Thank you for sharing this James.
Regarding the Canon 70-200 f2.8 L IS:
Would it be this version: http://www.amazon.com/Canon-70-200mm-2-8L-Telephoto-Cameras/dp/B00006I53X/ref=sr_1_2?ie=UTF8&qid=1416448062&sr=8-2&keywords=Canon+EF+70-200mm+f%2F2.8L+IS
or version 2? http://www.amazon.com/dp/B0033PRWSW/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=NJA4Q9UX75RF&coliid=I2LCLNBO5WJ1U7
How is the condition? Any scratches? How much use has it seen?
Thank you for your time.
