Re: Nikon v Canon 500mm? AF and fpsI suspect you aren't just limited by autofocus, but by frame rate. A high
frame rate is essential to get the peak of the action, whether for sports or
wildlife. I use a Canon 600 f/4 L IS on a Canon EOS 1v, sometimes with a
1.4x or even 2x (AF is maintained). (BTW, this camera uses a bit of
celluloid inside it, which reacts to the light. It is then sloshed through
some nasty chemicals, revealing a picture. Some of you old-timers may
remember it: It's called "film").
I've been watching the digital revolution from afar, waiting for the time
when a camera (I only consider Canon, because I have all the lenses) would
actually be good enough. I think that time has finally come, with the Canon
Mark III. It's the first digital that has a frame rate that I consider
sufficient for wildlife: 9-10 frames per second (depending on focus
setting), just like my 1v. The peak of action may only last 0.1 sec., so
shooting at 3-4 fps will likely miss it. You still might get a nice shot,
but, for example, the eagle's mouth will only be open a sliver, as opposed
to all the way in a dramatic moment.
Of course, AF tracking isn't always perfect, especially with teleconverters.
That's where technique comes in, being able to maintain view of the subject.
I use a Wimberly head, which is needed for a 13-bound lens. I also use a
Canon 100-400 f/4.5-5.6 L IS, but images are not as sharp as with the 600.
