Re: Wildlife Photography (and all its difficulties…)

Thanks to all for the recent posts - this is all really useful information.

And great photos, too, Falk! I wouldn't have appreciated how much effort will have gone into taking those before my little sortie.

150mm f2, in the post to you Falk

cheers

Doing BIFs with the 75-300mm I get twice as many keepers at 200mm than 300mm, as AF is faster and at max aperture more light is available. So it is best to concentrate initially on shorter focal lengths to hone your technique before going for a greater reach.

I couldn't agree more with you, David. If the lens is too powerful, it can be very difficult to keep a bird in flight both in frame AND in focus, regardless of the AF system. Of course, some of the new cameras with huge pixel counts and full-frame sensors do help rather - you can lose a lot of the frame and still have a sharp image!

If your thinking of E-M1 ...

Since the firmware 3.0 the CAF is reported by several experienced users to be at a vastly improved level of speed and accuracy in tracking at up to 10 fps.

And for shooting with old 4/3 lenses improved too:

Sounds very encouraging for future Olympus cameras.
Cheers,
