>"possible to use the Canon lenses on the Pansonic."
Yes, it's possible to use them, but:
1) you'll need to buy an aftermarket adapter. (~$30)
2) they will be manual focus only.
3) the only way for you to set aperture will be to mount the lens on the Rebel, set aperture, take the lens off the Rebel, put it on (the aforementioned adapter, and put that on) the GF1.
There's at least one company working on an electronic adapter (which will enable auto-focus and aperture control) but pricing hasn't been announced (and could be as much as $1,000, but will hopefully be half that).
>"a mid priced fish eye lens with 8mm for the GF1?"
Lens selection is a big issue for the m4/3 format right now. So you either have to shell out $800 for the Pany or deal with manual operation of a third party lens. (Oly has one that's around $100 cheaper, but don't forget to add the cost of an adapter.)
My son wants to but the above camera body. He likes it as he wants to use it for taking video while snowboarding. We have a Canon EOS Rebel digital camera and am curious if it is possible to use the Canon lenses on the Pansonic. Also, do any of you have suggestions as to a mid priced fish eye lens with 8mm for the GF1??? Any thoughts on this will be so appreciated!!!
