I have had the lens for about a week and took it out on a few walks. I use a blackrapid strap, to the camera hangs off to my side, with the lens pointed downward. I have always carried my 4/3 Olympus bodies/lenses this way, without issue. The 12-40mm lens hood (maybe other m4/3 lenses are like this too? This is my first) has two push buttons on the sides, but really only one is needed to release the hood. The slightest touch (go ahead and try) is given and that baby slides freely. A replacement hood is going to cost $50. This is going to be a huge problem for me on my summer hikes. Even if I don't use the blackrapid strap, I can see this coming off easily with just regular use. But really. this is supposed to be a rugged lens/body system. I don't know Why Olympus put a pinch lock on this, if only one slight tap is needed to release it. The second button is if you put your lens hood on the reverse way (it's not a true pinch release). Anyone have any modifications or solutions? I am thinking about drilling a tiny hole and inserting a pin. Problem is I need to remove and store that pin when I want to take off the hood.
