Canon 70-200 IS equivalent for GH3

Hey guys!

Like many, I am really wanting to make the jump to the GH3 from my 60D. The lenses I have thus far-

Tamron 17-50 (Canon)
Canon 50 1.4
Canon 70-200 4 IS
Rokinon 85 1.4 (Nikon)
Tokina 11-16 (Nikon)

I am sure the 50 would not be hard to replace. Any recommendations on a replacement for the Tamron? (Or what would be the best adapter for it?)

My main question though is about the 70-200 IS. Contrary to people saying that you don't need IS for video, I have found many cases when I really enjoy using it. I recently shot this small doc in Japan and was loving having the option to be able to do quick zooms on the 70-200. I had on a monopod with one of the IS options on (can't remember which it was) but it worked quite well. Still able to move and do pans and tilts, have a handheld look, but also be smooth and jitter free at 140mm.

I know there are some canon to m4/3 adapters, but do any of you know if the IS would still work? And I have heard that using adapters doubles the focal length of some canon glass or something? Or is there an equivalent lens I could replace it with?

Thanks for the help guys,

Matt

No, the sensor is just different, it is a x2 of what is considered full frame. I would suggest reading up on m4/3 before you actually switch, its going to double the focal lengths of all your lenses you have.

Ah I see. Since it is x2 of full frame, it really wont be too different than aps-c then? Since I am used to shooting on aps-c, it will only be a minor difference, correct? I remember Landis posting a photo of a gh2 still and a 7D still and the difference seemed manageable.

Yeah Matt, I think you'd love a gh3. If you want to keep all your canon glass you could look into a red rock micro adapter. I found mine for 311 when they originally go for around 700ish. Also, one of my favorite lenses on the gh3 so far has been the canon 24-105L. Although its only f4 it kicks butt during the day and you can film almost anything with it

If you want to keep your 70-200 you could get either a redrock adapter(but the equivalent focal length will be different on a gh3) or you could get a metabones speedbooster adapter, this maintains IS, increases the lens speed by a stop, and reduces the focal length, so in a sense you'd have a 100mm-284mm lens(35mm equivalent) and on a canon apsc camera you'd have a ~112-320mm lens.

Speed booster also enables autofocus, but I hear it's shit, might be better with the future phase detect cameras but IDK.

or alternatively there's the 35-100.

This with the gh3 is supposed to be awesome, like usable continuous video AF
