Originally posted by WalterGA Maybe you don't know quite as much about baseball, Lowell, as you obviously do about photography, so please bear with me. You apparently don't understand why a few fps can make a difference. I'm talking about experience, not hypothetical speculation. The point of shooting the batter isn't just to catch the ball at "just the right moment." It's also to catch the batter's form through his entire swing. If you don't understand how a few more fps would be of benefit for that purpose, then we're so far off the same page as to ever agree on some of the subjective values of sports photography. Of course, 10-15 fps would be better for some shots than 3-6.5. However, the discussion was primarily about the paltry 3 that my K20 offers, vs. the 6.5 that a Canon 40D offers, which was my alternative camera choice. Might have gone for the 50D.
There's no doubt in my mind that photography was invented and perfected in Canada; however, we Rebels to your South invented baseball!
As a matter of fact, I didn't start this thread to discuss the subjective opinions of fps, but, rather, to find out the mechanical or firmware reason that Pentax offers such an embarrassing fps.
It is not a question of knowing baseball, I think in that respect the specific sport we are discussing is not relevant. This issue has been discussed with every new body pentax releases, and every time it comes back to the same thing, anticipation and knowledge of the sport is what is necessary to get a single shot, FPS does not cut it, or for motion studies the selected equipment is wrong.
The ability to capture an ultra high speed sequence is only really done in "still" photography by the Casio EV bridge camera, which shoots up to 1000 FPS. THat will show you an entire swing nicely.
As for limitations in the camera itself, you passed right over my other responses, it is not a firmware limitation as much as hardware. Mechanical stress on shutter and mirror to move them faster, the ability to dampen things such as the mirror, or mechanical re-design to leave the mirror up, and aperture closed down in continuous shooting mode etc.
If you want to do high speed motion studies then I think you are using the wrong tool. it is that simple
