Shooting 20D with Canon 400mm f/2.8L + Canon 1.4TC mounted on Bogen 2031 Tripod with Bogen 490RC4 Ball head.
Sounds like a secret recipe for some great Fajitas!! (just kiddi'n). I will eventually come to understand everything you just said soon. Great picture.
.. sounds like you may have had one of those legendary days behind the lens??
the one thing that I love about silhouettes is that you have that fast shutter speed to freeze the action with plenty DOF.

Given the circumstances you had, how do you think your 100-400 would have done compared to the 400 prime?
Also, when using the AI Servo, what were your thoughts in regards to tracking and maintaing focus? I have goofed off with the AI Servo, but nothing close to what you are doing.
Chris, first off thanks! Now if I had been shooting with the 100-400, I would have had to either tape the pins on the TC or not shoot with it. At 400mm the f stop is 5.6 and adding the TC would bring it to 7.84(but you probably know that, just an fyi for anyone else following along) and the camera only recognizes 8.0. That's the bonus of using a lens with an F stop low enough to allow you to put on the TC and still maintain AF. The 400 prime is just a tad faster to AF than the 100-400, so I don't think there would be a focus issue, but optically the prime is noticeably superior. Not that the 100-400 doesn't take sharp pics, its just the prime is even sharper. I think I would have also had to bump up the ISO with the 100-400, maybe to 800, so there may have been a bit more noise. I don't think I'd be dissappointed with the results from the 1-4 but just that much more pleased with the prime.
On the AI servo, typically when shooting birds in flight I'm always using the AI servo with only the center focus point. If I'm using a zoom, I'll be panned back a little and then zoom in on the subject to get more frame filled. It seems that if the background is empty, as in the sky, there is less of a problem tracking. If I'm following a subject where there are objects inbetween myself and the the subject I'll occasionally lose focus on the subject, but as long as I continue tracking it will focuus back to the subject pretty fast.
It's pretty much a learning process, but it sure is a fun one!
BTW, from what I've been learning lately, using the custom WB is a key to getting a more true color representation of what you are shooting. I'm thinking of getting one of those WB cards for certain shots.
You have a beautyful avatar. While I'm not in the same league for picture takeing as you (hope some day to be) I too changed my avatar. This is my attempt to doctor a picture of my S&W. Any help on what else I could do would be well taken.
