the endless search for a decent cheap 300mm lens is over. Once you've got a Canon 400mm L lens, it's hard to "mute" it, so to speak. All I want is a sharp image at 300mm and not that sharp, 8 out of 10 sharpness is fine. I now have a total of 4 Canon 70 300mm lenses, all used but in very good condition. they were soft at 300 a piece so they were sold shortly after they arrived. my camera is canon t3i. Here are the lightweight, compact pros. The focus is satisfactory and the images are clearโฆ
