Re: "Disadvantages of 6X7"

[Paul Stenquist]

Yes, all but the earliest Pentax 6x7s have mirror lockup. Of course the 
shutter mechanism is fairly hefty as well and can cause vibration at 
speeds around 1/30 and 1/60, particularly when shooting on a somewhat 
flimsy tripod. However, I've never experienced a vibration problem. I 
use a big tripod and push down firmly on the camera when shooting at 
those speeds. Handheld at 1/250 or 1/125, the camera is perfect. I've 
even had success handholding at 1/60 and 1/30.

format he says: "Mirror slap becomes a real problem as compared to 
most 66/645's"
As I understood the 67II should also have a mechanism that holds the 
mirror up if
you want it to. So where's the big problem anyhow?
