Re: Continuous Autofocus w/ K20D and DA*
Nice shot Paul. The shallow depth of field works well here. Just curious, were you the center focus sensor or the full array?

Re: Continuous Autofocus w/ K20D and DA*
Even though a subject moving directly toward or away from the camera gives you the best chance at stopping the motion, this is still a nicely done terrific image. Subject's 'pose', beautifully caught!

Re: Continuous Autofocus w/ K20D and DA*
Thanks George. I never use the full array. I believe I was using the select function here and had chosen the sensor that is uppermost when shooting in a vertical or portrait mode. That's generally how I work when trying to shoot walkers in continuous focus mode. Paul On Mar 16, 2008, at 10:01 AM, George Sinos wrote: Nice shot Paul. The shallow depth of field works well here.

Re: Continuous Autofocus w/ K20D and DA*
Thanks Paul - Most of the time I only use a single sensor. It's probably my imagination, but I think the camera focuses faster when you only use one sensor. (Heavy emphasis on the imagination part.)

Re: Continuous Autofocus w/ K20D and DA*
I should point out that while a it's easiest to stop action when a subject is moving toward camera, it's the toughest job for continuous autofocus because the focal point changes rapidly. My DA 50-200 on the K10D is pretty hit and miss on this. This combination seems, at first look, to be much better. Paul On Mar 16, 2008, at 10:39 AM, Paul Stenquist wrote: Thanks Jack.

Re: Continuous Autofocus w/ K20D and DA*
Not your imagnation at all. That was my experience with most camera's I've used (the exceptions are manual focus or single-sensor only bodies). It has to do with processing power, more points means more processing. Even my D300 is faster in single point mode (or with the 9 point tracking option in single dynamic mode, 21 and 51 point are slower). -Adam On 3/16/08, George Sinos [EMAIL PROTECTED] wrote: Thanks Paul - Most of the time I only use a single sensor.

Re: Continuous Autofocus w/ K20D and DA*
Paul this seems to go in the same way as the (very unofficial) test posted at pentaxforums (K20D+DA200) which indeed point to a better AF-C performance than K10D. Now where is the better performance factor... SDM algorythms? K20D AF module? both? Good news anyway :) -- Thibault Massart aka Thibouille -- Photo: K10D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ...

Good to know someone else is seeing the same thing. I shot a few more walkers today with similarly positive results. Have to try it on some cars.
