I love shooting sports, but I do not have the money for a 400/2.8. Currently, I have a 400/5.6, but I was wondering about doing the following:
200/1.8 with a 1.4x or 2.0x extender.
It's cheaper than a 300/2.8, gives me a wider open option and, because of its sharpness, I was thinking that the extenders wouldn't be a problem. Of course, being so sharp, I could also crop more heavily when subjects are not so close.
What do you think of this idea?
