1Ds3 Changes on Canon USA Website

Focus&recompose not only shift DOF, but also makes light and flash metering invalid.

I have moved the AF-ON functionality to the rear AF button on my cameras. Hitting the 1st shutter stage then will only meter. --> hit AF to focus, recompose if necessary, use the shutter to meter & shoot. For MF lenses w/ focus confirmation I usually move it back, easier to focus the lens while holding the shutter than the AF button.

Thanks for demonstrating my point.
Metering is now biased towards the area of the center point instead of the intended focus of attention. May Lady Luck smile upon you...

My cameras also have an AE/FE Lock button right next to the AF button in addition to the half shutter press that will lock exposure. And different metering modes. What else do you need ?

The capability to meter the composition of the actual shot, preferable at the time I take the picture.
As well as not to fall victim to the focus shifts associated with recomposition.
