Is a 300mm @21mp same as a 600mm@10mp?

Get a teleconverter

Get yourself a teleconverter. Say you use the two times, you loose about 2 stops of light (if I am not mistaken), making your 2.8 lens a 5.6 (check my counting am not mistaken). You now have a 600mm f/5.6 lens, taking a 20+ MP picture. And for what about $180 if memory serves me.

Plus, now you get the best of both worlds, and could drop a little more if you like. And lets face it, if you are birding, that two stops of light probably will not make as large a difference as if you were shooting indoors.
