    I'm shooting on a 70D so it's a crop body. I'm looking to get a good prime+extender combo. Which would be the best route, the 400 f/5.6 and 1.4xTC or 300 f/4 and 2xTC combo?

    I would get the 400 5.6, but neither of those combos will AF on your 70d. F/8 AF is reserved for the 1D series cameras and 5d3.

    Dang it you are right, looks like the 300mm and 1.4x combo would be the only one to work and then I might as well just get the 400 because it's only giving me 20mm extra while being a lot slower

    You'd have one 420 5.6 and one 400 5.6. Never used the 300, so can't speak on the AF speed, but you'd be better off w/o TC IMO. Either one can do BIFs.

    The 400mm f/5.6 is great but no IS. The 300mm f/4 does have IS and performs well with the 1.4x tc. Of course, if you're looking at mostly doing flight stuff your shutter speeds are going to be fast enough to negate vibration.

    If you think you will be photographing small birds and insects consider that the 300mm focuses down to 4.9 ft. vs the 400mm that focuses down to only 11.5 ft.

    If you want to save money and get the best, look at a used 300 f2.8 with the new 2X III for a 600mm f 5.6 with IS combo. The lens is so sharp that the 2X does very little if any to degrade IQ.

    Thought about this option and recommending it, but figured it was out of the budget range giving the 2 he was asking about. But it would be hard to beat.

    I started thinking and might save and go a route similar to that. I really want to get into the world of long primes but I'm happy with my 100-400 right now enough to where I might just save up to get what I really want.
