I'm shooting a school assignment with the PZ-1p, a SMCPA 24mm f/2.8 lens.
http://www.bdimitrov.de/kmp/lenses/primes/ultra-wide/A24f2.8.html
I have to take three photos "up close & personal" of 36 persons who I
don't know (not friends, not family, not fellow students ... strangers).
The assignment specifies FILM and off camera flash using a Vivitar 285HV
set to "yellow" (shoe mounted radio trigger & radio slave hotshoe). The
instructor states the Vivitar 285HV automatic exposure on "yellow" will
provide proper illumination for f/4.
The lens is at 'A', with the camera in hyper-manual mode with the
aperture set at f/4. Ambient light metered with a Sekonic L-408 & the
shutter speed set 1 stop faster than metered, i.e. meter reads f/4 @
1/30 sec, the shutter is set to 1/60 sec.
On the third roll of film (after 22nd subject), I used the DOF preview
button on the PZ-1p to see how much DOF I was getting. To my surprise,
when I pressed the DOF preview the lens stops all the way down to f/22.
Do you think the camera has been stopping down to f/22 during taking, or
is this an anomaly affecting only the DOF preview. The earliest I can
get the film processed is Monday.
Is that a problem with the lens, with the camera, or with the
combination of lens and camera?
And whoever was offering the PZ-1p a couple days ago, please email me
off list. Looks like I may be in the market. I might could use my LX or
K-1000, but I need the 1/250 sync speed.
In the meantime I've set the lens manually to f/4 and setting the
shutter speed using hyper-manual. I will shoot additional subjects to
back stop myself in case the first rolls turn out unusable.
