Here's a shot of the hummingbird I got. this was shot from less than three meters. Since it came to the feeder it was just a waiting game. Like everything it's a learning curve. first thought was focusing on the feeder but DOF issues didn't allow for that. I settle on Tav mode with iso I think as high as 3200 for some of the shots. Shutter speed up above 1/1000th, F13. I eventually went to single point focus with Continuous AFS, Back button focus so I could control it. Problem with the 300mm is if I missed the bird I would lose the lens to focus hunting as it search for the trees behind the bird, so used light focus burst I guess in combination with firing the shutter.
One thing I have noticed, even shooting in JPEG is the buffer and card writing time. If I fire off 5 to 7 consecutive shots it will lock up the whole camera, I can see the light going crazy as it processes them and tries to write them to the card, sometimes it gets so bad the camera freezes and I have to power it off. Not sure why this is happening.
k50 Jpeg High Burst rate with a 30mb/s SD card never gave me any problem
k70 Jpeg/or Raw high burst rate with 80mb/s SD card almost locks up the camera and sometimes freezes it. Is 80mb/s even for Jpeg on the k70 too slow?
A feature I read that sounds like it would be amazing for birds especially if you are afraid to lose them to focus hunting with a controlled environment like a feeder is the Sigma focus distance you can manually set to close and far limits to keep your lens close to where it needs to be. Must be nice feature if you have the money for the lens.
Anyways here's the shot I like, it will link you to the Flickr folder with some other Canadian animal life I got at the Cottage. the ducks were shot from shore at pretty close distances, They were pretty friendly and I just wait for one male to chase another male away and would grab them in flight. Enjoy
