I am considering the above combo for birding photography.
Currently, I am using 300f/4L + 1.4TC and may not know when will an upgrade urge is knocking;(, but as of now what are all users and ex-users or potential users opinion about this combo.
Would it be better to buy on-line from Wimberley, Naturephotographer.net or others on-line purchase or from local agent?
What will be the limitation of Side-kick? Weight leimits etc?
