Just received the Canon EF to M4/3 adapter so had to have a go out of the bathroom window. Manual focus and full aperture of course but with the MF assist of the E-M5 and the very good full aperture IQ of the 400mm the results are quite useful - especially as there isn't a 400mm prime in the Olympus line-up.

David, is this lens 400 35m equivalent or 800 ? sorry if its a stupid Q but just wondering ... as Oly lenses are effectively double :)

Very good results! I suppose the shorter flange to sensor distance of M4/3rds opens up more possibilities for adapting lenses from other systems.

I'm wondering how diddy the E-M5 would look on the back of a 400mm f/2.8L :)

Cheers,

800mm so quite useful.

Yes of course but only if the lenses have a mechanical focus ring. I have a friend who has a 500mm f4 so I'll give it a try!

More experience with this combination, this time with Kenko 300 1.4x TC:

That first looks REAL SHARP with this combo :)

Have your tried the Zuiko 300 2.8 on the m 4/3 ?

Very interesting. How is aperture control achieved?

Yes and I didn't get on with the spasmodically inaccurate AF. To use this lens as a MF lens only seemed a waste and it made horrible rattling noises with a TC14 (not recommended by Olympus). The Canon has better reach and IMO slightly better IQ, is 1/6th of the price of the Olympus, and it takes a TC without any serious issues. OK there is no aperture control but IQ is superb wide open, using it handheld means using max. aperture to achieve a high shutter speed so the lack of control doesn't concern me, although adapters are available with built in non-auto aperture control.
