The K100D with two zoom kit was on fire sale locally, so I picked it up
after playingn around with these two for almost a year, I added a SMC Tak 50 to the stable. I loved the pictures (the color! the shrapness!) but hated the fov.... so I got myself more Takumars and still love them dearly. I never even took a glance at the other brands until I'm at architecture school where there are loads of canonikon users.
I *accidentally* acquired an FA 50 and I decided that it's time to set the fifty straight and got a ZX-L with it. I fell into the film hole and interchange my lenses with almost no limitations between film and digital. I have since acquired a small collection of great glass, and have probably used and owned more lenses than everyone in my school year combined; most (all?) of them only have the kit lens. I stay with the philosophy that bodies come and go, but glasses stay (the same price, and usable; if you use pentax). I guess the interchangability / availability of all this great (relatively) cheap glass has made me stay
If only pentax would improve P-TTL and autofocus (which hopefully they do with K-7) I would probably not look at any other brand... (yes yes, I'm eyeing at that Nikon D90!)
I think the next stop has got to be K-7 and the FA limiteds... looking forward to that
