Enhanced live view AF for Olympus kit lenses

Optimal live view AF support enabled for 14-42 and 40-150 kit lenses

Thanks go to John Baker over at FTU's sibling site, The Olympus UK E-System User Group, for spotting that Olympus has released expected firmware updates for the 14-42 f/3.5-5.6 and 40-150 f/4-f/5.6 Olympus Digital Zuiko kit lenses.

The rise from v1.0 to v.1.1 only adds one feature and that's compatibility with Imager AF mode during live view. This is the optimal AF mode for continuous live view with bodies that support it, but the only Olympus body that does so far is the E-420.

We've had an E-420 for the last week, using a 14-42 with v1.1 firmware. Both it and the new 25mm pancake we also have work in Imager AF mode on the E-420. This means that contrast detect AF operates in live view mode and there is no need to refine the AF lock using phase detect just prior to exposure.

The E-420 will autofocus all other Four Thirds AF lenses in live view using contrast detection, but unlike Imager AF mode, final AF is determined by phase detect when the mirror drops down before being pulled back up for the actual exposure.

It's not yet known if any other existing E-System lenses can expect a similar upgrade.

We understand that the Imager AF mode compatible lenses will work with the Panasonic Lumix DMC L10's live view AF system, though this hasn't been verified. Please get in touch if you have been able to try this.
