Should a Zuiko 40-150 + EC-14 + four-thirds-to-M43 adapter and Olympus (E-PM2) auto-focus?

Hi,

I already had a four-thirds-to-M43 adapter (this one: Amazon.com : Fotga AF Four Thirds M43 lens to Olympus Micro 4/3 Adapter replacement for DMW-MA1 MMF-1 MMF-2 MMF3 : Camera & Photo) and the four-thirds lenses that I have auto-focus all right.

So I just got an EC-14 today and tried it with my 40-150mm ZUIKO lens, and it did not want to focus automatically with my E-PM2.

I was surprised about this, and was wondering if this SHOULD HAVE worked?

Thanks,

Jim

Yes, it should have worked, but it might be rather slow to AF. Try cleaning the lens and lens mount contacts with a clean wipe (not with an eraser), or very sparing amount of DeOXIT if you have some.

BTW, I had somewhat spotty results with a 3rd party 4/3 to M43 adaptor. Sometimes it wouldn't make a good electrical connection. Cleaning the contacts and/or wiggling the adaptor and lens a little may help to establish contact.

FYI, I just tried my ZD 50-200 SWD w/EC-14 + Olympus MMF-3 adaptor on my PM2. AF worked better than I expected. A little bit slow, but it locked in. But, what an unbalanced and unsteady combination without some sort of tripod or monopod. I need to use that lens with an OMD so I can steady it for a shot.

You should take a close look at your adaptor.

Hi,

A couple of things:

- With the E-PM2, I have the red button (just to the right and above the LCD) set to magnify. When i press that button once, it puts up a green square, and when I press the second time, it magnifies. I guess this is mainly to help when doing manual focus, but can that also work with AF? What I mean is can I get the camera to auto-focus on the areas where the green square is? Or does it always AF on the center of the viewer? One reason for asking this is I had the camera on a tripod, and wanted the main subject to be more towards the upper left corner, so I wanted to focus on the upper left area, but have the center of the view be in a different area.

- Also, is there a way to make the area that it is trying to focus on smaller? I think the problem was that i was trying to take a picture where the subject was just a small area (like a skinny branch) but I think the camera kept trying to focus on the background.

I was messing around tonight in a more controlled situation, and it seemed like it was able to auto-focus ok.

Thanks,
Jim
