4/3 adapters auto or manual

Hi All,

Is it worth paying the price for a Olympus MMF-1 OM 4/3 adapter at around 160 as opposed to the far cheaper non auto adapters on ebay from 8 - 20 for most legacy lenses, and if the latter which one of the numerous non auto adaptors would you recommend.


Regards

Gavin

Re: 4/3 adapters auto or manual

As I understand it there is no functional difference between the Olympus product and the cheaper clones. However the 'fit & finish' may be very different, I have no personal experience. I cannot justify the Oly version for the limited use of my legacy lenses.

Re: 4/3 adapters auto or manual

I have recently received my cheap import 4/3 to OM adapter with focus chip, and it works perfectly. I am really happy with it and might now purchase a few legacy lenses to play with.

Here's a set I posted recently, all taken with the OM50mm f1.8 lens and the el-cheapo Chinese 4/3 - OM adapter.

Re: 4/3 adapters auto or manual

I bought mine off Ebay (no chip) for around 12. Works perfectly OK.

So with this adaptor (^^^^) the E400 would still retain AF and it would AF the older lenses?

Hi Tim

No, the E400 won't auto focus with this adapter... what the focus chip will do is to confirm with the camera's beep and viewfinders confirmation indicator that the image is in focus once you have manually focussed the lens.

With any legacy lens placed on any of the e-series cameras, full manual is required, i.e. manual focus, manual exposure (shutter and aperture).

Shout if you need more detail.

Re: 4/3 adapters auto or manual

Thanks John,

I suppose this would be an excellent way into using manual settings alot more then.

On the exposure: you can set the camera to the Aperture prefered mode, and after focussing stop down and make the photo.
Works with my E410 and E520.

Aye, it certainly would be that!

To be honest Tim, it's not that bad is 'M' mode . The camera will still provide you with the metering settings, so you can adjust things easily enough. The thing is, there's no way for the lens to communicate its settings (aperture, focal length etc) with the camera, nor is there a motor in the lens which is used for the auto focus mechanism. The auto focus confirmation is just that... a confirmation that you have the center of what's in the viewfinder in focus.

You set the aperture manually on the lens by turning the dial, then tell the camera what the aperture is by (when in 'M' mode) setting the aperture in the camera to the value on the lens, then the metering system will tell you when the image will be correctly exposed - if you look in the viewfinder or on the display - you'll see the -ve or +ve indication which will point you in the right direction re shutter speed.

The good thing about the OM50mm f1.8 or f1.4 is the excellent bokeh and DoF. Have a little peek at the set I posted a link to in the thread above to see what I mean.

Re: 4/3 adapters auto or manual

I am really intrigued by this as it looks like you can get a wide variety of lenses in OM for very reasonable money.

So basically once the lens is set up by eye you then have to correspond the camera settings to match?

Yep, forgot to add that you can use this method as well, thanks Peter.

The only issue I see here is that when I have the OM50mm f1.8 on the E-3, though the lens will manually step to f1.8, the max aperture setting I can choose on the E3 shows f2.8... weird...!

So, if I use this aperture on the lens, and I am in 'A' mode, I have to compensate with -2ev i.e. f2.8 - f2 - f1.8 to get correct exposure.

Yep, that's the way. Use the cameras metering system to set the aperture and shutter according to your shot requirements.

Not with my E410/E520 !

If I use my 500mm mirror lens and Aperture prefered I just focus and take the photo. The camera determines the propper shutterspeed.

The same with the 1.8/50mm.......

Maybe the E3 differs in measuring from the E410/E520.....

To be complete: I use manual focus and Aperture prefered exposure.
