Hallo liebe Mitglieder,

diese 12585 Gegenlichtblende in der Form (siehe Bild links) kann ich nirgendwo finden. Ist die Blende echt und aus welcher Zeit stammt sie?

Danke und viele Grüße

Frank

Hello dear members, this 12585 lens hood in the shape (see picture on the left) I can not find anywhere. Is the aperture real and what time does it come from? Thank you and best regards Frank

Besides the engravings, the back section which clips to the lens is the same on 12575 and 12585 hoods i suspect so that of a 12585 has been screwed on a 12575 i guess but i may be wrong. BTW those back sections can be unscrewed as shown by Andy Barton here:

The rightand one looks correct for the Hektor 135/4.5, Elmar 135/4.0 and 90 mm lenses of the era (1960ies)   The lefthand one indeed looks like cobbled together from a 12585 and some 135 mm lens hood.

Thank you for that information.


The ability to unscrew the hood could be an explanation, although I can't unscrew it now.
The hood is bigger than the 12575 and it works on the 50mm (35mm not tested).
I am now trying to find out which hood was screwed onto the 12858 adapter.

Many greetings

The 12575 hood and this faux 12585 will cause vignetting on 50mm let alone 35mm lenses. What's a 12858 adapter? Just curious.

A number twister. I meant the part of the 12858 that is attached to the lens. My wrong 12858 does not cause vignetting on the 50mm (Elmar).

I bought the hood together with an Elmarit 90mm LTM. Looked right at first glance. But it causes vignetting on the 90mm Elmarit.

I did not understand what 12858 is sorry but your hood should vignette on your Elmar 50 if it does on any Elmarit or Elmar 90 IMHO. I would check at f/16 or f/22 to be sure.

If it does, it should cause vignetting on your Elmar 50 as well, let alone on a 35 mm lens. This hood is much too long for a 50 mm lens. I suspect it may work well on a 135 mm lens.

I was also amazed, but the diameter of the front lens also plays a role. 
In the pictures this hood on an Elmar 50mm, Elmarit 90mm.

Vignetting is visible at the corners of your 50mm picture as well. On 90mm lenses the 12575 hood does not cause vignetting normally but the fact that your camera is not a Leica (Nikon?) may play a role.
