    I am new to photography and this is my first camera. My bro has a full DSLR and was playing around with my G3 the other day and when in manual mode, he says altering -/+ EV can't be done. Aperture and shutter speed can be altered. On his, all 3 functions can be altered. Is this the case on G3's or is my camera faulty?

    You can't adjust EV compensation in manual mode on any camera, because the camera has no control over the exposure anyway. In Aperture or Shutter priority mode, exposure compensation will be available.

    I believe your brother is right. The principle is that when you're in manual mode, you have full control of aperture and shutter speed; if you want to make some EV adjustment, you directly modify aperture or shutter speed. If there were an EV +/- adjustment function, which parameter would it adjust preferentially?

    He is right about not being able to alter the exposure compensation. You are practivally changing the EV through one of the main parameters - shutter speed and aperture.

    It might appear that he's changing the EV compensation on his because the button you press to switch between shutter speed and aperture adjustment in M is the same as the EV -/+ in A or S. But in reality there are only two parameters that you can alter on the DSLR as well.

    If you're not convinced, just try to figure out what is the third parameter that gets adjusted on the DSLR.

    My guess is that on his camera, the EV adjustment doesn't change any settings - just makes the meter reflect the exposure compensation.

    With the way our meter displays the info, I don't see why you would need this.

    On my Canon EOS 350D it changes the aperture when I have the EV comp pressed. You have to use it since the camera doesn't have 2 wheels to adjust SS and Aperture in M.
