I am going on a wildlife/birding photography trip in a week. Right now I have canon's 70-300 f/4-5.6 IS USM and I just havnt got what I wanted out of it. I will mainly be shooting birds but also some wildlife. So here's the Qs...
#1 Should I keep lens and buy 400/5.6L+TC
or
#2 Should I sell lens and buy 100-400L (maby TC?).
or
#3 Should I sell lens and buy 300/4L+TC.
Those are my three lens choices and do not plan on going more exspensive than that. (Other brand suggestions welcome.)
Thanks,
BB


I think you can't go that wrong either way.
