It is a disturbing image. But I am very impressed at how fine and precise the cutting blade must have been.

Imagine the labor that was spent folding and forging that blade, to be able to take on Pentax body. There is some marketing potential here, somewhere.

.....yawn

You people wear me out.

Here's some Moire from a scanned film shot just so you all can obsess over it:

You need to reconsider your dedication to Pentax in that case. We are here for the long haul.

I'm fairly certain that cut was done with a high pressure water jet.

For high precision cuts, generally they use water jets or lasers. A physical blade that thin would be too fragile and/or unstable to cut through metal. A laser would also be unsuitable due to the "melt zone" deforming the components, not to mention potential nasty interactions with the prism and mirror.

Perkele!

Never thought I would run into that song here on PF.

I´m originally from Vaasa btw, and I guess I´m quite stubborn as well.

Would that have been one camera cut in half or two? I would think it easier to do an approximate cut and then grind it to the right point and then repeat the process on the opposite side of the second body.

It most likely is done by a diamond blade on one camera SAVE the BODIES.

If it was done on two production models, then somewhere around the world, a potential Pentaxian-to-be is lost, his would-be camera sliced for display purposes! Oh, the horror.

I have a Spotmatic (& a 135/3.5 ST) cut in half by the factory. They used a diamond saw in the "old days."

Please post a picture, would love to see it!. All the pictures, that I have seen of the bodies that have been cut, show saw-blade teeth marks.

I'd imagine there are too many delicate and moving parts (the mirror and circuitry for instance) for grinding. Stuff could go flying or shatter. That kind of rough treatment would usually be reserved for relatively homogeneous substances.

Water jets have very high precision (0.02 inch/0.5mm cuts or less depending on the type), and are extremely powerful (can cut through several inches of solid steel or titanium). The computer controlled system is capable of cutting very complex and even 3D shapes. A simple straight cut like this would be child's play and done in seconds.

Pentax JP have updated their K-5 II /IIs product page.

For the K-5 IIs, they have a page that shows one [not very useful] illustration of the extra detail to be seen in the IIs,



The page also shows some examples of moire and false colour, and suggests:

K-5IIs may depending on the conditions of the subject and, moire and false colors stand out. In that case, in consideration narrow the aperture, such as changing the shooting distance, may be able to suppress the moire and false color.

Thanks for posting.

AFAIC, I don't see any extra detail; just a bit more contrast. Hit the K-5 II shot with some sharpening (+ a touch of WB) and it will look the same; the fine details is all there already.

Indeed. I bet for this IIs example image they did just that.
