Body construction K-5 compared with competition

How do you guys(and girls ) compare the build quality of the K-5(should be the same as the K-7 I think ?) to that of the competition ?
Like a Nikon D300s or a Canon 7D ?


I've made a picture with the camera body's all together here:

click on the image for the high-res picture

Looking at the pictures I would say it is comparable but in real life ?
And looking at the K-5 pictures I can't see the mount, it is not attached...

the body is one thing but what you should check is just how the parts are put together, who knows if a hard knock could dislodge a chip or mis-align something.

The K-7 has full metal front and bottom - built like a armoured tank...
The 7D is pretty solid as well, but the D7000 looks like "cost saving"

Build quality is not just the frame but the quality and durability of other elements of the body: - the LCDs, the switches and buttons, the seals, the weatherproofing, the doors, the exterior plastics etc - and how they are all put together.

At least the K-5 body and the D300s are relatively 'old and true' designs, closely based on previous bodies, and thus have a track record of user experiences one can look into. The D7000 and 7D are newer designs with less user history to assess build quality from.

For what it's worth, the D7000 and D300s are assembled in Thailand, the K-5 is assembled in Philippines, and the 7D is assembled in Japan.

I would rank them for body toughness:
K-5 D300s (tied)
D7000
7D

So you think that the D7000 is better built than the 7D ?
I would think that the 7D, the K-5 and the D300(s) are all on par with each other but the D7000 a tad behind.

lens mount of D700,K5 and 7D is definitely screwed to a plastic/resin base, but D300s mount looks like being mounted to the metal base. not 100% sure as there's no picture of D300s back.

So, it's D300s>K5=7D>>D7000

Your ranking is based on what? The 7D is definitely not a "newer design" in fact it was released on September 2009 and I'm sure it would be easy to find feedback on its build quality.

The 7D lens mount is directly on the Magnesium body:

K-7 is pictures without back cover which is plastic. Also, mount is screwed to plastic.

The K-7/K-5 have just as good build quality as my D700 and better ergonomics to boot.

I recall reading somewhere that this was a feature, as in providing a breaking point which was relatively easy to repair and would hopefully prevent the (presumably metal) lens mount from breaking in case of impact. No idea if this really true, but it makes some sort of sense to me.

I think you meant the lens mount of the D7000 not the D700. The D300s has an almost identical body to the D700.

I think Nikon should have put a metal front and plastic back on the D7000

That actually makes sense to me as well. A bent mag body would be more expensive to replace than a plastic/composite mount.

The reason they using magnesium is for weight consideration and wall thickness. A 3rd reason is that magnesium is a good heat dissipator, plastic is an insolator who is not very good for high end camera. a 4th reason is electric shielding , standard plastic is not
I am working with OEM all the time and I can mention that today with more than 10,000 different grade of plastic , you can beat metal almost anytime in strenght, toughness and cost.
But if you need a very thin, light and extra stiff case, magnesium is the way to go. When you look at the cut of the K-5, not a lot of space left because Pentax camera are selling this as a feature (smal size)

rawr rates the 7D last because he hates Canon that's it, but in reality it is pretty much as weather sealed as K-5
7D #1 Weather Sealing
try that with the D7000 and your screwed.
