Panasonic Lumix DMC-G5

Hi all,I see that the review at Steve's Digicams reports that the G5 sometimes focussed on the background rather than the subject, particularly in low light.Have any users of the G5 come across the same problem? If so, how often is this a problem please?(I'd be interested to know before purchasing the G5.)Thanks

Want try some Macro photography and I am new to this.Should I get PL 45/2.8Oly 60/2.8Kenko extension tubes and use any of my present lensesThe PL 45mm is the most expensive of these 3 alternative but it has OIS that might be desireable together with my Panasonic G5. I also have the Oly 45/1.8 so it would make me own two lenes with same focal view which seems redundant.The Oly 60mm gives me a prime with a new focal length compared to my other primes and it is less expensive than the PL 45mm....

Is GH5 basically G5 plus pro video, or do they have significant differences for stills shooting?Thanks.

Curious, has anyone figured out yet why the G5 (and presumably the GH3) doesn't allow an ISO value higher than 1600 when using the e-shutter?

Will we ever see a full review of the Lumix G5 on dpreview? I thought it might have happened before Photokina but with all the cool new stuff announced and soon to be reviewed, I have my doubts.loucious
