I've had mine focus and then wouldn't take the shot a number of times. Very random. I've sent mine in for repair/service....

Never had it go off with the movement of the camera. Do you have a grip on it? could the button on the grip have triggered the camera?

Excellent. Love the water droplet on her head...

Superb, just superb. Excellent shot.

I agree totally. Many times in the past I had a camera change mode without noticing, never again.

Mine three...

Welcome. Enjoy your new camera. I'm sure you will...

...and charge the battery.

Welcome and enjoy your new K5...

The card I mainly had issues with was a Sandisk ultra (2gb from memory)

Hope you get to the bottom of the issue soon.

Pianoman & Puma, can I ask what type of memory cards are you using? I had a similar issue with a K20D and also a K7. The cameras locked up whilst shooting, quite often in burst mode and similar to you chaps I had to remove the battery to reset the camera.

If I looked at the memory card afterwards there would be a blank corrupted file which hadn't saved properly.

I returned my K20D and we couldn't replicate the issues in the shop, however I hadn't reformated the memory card which had been in the camera so I could show the shop assistant.

I put two and two together (and came up with seven but that't neither here nor there) and put it down to a corrupt/slow memory card.

So I purchased some quicker named-brand memory cards and (touch wood) I haven't had a similar problem or a problem with my K5.

Hope this helps

What focal length were you at? Still very envious....
