I am very happy with my Panasonic/Leica 25mm f/1.4 lens, but many people have complained about the awkward lens hood that comes with the lens and can take up valuable space in a camera bag: Unfortunately, unlike the hoods for many lenses (such as the Olympus 12mm - but at least the 25mm lens comes with a hood for free!), this hood is not reversible, making it difficult to store effectively: However, I have devised a cunning plan. For anyone who has one of the Micro Four Thirds pancake lenses, this hood can be reversed over one of those lenses, meaning that one can store a pancake lens plus the hood in the same amount of space taken by the hood alone. (I tried this with the Panasonic 14mm f/2.5, but I expect that results will be similar with the other pancake lenses). Observe: The 14mm lens and the hood: Reversed (front): Reversed (rear): In the bag: Of course, the hood cannot be used with the pancake lenses, but storing it this way should make much more efficient space of one's bag.
