I am comparing the shutter sounds between two Canon 5D mark II's ...
The first camera is from January, is well used, and the shutter sounds fairly crisp, like a click. (Not as crisp as on the 1-series, but not bad.) The second camera is brand new and the shutter sounds springy or sproingy. I can actually feel the springiness causing a bit of extra vibration in the camera body.
I'm wondering why there is such a difference, and whether the new camera may be defective (or possibly improved?).
Does your 5D mk II shutter make a "click" or more of a "sproing"?
"Sproing" goes mine too. After trading in my 5D, I wondered if the shutter of my 5DII was sounding 'right'. Since I know the salesperson ( a professional photographer herself) she brought her own 5D and 5DII to me and we played shutter music. The 5DII both sounded the same and different from her 5D. It has been just over two months since I got my 5DII, works great, and the shutter sound is what it is.
