Was just trying out the sunny 16 rule with the kit lens on the NEX 7. It was mid-day and no clouds. So ISO 100 with 1/100 sec exposure and aperture of 16 was used. I'm concerned that I'm way too closed down f16. What would be the exposure if I was to use f8 or f11 instead.

I'm also concerned that I'm losing detail at f16 due to defraction. How do you adjust the sunny 16 rule so that you can keep the aperture you want? Each f stop up you 1/2 the exposure time?

Also, I guess the sunny 16 rule is a rough estimate and needs to be adjusted for the time of year and your latitude on earth among other things...

Any help is appreciated. I love having total control via manual mode and would love it if I could get he perfect exposure for a series of shots. Bracketing at +-1 EV is what I've done just in case at times..

F16 isn't optimal, just a starting point for that rule, to be adjusted for different apertures. You are needlessly complicating your photography life with this.

Aperture priority 'A mode' is the simplest, fastest, most reliable in most light - set & forget EV at or around 0, set your aperture for the 'look' you want (shallow depth of field, or not, etc), and the camera almost instantly calculates shutter speed to expose to EV=0 (use higher ISO in low light to keep shutter speed up if necessary) - almost point & shoot!
