the Green Button Kludge and the DS2

[Aaron Reynolds]

Is the DS2 the only one of the new DSLRs that has changed the legendary 
Green Button Kludge?

I remember using a non-updated DS and hating how I had to meter with my 
old M lenses, but the DS2 behaves differently -- not perfect, but 
better.  Does the DS firmware upgrade add the same functionality to the 
DS?

With a non-A lens on the DS2, metering is activated by hitting DOF 
preview on the collar around the shutter button.  If you're in aperture 
priority, it sets the shutter speed.  If you're in manual mode, it 
tells you how many stops over or under you are.

It operates a lot like a Spotmatic with the addition of aperture 
priority.
