Metal "bumper" dome lens hood with 46mm filter size. Designed originally for the Panasonic LUMIX G 20mm/F1.7 this accessory acts as a great protector attachment and shade for other lenses, such as the Leica 35 and 50 Summilux, 75mm Elmarit or 28mm Summicron.
The hood has an inner thread to accept 37mm filters.
A customer from Australia writes: "I have now tested the 'dome' hood for the Panasonic 20mm f1.7 with the new Panasonic 14mm lens, released with the GF2 (same 46mm filter ring). I did some sky and blank wall shots with the lens bare, then with the hood alone and finally with the hood and a 46mm B+W UV full thickness filter (not slim). I was concerned that the Panasonic body might have some in-camera lens correction for vignetting, so I did the test with my olympus E-P2 instead. I can see no vignetting from the hood at all, even with filter. There is a slight fall off in light toward the corners with this lens, as you would expect with a 14mm - but the hood makes no difference."
