I was about to do some film speed testing, and thought I would compare my two light meters prior to doing so. I set up my gray card and metered with my Pentax spot meter. I got an EV of 7, and so a shutter speed of 15 secs at F/5.6.
My Sekonic digital meter showed an EV of 8.5, close to a 30 sec exposure at F/5.6. Other readings were similar, within 1 to 2 stops.
However, using the example I gave, I set the Sekonic to give me a shutter speed based on an F stop of 5.6, and it gave me 15 secs, what the Pentax gave me.
Can't think what I may be doing wrong. Perhaps the EV function on the sekonic is not functioning correctly?
