I would really love a FF Pentax. I got my first camera back around 1990. It was a Pentax Asahi K1000 with an SMC Pentax-M 50mm 1.4 lens. I had spent a number of years collecting more SMC Pentax lenses, all primes, and had a rather large collection until my roommate stole all of my camera gear! SO much hate at that time
After that I ended up with a Nikon F2A Photomic and another collection of Nikkor prime lenses. Those helped me win scholarship that paid for part of my Associates degree while I was studying graphic design! Then in late 2006, my apartment was broken into while I was working for the local newspaper, and someone ran off with $6,000 worth of my stuff, including all of my camera gear. My insurance company screwed me royally, so I was unable to replace almost anything. I saved up for a while, and got myself a Canon 40D dslr, which I am using currently.
Been holding out for Pentax to come along and release a FF camera and then I'll be selling off my entire Canon collection and moving back to Pentax, where it all started for me!
Currenly, the Pentax K-5 and the K-30 are both tempting to me, but if I'm going to return to Pentax, I want to do so in a big way. So for the time being, I'll happily use my SMC Pentax 50 1.4 on my 40D, and wait quietly in a corner, preparing to pounce on a new FF at it's first appearance!
Until then, I'll keep snapping away at shiny objects!
