephoto for a classic M42 kit or adapted to mirrorless.
This lens has a preset aperture meaning you set the aperture with one ring and engage it with another.
It is in excellent condition with light wear and works perfectly. The glass is clean and scratch-free with no haze, fungus or other problems. The focus is smooth. There is a small amount of oil on the aperture blades but it does not impact their function, they open and close smoothly.
Caps and the tripod collar are included.
