Why should we even care if our camera shutter is loud or not? What is the benefit of a quiet shutter? Well, it all depends on your shooting style as to whether is makes a difference or not. Ok, that is not totally true. Let me say it this way, some people care, some people do not. Here are the issues as I see them, though.
Following a comment on a post of mine a few days ago, I have been thinking about shutter noise. I unashamedly like quiet and I really notice when a camera is not quiet, even though that statement is quite relative. I was all excited to see the Sony a900 (this is the camera that brought up the topic in the first place) in the store and I picked it up to give it a few test shots. Ergonomics, handling, buttons: good. Style: very Sony-ish, but I like it (I like it more than the other Sonys). Then, I pressed the shutter release. KER-PLUNCK! Holy cow! That sound alone would take lots of great features and a very low price for me to actually think about buying one.
