I use one with my ball head. There is a level on the head, but with the camera in place you can't see it.

Sounds like a challenge anyway!

Think he reads PUforum? I love WTD!

Whilst I enjoy Luminous Lanscape a lot, and find it very helpful, this guy really doesn't live in the real world. If you read the article about the equipment he took on safari with him it is unbelieveable - especially given that you have a luggage weight limit of just 15Kg on the small planes he used.
It seems he thinks you can only get great photos with the biggest most expensive gear around. Ken Rockwell does have a point - that photographer must have an eye for things regardless of the camera he uses. Yes you will get a better quality picture from an expensive DSLR with expensive glass than you will from a throwaway camera. But whether you will get a more pleasing picture depends entirely on the person pushing the button.
I think Ken Rockwell makes several valid points.

There are tripod tracks worn into the rocks at sites where Ansel Adams took his photos, from people, who instead of being inspired by him to attempt their own fabulous photos, feel the need to duplicate exactly what he acheived.
I have two Adams hanging on my wall. I love the photos and they inspire me, not to go off to get a photo of a moonlit Half Dome, but to learn to use light as he did, in my own surroundings.

The fact that I am happy with the photos I can take with my Ds is one reason I haven't yet moved on to a newer model. I'm still in two minds about spending so much money on a camera, when the one I have is for the most part good enough for me. I don't think buying a k20D will make me into an Ansel Adams (nor would I want it to), and i, not sure I will take any better pictures with it. The quality will be better (hopefully) but the content will still be the same as I would have taken with the Ds.

End of my rant.

According to Pentaxforums Pentax are now aware of the problem. Apparently on the K200d you can turn it off, so it sounds like an oversight on the K20D.

The converter is extra and not really worth having as the Bigma is already slow at 500mm, and the converter only makes it worse.
Good lens though. As amilner says check the classifieds on the forum!

Yes, it's a shame it's a Friday, but their specials are always on Fridays for some reason.
Pity Good Friday isn't a day off on Holland.

If it weren't for kids moving and borrowing money from me left, right and centre I'd be tempted myself.
