Sekonic Studio S

[artie_kraemer]

I was wondering if anyone knows where I can find a user manual for a

Sekonic Studio S light meter. I have gone to the Sekonic web site and

the manuals do not go back that far in the models. This particular

model was produced around the mid 50's. All I have to really find out

from the manual is how to calibrate the unit. I was told to cover the

dome in complete darkness and adjust the Zero screw in the back of

the unit. I had done that and tooka reading off an indoor light

source and compared it to a reading that was taken by a luna pro. the

luna pro's reading was approx 1/30 at f8 the reading my Sekonic took

was approx. 1/125 at f8. Obviously way off. If anyone can help PLEASE

get back to me. Maybe I should crack the lock off my wallet and buy a

brand new unit!! Thanks all!!

I�m assuming your meter is an older version of this present-day classic: http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=46889&is=REG

 

This is a selenium meter which does not require a battery. Two characteristics: it isn�t sensitive enough to read low light levels. Also, the selenium cell is sealed against its arch-enemy, moisture.

 

Your problem, therefore, may be that the interior light is too low for accuracy. Or it may be that the seal on the selenium cell has begun to leak, which is terminal for the meter.

 

My suggestion is to try calibrating it to the Sunny Sixteen Rule. Point the incident hemisphere at the noonday sun. It should read f16 with a shutter speed the inverse of the ASA setting (ie: Tri-X at 1/400th second).

 

Then again, it may be time to begin hinting to Santa in earnest about the above new model.

I forgot to mention: your calibration technique is indeed correct.

 

No two meters ever agreed on anything. But two stops is just a bit much. Half or 2/3 stop I would buy.

<p>I also have this light meter but I do not know to use it. I never heard of calibrating it. I do not know how to match the F stop to shutter speed, And there is no instruction manual. If anyone can help that would be great! (:</p>
