E300 and Nikon F lenses to 4/3 Olympus E-1 Adapter

Boris · Feb 20, 2005

Postman dropped off the Nikon F to 4/3 Olympus E-1 Adapter yesterday afternoon but had no chance to use it untill this morning.

Well machined black aluminum on the 4/3 end and a stainless steel Nikon F mount on the other...smooth installation...solid click...MF of course and stopped down metering... metering seems right on after a couple of hundered shots. My Nikon 500mm f4P focuses fine on the E300 screen...better than my S2. Got about 30% sharp images at iso 400 and wide open...on a mono pod....which is not bad.
I have many Nikon lenses so the $175 price tag is not so steep.

With these lenses, (attached with the converters), where you must manually focus, does the infocus light still light up, to let you know when the image is in focus, or do you also not have option to that?

Thanks & Regards

Adam.

I think that the infocus light doesn't light up when you MF with a 4/3 lens...

No in focus light but the E300 focusing screen is good.

Hi Boris,

What focussing screen? Are you talking about a split/focus screen, or a pyramid focus screen, or something I'm not aware of.

I can't see anything in my camera that helps me to focus, except for the little light.

As I don't trust my eyes, I'd prefer the light, or some sort of focussing screen. I wasn't aware that the E-300 had one.

Can you please comment...

Thanks & Regards

Adam.

When you see the image in focus on the screen it is in focus....you have to trust your eyes.

I'm still waiting for an adapter from Olympus so that I can use my OM lenses. I'm getting excited now!

It's my opinion that it would be possible for the "in focus" light to work with manual focus lenses, if Olympus would enable it with a firmware update.

It works while manually focusing a ZD lens. It also used to work with older autofocus cameras using manual lenses, Minolta’s I believe did this. You can easily test my theory by focusing your ZD lens on something close and then, without touching the focus ring, move the camera in and out a focus, when it's in focus the light lights up! The body uses contrast detection to determine focus. I don't believe that it has to be restricted to autofocus lens.

I believe that it would benefit Olympus to enable this "in focus" light. I think it would definitely influence possible customers that had legacy lenses, if they thought they could more easily use them with the E-system camera's. If we all wrote Olympus an e-mail asking for this to be enabled I think that we would all benefit. I think that it's possible that this is not a difficult firmware adjustment.

Think about how much easier it would be to use your legacy lenses, say at 5.6, if you had a "in focus" light.

I alsways wonder how that VR in the VR lenses, i.e. Nikon 80-400 VR works.

Do you simple need some power on some pins of the bajonett. VR should be independed from the body, so if you could get it to work if you add some power to the right pins and then attach it via adapter to the 4/3 mount you could have an image stabilised lens (still manual focus and stop down metering, you need that aperture ring on the lens!) but it would be an idea...

Someone who want to try ?

Zoltan2 · Feb 21, 2005

Hang on, is there such a converter for Minolta glass too?

You need to sent the CPU in the lens the proper unlock, start, stop, and lock messages. You'd need a small SPU to at least fake that part of the camera to lens dialogue.

A much more fun adapter would be 4/3 to Canon EF, with a small CPU. If anyone could ever get the "open" 4/3 spec, you could decode 4/3 messages, convert them to appropriate Canon messages, send them to the lens, receive the replies from the lens, convert the Canon messages back to 4/3, and send them on to the camera.

So - focusing detection is done by the camera, and not the lens?

Wierd then, that Olympus did not leave it this way, unless it's another marketing ploy, trying to get us to purchase 4/3rd lenses only.

From previous replies about firmware suggestions emailed to them, I think we've got buckleys of them changing the firmware. I think we've got more of a chance with a hacked firmware from Russie like happened with (Cannon, was it?)...

Cheers

It's theoretically possible, but Kindai isn't making one yet.

There are 6 adapters for 4/3 on the market. Nikon F, Exakta Lens, Olympus OM, Contax RTS, Leica R, and Pentax m42.

The Minolta registration (lens mount to film or sensor) distance is 44.6mm.

The registration distance for all the other mounts listed range from 44.7mm up to 47.0mm, so there isn't an adapter you can put on the Minolta glass which will then let you use any of the other Kindai adapters.

The adapter would actually have to be made for the Minolta mount.

Hi Adza

The e-300 should have the same type of focussing screen as the E-1 , when I received my E-300 the screen was missing & I returned it , the replacement was A-OK. The ist one was probaly a Friday afternoon camera.

Adza · Feb 21, 2005

Hi guys,

Is a focusing screen a visible screen, that tells you whether your camera is out of focus, or is a focusing screen something different?

It used to be a piece of ground glass exactly at the same distance from the lens as the sensor/film is.
Now it is some laser etched plastic, but it works the same way.

Adza · Feb 22, 2005

And it's supposed to be visible when I look through the viewfinder?

Which side of the view finder. At what position, and how does it tell me if I'm in focus or not?

Thanks & Regards

Adam.

Did you ever see one of those large format photographs, with a big wooden box on a tripod- they used ground glass to focus before they added the film....

The viefinder is visible-well actually it is all you are looking at- the crosing of the light beams, that would produce an image on the sensor- but this time you see it at exactly the same distance, but thrown by the mirror through a pentaprism or poro mirror-assamblance- the matte is needed to produce an image.

Hell, why do you own a dSLR- press the aperture preview button and you will love it even more- what you see is what you get-plus the DOF that you can preview with the button- optical P&S viewfinders are OK, as long as you don't focus to close- EVFs make me seasick after a while- at least the actual ones that hint after the actual view.
