I checked the diaphragm and it seemed snappy.
Restored default factory settings.
Have been shooting in the aperture mode (Av) pretty much exclusively as well..
I thought what the problem initially was, was having it set to spot metering. I changed it to both center-weighted and multi-segment as well to see if it would fix it but I was primarily getting similar results with blown out images, and a strong tendency to overexpose everything.
Here's an example of what I get with the "proper" exposure as determined by the camera on the right. On the left is an image of the same place but underexposed almost as far as you can go that produced an image closer to what I actually see with my own eyes. Also, I got a better result when using spot metering, the other settings seemed to overexpose way too much in this particular situation
Data for the right image: F/2.2, 1/4 sec shutter, iso 1600, exposure bias 0 step
Data on the left: F/2.2, 1/15 sec shutter, iso 1600, exposure bias -2.3 step
Would shooting on shutter priority help, as that seemed to make the biggest difference?
Maybe its just an issue that i'll have to be more sensitive to when im in lower light, or brighter areas. It would be nice to not have to fiddle with settings so severely when shooting casually in jpeg mode though.
THanks for all the help so far!
