Summary

Our Score:

9

User Score:

A range of test shots are shown over the next few pages. Here, the full size image at the minimum ISO setting has been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been placed below it in order for you to gain an appreciation of the overall quality.

----

----

At the minimum ISO 64, picture quality is outstanding, with rich colours, tons of pin-sharp detail and no noise at all.

----

Likewise at 100 ISO picture quality is superb.

----

At 200 ISO there is a hint of chromatic noise in the darker areas, but detail and contrast are unaffected.

----

There is more colour speckling in this 400 ISO shot, but the lettering in the motto banner below the crest is still plainly readable.

----

Noise is starting to become a problem at 800 ISO, but the sharp edge detail and colour accuracy would still make a usable print.

----

At 1600 ISO, the highest manually selectable setting, image noise is now quite bad across the whole image, and fine detail has been completely lost.

brilliant site which I discovered only yesterday. I was ready to buy this camera on the basis of your otherwise excellent review until I saw the trees in the background of the wide angle photo of the brick building on page 6. What on earth happened there? Almost no resolution of fine detail and no tester comments either. That's one sale lost to Pentax I'm afraid.

I've had this camera for 9 month and the screen has broken twice. The first time was after just two days. The after-sales services from Pentax is terrible. Nothing is included in the guarantee. If you want a camera where you have to pay £70 in repairs every 6 months, this is for you. I'm throwing mine in the bin. Its just not worth repairing. I'll never buy Pentax again
