Used Soligor Spot Sensor II

[alnegri]

Hi.
I bought a used Soligor Spot Sensor II.
The question is: does it change the EV read, if I change the ISO to work properly?
In other words: I set ISO 100 and I read 9 EV on the 18% gray Kodak . If I change the ISO to 200 does the same gray have to change the EV to work fine?
Thanks in advance.

The rings around the lens does all the work. When you move the setting from 100 to 200 it moves the fstop one stop to the right. Then when you take a reading you move the outer ring so the ev rating aligns with the little dot at the top of the lens. Then you read of off the lines of exposure times and fstops to pick a set that will give you what you want, Fastest speed or max depth of field. You can get a ZONE guage from Calumet that wraps around the front of the lens with the middle of Zone V being on the little dot. It is very usefull if your into the zone system.
