Originally posted by Silverkarn I see a couple problems with the Original Posters topic.
1. Wording, i cannot tell from the first post whether the OP is holding the button down all the way thinking the AF works that way or not, better wording for describing the problem would be nice.
2. Not enough information was given. Was the OP using the LCD or the Viewfinder? What setting was the dial on? Fresh set of batteries? ect....
I do not own a K-x, but these 2 things still make a big impact on how others can help solve a problem.
No point in arguing anymore about this. The OP has not replied back, so they either solved the problem, returned the camera, or is an obvious troll.
Unless they are so busy that they just havent been able to check the forum again.
That was the crux of the issue with not doing a little research before going to the forum. It is great that we have so many people all over the world willing to help, but it ends up just being a waste of time for all involved (including the OP) if one does not even know enough to ask a good question.
I've often wondered why our forum does not have an area clearly labeled "FAQ." I suppose the articles are meant to perform this function. The generic list of things which can cause a DSLR not to lock focus or its shutter not to release could be listed in a FAQ section. These are pretty common issues, and not specific to Pentax.
