I have a crop-frame Canon (T3i) and only 2 lenses; the lovely EF-S 17-55 f2.8, and an EF-S 55-250 which I lucked into as a give-away after said lens was the only surviving piece of equipment after a friend's camera bag got swiped.
Obviously I already have a native 1.6x distance multiplier due to the camera body.
My question is, would the 1.4x TC be a good purchase? Primarily, I'd think it'd be used to extend the 55-250. It is already magnified x 1.6 to essentially a 400mm telephoto. But if I add in a 1.4 TC, would I be able to get acceptable bird shots losing IQ and a stop or two?
I guess a TC could also give my 17-55 a wee bit of extra reach, but, hmmm.
Note: I am not terribly serious about the long distance shooting, so I kind of hate to buy an expensive telephoto. On the other hand, I hate to buy even the teleconverter if it is going to be unacceptably bad results.
