The 20 F/1.7 is a relatively noisy lens, whatever the camera settings are <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='
' />. It is far less noisy than any Canon AFD lens I have ever used. AFAIK, it is purely caused by the AF motor, i.e, switching on and off, and moving when focusing. I was a bit worried about it right at the start, too, as it is the noisiest lens of the MFT lenses and adapted ones I own. I did try an Olympus FT 35 F/3.5 Maro with adapter once, and that was really noisy, compared to the 20 F/1.7 (and very slow to focus <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />).
However, one gets used to this very quickly, especially when seeing the results <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='
' />. So far, nobody ever made a comment about the noise the lens makes, BTW. I don't think it really is audible, or irritating, at subject distance.
Kind regards, Wim
