I have gone back and forth between the 100-400L and the Bigma. At first I was thinking I might need IS but will probably be shooting outdoor sports of my children with a monopod. If I shoot wildlife, I will probably be on a tripod. I would like to save the money and get more reach if needed.
Have you tried the Bigma with a 1.4x?
Yes
MF only with the Kenko Pro and Sigma 1.4's I used, which would be fine other than the viewfinders on these DSLR's tend to suck. They're too dark unless you have a very fast lens. Stick my 85mm 2.0 or 50mm 1.4 on and it's like an African Summer has arrived. Stick a Bigma and a TCon on and it's like living in Finland
Wasn't to my standards IQ wise and either was the 100-400 IS L, but in IDEAL conditions then I imagine you'd get a result. I've also tried 2.0x Kenko Pro and Sigma on both and both sucked.
