Out of focus issue

Hi All,

Good Day!
Recently I'm trying to shoot a birthday party with kit 14-42mm, I realized that it was fantastic & accurate with extremely wide. But, too bad, when I take a zoom from 30-42mm (range) it was not able to focus or else hard to be focused!

Did you realized?

Still, after a while (switching between zoom & wide then AF, AF-C & M) it was not able to focus at all. It'll be back to normal again while took out the battery & re-insert again!

Why? Something goes wrong?

Re: Out of focus issue

I'm wondering if there is a physical problem with the lens focus mechanism because the contrast detect AF system is almost immune to the usual focus problems in DSLRs, like dirt or dust on the AF sensor. To eliminate the possibility, can you try the lens on another camera and vice versa.

Re: Out of focus issue

Switching focus methods while shooting in iA mode may confuse the camera, as it always shoots with AF in iA mode.

Re: Out of focus issue

I was wondering about the light level. Were these photos taken indoors, in relatively dim light? The focusing issues seemed to happen at the long end of the zoom range. At longer focal lengths, the aperture of the kit zoom gets as small as f/5.6, so the camera may not have had enough light to focus.
