Boy this is going to take a lot of practice with manual focus. Does any one have a good suggestion for this. I shoot with a canon 6d and a 60d. Any ideas would be helpful.
Here are some pointers when starting out. All camera settings, not shooting techniques.
1) Use AI mode in auto focus.
2) Use one or 4 focus points in the center of the viewfinder. Turn the rest off.
3) Shoot in continuous mode, using short bursts.
4) Leave that teleconverter at home for now. (Besides, it will not work with AF on that lens/camera combination)
5) Turn IS (image stabilization) off. When continuous shooting using a long lens, IS will only slow the AF acquisition rate down.
6) Bump up the ISO to 1600 or higher.
7) Shoot at f/8.0 versus the fastest f-stop for your lens.
8) Shoot in Aperture Priority mode.
9) Shoot at 1/1000 second for most birds, but if they are fast and close, bump that up to 1/2000 or 1/4000th of a second. You may also need to bump up ISO as well depending on lighting.
It is always a balanced judicious compromise between ISO and shutter speed for quality images.
There are reasons for each of these nine suggestions and NOT EVERYONE WILL AGREE with each of them.
But you asked for a starting point, and this one will give you the best chance to get some decent shots quickly.
I look forward to seeing some of your early efforts posted here on UHH.
By Christmas time, you will be ready for that Gimbal and a quick disconnect plate. It will help with some shots, will reduce lens holding fatigue, and help track most birds more easily. By then you will know so much more about what you want and need. Gimbals are handy, but are probably used less than 40% of the time when I'm shooting BIF. But I'd never leave for a BIF opportunity without one!
