Re: Hi All!
There were several different versions of 75 - 300 mm zoom, but they are all old models designed in the days of film cameras. All of the recent designs are 70 (not 75) to 300 mm and are better than the old ones, in particular with regard to autofocus, but also in terms of image quality. However, there are also several versions of these, the latest is the EF 70-300 mm f/4-5.6 IS II USM. You need to be very careful when buying used as you need to be sure of which model you are getting. Some 75 - 300 models can be found very cheaply, but they aren't nearly as good as the 70 - 300 versions.
