The "green button" operation of the -D is synonymous with hitting the AE button while in 'M' mode with a K lens. Basically:

- Put on a 'K' lens or an 'A' lens turned to other than 'A'
- Set knob to 'M'
- Turn aperture ring to desired f-stop
- (Manually stop down if using screwmount lens with K adapter)
- Compose and hit the AE button. The -DS will stop down, meter, and set shutter speed to the appropriate value. Note that ONLY center-weighed or spot mode are options... matrix will revert to CW.
- Any EV compensation you do by cranking the shutter speed up/down from the value just set.

There have been a lot of posts lately about matrix metering and K lenses on the *ist D and *ist D S that have left me bamboozled about what are the correct ways to meter with K lenses on the *ist D S. Since I don't have the *ist D the green button is an anomaly that doesn't concern me. I do have the *ist D S, and I would appreciate it if some kind soul would once more relate how one meters with K lenses on it.

MUCHO THANKS in advance!!!
