| Re: Canon lens age code here Yes, there were three versions of the 300/2.8L...the Series 1 and 2 were non-IS. The current series 3 is the IS version. I have a used, but very clean series 1 with the non-removable tripod foot, and it still performs flawlessly and gives me superb images. White Balance so easy, even our 5 year old can do it.- Melissa Strickland |
