3.1 Photographing with M42 / Minolta AF lens reduction
[Author(s): Petr Holub.]
Needs more testing!!!
Tested in following setup:
Date: 2002–08–13 20:30–23:30. Place: Flamenco concert, Brno, CZ
Minolta Dynax 600si
Russian mirror lens: 500/6.3 – 3M-6A (or ZM-BA – Russian alphabet???) N840247 with M42
M42/ Minolta AF lens reduction
Fuji Superia 1600 (with 4
th
layer) pushed to 3200ASA
Testing showed that metering doesn’t work correctly. System tends to underexpose at least 1 EV. Also
working conditions during this experiment were difficult because of overall low-light situation (correct
exposition was about 5.6/20 with 3200 ASA film!) and strong spotlight.
After that I tried to play with it using different metering modes and comparing results to the ones
measured through the standard lens I use (24–85/3.5–4.5 and 70–210/3.5-4.5)but without actually shooting
on the film. I’ve found the measurements through the M42 reduction generally not very reliable (in all
three modes average, expert, and spot) with tendency to underexpose which matches experiences from
the flamenco concert. To get proper exposure I suggest using either other light measurement (through other
lens or using external exposure meter) or bracket 0 5 through 2 5.
It should be tested more thoroughly, especially influence of different metering modes and the results
should be shot on slide film to get precise results.
3.1.1 Comment on M42
[Author(s): Magnus Wedberg.]
My own testing indicates that using M42 lenses on Minolta bodies is somewhat hit-and-miss. Results seems
to heavily depend on which lens you are using, and on the camera, too. I never use any compensation with
my Super Takumar 55/2.
