    Was out with the 25mm on my E-M5 today and didn't notice the rattlesnake noise so I tried to generate it by pointing the camera towards the sun then away, to the sky, and anything else I could think of and it simply stayed silent. I never got the rattlesnake as bad with the E-M5 as I do with my E-P3 but I did get it and now nothing today.

    Anyone else noticing this?


    Spoke too soon. Just tried it indoors pointing the camera at a fluorescent light and I got the rattlesnake. Seems my outdoor success was simply good luck with the available light at the time (late afternoon).
  2. I find it to be not 100% rattle-proof but much, much better than it was on my E-PL1 and now my E-PM1. Most days it is silent even when trying to make it rattle in the same manner that you describe, yet occasionally I have heard it give a gentle rattle without any real apparent reason.

    Like others I find it to sometimes do it, sometimes not. More often than not, it will not rattlesnake.

    Either mine:

    a) Doesn't rattlesnake at all
    b) Or it does but since I don't shoot in total silence, I can't hear it

    I just got mine from B&H yesterday. Mine rattles randomly. It's loud but I forget all about it when I see the pictures taken with it.

    In my considered opinion, (which means I'm probably wrong), I have my OM-D on single AF most always because of my subjects, and my 25 hardly ever rattles. It seems a little worse on my E-PL3, but since I have the OM-D the Panny 20 is usually parked on the E-PL3.

    It has always sounded to me like it was searching for focus, why would it want to snap it's aperture blades open and shut? Does it think it's a castanet? Does it want to be held between some nice Latin ladies breasts? er... NM
