First of all, I'm delighted with my 5D3. But I'm curious whether anyone else has experienced the issue (maybe that's too strong a word) of the shutter release not having a firm detent at half-press. I've owned half a dozen Canons over the years and only the 5D3 seems to have a very sensitive shutter release; it's more like a progressive "spring" as opposed to the other cameras (even my new 7D2) having a noticeable "pause" at half-press. The Vello 3rd party battery grip even has a more pleasant sensation when trying to switch on the metering or wake the camera up. Is this unique to the 5D3? I shot a lot of accidental frames when I first bought it until I got used to the sensitivity.
