Pentax USA just confirmed that the K-5 in silver will be released here.
Another interesting product is the new pocket-able waterproof camera, the OPTIO-WG1.
That looks like a seriously useful digicam. Waterproof, GPS, and substantial rubberized construction.
The 645D also has a new wide angle lens available.
I personally think they hit a home run with this update. I wanted a K-7 in silver, but that was limited to a 1000 piece production run in Japan. Now with the K-5 Silver available in the USA, it’s a really tempting option. The question is where to find the funds for one though…
