There is plenty of good, great, even amazing vintage lenses out there, but very few of them are zooms. In fact, a good chunk of them are just too big, too heavy and produce soft images, but not all of them. For example, the Sigma 35-70 that I’ve reviewed in 2020 is small, lightweight and sharp. Many of you have suggested me to check out Vivitar and Canon FD zooms, so when I had the chance to buy this guy, I didn’t turn it down. The Canon 100-300mm is made out of metal, it weights around 800g, it is 21cm long when focused to infinity and 22.3cm when fully extended, with a 58mm front thread. The iris has 8 blades, the aperture is clicked and it goes from f5.6 to f32 with half steps. When focusing, both the external barrel and the front element turn 210 degrees and minimum focusing distance is 2 meters. Flange distance for canon FD lenses is 42mm, so they can be easily adapted to mirrorless cameras.  (affiliate link) Sharpness wide open is good across the frame and that shouldn’
