i valued the qualtity of the video with the gs 150 more than the zoom with a single ccd chip. significantly better, brigter color and more clarity.
to me, the zoom on the 150 is more than adequate for my needs. zoom without quality = nada.
the hotshoe on the 150 also allows for more lighting indoors if needed and corrects the weakness of the 35 in that regard.
zeiss lens on the 150
built in lens cover on the 150
somewhat better quality stills on the 150.
150 appears to have a more solid feel or build to it though both camcorders are a lot similar apart from the ccd issue.
consistently better consumer reviews on the 150. reviews of the 35 appear to try to justify purchase, rationalizing or putting up with its weaknesses.
in fairness, 150 does not do a true widescreen, and a tripod is still a good idea at higher magnifications. the manual is crummy as with the 35, and apparently the warranty is not great with only three months labor and a year parts. i'm buying an extended warranty for the electronics because their are too many moving parts and the thing is delicate. it just seems like the wise thing to do.
gs 150 = 3 ccd and better quality overall. more bite for your buck in my view.
