Returned K5 - Where to now?

Apart from anything else, your first image is over exposed for the bright object against a dark background. You need to use exposure compensation to darken the image down. It's also very poor quality, so is it hand held with a high ISO in poor light?

Why not go outdoors and take some general shots in good light so that you can judge the outcome. If you order a new K-5 from SRS it will arrive next day and be fine i'm sure.

Oh dear, such a shame for you. I can understand you questioning your decision.

I can't comment on the lens, since I don't own one and have never used one, but I do have the K-5. My first one was returned due to the stain, and as I said in another post the second one seems good. SRS exchanged the camera without any problems and refunded my the postage for sending the old one back (in the UK I believe they send a courier to collect it).

I think it is the fault of Warehouse Express, not Pentax. They seem to have sent you an unchecked K-5. It sounds like they may have sent you one which had been returned to them, probably by accident.

If you get your money back, and you should, then please give SRS a call and talk to them. They will check your camera for you if you ask them to, and you will get it (post free if you mention your PU username) the day after you order it.

I hope you give Pentax another chance, though I will understand if you choose not to.

In the UK SRS not only sent a courier to collect the stained K5, they were offering to send along a K7 as a no-charge loaner while the K5 was being sorted out! I didn't take them up on it as the turnaround was only 2 or 3 days when I swapped mine in March, but I was very pleased they made the offer. And I'm sure those people who returned their K5s in January and had to wait a week or two for replacements would have been delighted with the offer!

There's something wrong with the two pictures you posted. The look like they've been taken with a 2Meg point and shoot If they are from jpgs you need to set the jpg size to 16M and the Quality to ****

The viewfinder looked small to me but it's OK now that I have put a KPS 1.3x magnifier on it. link

I don't see how they look like P&S images the DoF is impossible for a P&S.

You stripped the photos of the EXIF data so we can't help there.

I've had similar shots from P&S. These were taken at f/2.4 a lot of P&S cameras have similar sized apertures.

The EXIF data is readable in Firefox with the Exif Viewer Add-On.
The light must have been really bad 1 sec at f/2.4 800ISO?

The K-5 has a problem with purple fringing and this can be seen in the first shot. I was surprised when I saw this on some shots I've taken. I hope they can fix that with a firmware update

Looking at the Flickr shot of the brass door handle it looks perfect apart from a bit of purple fringing in the wooden frame.

The Denon shot looks fine and the colour balance spot on
It's probably just a case of getting used to the camera and lens.

PF comes from the optics of the lens or maybe the microlenses on the sensor so nothing that can be done with firmware...

That would mean the Sony and Nikon cameras would suffer from it as well!

Well the kit lens's dof will be deeper than the 70mm at f2.4, but at the same settings the 70mm should be sharper, unless something's wrong with it.

It must be the sensor as the K7 has less CA with the same lenses. Perhaps the others correct for it automatically.

However... I think the CA in the OP's shot is from shooting a bright reflection with a fast lens wide open.

Erm... You don't seem to understand how DoF works. P&S cameras (2/3in sensor) with an f/2.4 aperture will have the DoF of an APS-C DSLR lens at f/25!

I thought DOF was down to the focal length, not the size of the sensor ???

I worked it out by hand and seem to have done it wrong. Should be APS-C f/8 for that comparison and f/9 for 1/1.8".
