Just bought this hood from eBay, the seller said it's for the lens from 35~80mm but not sure.

It has two parts design, collapsible.
It can fit in to the mount on the body and turn to suppose to lock? But it's too lose, don't know that's what it is or damaged.
Cause the paint wear, it's not smooth to pull the outer part out.
Any one knows about this hood?
What kind of lens it can be used?
I have the 50mm Sonnar so when I use it should I pull it out or just leave it close to the top of the lens.

Thanks in advance.

Vince is right about the Contax I, and it's used on the 35mm and 80mm lenses. Never really caught on, as I know of no other manufacturer that made one. And you still had to have one for the 50mm. Butkus has a brochure on his site that shows the accessories for the Contax I.

It´s an original Zeiss design intended for the collapsible Tessar 3.5 and 2.8.
As a hood, it works , but you mst align the rectangular opening before shooting, otherwise it will be of no help. This happens because the lens barrel rotates and so does the shade, getting in the light path. Because of this, it´s more a collector´s item than a usable shade. BTW, I guess you still can get a Hoya vented shade with a 40,5 mm thread which doesn´t get in the light path.

I remember a 35mm of the 40's I think that a hood when reversed was a protective lens cover... Very Clever I think..

You might be thinking of a Werra. Very interesting camera -- it had a ring around the lens that (when rotated) cocked the shutter and advanced the film. My favourite are the green ones!

Does look interesting, but I don't know how they expect you to adjust the aperture!

You had to take it off. Or stick a small finger though the front opening and shift the (non-clicking, non-linear) aperture by guesstimate. Photography was a lot slower and less precise back then.

There is no question of how to match a focal length - as it attaches to the outer bayonet, it can only be used with 50mm lenses, where the opening will match the image frame when fully extended and used with a collapsible (maybe Tessar only - it looked less out of place there). And it won't rotate - the outer bayonet does not move. But the front part does tend to get entangled with the lens, as it usually has bent - mine at least was from rather soft aluminium alloy.

I believe the Zeiss Ikon Ikonette (35mm camera) also had a reversible lens hood/protector like the Werra.

The Werra is an excellent camera.

Some of these older accessories look better on a shelf than trying to use them. I think this is one of them.

Thanks Sevo
I do think the same. It looks pretty cool but the hood attched to the camera is not very sturdy, I mean not clicked in position, so maybe it's just for collection.

Thanks for other's comments.
 
I have one but in three pieces. It will not work on 85/4 Triotar nor 35/2.8 Biogon as it will take up the external mount anyway. Good for all other internal mount lenses, i.e. 50mm only. A collector item, fit the look of my Contax I. Don't even think above using it as you will find it on the ground eventually.
