PentaxForums is really one of the nicest forums out there. I've been visiting regularly for the past 5 years or so (even though my account is new). It's filled with helpful info, and just feels "comfortable".

I would expect the 135/FF format to be more practical than the 645D for most purposes.
You've already mentioned the limited ISO with the 645D. The 645D has roughly 12.5 stops of DR; even the current Super35/APSC sensors are already at 13 stops or so. There's no live view on the 645D, which makes it cumbersome to use for product work. Also, don't forget that shots on the 645D will take a few seconds to finish saving to card. The 135 body should (hopefully) have better AF capabilities than the 645D as well.
Typically medium format sensors from PhaseOne and Hasselblad have better color fidelity than 135 sensors, due to the narrower band-pass of color filter arrays they use. However, I'm not sure the 645D's CFA is any better than the existing pentax S35 sensors. The 645D would be slightly higher resolution, especially if the 135 sensor turns out to be 24MP or so. But even then, the difference between 24 and 40 isn't THAT huge.
Like all things medium format, you're really paying for the ergonomics and the showmanship of using a giant sensor. Most of the folks I personally know (including a couple of big-budget ad campaign shooters) are using strictly 135 sensors for their work. Some still have their P1 gear, but only because they enjoy using it for personal projects.
I suppose it's like an old classic car vs new models: the new model is objectively better in most ways, more affordable, and more maintainable. But the classics have that touch of nostalgia that appeals to those who can afford it.

Hi,
I've read that the K-50 has af point illumination; I'm curious as to whether it is done via an LCD overlay as in Nikons.
Specifically, without any batteries in the body, does the K-50 still allow a normal view (i.e. not dark and blurry) through the viewfinder? Any information would be greatly appreciated.
Thanks!

How's the autofocus speed/accuracy on the MZ-S? I love the styling and ergonomics of that body, and am thinking about getting one to play with. Thanks.
