Sport photography is a combination of both imho. Both human skill and the aid of the gears play their important parts. Different sport photography have different set of requirements though.

But did you notice in your pics, that the lens focus was hyperfocal? Everything from the foreground to infinity is in focus because of your aperture setting. So is it really much of a strain on the autofocus when your depth of field is infinity?

Indeed!and we've seen shots from point and shoot camera's for a very long time. And so I think there is a great deal of arguing based on a proper understanding of the term "Sports Photography". Which I also think can be likened to general photography, where everyone's a photographer until they actually become a photographer.

The lens is normally wide open when focusing, so how does aperture affect autofocus performance?

Not to be a smart a__, but that is a common reply when this topic comes up. Somebody shows some really nice sports shots and says something like "Pentax Does Sports"

While that may be true, I have seen Canon guys do the same thing. Plus, are you saying that you can only shoot wide open for it to be sports photography?

Ok so I'll say "Photographers can do sports with Pentax"... LOL



I'll be the first to admit that Pentax's AF just ain't up to snuff, at least on the K10D/K20D... This shot shot using single frame mode (no burst crap for me), manual focus (preset at anticipated distance) with no hyperfocal intended, aperture at f13, 1/180 sec pan...

So I will say, IMHO.... skill, timing and luck...

20mm f13 actually, pretty hyperfocal.

If you are not happy with your Pantax gear, then go!
It is better for an unhappy pantax shooter to leave than to stay, a happy photographer is always better, regardless what gear he's shooting with…
But, don't forget, I stay and I know why.

I guess if you are happy just getting one shot, this works. I would like to have this shot, a head shot, a shot of the pedals with shin to see the muscles, a shot of the wheels with a nice blur, ..., but if you're happy with just this one shot ...

Thank you

Really irrelevant anyway. There was no intention to execute a hyperfocal situation. The focus point is precisely where I placed it and the aperture was solely a function of what was needed to prevent too high a shutter speed which would have prevented the panning blur.

Russell,

Even a pro shooter with a $6K Canon EOS-1Ds or Nikon D3s and another $20K worth of lenses will not get all of the shots you mentioned in a single 1/2 second pass. Each of those shots requires a different technique, shooter positioning and preparation. Tell ya what, I'm shooting another bike race this Sunday and I'll do my best to get the shots you desire... but if I don't it will be MY fault, not my gear's...

Mike

p.s. feel free to check out my motorsports and velosports galleries if you think I am happy with that one shot.

MRRiley. Very nice shot. Your efforts are appreciated. Unfortunately, no matter how good the shot, the Pentax bashers will find some reason, setting, or circumstance to support their positions. In my opinion, the Kx is a lot of camera for the money, the best bang for the buck on the planet. And by the way, Pentax does sports and a lot more. Kx, Tamron 18-250, full zoom, front page of the paper and a finalist in the California Newpaper Publishers Association yearly contest, Spot News category.

FYI - as the original reason I started this thread was the death of my SDM lenses...
Pentax Canada has sent me an estimate on the repair of the DA*50-135 in question - they are replacing the motor and/or/same? gear plate A assembly. Charging me for the parts only as a "goodwill gesture" (their words, not mine) because it was out of warranty by 6 months, and I had just had motor replaced on my 16-50 (plus an additional "repair" because it stopped AF after the motor was replaced)
Don't get me wrong, I think Pentax has wonderful glass. I have some incredible sports shots also, but it is slow to track, especially in arena's where I'm working at the 2.8.
I have learned to work around this by really getting to know the camera. My whole point of this thread, was that I was frustrated with high quality lenses breaking down far too early. When your gear is breaking down before it should, a person does question the brand they are using.

This thread should be so over by now. But I'll give in to the urge. I think it's 100 percent correct that Pentax needs a new f/2.8 telephoto lens in its lineup with a better and more reliable motor and the next camera could use better tracking-- I don't personally use tracking probably for this reason. This said, it is possible to use Pentax for sports, even if the current lens and camera lineup is not ideal for it. Ultimately, sports are hard to shoot period, which is part of what makes it fun to try.

A few examples of my Pentax sports shots:

K-7 with 50-200





K-7 with Tamron 70-200






K-x with DA* 16-50




(The one below is at ISO4000. Not too shabby IQ considering. I have a few this player dunking but I liked this one better)
