270 mm

It is certainly ironic that after praising the compactness and inconspicuousness of the E-P2 equipped with the Panasonic 20 mm pancake, the lenses I have used most on the camera so far have been... my old manual focus Zeisses! After the Distagon 35/2.8, I have now been trying out the Sonnar 135/2.8. I had converted it to K mount, but I never used it much on the K10D. But on the E-P2 the lens is equivalent to a very respectable focal length of 270 mm on a 35 mm film camera. So I converted it back to the original Contax mount and, using the C/Y to Micro 4/3 adapter, put it on the E-P2.

A 270 mm focal is not enough for a wildlife safari (400 mm would be the minimum, probably), but it's good enough for taking a few interesting shots at a zoo or a nature preserve, for instance. I think the photos in this post are a good example of that. They won't get me on National Geographic, but I'm quite proud of these first results.

I can't avoid thinking it is weird to have a camera that uses only a portion of the image produced by the lens. It seems like a terrible waste of high quality glass... But as long as the sensor's resolution is good, the 2x "magnification factor" one gets from the 4/3 system may actually be welcome.
