For $10, there are not going to be ANY electrical connections in the adapter. It's just a hunk of plastic that lets the lens mount. You will likely have to do full manual exposure, manual focus, manual zoom and you will lose much of the capability of both the lens and camera.
iirc there aren't any canon power zoom lenses so he'd have to manually zoom anyway.
for focus he's have to manually control it.
from what i'm reading the gf3 can still do autoexposure with adapted lenses (similar to canon in that regard) but with (obviously) no aperture control. just set to 'A' mode when using adapted lenses.
Hey what about this:

Does it allow auto focus? It definitely gives you aperture control. It looks cool!
that's kinda interesting but i wonder if it properly uses f-numbers? of course you'll start with a weird f-number because there's not going to be any way to properly match the adapter's blades to the rear of the lens. so you may have to do several clicks to get any effect and when you do you're at f/2.1 instead of a typical 1/3 or 1/2 stop. autoexposure would deal with it just fine though. if it doesn't use f-numbers to stop things down (and it might not), then there's really no way to reliably use it for manual exposure.
it's not going to autofocus as canon and panasonic use completely different signalling. i've only read of one adapter that actually converted the signals and that was contax autofocus lenses on canon bodies. for the most part its not worth the engineering effort because there's not much demand.
the canon 30-80 is a bit of a rubbish lens so unless you're really hard up for long lenses it's probably not worth doing. you *might* get better results just cropping down from your regular images. though you do get the benefit of only using the center part of the 30-80's image (which is the sharpest part of pretty much any lens).
at $60 that adapter's not worth putting on a 30-80. or, more accurately, the 30-80 isn't worth buying a $60 adapter to attempt to use.
Cool, thanks.
Is it true that by mounting a full sized Canon lens to my micro 4/3 camera it's going to effectively double my "zoom"?
as a fairly technical photo person i hate the term "zoom".
compared to your 42 mm lens the 80 mm long end of the canon will be ~2x "zoomed" but it will be exactly the same as a native 80 mm lens for the panasonic. so, it's not the fact that you're using a lens designed for a 35mm camera that doubles your "zoom," it's the fact that you're using a lens that's approximately twice as long.
