Here is a video that illustrates how manual focusing is done with the Panasonic Lumix GH1 camera. The Olympus 50mm f/2 macro lens is attached to the camera through the Panasonic DMW-MA1 adapter. The adapter is needed since the lens is a Four Thirds standard lens. No autofocus is possible with this combination.
When powering on the camera, it prompts you to switch to manual focus mode. This is not needed. You can leave the camera in autofocus mode, however, no autofocus is possible, of course.
Turning the focus dial will enable the zoomed view. What you see now is a 5x magnification of the centre of the image.
Tapping the shutter release gently brings up the normal full view again.
In the magnified focus assist view, you can use the front dial to switch between 5x and 10x magnification. You can also use the arrow buttons to move the magnified area around, in case you do not want to focus on the centre of the frame.
When you power down the camera, the lens will retract to infinity focus.
It would have been good to have a dedicated button to alter between the magnified focus assist view, and the normal view. While you can bring up the normal view by tapping the shutter release, turning the focus dial, which you may not always want to do. You could also use the focus area button on the rear, and then press OK, which brings up the zoomed view.
When using the Olympus 50mm on the GH1 are you able to adjust the aperture through your mount adapter?

ReplyDeleteThe Olympus 50mm Four Thirds lens works just as on a Four Thirds camera, EXCEPT for the autofocus. So the aperture works just like any other Four Thirds and Micro Four Thirds lenses.
Awesome, thanks for the info.
