Does anyone have experience shooting the 300 f2.8 VR using a Nikon TC-20E or TC-20E II tele-converter? I’m saving for my first big (and expensive) lens, and am debating between the 300 2.8 VR and the 200-400 f4 VR. I currently only own zoom lenses, and particularly like the flexibility; but the selection of big Nikon lenses with VR is very limited. I like to shoot wildlife, mostly, and currently have the 80-400 VR. But I find the f5.6 very limiting for wildlife, as the most active time for the critters is early or late where the light is often lacking. I’ve read that the 300 2.8 VR with the 1.4 TC is really sharp . . . so that would give me a 420 f4 . . . and if the light is really bad, I can take off the TC and maybe get a shot, even though I’d forgo the reach. But I’d also like the ability to get out to 600mm with the 2x TC if it works well; or maybe 510mm w/1.7 TC. I have seen work Wade has done with the 200-400 w/TC, and the results are great; please understand, I think that’s a great lens too (it also helps that Wade is a GREAT photographer). I will only be able to afford (yeah, in my mind maybe) one lens in this class in the foreseeable future, so I need one that is great in low light, but can be made to get the reach with decent f-stop in a pinch. I wish Nikon would make a 500 f4 VR . . . when I’m out shooting wildlife, particularly in places like Yellowstone, the Canon 500 f4 IS USM is the most prevalent lens in the gallery, hands down.
