Hi Doux and others
I've only just come across this thread (I think I must have been half asleep recently!). Anyway, Doux, I was interested to hear your Panasonic 100-300mm is dying. I have had 2 100-300mm lenses and both have developed the same problem - dust inside the lens barrel, which ultimately effects the focusing system. Panasonic replaced the first one under warranty and are saying they won't replace this second lens (only 1 year old) because it's just over 2 years since the original purchase. Essentially, there seems to be some weakness in the lens barrel seals, which, in my experience, breakdown over time. Anyway, I am now looking to replace/upgrade my system.
The new Olympus looks very appealing, Ron. Am I right in thinking you could use a Canon 300mm f4 prime on it with an adapter? Would the AF still work?
Also, Doux, it's good to hear the Olympus 75-300mm m4/3 is better these days as I may well go for that. I cannot afford another Panasonic 100-300mm which only lasts 8 months.
