1) SR is very bulky and for mechanical reasons cannot be shrunk much.
2) FPS is necessary for high-end DSLR's and the extra bulk necessary
3) Power and cooling and video and rear LCD all take up space. Lots. Add in video and you need some serious cooling.
4) Not true. My Nikon D40x was a touch smaller than the K-r and the D3100 is about the same size.
5) The Sony A33/A55 are thicker because of the EVF extension and rotating LCD, but they weigh less than the K-r and in the hand feel about the same size.
6) Yes. So what? The Canon sells about 8x as many. Marginal size differences have little to do with sales. People buy the bigger cameras more than the smaller ones, so the sales data says.
7) You're arguing at cross-pusposes. The Fuji is a high-end, single style camera and the 645D is extremely high-end.
8) Where would Pentax be now if there was no DA* 16-50, 50-135, 60-250. Nowhere. Probably 25% of the base would be gone and 40% of the margins.
9) There seems to be a flawed logic in that Pentax can make a smaller FF system without giving up something like SR or an OVF, ...
I personally think that Pentax doesn't need to compete directly with the big two to have a 35mm FF camera available and be successful with it.
2) Your opinion, however having higher FPS would be a positive feature.
3) Yes, look at the K-5 cutaways I posted a link to earlier for how Pentax constructs their cameras.
4) D40x? 3fps, no in body SR, I'd assume no AF motor either. My point is pound for point Pentax makes smaller cameras. The D3100 however is closer, but it still will never have in body SR and in-body AF motor. That means Pentax fits more inside for a given size, so it could in turn mean Pentax can't make a FF smaller than a D700 with SR inside, but it's all speculation either way.
5) EVF extension and rotating LCD are design choices. According to you those cameras are thicker. I'm not talking about weight, but physical size. Otherwise I would be happy with plastic lenses instead of DA/FA Limiteds that Pentax sells.
6) Yes. So what? .... Yes, I think it is well known people shopping for something in that level would choose between the two. The Pentax is smaller. I've specifically had 7D users talk to me about the K-5 in relation to their camera with the same thoughts as I have with the two.
7) I'm naming specific examples to prove my points and they are not related. I believe the Fuji is successful because it has a large sensor, an optical viewfinder, and small in size for what it is overall. There are of course trade offs, such as that fixed lens. There are many people who want compact full featured cameras with optical viewfinders. I will not be buying one of those mirrorless ILCs, but the Fuji is appealing. The 645D successful in general for for various reasons, but my only point in mentioning it is that it came out with a single new lens. Pentax sells it at a fixed price to make a profit. I guess time will tell if releasing it with a single lens was a good idea or not. From what I've read in the past, They are selling more camera bodies than 55mm lenses, so these existing 645 users have lenses they want to go digital with. I think the same can be said for for people with 35mm full-frame lenses in M42/K-mount.
8) Yes, Pentax should have a full lens lineup eventually.
