Pentax has released a pair of Single Lens Reflex cameras with an upgraded version of the Shake Reduction feature introduced in their point & shoot line of cameras.
The K10D, a full-featured, weather sealed, 10MP, SLR hit the stores in the USA just before Thanksgiving. You'll find examples and discussion in all of the regular places.
The shot included here was hand-held at 1/8th second. Normally, I'd not be able to take a steady shot at any speed less than 1/30th second. This is a very significant improvement.
Unlike it's competitors, Canon and Nikon, Pentax chose to build the SR feature into the body. This makes it immediately useful with most any lens compatible with the K-mount.
The K10D has been an instant hit. The initial deliveries were sold out within a couple of days.
Here's a gallery of sample shots from the K10D.
