Ricehigh pointed to a main dealer's site that listed it as discontinued over 2 months ago. It would have been listed by the dealer even earlier.

The same dealer already has K-5 II and IIs kits listed and priced.

Just a re-badged Tokina 80-400mm would do

£6k is ridiculous for what is supposed to be
just a telescope

The K-5 was discontinued months ago

It does look like Marlon Brando and Vivian Leigh

That one's very good.... the piece of cloth in the
bottom left corner looks a bit awkward though.

I think it would look better without the dummy head
and stand. Maybe darken the area where it was level
with the window cill/board. The coat hanger is OK.
The lighting is quite nice.

Just a couple of further points.

Most sensors are expected to last for 100,000 shots so if
you find out how many shots you have taken, you can quote
what percentage of use you have had or what percentage of
its expected life the camera went through before it failed.
There might even be a claim against Pentax there.

Pentax don't seem to acknowledge any faults that occur.
Early K-5's were plagued with stained sensors, but it
was never official. Also the lens release button falling off.

Have a look at some of the consumer forums such as "Which" and
http://www.moneysavingexpert.com/

Collect what evidence you can off Pentax related forums to
back up that this is a manufacturing fault.

Sony replaced a lot of sensors in various cameras for at
least 5 years because of a manufacturing fault. These
weren't just Sony cameras.

Good Luck!

Do you pronounce 'am' and 'M' the same?
