Hi, I came across the above lens which can be used wit the GH3 in ETC mode, was wondering if it was likely to be able to 'resolve' a HD image (i.e. will the optics be high enough quality for HD?
This lens will not cover whole sensor so in ETC mode (FHD/25p) is would become the equivalent of a 24mm lens?

Will it resolve an HD image? Any lens will resolve no problem. The problem is the vignette since the lens may not cover the sensor, even with ETC mode. You can't use the wide end, but maybe mid-range to long tele will be OK. More a concern is the extra noise you get with EX Tele mode. And forget about high ISOs, you might get away with ISO 1600 but be prepared to use heavy noise reduction (and not in camera if you can help it).

is this a c mount lens? i have 3 that i use (one doesn't fit past the flange of the gh2) and they cost ~$15 each. i just shot some stills with a 25mm c mount cctv lens. they aren't the highest optical quality, but they're fun to mess around with. i haven't tried any of the 'higher end' tv/film lenses, so i can't speak for their quality.
these are the photos with the one lens, and i do have a video in the screening room forum with a couple c mount lenses. keep in mind most of these were shot wide open (~1.4) and when you stop it down, it gets a lot sharper
