No, this has nothing to do with the Karate Kid movie, but a difference that I only just realised that existed between Olympus and Panasonic zooms. If you're looking through the viewfinder, with an Olympus zoom, if you have the lens set to widest and then wish to zoom in, you turn the barrel anti-clockwise. With the Panasonic zooms, it's the complete opposite. Interestingly enough, Canon zooms work like Olympus zooms and Nikon zooms work like Panasonic zooms. The focus direction is also the same with Olympus and Canon, with Nikon being the opposite; however, I couldn't find a clear enough image of a Panasonic lens to tell me which way it focussed. It might be a relatively small issue, but it would annoy the hell out of me if I were using both brand zooms and always having to mentally adjust to different lenses. I wonder why Panasonic and Olympus went this way? Olympus just followed on from the 4/3 style, but Panasonic didn't really have too much reason other than to be different.
