K20d focus issue.
did pentax put the adjustment option on the camera as they knew something was wrong No. Every camera can have focus issus - not just Pentax. Ned Bunnell had some interesting things to say about it... the K20D is one of a very few cameras that allows the user to adjust focus. All the rest you send t...

K20d focus issue.
So when you adjust the focus setting are you adjusting the position of the sensor, or the setting of the AF system? If the latter, then manual focus should always be spot on and would offer a double check as to whether the system or the technique was out.

sometimes are past the finishline If your trigger device works when the horses are crossing the line it could be as much as 100ms (milliseconds) later that the camera shutter actually fires. In this time, fast moving horses will have moved past the trigger point. I would suggest moving the trigge...

Is the camera set to manual focus? If it's set on autofocus, it may take a split second to confirm that it is focused before the shot is taken. Just a thought. Dan

Do you have auto focus turned on? Just a thought, but is the camera trying to focus again, then take the shot? Wasn't there a guy in the late 19th century who first recorded how horses ran? I believe he had a string of cameras, triggered by the horse breaking a cotton line. But, he had it set u...

The speed those horses are going I doubt it would be able to auto focus :?: This kind of set up and calibration is best left to the pros I would think. Perhaps the K200 is not up to it and doesn't have the accuracy and consistency required for this sort of application. I have never seen a p...

If the camera is set to totally manual operation and is not in power save (turned off) mode at the time it is triggered, the results should be consistent. You'll need to set manual focus, manual shutter, manual aperture, and make sure the camera is on at the time the horses cross the finish line....

The speed those horses are going I doubt it would be able to auto focus :?: Well, probably not, but I was (we were, Ted was a little slower than me ;-)) just suggesting a possible solution. It could be that the OP has a manual focus lens on, but has the camera set to AF and it needs the confirmatio...

Yes the camera is set to manual focus on the on/off under the lens. And the string line across the track I have done it before is just a string line wich on the side where the camera is place has a micro switch that sends the signal to the camera acting as a cable shutter release when the horses ...

Yes the lens has an auto focus. How I turn off the one from the camera? The laser is at 39 inches right on the bottom of the neck of the forse ant on top of the legs, so triggers same because the movement of nose goes with it same distance.

Yes the lens has an auto focus. How I turn off the one from the camera? There is a switch on the camera body, looking from the front, it's bottom right of the lens mount, and this should be set to 'MF'. Dan
