This guy over at Chris Willson's flickr Photostream is amazed to hear that you can't shoot portraits with nice bokeh with the 645D: Monkey Stare | Flickr - Photo Sharing!
Jeeze you guys are touchy if someone says anything negative about a Pentax product. Of course you can shoot portraits with a 645D, but the originally point was, and this is my on personal opinion, that as a portrait photographer I think Canon and Nikon full frame solutions are the better options due to their current lens line ups and for the fact that the cropped 645D sensor isn't that much larger than 35mm in terms of focal length equivalents. I never intended for that simple opinion to expand into a 2 page discussion.

I've owned and used Pentax products for 15 years now, I get no joy out of disagreeing with their product strategy. Not everyone is going to agree with what they do. This is simply one area were I don't agree, so carry on as you were.

They are worse:
Huh?
I repeat, 135 format optics can't achieve MF format quality without losing some significant parameters. If they increase sharpness, the bokeh is degrading and so on.

This is funny. I wonder if this are the same people who claim that the difference between the sensor-size of 645D and 35mm is to neglect and that just about the same results can be achieved, as these who claim that APS-C can never reach 35mm
Yes, there certainly is some truth in both points of view, but let's keep reasonable, and be aware that an reduced web-image may not show the incontrovertible advantage of a 40 Mpix sensor with a high quality lens.

Btw. Art, i must say, even if the images you posted are 'nice', I fail to see the 'magic' in the bokeh, which seems to me quite...well... not just hitting my taste, a little bit of doubled structures and somehow... maybe almost pathetic in their approach stressing the thin DOF. But of course, de gustibus non est disputandum, right?

It isn't magic at all. Modern Canon, Nikon and Zeiss lenses are not good at this point.

The 200mm f/4 isn't going to give you that same look.
Hasselblad have the 100mm f/2 That is extremely popular for portraiture and according to OGL, Pentax will be coming out with a lens with a similar focal length so if pentax can make a 105mm f/2.4 for 67 format they should at least be able to make a 90mm or 100mm f/2 and let's hope that pentax makes it apochromatic so we don't have to deal with bokeh fringing.

I know it is a way bit off topic, but this GPS unit has some "interesting" features that he could not say anything about . . . .

Speaking of which, the ironic thing is the larger 6x7 has a faster lens than the 645. Clearly, it can only mean that they haven't made one because they didn't want to make one. In the mean time, there's always that 6x7 to 645 adapter. It passes aperture control too, to boot. Too bad my local camera store asks 400$ for it. What a rip.

These can be purchased new here:

japan exposures | films and more (formerly Megaperls Japan Webshop)

The current price works out to CAD $303 or $USD 317. Shipping to Canada was $17 via EMS; 10 days from order placement to having it in my hands.

The prototype is rather large, maybe f2.

It certainly looks like it, time will tell.
