Magnesium is what most higher end cameras like K1 and K3 use.

Where exactly is Mg being used in K1 and K3?

The chassis is Mg alloy.

"Elegance of operation" -- Pentax
"Heavy for its size" -- DPR

The chassis is the mirror box which is plastic. Did you mean the outer shell?

No Oiche. Better be slow with firing here. The chassis, as commonly referred to, is a steel frame inside the body. It is made of stainless steel. You can see it here: https://www.dpreview.com/forums/post/59269106

The mirrorbox is polycarbonate and the outer shell magnesium alloy.

Haha a lot of people are confused as to what the chassis is.

From this guy's comments steel is nothing to write home about , he has a point...

"Nikon has done away with metal sub frame chassis and have moved onto single piece carbon reinforced plastic chassis as this is much more resilient to impact damage.

This is found in the D500 and the D750 and one of the D3XXX lines

On 1 hand you a steel chassis that has no rigidity and gains that rigidity when combined to plastic components. Or you are stuck with singe molded plastic with which the mirror box and the external body panels are directly attached to.

I don't think one is better than the other, they are just different"
