Hey guys, I'm needing some extra reach and having a tough time making a decision between getting a Canon 400 f/5.6 or getting the Canon 300 f/4.0 and adding it to the Canon 1.4x III that I already have.
The 300 f/4 and 400 f/5.6 are pretty similar in size, shape, weight and price so I'm torn between the two.
I've tried the 100-400 in the past and just wasn't impressed so that's off the table for now.
Obviously the 300 f/4 would allow me to use it "as-is" and keep the f/4 when the situation dictates it and the 300 f/4 + the 1.4x III would put me at 420mm and still keep the IS so I think that's the direction that I am leaning but just wanted any additional input from someone that's had the same dilemma.
Am I overlooking anything? Still pretty new to photography so any input is welcomed.
This would be on my 7D and would be for a variety of subjects (birds, airplanes, autos, sports, etc) in well lit conditions typically.
