I've been looking at some 135mm lenses of late and have aquired 3 or 4 to see which one works best on the Nex system. I'm pretty sure that these old legacy lenses behave differently on the m4/3 system. Using a lens on the Nex system doesn't necessarily mean that you get the same rendition on the m4/3 system. One lens might work on one system but not so well on the other. The way I see it at the moment the longer lenses work better on the m4/3 system and the shorter focal lengths work better on the Nex system. I'm going to have to test these lenses on both systems to see if my instincts are true or not. By longer focal lengths I'm talking about lenses of 90mm and upwards. I've now aquired all the lenses I need to do the tests, all I need now is time :-)

This is a nice portrait taken on the Olympus OM 135 f3.5 and the rendition is quite nice. One of the best in its class.
