To all k7 owners about mirror blackout times

I myself would like to upgrade from my k200d to a k7 or k5 but after
handeling last weekend a new 60D and D300s I really was impressed
with the speed of mirror blackout times of both cameras. The 60D
really impressed me all around but the up and down of the mirror
was so fast it sound like one click not 2 distict clicks that you can hear
with my k200 which now seems so slow.
So my question, is the k7 that fast with the mirror even down to a
1/5 sec?

In terms of practical photography, the performance criteria would be Single-shot mode shot-to-shot cycle time - the amount of time the camera forces you to wait until you can take the next shot.
If the mirror is back down a bit earlier, it helps with composition or eyeball tracking, I suppose, but you still have to wait to take the next shot.

There is, of course, no data available on the 60D, but there is for both the K-7 and the
60D's predecessor, the EOS 50D,

Imaging Resources timed the shot-to-shot cycle time for RAW shots -
K-7'- 0.26 seconds,
50D - 0.25 secs.

No significant difference.

never even noticed this to be hoenst - k7 the mirror seems to make very little impact on the length of the exposure

certainly with continous shooting at 5fps the mirror is down enough for me to continue tracking things in the viewfinder with ease with a shutter speed of about 200-500th of a second- longer exposures obviously gonna have the mirror up more but dont think its a big percentage of the time except if you compare it to very very fast shutter speeds
