I have a deal on a 600mm 4L Is for around 5000.00 in suppose to be in mint condition. I have a pretty complete L lens collection, but not a long lens for shooting at the Zoo etc. The biggest lens I have is the 70-200mm 2.8L IS II with a 2X. Planning in shooting some Eagles next month. I felt this was a pretty good deal and hard to pass up, my first choice was a 400mm 2.8L IS so it could be used for shooting some sports, which is not done that often.
Any input would help
Thank you in advance
