As I mentioned in another recent post, I was on a trip very recently that showed me some weaknesses in my kit. I have a 7D and 100-400, among other things.
There was some serious enthusiasts on the trip I was on, with kits in the $25k to $30k. I am not even considering going to that extreme, but I do need to make some decisions. they got some gorgeous pictures with 1DXs and 5D Mark IIIs, using 300 2.8, 400 2.8, as well as 500 4.0 and 600 4.0 (throw in some 1.4x and 2.0x to complete the picture).
I am reevaluating full frame sensors vs my 7D's 1.6 crop factor. As I shoot about 70% wildlife, I am loath to give up the extra reach of the 7D, but ISO above 1600 leaves something to be desired (I ended up shooting a lot at 2500 and 3200, and even some at 4000 and 5000 (threw most away though)). If I switch to full frame, then I would think I need to go with a 300 2.8 or 400 2.8 and a 1.4x and 2.0x teleconverters (500s and 600s are out of my price and weight range).
I would like to hear people's thoughts on these two lenses with and without teleconverters. Which is more important, the version of the lens or the version of the teleconverter used with it?
The lens would have to be used, and am prepared to be very patient waiting for a reasonable deal. Where would you recommend watching for sales of used lenses of this nature?
