Many thanks for taking the time to take those shots, most helpful

I'm fairly sure that they're completely different designs. The Olympus lens is specifically designed from scratch for m4/3rds (shorter distance from mount to sensor) and for fast CDAF - with lightweight focusing elements.

I'm not too keen on OLY designing similar lenses as Panny since we need more and different lenses, but I think they realized, from a market perspective, that a cheaper option to the Panny needed to exist in the market.

Brian,

How quick does this lens focus in comparison to the collapsable zoom? Is it faster than the 4/3 40-150 with the adapter?
Comparable to the Lumix 14-45... very fast, in fact the Pen focuses so fast with the mZD 14-150 and mZD 9-18, I'm happy to shoot with CDAF allocated to the shutter (usually, I have it separated on the AEL/AFL button)

Cheers

Brian

I've looked at this several times. The wideangle and middle part of the zoom I can accept, but the long end has some horrible decentering. I think more samples need to get out there to see if this is a QC issue or not. One of Brian's images I think exhibited some corner wierdness..not sure if its from lens decentering or not.

Some more samples from today - especially to answer the question of whether the lens is sharp at full zoom... these images are developed from raw using the free Olympus Viewer 2 converter - no sharpening other than scaling for web using Lightzone.

Yes, and I made sure I switched off IS this time... I need to do some more shooting at 14mm to see what's happening.

Cheers

Brian, thanks for posting these! These look better than some of the test shots we've seen (of course, they're also much better photos, for the most part), and they're much better than what I expected based on the SLR Gear tests. Perhaps I'll put the lens back on my wish list...

Obviously, it's difficult to convey how sharp this lens is at full zoom in these scaled down images - all I can say is that the full size images are very impressive.

Here's a crop to illustrate...

Some more wide / mid range examples from this morning.

These are all processed from raw using the free Olympus Viewer software... no CA correction applied, no sharpening other than scaling for web.

This is an interesting image - it shows the quality at 14mm, where I think the lens is at its' weakest... this is as much a test of my raw converter workflow, in dealing with distortion and CA - I would be very interested to see how much better you can do using your own raw workflow.

I have uploaded the raw file here, and would appreciate you posting your own conversion with some crops to show 1:1 detail as I have done below :
