Hi,
there is another housing for the K10D. It´s called blue-box and is manufactured by bruderuw-technick in Germany. But I wouldn´t recommend to purchase a housing there. That thing is not worth the money, neither it´s a german quality product. It´s very cheap, and so is it´s quality....
Another manufacturer from germany worth asking:
BS Kinetics GmbH - Unterwassergehäuse, Underwater housings, Underwater housing, tauchen, diving or
BS Kinetics GmbH - Unterwassergehäuse, Underwater housings, Underwater housing, tauchen, diving
Housings from UKgermany are appropiate and very good quality, but they are looking like a bread box and they are heavy. Compared to other well-known housing-manufacturers, you have to pay a lot for what you get. That´s comprehensible as UKgermany is a sole distributor and there is no competition on the market for K10D-underwaterhousings so he can ask for money as much as he wants.
I know he just overhault the present K10D housing to fit in a K20D. Especially with the live-view it is a nice feature for underwater shooting and no need anymore for UK-Germany very, very, very expensive view-finder. The view-finder usually is half the costs of the housing.....
That´s why I didn´t bought a housing from UKgermany
Anyway, I will just keep waiting for better prices or other manufacturers as I´d really like to take the K10D or K20D underwater.
Here is a test report from Herbert Frei, but it´s in german:
