Fuji GF670 shutter speed handheld

[flatulent1]

Hi all,
I just fished a Fuji GF670 out of the 'bay. Lovely camera, I'm going to enjoy this thing immensely.

My question is about the slowest reasonable shutter speed one can use when shooting this camera handheld. I know the rule of thumb in 35mm is the inverse of the focal length or faster. But there are always mitigating factors; in this case, 6x7 format, leaf shutter, 80mm lens. Does the same rule apply here? Thanks.

I often hand hold 66 folders and 35mm folders and other R/F cameras with leaf shutters down to 1/2 second without problems

1/15 would be about the limit.

Yep, 1/15 on a good day (no coffee) w/ no wind and good technique. In all likelihood 1/30 is going to be more realistic.
