I really want to scratch this itch, but it can't happen right now. That doesn't mean that I can't find out what I should get.
I first got into photography because I wanted to take pictures of wildlife and birds. I still do. That's why I bought the 100-400mm. It's a great lens, but I'm thinking about also having a prime. I'm in the process of getting a 1.4x TC (this will become relevant later on in the post). My question is this, which lens would be the best for my shooting situations?
This is what I think that I know about these lenses. I may be completely wrong, but please, feel free to comment.
Pros: IS, wider aperture, better IQ? Becomes 420mm f/5.6 with 1.4x TC
Cons: Less reach, but a 1.4x TC would help that. Does IQ suffer much with the 1.4?
Pros: More reach. 560mm with 1.4x TC
Cons: Wider aperture, no AF with 1.4x TC
I may be missing a few things here. But I would like to see everyone's opinions. The prices are somewhat similar, so that can be left out, as well as the weight, since the 400mm weighs about 0.2 pounds more than the 300mm. Thanks in advance.
