So I got me a nice little adapter and the lovely Canon EF 50mm f/1.8 II to go with it. What will de best way to proceed here? Any settings and such? I have never used a MF-lens before nor an adapter.

If I just mount it on the camera, will it be f/1.8 or can I make it, say, f/4.0 or higher? And if so, do I need a digital camera from Canon to do so?

Do you have a Canon camera to mount it on?

shoot on apt priority on a micro 4\3 body focus wide open with the mf assist and then stopdown to shooting f stop........ does your adapter have a moving ring? if so you can put it on chosen f stop and open to focus ...and stop down to shoot , either type of adapter works well

enjoy

Aperture on Canon EF lenses is electronically controlled.
There is yet a way to control the aperture on m4/3.
You have a fixed focal length, fixed aperture 50mm (100mm equivalent) lens on m4/3.
The only plausible way to stop down is to use a Canon camera with EF mount (film or digital), set to Aperture Priority mode, choose a f-number, press the DOF preview button, and unmount the lens while still pressing the button.
It's surely a tedious method but unfortunately, it's the only method available at this moment.

Best advice is take the 50mm EF lens back to the shop you bought it from and try to get a refund. Use the money to buy a nice old 50mm Manual focus lens, there are lots of them out there, then get the adapter. You could do it all for the price of the lens you already have.

My father got a Canon 7D and 400D so perhaps both are doable?

Need the EF-lens so I can use it with a Canon-house in the future. Getting a 550D or 500D soon.

Another question - will there still be an indication when I have focus on an object?

voyager · « **Reply #9 on:** September 06, 2010, 12:44:12 PM »

Yes that is built in to the camera, not the lens. You'll always get focus confirmation. You'll need your EF mount camera to change the aperture, like gareth said they are electronically controlled, there's no aperture ring.

Appreciate all answers, will post some testshots later today or tomorrow. Thank you again.

That's true for Pentax, but not for m4/3. You will not have focus confirmation. You can however use a magnified spot inside the picture frame in order to achieve perfect focus.

Oh right because of the contrast detect. Whoops!

adash · « **Reply #13 on:** September 07, 2010, 12:02:50 AM »

I envy Pentax users for the instant Focus confirmation.

And this is where I ask you how to enable that spot on my E-PL1?

adash · « **Reply #15 on:** September 07, 2010, 05:39:42 AM »

I only have E-P1, but it should be the same;
Press repeatedly INFO untill you reach a screen in which a green rectangle is displayed in the center of the screen. Then pressing OK will zoom your screen on that rectangle. You could (I supoose) change the zoom between 7x and 10x with the help of the two buttons up right. Focus your legacy prime and press OK to exit the zoomed view, compose and press the shutter release button in order to take a picture.
You can exit the "green rectangle" screen via the INFO button again.

I'm not sure I like to part where you dismount the optics while having the camera on

Can't that hurt anything?

No, it won't hurt anything (not that I've heard at least

) I have an EF-m4/3 adapter for my 50mm EF lens as well. The EF lenses are a real pain for use with m4/3. I say reserve that lens for low light use or if shallow DOF is required and use your kit zoom for everything else. (BTW: Use the vertical roller to switch between 7x and 10x zoom in magnification mode.)

No, it won't hurt anything. It's just not recommended for whatever reason Olympus wants to get itself out of trouble for.

Centauri27 · « **Reply #19 on:** September 08, 2010, 09:05:42 AM »

Olympus doesn't care if you fry your EOS body! AFAIK, Olympus doesn't "officially support" any of the m4/3 adapters except for their own 4/3-to-m4/3 and OM-to-m4/3 adapters. You're on your own with any of these other adapters. Having said this though, there's very little that can go wrong, unless you get a poorly made adapter that doesn't connect properly.
