I have a K-50. I have a Quantaray 70-300mm lens attached to it. The rig is on a tripod. I'm shooting some static test shots using tungsten light. I have the camera set on auto focus. I have the "Custom Image" set at 0.0 for all options. I have the white balance set for "tungsten." I have the program dial set at TaV. I have the shutter set for a 2 second delay. I have the ISO set for 200-800. I have the lens set at the "A" position on the aperture ring. I have the AE meter set for "Center Weighted."
I'm ready to shoot. I push the shutter release button half way down, the lens focuses on the subject. I then release the shutter release button and push the "Green Button." It indicates that I need a shutter speed of 1/180th of a second. The ISO indicator on the view screen begins to blink "200" and finally stops at "AUTO." I make the exposure and I get image #1 below.
I change the shutter speed manually to 1/80th and I get what I consider a good exposure, as shown in image #2 below.
My questions are:
1. Does the "Green Button" indeed decide what shutter speed is needed under the prevailing conditions?
2. If the answer to question #1 is "YES," then how do I reset the exposure values in the camera so that I don't have to continually adjust them contrary to
what the "Green Button" is telling me?
3. If I'm all washed up as to the true function of the "Green Button" is, then can someone clue me in?
Thanks for any help you guys/gals might be able to furnish this dullard!
