The loudness or harshness of shutter sounds have been mentioned in quite a few posts recently and I was wondering if there is or has been a standard, a-bit like the CIPA Frames per Battery Charge idea? Maybe max dB @ 2m in front of the lens or somesuch? Should a lens even be fitted? I suppose no lens would 'level the playing field' and standardize the results between brands. Accurate sound meters are pretty cheap now....I almost feel like testing all of mine!
