I have 2 new einsteins and a new CC, firmware up to date. Have a question.

If I select ALL on the CC and meter, for example, I get a F11.7. If I hold my Sekonic 358, I get a F14. Consistantly the CC meters brighter and if I use F11 on my camera, its over exposed. I assume I'm not understanding translating the .7 to something higher than F11?

f/11.7, for all practical purposes, is f/14. Issue resolved. Can't comment on your other question.

Regards,

Thanks David... can you tell me how I can translate that when I that on the CC?

.33 is 1/3 and .66 is 2/3. So if you have f/11' 3, you have 1/3 stop more than f/11. If your camera is set to 1/3 stop increments, you would set one click above f/11. If you meter f/11'6, you essentially have 2/3 more than f/11. Here you would click twice above f/11. You amy also see a difference between your two meters, depending on whether or not the Sekonic is set to 1/3, 1/2, or 1/10 stop increments.

Also, you may still see some overexposure in your camera as some (if not all) cameras fudge the ISO value to cause a little over exposure. Slight overexposure (or "exposing to the right") is an often used technique to help limit noise in an image.

perfect, thanks. I was hesitant about the CC, but the more I use it, the more I like it.

You can set your 358 up to read 1/10 stops as well with the dip sw in the battery compartment. I don't like to use the 1/3 stop readings as I know my whole stops but not my 1/3 stops without having to stop and think about it.

I have my cameras setup for 1/3 stops. I can quickly dial in the whole stop and add or subtract a third stop without much thought. I round out the decimal on the reading to the nearest third stop. IE: f/8.1 is f/8 - f/8.2 is f/8+1/3

With the new Einstiens, it's easy to tweak one tenth of a stop if your looking for exact whole stops. I was doing a table top shot and I couldn't believe how accurate the adjustments are or how consistent my readings were. It's very stable...
