GH2 focus past infinity problem with AF lenses

[thomisus]

First of all, hi all.. I'm new to this forum and a pretty new GH2 user.


I have some 2 FD lenses ( 50mm 1.4 and 28mm 2.8 ), a 14mm pancake, a 45mm oly 1.8 and the kit 14-140mm.
I thought that it was normal for FD adapted lenses focus past infinity, but i discovered that turning on manual mode with AF lenses and turning focus ring all the way till the lcd focus slider is to the left give me out of focus images ( and video ). I can get good focus at about 3/4 of the slider to the left. This is really annoing in low light situations and night shots. The only fast way to get infinity focus is to turn off and then on the camera and the lens is resetted to infinity.


Is this a common issue with GH2 or should i take it to assistance?

Which make of lens adapter are you using?

I never really noticed it, but my 14-140 focuses past infinity on the GH2 as well - but not on the AF100. My 7-14, 25/1.4 and 12-35 both focus at infinity on both. Weird.

Legacy lenses focus where they should if you have good adapters.

This one http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=300602886638&ssPageName=ADME:X:RTQ:GB:1123 for FD. But as i said, i have problems with native AF m43 lenses like panasonic 14-140 and Olympus 45mm focusing past infinity in manual mode.

Anyone?

Sounds like your GH2 is faulty/malfunctioning. Still in warranty?

Yes.. I'll try to take it soon to local support.

Many still lenses focus past infinity so they can be used in extreme temperatures. Autofocus lenses are generally the worst offenders, but even some cine lenses do.
