Please help with Lens identification

[mkp]

I have some lenses that I would like to learn about....

what is Kreuznach, Symmar, symmar-s, xenotar, synchro, compur, angulon... also the last one was attached to a tube so I am thinking it may be a macro?

Are any of these lenses high end?

I have some 4x5 cameras and accessories that I may be selling at some point but before I let any thing go I would like to learn what I am dealing with first.

what is the equivalent 35mm focal length?

Thanks a lot !

Hi !

Compur is the registered brand name of the shutter. This a leaf (between-lens) shutter Made in Germany by Deckel-Compur in Munich until the end of the 1970s. Deckel Compur was a subsidiary of the Carl Zeiss group.
Syncho Compur denotes a compur shutter with a flash syncho socket.

Schneider-Kreuznach and Carl Meyer are registered brand names of German lens manufacturers.

Kreuznach is added to distinguish between numerous companies named Schneider in Germany.
Bad-Kreuznach is the German city in Rhineland where the main Schneider-Kreuznach factory is located.

>> Schneider – Kreuznach Symmar Synchro – Compur – P 1:5.6/135 1:12/235
Standard LF lens formula (6 elements / 4 groups) covering 70° designed for the 4"x5" format
>> (why are there 2 sets of numbers?)
This is a convertible lens; when you unscrew the font group from the shutter, you get a f/12- 235 mm lens, but with a much narrower image circle and degraded performance

>> Schneider – Kreuznach Symmar-s 5.6/300
same as previous but more recent, with improved performance and non convertible, designed for the 8"x10" format

>> Schneider – Kreuznach Symmar-s 5.6 / 150
same as previous for the 4"x5" format

>> Schneider – Kreuznach Symmar super angulon 1:8/75
wide-angle lens covering 100° of angle and just covering the 4"x5" format

>> Schneider – Kreuznach Xenotar 1:2.8/150
standard bright lens max aperture 2.8 for the 4"x5" format; formula (5/4); does not cover as much as a symmar but with outstanding results.

>> Synchro – Compur carl meyer near uv oa750 f2.8 5cm
Do not know this lens.

Thanks, Ian for correcting my mistake!
Hence, if I understand well, Carl Meyer is a fake German brand for the US market, just in between Carl Zeiss and Meyer Optik Görlitz

As no-one else seems to have noticed, I have asked the mod to move this to the right category!

Dude, have you thought of using Google or Ebay to find answers to some very, very basic questions? L

Pretty much so, could probably just as easily have been Hugo Zeiss instead of Carl Meyer Although that doesn't have such an authentic tone.

I wonder if Carl Meyer was a relative of Oscar Meyer?

RE: Carl Meyer lens name; about halfway down the page is an interesting explanation of the origin of the name.

FYI I have a couple of these lenses.
