I personally love Pentax, and Always have. only reason I ditched them and moved back to Canon was that they didn't have a DSLR that shoots video with the framerates I like until the K30 came out (no 60fps? ugh) and the K-x just wasn't working for me at the time.
I still shoot on lots of Pentax K mount glass and it's awesome... so in tribute, I give you this... Pentax's Full Frame Prototype... the K-1.
due to come out in 2001... as a 6mp full frame professional studio camera. Would have beat out Canon's 1Ds and Kodak's DSS Pro, but Pentax figured that the Phillips sensor was not what Pentax ultimately wanted, and would have cost way too much at the time to introduce.
They have been talking about a full frame camera introduction for the last 4 years... we'll see if the k-1 ever happens for real of if they just say 'fuck it' and stay with the k-5 to directly compete with the 7D and the D7k's of the world.
