    I'm seriously considering selling a few things to get the money to buy one of these Canons. Anyone have any experience shooting these lenses with Olympus u43?

    I've not used them on micro 4/3, but the Canon 75-300mm is a cheap lens that's cheap for a reason - it's supposed to be rather poor.
    The 100-400mm is pretty good but a very expensive lens to buy for micro 4/3. You'll lose auto focus and IS and, as with all Canon EF lenses, you'll only be able to use the lens wide open. You'd be much better off buying the Olympus 75-300mm or Panasonic 100-300mm IMHO.

    Well, not on u43, but I've used both on Canon FF. The 75-300 is not as good in IQ as the 100-400 - by quite a margin. OTOH, the 100-400 is BIG and HEAVY. Even on a 5dII it dwarfs the camera. Its IQ is OK, but TBH, it's not what I'd call stellar (a term I'd use with the Oly 75, or the Canon 70-200 f4 IS).

    I've got a Panasonic 100-300 now and I'd say the IQ is similar to the 100-400. Maybe a tad softer at 300, but it's close. It's also lighter, has AF, good OIS and you could buy almost three of them for the price of the 100-400! Nuff said!

    I'm still deciding between the 100-300 panny and the 75-300 oly.
    Good reasons for both.

    Yes....I forgot about the lack of aperture control on the newer style Canon Lens as well. I'm tempted to get the 100-300 Pany bt wanted more than 300mm of reach. I guess I'll have to wait for that manual f2.8 300 to show up in a reasonable price range that I can put a TC on.

    I own a 100-400, and have used it for years on a Canon 10D. I really love the lens, and it is probably the main reason I won't sell my Canon gear. The 100-400 image quality, IMHO, is excellent. However, it is big and heavy, and I generally do not carry it in my bag when I'm walking around. It makes my shoulders hurt. With an adapter, you would be stuck at maximum aperture, which is f4.6 to f5.6. You would have to use it on a tripod for stability and on a m43 body, it would be pretty unwieldy. I think the lens could easily put enough strain on the lens mount to damage the camera if, for example, you let it hang from a strap attached to the m43 body.

    Thanks Phil... Yes the OMD pretty much becomes the attachment on any lens with its own tripod mount. Right now...it is sitting attached to a Tokina 150-500 which I would say is at least as big as your canon..:)
