• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Anyone have any experience with the Sigma 300mm f2.8 prime? I'd be interested to hear any and all experience but particularly that of anyone who has also used the Canon 300's (Non IS, IS I and IS II)
