ISO performance from the K-x

All in a K10D body.

The above in a K-7 body rather than a K10D body but with FF, not so much because I want/need FF but because I want the larger VF.

I don't need a tiltable screen, but will have it if it doesn't impact on longevity and useability.

Shouldn't they be able to do that with some optics or will that darken the VF?

any increase in magnification will always be at the expense of brightness, and presumably size of the optics needed in the prism housing.

Thats why prism finders are always higher mag than mirror ones, the pentamirrors sacrefice light transmission for cost and weight so to get the same brightness you have to drop the magnification.

Yes, as Mongoose states, any attempt at magnification is at the expense of brightness.

oh I thought of something else,

somehow link the AF system to white ballance so the AF is accurate under all lighting conditions. It's irritating that it goes funny under tungsten light, right when you want to be using f/1.4 because it's dark so don't have the depth of field to accomodate out of focus shots.

for me the previously popular faster af, faster burst mode etc etc, but I'd be most happy to see an articulated flip out lcd screen (or better yet a detachable (even if wired though wireless would rock) lcd screen that also works as remote) but touch sensitive with "Spot focus" and "Spot metering" so you can touch the screen on the point you want in focus or to meter....

combined with video and the ability to program a rack focus shot (ie a start and end point for the focus) and an audio jack...

that and dual card slots so you can shoot video and still simultaneously.
Fired many shots. Didn't kill anything.

.

that would be pretty snazzy, though you'd have to be able to disable it so as to avoid nasally operated AF and metering

Is that still so with the K7, i thought they improved that quite a bit.
BTW for the ones wanting Faster AF the 645D has a new SOFAX (AF sensor) lets hope it boost performance

I understood the K7 does have WB AF correction... can't remember where I read it though

I agree with Mike, it would take some more.

What I do like is that Pentax would be split up, I fully trust Hoya with the lenses, now why don't go and develop that further and leave the body up to Kodak or Samsung which in turn I don't trust with the lenses.

However Hoya did make the successful K-M and K-X and the K-7 isn't doing bad either right and we like the way these camera look and feel so in my eye they Hoya aren't doing a bad job at all.

I can't really agree with this. Why on earth would we want Pentax split up into two disconnected companies? And why Hoya to make lenses - they don't make lenses. Just as Kodak don't make camera bodies.

Surely we just want Pentax to do more of what they are already very successfully doing?

Hoya used to make Camera lenses, I had a 300mm F 5.6 though it actually gave F8 in reality. I used it for around 6 months until it jammed on my MX at Greenham Common Air Display and i wrecked it trying to get it off!
So i went out and bought a Pentax 300mm F4 which i still use today!

How would that improve the image quality, Paul? I always thought the 10mp CCD produced excellent images, particularly at low ISO values.

They marketed a range of budget lenses in the 1970s, but whether or not they made them is something else.

I have a very nicely made Hoya 24mm M42 screw lens in its original case. It's lovely to use and produces minimal distortion.
