Zuiko OM system MF mount onto GFX flange was fabricated in the condition of establishing infinity focusing with its installed shortest fuselage.

Focusing performance is done by rotating zooming ring from installed position to extending to functional designed position, with so quick action, sometimes difficult to focus at the desired position, because the rotation of zoom ring is made with applying of focusing action. Irregular use increases fliction resistor. In short, all the group and element move when focusing.

This kind of out-law, distorted, crazy and unusual modification is worth doing to put a 7.20mm focal distance lens on the large format, 33x44.

As a matter for big surprize, Zuiko Digital Zoom 9~18 for Micro 4/3 is fully applicable on large format especially if 16:9 aspect ratio is set.

Remember here, no irreversible modification on the original Micro Four thirds bayonet flange mount at all.

Let's say it just interesting!
