Thread: Difficulties focusing with 14-150 / E-P2 / Taking Videos

Hi!
I've just bough the Olympus m43 14-150 lens and of course immediately tryed it on my E-P2.

And to be honest: I'm not really happy with the autofocus especially during taking videos.

Especially using longer focal lengths >60 in-doors the camera often doesn't find the focus, searches the whole range and takes a lot of time, and sometimes simply does nothing. Even outdoor at pretty good light (sun shine) the camera sometimes misses to focus leaves taking videos at 150mm (ok there was some wind, but anyway). These problems occur when panning to the subject from a different subject especially when zooming in during video.

What is your experience?

I've though a lot about it, and I observed a second issue. When starting taking videos in better lit areas and panning into lower lit areas the picture get extremly dark. My guess is that the camera sets the aperture and iso when starting taking videos and this combination is fixed, so when the subject gets much darker, the camera cannot compensate any more.

And just when writing these lines I'm starting to think, if these two "problems" might be the same, since my experiences with the camera having problems to focus alway occured when panning to darker subjects (appart from the leaves in windy situations). I guess usually the camera uses high iso values _before_ taking pictures or starting videos to focus. But after having started taking videos, it cannot change the iso anymore (I'm not sure if it can change the aperture), and so if the subject gets darker, it fails to lighten up the subject but it also fails to focus. May I be corrrect?

Whats your experience?

Cheers,
