: If on Flashmatic, it does seem that the T 32 is a bit off the 28 setting
on
: the 35 RC but, I was assuming I would set the OM 35 RC in manual mode at a
: speed of 60, set the aperture in the camera to match any of the two
aperture
: values in the T32 when used in auto mode. This is the same we would do
using
: the T series on an OM 10.

: Should work, right?
Sure, but like I said - the GN's 32 and 28 are so close that the flashmatic
system could also be used. Remember the GN formula where the distance is
halved with every two F stops, so the difference in GN's of 4m quickly
shrinks when the lens is stopped down for shorter distances:
F GN32 GN28 (diff) GN20
-- ---- ---- ------ ----
F1 32m. 28m. (4m.) 20m.
F2 16m. 14m. (2m.) 10m.
F2.8 12m. 10.5m. (1.5m.) 7.5m.
F4 8m. 7m. (1m.) 5m.
F8 4m. 3.5m. (0.5m.) 2.5m.
F16 2m. 1.75m. (0.25m.) 1.25m.
F22 1.5m. 1.35m. (0.15m.) 0.9m.
F32 1m. 0.9m. (0.1m.) 0.6m.
This also learns that a flash with a GN of 20m. is really more appropiate
for the 35RC - it allows you to use the flash at the closest focusing
distance of 90cm at the smallest aperture of F22.
