hi guy...this is the first time I write here,but i read always this fantastic forum.I apologize for my bad english...but I never studied english! anyway I hope you understand me! I've always been curious about the reflex cameras with less mirror vibrations and which instead were the worst (i mean reflex cameras with very loud and noisy movement mirror mechanism).I know that the best choice,if you are searching no vibrations or at least less vibrations of the mirror mechanism, are the ragefinder cameras. But my intention is to catalog the reflexes in three categories: 1)camaras with no vibrations 2)cameras with some vibrations 3)cameras that vibrate too, so reflexes with a very noisy movement mechanism of the mirror. Do you want to start? Thanks.
