I've been waiting for a m4/3 camera with focus peaking and all of a sudden Olympus and Panasonic bring them out onto the market. Which one I'll go for is uncertain but I will buy one just for these lenses. If anyone is interested in these manual focus lenses I can highly recomment the Voigtländer lenses (made by Cosina) because they offer a lot and the price is right. Build quality is very high and they really shine on these modern cameras. You can buy some very cheap legacy lenses from all manufacturers (present and past) but I like to know what I'm going to get. I'll spend a little more, but guaranteed the image quality is that much better.
Take a look at the composite above and tell me that you're not impressed by the image quality.
