This test was done in daylight. The camera is a Rolleiflex 2.8F type 4 White Face with the Xenotar lens. The Rolleiflex filter correction wheel was set to zero. The exposure meters were both set to ASA 200. The subject was a Kodak Gray Scale Neutral Test Card.
The camera was set up so that the meter only read the test card.
In this picture, the reflective exposure sphere of the Gossen meter is facing down (otherwise you could not see the exposure on the dial) The Gossen reading was taken from the same lens position as the Rollei. As you can clearly see, the exposure is identical.
This test was also duplicated with my Hasselblad PME TTL meter (which attaches to the Rollei.) Once again the exposure reading was identical.
I repeated this test outside in daylight, and the exposure readings were also identical.
This test is proof that if the Rollei meter is set up correctly, it's capable of producing results that equal that of a modern day digital meter. Of course, modern digital meters do have such things as spot metering, which the Rollei does not.
But all in all, this test was a pleasant surprise!
I repeated this test with my f3.5F type 5 White Face camera and the results were the same.
