Until I got the 300mm lens my 70-200 2.8 was the champ. I also used the 1.4 tc with it and it worked ok but the images were a liitle on the soft side.

So I just shot the last 3 LAX games - about 300 pics/game and this it what I'm getting

about 50% of the photos are razor sharp

about 35% seem to be in focus but soft as I would be using my 70-200 zoom w/ 1.4 TC

about 15% OOF or wrong focal point.

Would this be user error?? This starting to bug me :(

JMO, but if you are achieving razor sharpness on 50% of your efforts, then the other 50% is probably due to the usual things:
- Low Shutter Speed
- IS Not Locked Up
- Misfocus

The last game the SS was 3 to 5K IS seems to be on but how could I tell? things happen really fast.
Misfocus - me or the camera ?

Thanks

Just takes a little getting used to the extra weight and inertia, thats all. You'll end up with too many keepers in 6 months, and will actually delete shots that were previously "your best ever shots, man!!!"
Oh, and pics or it didn't happen...

Paul,

IS is useless with shutter speeds that fast. In fact, you are SLOWING down the autofocus by using it. This may be what you are experiencing. Try turing it off. I've shot soccer for a number of years and rarely found a circumstance that IS added to my percentage of keepers.

Best Regards,
Matt

I agree with MattS. It takes a second for the IS to spool up and at fast shutter speeds it does you no good whatsoever. I discovered this a few years ago on my 100-400. The AF was a little sluggish with IS on but almost instantaneous with it off. I always shut it off on my 300 f 2.8 when my shutter speeds are fast.

Thanks for Replys I will try shooting the next game with it tuned off. I still can't get over the IQ I'm getting with this lens - Maybe one of my best purchases yet. :D
