• 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.

Now that I have the 500L and 300L, I need to do some AFMA. Never did this before as I found the focus of my other lenses were on point, but want to make sure my new toys are good to go.

Should I go out and start using it before doing AFMA? Or is it generally accepted that AFMA must happen before using these longer tele lenses? Also, any tips? FoCal Standard, Plus, or Pro?
