Default I need advice on a Pentax Kx -- about to purchase

I have researched several cameras and will probably buy a Kx soon. I am unable to purchase from a camera store and will buy online, so I am relying on reviews and those who have firsthand experience.

One point that came up in all reviews was that the Kx sometimes had problems with its AF system in that it failed to "grab" the subject.

For those of you who use the Kx and use the auto mode, how often does this issue arise? My old P & S that has died had these symptoms, and it was not pleasant - I like to hear click when I push buttons.

If this is a problem that only happens once in a blue moon, I will sacrifice for the affordability and for the size of the camera.

Thanks for the help.

Hiya. Regarding Autofocus, the K-x AF is: Full Autofocus 0.097 sec.

From http://www.imaging-resource.com/PRODS/KX/KXA.HTM
"Autofocus. The Pentax K-x uses an 11-point SAFOX VIII phase detection autofocus sensor, which offers nine cross-type points. The same sensor has featured in quite a few of the company's digital SLRs since it launched in 2003's *ist D, Pentax's first digital SLR. Indeed, the flagship K-7 still uses a similar sensor, although it supplements it with a dedicated AF assist lamp and a secondary light color sensor, as well as refined AF algorithms. It's a significant upgrade from the five-area AF system of the K2000. As we mentioned, though, there are no AF in-focus indicators in the optical viewfinder to show which AF point or points are selected."

"Responsive 11 point wide angle SAFOX VIII autofocus system focuses quickly and accurately, and can easily track moving subjects."

Hope this helps. I don't think you will be disappointed with the K-x concerning autofocus.

In low light the the k-x is the better system. That seems to be the concern of the op.

I agree... sometimes reviews say things about ALL cameras that can put you off... bock1965 is right, don't be overly worried about reviews... By the way, Amazon has good service... I do business with them in (they are located in Bristol, England), and they treat me like I am royalty... Luke, you will be happy with your purchase. Just get to know your camera... take things slowly... just enjoy. Ned
