Impress Watch from Japan have recently reviewed the new Pentax digital SLR sensor cleaning kit. To get rid of the dust particles, oil and any other rubbish you should press the cleaning steak with its orange lollipop-like head to the low-pass filter covering the sensor and then clean the head from the dirt with the special paper supplied with the kit. It will work with any Pentax digital SLR cameras from *istD to K10D as well as other manufacturer’s DSLRs.

Recommended price in Japan is 4,200 Yen which is about $35.
