I am interested in the Olympus E-P5. It is important for me to find out how turning a dial wheel of the Olympus E-P5 when assigned to ISO works. With my current Canon G15, when I push the shutter half way down in Av aperture priority mode, the back screen shows the exposure aperture and shutter speed. When I turn the front dial for aperture the visible aperture and shutter on the screen changes as the aperture changes. But, when I want to change ISO, I have to tap the back wheel up, then the exposure disappears when the ISO band comes up, and I push left or right arrow or scroll the back wheel, then have to press the back wheel up again to select the ISO, but when the ISO band disappears, the exposure is gone, and I have to press the shutter halfway again. I can fool the camera by not selecting ISO and instead pressing the shutter button halfway, and then the ISO band disappears and I see a new exposure, but when the exposure disappears I am back to my ISO band because I did not actually select ISO. So I select ISO and go about taking the picture. I don't like this. I want when I dial wheel my ISO for the visible exposure to change just like when I dial wheel my aperture in Av and my shutter speed in Tv. With the Olympus E-P5, when I turn a dial wheel for ISO is the aperture and shutter exposure visible? When I stop turning the dial wheel for ISO does the ISO selection band disappear by itself, or do I have to push a selection button to select ISO, and when I do, does my previously showing exposure show up without having to press the shutter again? I would be willing to assign the movie button to exposure lock, if I need exposure to be locked to work how I want. I want to turn the aperture dial to set Av, flip the 1 2 switch over, then turn the front dial for for ISO, then turn the back dial for exposure compensation. How easy is all that? On another point and shoot I have when I press the back wheel left to get the flash settings, I keep pressing the back wheel left to then highlight the flash setting I want, and then all I have to do is wait a moment, and the camera selects the highlighted flash setting and the flash setting dialog disappears. I don't have to push "select". Does the E-P5 ISO work that way?
