Thanks, all, I will try out a daylight bulb and see how it works out. Most of my lenses have UV filters on them si I will try with and without the filter.

I just bought a lamp that has a very nice reflector on it, the lamp gives off a very nice, fairly narrow and even light. I want to try using it in the studio, in conjunction with fill-in flash through a soft-box. Does anyone know if there are any light-bulbs available that would be the same colour temperature as my flash? Preferably a bulb of the energy-saving variety, as I will then be able to use a more powerful bulb.

Because they are square with white borders?

I think the statement by the judge that he is not going to post comments will further reduce the entries on what is a fairly difficult subject anyway.

Make sure the aperture is wide open and that the grass is sunlit. The filter blocks so much light that its probably not getting enough light to work out the WB. If you still have problems also set a highet ISO while you set the WB.

Thanks, Paul, I will see first what Mathers come up with. They have always provided me with excellent service; I have purchased three cameras from them and a couple of lenses over the last few years. They also gave me a free lens (albeit an old 75-150mm) last year. Though perhaps they should have tested the camera properly before returning it.

I'm sure they will be reasonable in dealing with this problem. It's Pentax and their servicing (Johnsons) I am p*^^ed of with.

I have emailed Mathers, who sent the camera away for repair last time, and told them I want a new camera, will see what Pentax say. I am pretty p*$%ed off, as you can imagine.

For the previous repair, before sending it back to Mathers, I took the camera to Pentax's main repair centre in Osaka, but they wanted to charge me for both fixing the lens release and the horizon indicator They said the two year warrantly only applied in the UK, never mind that the camera faults were all down to them. Absolutely appalling customer service.
I saw that Pentax had recently come out top in some survey of customer satisfaction, but they never asked me! If I didn't have so many PK lenses I would be swapping systems.

What may help? There's no link or anything in your post, Paul? I will be getting my camera repaired in the UK again. I am going to Osaka again soon, but Pentax Japan have already proved to be a complete waste of time.

Just got my K5 back after it being sent away to have the lens release button replaced and the horizon indicator straightened (it's still one dot out)...I wasn't expecting them to convert it to manual focus at the same time. The focus select switch is not working, it only moves to two positions, both of which don't change anything. It's stuck in manual focus, and it was working fine (using a rivet to change lenses) before I sent it for repair.....looks like another 4-6 weeks without a camera

Personally I think Pentax should replace the camera rather than make me go cameraless yet again.

I've just received the Adaptall II 80-200 (model 30A) from Mike-P, the lens is in excellent condition and first impressions are that it is a very good lens indeed! A bit of a beast at 1.2 kg, but it handles very well.

I've just got mine back after the same problem, also had the horizon indicator recalibrated. Great service as usual from Mathers.
