Leitz VALOO
Elmar hood with aperture adjustment
Leica lens hood for the 50mm Elmar 3.5 lens. This model: VALOO, is larger and heavier than a FISON hood however this one couples up to the tiny aperture adjustment lever on the Elmar, when you twist the end of the VALOO it adjusts the Elmar's aperture with ease and also provides aperture click stops.
While this hood detracts from the compactness that is associated with the collapsible Elmar, it makes checking setting the aperture and checking which aperture is set much easier. You can still use Leica G series (19mm) filters and A-36 clamp on filters with the VALOO.
