I feel the same way. Between the K10D/K20D, Nikon D300 and Canon 40D, I find the Canon has by far the worst overall ergonomy.

Well, it *could* be a matter of habit, since the Nikon's control layout is somewhat similar to the Pentax's.
Could be... I'm hoping I just love it so much because I'm so used to it from my 20D & 30D... I've helped my parents with their Nikon... & its cacafied menusystem and button frenzy...

I could get over it I'm sure... its performance at low light, high iso that I'm interested in...

the camera can Pink with Green Polka dots with fluffy bunnies sticking out the sides for all I care... so long as it performs...

k... well maybe that's extreme... that would be tough on the street photog crowd


PS... you're almost up to 3000 posts.

I did not mean any negative notion against FF, just noting that it often brings some extra bulk and weight. Here is a picture returning the advantage to Canon :


vs. K-m:

Steel as in Fe+C? If it's made just from that material then it will be even heavier than the K10D/K20D.
No, it will just be smaller.

Steel is 4x the density of Mg, but the strength and stiffness of steel is correspondingly higher. The important parameter is the ratio of strength:weight.

Therefore, the volume (size) of steel only needs to be ~1/4 of Mg to be the same strength.

If sizes/space is not an issue then soft low-density materials such as Al or Mg are suitable because you can use more material to make up for their low strength. Another advantage is they are relatively soft, so they are easy to form into complex shapes which means lower manufacturing cost.

If miniaturization is a priority, high-strength materials such as steel or Ti are a better choice. But they are very hard, so it requires great amounts of energy to form them into shapes.

I know that dave9t5. I was simply replying to ogl because he stated that the camera will be made only from steel (inner and outer shell) ... that's why I said a camera built only from steel would weigh more than the current K10D/K20D which have a metal inner shell and plastic outer shell.

OK guys we're just shy of the official release, and still no solid specs. Come on what are all those Russian spies up do? Do we have to wait for them to sneak into Norway and give us info from the official presentaion ( Where I hope Pal gets his hands on the real deal and posts some real image samples and vid clips ).

OGL dude like slip us some good info here

I can assure you that the chance of that is absolutely zero...

From a German photographer having shot with the K-7:

"I took delight in the fast and super silent shutter sound."

"A K10D is significantly noisier and feels slowlier when pressing the shutter. In both, single exposure and burst mode."


"Besides the LX, it is the only small camera which fills me with joy (ed. eine Freude machen) when handling."
The bold text excites me. It's about time the shutter is quieted instead of the "zip zip" sound.

Definitely not all out of steel...that would weigh a ton like you say

Well, I wasn't saying it's completely made of steel. I was simply questioning ogl's statement. Since he sometimes makes unclear statements.

No if it is a composite.

Right, Nikon's menus *are* the pits.

Each brand has its problems, it's just a matter of which one bother you the least and/or you get used to the easiest

i don't mean to beat on nikon, but as far as entry level and near it go (i only used a d50 for a reasonable extent of time -- about 6 months and a few k shots-- so i won't comment on the others), i am sorry, but having to use three hands, your nose and some of the fingers on your feet to change a setting might be nifty, but it gets old quickly

Ah, I understand what you were saying.

I for some reason thought that the K20d was magnesium. Of course, it is listed as plastic shell with steel frame.

For reference, some images of current inner frames:
K10D / K-m


If the plastic shell is replaced with steel shell, then the inner steel frame is redundant and can be eliminated. The steel shell becomes the frame, which saves weight and volume.

It would explain the squarish traditional shape of the K-7. A (semi-)continuous steel shell would be a much more difficult shape to manufacture compared to either a molded plastic shell or bolted sheetmetal inner-frame.

Moving the internal steel frame to the extreme outer limits of the body has a couple of advantages:
- opens up a lot of space on the interior, so more space for "goodies" such as larger VF, or electronic guts (video circuits, sensor cooling), etc.
- increases the rigidity of the body, allowing less material (smaller/lighter).

My money is you are correct. To do what I said not only would you have to heat the mold but also the steel skeleton part before you put the skeleton into the mold and inject the plastic. All of this would make it more expensive. If Pentax did do this thou it could be stiff like metal (this is part of why some like metal) and use a softer plastic so it would not crack. This allows Pentax to use the best the 2 materials properties and minimize the 2 materials weaknesses. I have seen parts built like this but mostly to reinforce the attachment (screws) point.

ceramic plastic composition with steel chasis. aluminum and steel don't mix because of reaction of dissimilar metals.
