This image shows the quality you get using this combination. The lens is great anyway but here I used the E-PL1 and I think the quality is simply astounding. Just a reminder, this lens gives you a magnification of 1:2 out of the box. You have to use the adapter for it to get a 1:1 magnification. Personally I haven't missed it and tend to use the lens as is.

This seagull was gliding by just off the cliff face. I think it's one of only a few BIFs I've taken with this combination. Not that the focus speed is slow, there are better lens/camera combinations for this sort of thing. But, it shows that shooting birds in flight is possible.

One from the PL 14-150 again on the L1. Taken in very bright conditions while of a walking holiday in the north of France. This lens is made for these conditions and performs very well indeed on the L1.

Talking about these Four Thirds lenses brings me back to another great Lens by the Panasonic-Leica partnership, the Vario-Elmar 14-150 f3.5-5.6. I think this lens coupled with the Panasonic L1 is one of the best camera/lens combinations I have ever used. Looking back through the images I have made with this combination makes me ask myself why I rarely use this combination these days. Well, if I had the time I would, but I'm a bit of a camera geek. I like using different cameras and lenses. The lens isn't all that fast and can only be used in good light. The high ISO performance of the L1 is also restricting. I don't think I've ever used the L1 over ISO 400. Todays cameras are much better in this respect and offers more situations where these cameras can be used.

I thought I would post an image from the 50 f2 macro lens when mounted on the olympus E-620 Four Thirds camera. Couls you have seen the difference between the former image and this one. Could you really tell which image came from which camera? I know I couldn't. Might not be too surprising seeing the cameras have the same sensor in them. I think this one shows what this lens can really do.

Another great Olympus macro lens is the 50 f2 for Four Third cameras. Without the adapter the lens is not a true macro lens, delivering 1:2 magnification out of the box. Although a bit slow in focusing it does produce great images. This image came from an Olympus E-P2 m4/3 camera mounted on the Panasonic adapter. Manual focus again because AF on this lens isn't all that fast either and it tends to hunt all over the place. Many say this is a classic lens, one of the best lenses ever made and I can believe it. Very sharp ans contrasty. 

Using Four Third lenses on m4/3 does work (the PL 14-150 is a good example) but some are not optimized for contrast detec focusing and performance is abysmal to say the least. This lens is an okay  performer on Four Third cameras, not brilliant, just okay. When shooting macro AF doesn't play a role for me and I focus manually with every macro lens I own. It's just as well because putting this on a m4/3 camera via a four thirds to m4/3 adapter doesn't enhance it's performance in any way. Takes nice images though.

As can be seen from this image, focusing is spot on. The eyes are sharp which is exactly where I focused. This is set at 214mm so not quite at 300mm yet.
This lens is worth every penny.
