Also, have you actully checked to see if the meter reading/mode is giving accuraty exposure results. You can use the Sunny 16 rule (on a sunny 16 day) to see if you get 1/200s in aperture priority at f16 and ISO 200.

"Sunny 16 day" is what?

... if you get 1/200 f16 iso200 shooting what exactly? Blue sky? Green gras? A red car standing in direct sun?

Meter off any neutral tone (zone 5)....Clear north sky about 60 degrees up, Gray stone, Average weathered wood, Middle gray (18% reflectance), green grass. Palm of your hand should be +1 EC on a sunny 16 day so set -1 EC in camera and see if you get the 1/200s or so.

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)
