I was looking at adding a used long lens to my collection. I know there is a few good seller on our forum and are more trust worthy than ebay or Craigs List. My question is this I just pulled my bid on a 600mm, because I really wasn't sure if it was the lens for me, price was around $7200.00 and it was very clean. I also found a 5 yr clean 400mm 2.8L Is for around $6000.00.
I'd like to use the lens mainly for zoo shoots, nature etc, but would like to break into shooting some sports, high school football etc. I have a 2X Ext I use on my 70-200 2.8L so that would extend a 400mm to 800mm.
Any thoughts on what I maybe missing or what I should consider? Will a 5 yr old 400mm 2.8L work on a T2I and or 5D MX II without an issue?
Thank you so much in advance
