The K-x takes 4 AAs, the K-r takes a proprietary Li-on battery with but you can get an optional AA battery holder. The K-r has illuminated AF points which the K-x lacks, and is fractionally larger and squarer, like a mini K-5. These are the main differences I think... oh, the K-r also auto-aligns HDR shots so you have more chance of shooting HDRs successfully without a tripod. Not really a deal breaker!

I got to pick up both cameras last weekend, and the K-5, at Jessops in Brum! They didn't let me touch the 645D though.

Maybe she found the receipts for the lenses... and compared to the receipt for her engagement ring...

Those two will be much quicker, with faster AF and FPS, and higher resolution and high ISO quality.

Pentax are rumoured to be bringing out an APSC mirrorless camera this year - it might be worth hanging on!

It looks like dust. Try the camera's electronic cleaning function, and if that doesn't work, you're on to shifting it yourself. But there's no need to panic about it!

I would post a closer crop before taking any further action - can you show a 100% crop of the darkest spot and a couple of the other fainter ones?

In terms of sorting it out, you will need to contact your retailer.

Thanks for that, I was hoping that might be the case!

Those are stunning shots, but dont forget you can still do this with the K5 in Live View / RAW + jpeg mode

I used to enjoy the method of composing on-screen with my c5060 - it also had a flip screen that encouraged you to find interesting angles.

PZ70 arrived today. Looks good, like a mini DSLR! (Actually scratch that, it's slightly bigger than my K7...) It's kind of ugly but in a cool way!

Should there be slight 'give' in the film door? When I push it it moves by about half a mm. Not sure if this is normal for plastic SLR cameras.

I like your set, especially the main image!

It's a grey seal, thankfully we don't have leopard seals in the British Isles!
