12 - 60 Af/mf

Hi Has anyone else noticed that the manual focus ring on the 12-60 operates no matter what the setting and even when the camera is switched of, or have I had another senior moment? Worse still have I got a faulty lens I have 3 other Oly lenses 14-54, 40-150 and 70-300 on these the MF ring just spins freely unless you select MF on the camera.
Regards John

John,

Never thought to look until you raised the points above.

12-60mm lens Manual focus ring operates as you describe. However, if you carry out AF the MF ring is disengaged and AF is achieved. Try it by manually defocusing and then carry out AF. You can actually feel the disengagement of the ring.

70-300mm Lens. Manual focus is switchable on the lens. Tis switch engages/disengages the Manual focus ring. In the AF osition it spins freely as you describe.

I cannot speak for the other lens as they are with my son and his E500.

Hope the above helps.

Kind regards

PeterD

This is a feature of SWF lenses.

The 12/60 has mechanical focusing doesn't it? All the others are 'focus by wire'.

I wonder if this contributes to lost shots when auto focus has been achieved and the focus ring is slightly nudged and critical focus is lost.
