EOS Bodies - For Stills / Re: Overcoming the lack of Exposure control in Manual Mode 5D Mark III..ideas?« on: March 13, 2014, 09:16:56 AM »
Surely exposure compensation in manual mode is to offset the exposure using either shutter speed or aperture from the indicated 'correct' meter reading, in exactly the same say you perform 'exposure compensation' in either Av or Tv mode, except in those modes your EC is limited to either offsetting aperture or shutter speed depending on which mode you are using.
Or am I missing something ?
You're missing the third side of the exposure triangle – ISO. Auto ISO in M mode is a useful feature, only available on more recent bodies. It's my setup of choice for shooting birds in flight. Pick the aperture and shutter speed you need, and the camera gives you a metered exposure by altering the ISO. The v2 firmware for the 1DX added the ability to apply exposure compensation in that situation.
Ah, I see. Guess I'm stuck in the '70's Let's have a little Supertramp.
