The GB-101 hood, intended for the 35mm f/3.5 distagon, is almost identical. You need to put it alongside a GB-103 and look very closely to see the difference. Through the viewfinder, it does not cause vignetting at 17mm on the vario-sonnar, but I haven't taken a photograph with it to confirm absolutely that there is no vignetting. It is (very slightly) more common and affordable than the GB-103.

This is obviously intended as a reply to the previous topic "17-35mm lens hood", I've clicked on "new topic" instead of "reply". Embarassed

I couldn't find a GB-103, so I went for a GB-101.
It mounts perfectly well on the 17-35 and provides good protection of the front lens.
It does vignette at 17 when stopped down. It doesn't vignette in the corners but on the right and the left sides.
Until I can get a GB-103, I stick to this one and I just avoid shooting at 17mm when it is mounted (I would say that vignetting disappears beyond 18mm, which is not a big issue).
Could anyone help me finding a GB-103? If I can't get one, I will eventually shave my GB-101, which is a shame...
Thanks,
Jean-Jacques
