Canon EF300mm f/2.8L lens in good working condition This lens has been used by a professional photographer and he/she has worn the paint off it from constant use but it works perfectly and it’s perfectly clean inside with no dust, fungus or scratches This is an old lens made in 1992 and quite heavy but the optics are fabulous Works flawlessly with the 1.4x and 2x extenders for 420mm f/4 and 600mm f/5.6 The current version of this lens is lighter and has IS but it costs $11,000 Look at some of the photos I’ve taken with this lens Works perfectly with every Canon eos camera and adapts perfectly on every Canon R mirrorless camera Only selling because I’m not using it much anymore and I want to buy more RF lenses https://www.kenrockwell.com/canon/lenses/300mm-f28.htm
