    Hi everyone, i will get an om10. While i love the size and the quality of the panasonic 20mm, i mostly use my gear to photograph my kids indoors, and my mark I was frustratingly slow (searching) in low light with my oly epm1. I switched to the nice oly 17mm but that one is rather big (in comparison).
    Would the new sensor and engine on the om10 make a difference or would I still have the slow focusing issue indoors?

    No. 20mm is a slow focusing lens with outdated external focusing mechanism.

    Yup, that's pretty much what I found.

    Waaaay back in the day, when there µ4/3 lens selection was bleak- it was fantastic, and it still is, but the amount of fast focusing and variety of lenses has really spoiled me. An internally focusing lens is pretty fantastic.

    I have to agree that 20 1.7 is one of the slowest focusing lens in m4/3 system, the successful rate to lock on energetic kids indoor is rather low. I would highly suggest using the 17 1.8 instead

    I love the photos I see here posted taken with the P20, but I know that I value fast focusing too much to buy one. I hear great things about the 17 and may try one at some point, but I think I prefer the 25mm focal length instead, so I bought the PL25. I'd suggest that or the new O25, but I know many prefer the 17mm focal length.

    The focus speed if it were mount on lumix gx7 not bad at all.

    It's a slow lens on my GF-2, it's a slow lens on my E-M1 (and was on my E-M5). I depends on your frame of reference, I guess, but for me it's annoying lethargic in anything but the brightest light, where it's merely acceptable, and even then only for relatively static subjects. It's a shame, because it's quite wonderful in terms of size and optical quality.
