Not tried it with the 60d before would be curious to find out, from what I remember the older, wider focal lengths and the Ekran super speeds travel quite far back into the camera body but the newer ones are much better, I have a standard speed 50mm and a 75mm but they are in the shop being re-mounted. The 22mm is great and gives a really good standard field of view on the GH2 and is sharp wide open. Tried the 10mm a while back thats T2.8 I think, gives good field of view on GH2 but is more of an extreme lens and slightly soft, could have been the example I had and the fact it was older than the set I own.
