I can't vote in this poll because none of the options really fit my situation. I am not "leaving" anybody since I have not married any camera brand. I like Pentax quite a bit and shoot several Pentax cameras, film and digital, but I shoot lots of other brand cameras as well. I am not worried whether Pentax brings out a full frame camera because I went ahead and bought a used Canon 5D, the first version. I actually really like that camera and shoot it fairly often when I need a digital image for something beside web posting or a quick shot to e-mail. I have held onto my K7 and a couple WR lenses but I rarely pull it out anymore. I do still use my *ist DL2 quite a bit because I like the image quality, and 6 megapixel is actually plenty for most of my digital imaging needs. If Pentax finally introduces a full frame I will be thrilled, but I seriously doubt that I will buy one now.
If you think about it, full frame is just 35mm, and I have a bunch of very nice 35mm cameras along with a scanner. I am actually more interested in the Q since that really looks like a top notch piece of gear. I would buy one now but I am afraid that Pentax will do with that like they did with the LX, and leave it hanging out there with no upgrades or additional lenses. If they do come out with a Q2, and a few additional lenses, I will be all over it. I may buy one anyway. IMHO that little camera is the real future of photography. Small, flexible, and really good images for such a small sensor. Obviously it can't compete with full frame images or even with the top of the line APS-C images. But in its class it is one of the finest. It can be a real groundbreaker, just like the Leica was in the 30s, if Pentax will only commit to the platform instead of letting it die. A few improvements, a couple more serious lenses, and I seriously believe that little camera will be on its way.
As for full frame? Lots to choose from and trying to catch up with Canon and Nikon from behind is a mistake in my mind. Instead Pentax needs to flank them. The Q and the K-01 are a great start, just keep those balls rolling. Pentax should keep aggressively developing that little Q and let everyone chase them for a change!!
