    Hey guys,

    I was wondering if I set the IS correctly for my Voigtlander 25mm F/0.95 lens - should I set to 25mm or 50mm (as 2x crop factor)?

    I've set to 25mm all of this time and so far didn't notice any issue, but would love to get corrected if i'm wrong.

    Thanks.

    25mm. My E-P1 only has 24mm so that's what I use. Set using the lens focal length for correct IS.

    Always set it for the actual focal length, not some imaginary equivalent that belomgs to some other format.

    I don't find that the IS on my E-PL1 does much on legacy lenses so I usually turn it off. It does seem to work good with the native lenses though.

    Thanks for the input, but just to confirm this...
    I don't need to set the value for native lenses right? they're auto?

    No, you don't need it for lenses that communicate with the body electronically.

    For the record there are M4/3 lenses that don't communicate with the body like the Samyang 7.5mm fisheye or Lensbaby lenses that you DO have to set the IS focal length...againg the ACTUAL focal length.

    Same for the Voity previously mentioned - gotta set it up manually.

    I use legacy glass quite a bit and find IBIS on the E-P1 to be quite beneficial. I prefer ISO = 200 so shutter speeds can get long and IBIS extends that capability noticably.
