I have a 24mm aspheric lens, which I'm delighted with. However, there is a problem. My camera bag is quite loose (I want it that way), and the sides press against the buttons on the lens hood. As a result the hood falls off, exposing the lens to possible damage. I've emailed Leica about this, and they don't make a screw-in hood for it. Does anyone know of one by another maker, or is there a way to disable the buttons on the standard hood so that they cannot be accidentally pressed? It is the only design problem I've seen with Leica. I don't want to start using a lens-cap - too slow - or a filter - degradation of image. Thanks in advance for any suggestions!
