I can't comment on the Kx, however I do have the K7 and like you do shoot football under what is laughingly referred to as floodlights. The K7 is fantastic in comparison to the K10d. I can take photos of the action under floodlights that are very useable.

See this set.

Will,

I hope you are enjoying the K7. It is an awesome bit of kit. Hardly touch my K10d now. However keeping it as a back up & to shoot remotely behind the goal at football.

with regards to the white balance on the K7 I often shoot football in lighting that can change from quite bright to floodlit over the course of the game. just leaving the K7 on auto white balance copes with it very well.

I use ACDSee Pro 3. awesome piece of software.

Awesome lens. Since I got it I use it far more than any other. It's just a shame that AF is so slow. Though using AFS is not too bad AFC is woeful.

I'd love to try that lens out.

I can't ever see me buying one though. That is a whole heap of wonga!

This was a while ago. Pentax have outsourced the repairs since then. Here's my post on the subject.

I've been using 2.5 and for some time the Beta version 3.

It is an awesome programme.

Shame there is currently an issue with the K7 and DNG files. But I'm sure it'll be sorted out soon.

OK I have one for you. Shortly after I got my K10d I was taking some photographs of my 2 kids and there friend just mucking about in the living room. Anyway My daughter who would have been about 9 months at the time. climbed up on the the arm of the chair and started to lean back on the door. I took a photo because I thought it was cute.

However the afore mentioned door started to move and my daughter started to fall backwards onto the ground. Being the oncerned dad that I am I think I tried to get a photo before dropping the camera onto the sofa and catching my daughter.

Unfortunately, not being superman, I didn't get the pic, my daughter hit the ground, (she was ok) and the K10d bounced off the sofa onto the ground breaking the LCD screen!

Later the camera got sent back for repair and came back from Pentax after being butchered, but that's another story.

I have certainly found that the AF on the K7 is much quicker than the K10d for the DA*60-250.

Next football match I'm going to put the Bigma on the K7 and see how that compares.

I have found that the AF on the K7 is excellent in low lighting, under floodlights last week I got some useable shots whereas with the K10d I wouldn't have.

Taken with the DA*60-250 lens.

K10d under the same conditions doesn't get any usable pictures at all. I'm very happy with the amount of noise that doesn't show up at 1600ISO.

There was loads of potentially good photos I missed last season under floodlights. Hopefully I'll get a few more this season.

Thanks hefty1, I certainly couldn't have managed without the K7.

Oh and the camera was faithfully auto-focusing all match. I used AFS as it is a bit quicker than AFC but it works. woohoo.
