This Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens is a great starter lens or a great additional for outdoor photography with it'z zoom capabilities. With a focal length of 75-300mm and a maximum aperture 5.6, this lens allows you to capture stunning images that could otherwise not be captured without these features. The lens is compatible with Canon EF mount and is both auto and manual focus. This lens is ideal for capturing distant subjects and the zoom feature allows you to adjust the focal length depending on the distance of your subject. I bought this new, it has been used, but for a short period of time. I haven't used it in years since I had a canon ti. I am not able to test it due to not owning a canon camera anymore. It has been sitting in a closet since the last I used it and it worked great!
