But many of those photos RobL refers to in that gallery are composites or partially defocussed and others HDR'd. There might be one odd one without much PP, There's one shot of a young blackbird standing on a fence. The bird is sharp enough but the point it is standing on is way out of focus. That's post processing at work. The cityscape is HDR'd and are most of the lake scenes are heavily HDR'd. None of those adjustments in post are minor. If he says somewhere they are he's kidding!

From what I can see on his website he doesn't say he 'gets it right in camera.' What he does say is 'What I see and what I feel when being there is what I want to transport to the viewer.' That's not the same thing.

If I'd used a longer lens I would probably have suffered from camera shake and frightened off the beast with him thinking its a blunderbuss. Then if I'd gone indoors for a longer lens he'd no doubt have moved on and I wouldn't have had a photo at all (been there, done that in the past. Net result nothing!)

Focussing wasn't an issue. I say this because some seem to say they end up focussing on branches rather than the subject. The secret is just to use centre spot, Pentax Spotmatic style! Multi focus points would have ensured it wasn't in focus.

For those that were users of film SLRs the K-1 will immediately feel right as the lenses suddenly do what they used to do. It's a revelation. Those who were not film SLR users may perhaps find a bit of a learning curve, albeit I suspect a very short one!

Thanks for the complimentary comments, You'll gather I was pretty chuffed to get that end result from that image.

I really went out to do some gardening this afternoon!

Original image: 7376x4932
Cropped image: 681x605

So the width is less than 1/10 of the original.

Had the camera been set to APS-C the full width would be 4800 pixels (the actual image would still the same size, albeit cropped in camera) so that makes it about 1/7 crop (linear value, not squared) from APS-C.

I reckon the squirrel needs to visit the chiropodist to get his toe nails clipped!

Actually I wasn't as close as it appears, there's so much image definition with the K-1 sensor it cropped really well.

Suppose ideally I could have used a longer lens but seems it didn't really matter.
If that's not an advert for the K-1 I don't know what is!
A good job there's no AA filter to destroy definition.
So much for NOT relying on photos straight out of the camera, but the only edit is the cropping.

All cameras may fail to focus on occasion. Things like poor light or a low contrast subject can be a problem. Also trying to focus too close.
Is the problem repeatable? If so take it back to Jessops with the receipt and they'll either help you sort out the problem or get it repaired for you (presumably you have at least a 12 month guarantee.)
Without seeing the camera and the way you're using it it's hard to say what the problem might be from a forum post, that's why it's best to get someone else to look at it for you.
Just say to Jessops you bought it from them last December (they'll have a copy of the receipt on record if you've lost it) and say you suspect the camera might have a focussing problem; do they agree?
If it works, it's persumably OK, if it doesn't then they have the proof they need to get it fixed for you.
Anyhow, welcome to the Pentax User forum and hope you succeed in getting it sorted out.
