I feel this thread may be a thinly-disguised party for bashing
the Pentax 67.
If so, some basic truths must be revealed.
First of all, you should know that the Pentax 67 was never
designed as an actual camera for shooting: it was a display
device to be hung out in front of camera stores, over the
sidewalk. The first photographer to actually cock and fire one
noticed that, though his hair had turned white from the
shockwave, his sinuses had instantly cleared. After the hernia
operation, he used his Pentax 67 constantly, especially at the
onset of a cold or flu.
Body-builders were also attracted to the Pentax 67. They didn't
care that portraits from these cameras always showed people who
looked wide-eyed and startled, as if they had been recently
frightened by a loud noise. These cameras were great for pumped
and ripped upper-bodies.
Press photogs cherished their P67's when covering hurricanes and
tidal waves: they'd shoot with their Nikons and lash themselves
to their Pentaxes! But I digress.
You asked about the kerplunk, er kachunk, eh? Well, long, long
ago, before "red eye" was a problem for flash photographers,
Pentax 67 shooters were coping with the problem of "red EAR":
Color portraits and candids shot with Pentax 67's showed subjects
with crimson ears from the repeated auditory abuse they suffered
each time the camera was fired.
By the way, rumor has it that Pentax is currently
researching a solution based on existing red-eye reduction
technology (a series of quick pre-flashes before the real
flash fires).
The new Pentax 67 may include new red-EAR reduction
technology, which slams a heavy screen door a few times
before the actual exposure, to numb the subjects' ears
immediately before the shutter actually trips.
The other problem directly attributable to the impact of the
Pentax 67 mirror-return, is a type of focus blur. After the
shutter-release is tripped, the sonic boom begins advancing from
the camera toward the subject at mach 1. The wave-front reaches
the subjects just as the shutter opens, and the subjects are
knocked backwards, sometimes by mere millimeters, sometimes by a
zipcode or two.
Consequently, Pentax 67 lenses have an extra focusing mark
on their focusing-rings, similar to the "infra-red focus"
mark on other lenses.
This SSR pre-focus mark ("Sonic Subject Relocation")
predicts the focus for the spot where the subjects will
come to rest after the blast. It is to be used only when
shooting the P67 in small unmuffled rooms.
