Exposure Compensation

EV steps for exposure control is set at 1/3. When I press the exposure compensation button the control panel shows the full range of under and over exposure (-5 to +5). However when looking through the viewfinder, and scroll from -5 to +5 the marks that indicate 1/3 steps moves only to the left; i.e., underexposure. I was expecting the marks to move the right when I rotated the main control dial clockwise to indicate overexposure (moving towards +5). All experiments were conducted using the same aperture and speed. Am I using the 750 incorrectly or is this a camera defect?

I believe there's a menu setting that determine which things go when you spin the wheels...

It should be under the Controls Menu, and called "Reverse Indicators"

Well the Exposure Meter is supposed to move toward the left if reducing exposure and to the right if increasing exposure, like you see here:

If you have dialed in both your shutter speed and and aperture, then the only way EC can adjust your exposure is by adjusting the ISO. What mode are you shooting in (e.g. Program, Aperture Priority, Shutter Priority, etc.) and what sort of ISO settings do you have enabled?

I always us the manual mode. ISO sensitivity is 200; AUTO ISO sensitivity control is ON; Max sensitivity is 12800 and Min shutter speed is AUTO. Does this help?

Since what you are looking at is an exposure meter, what you see depends on your settings and light. So depending on what you set, it may never go to both extremes with exposure comp. In other words, if the settings and light give your meter a huge under or over exposure, the meter is going to be pegged one way or another no matter what you do with exposure comp. Use appropriate settings for the scene (and manual iso for simplicity) and you should see the full swing. If in A, S or P, the meter should be zero with a normal scene. Then adjust comp and watch the meter go either way. If in manual, adjust the settings for 0 on the meter, then play with the comp and you should see the meter go either way. You still could run into a wall, depending on settings and if the aperture has room to move to make the desired exposure.

Got it. Much appreciated.
