Nope, no change.Put the camera in manual mode. Set it to f/3.5, iso 400, shutter 1/60 and take a picture of a wall. Ramp the shutter up/down, take more pictures and see if the exposure goes up or down.
If it works as it should, it's a light metering issue. If not, it's a sensor gain issue.
Sent this thing off just before the 4th. Got an email that it was done and a tracking number.Got it back around Turkey Day, but it's a refurb so I'm not sure what the warranty is.
