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 !



Schneider – Kreuznach Symmar Synchro – Compur – P 1:5.6/135 1:12/235 (why are there 2 sets of numbers?)
Schneider – Kreuznach Symmar-s 5.6/300
Schneider – Kreuznach Symmar-s 5.6 / 150
Schneider – Kreuznach Symmar super angulon 1:8/75
Schneider – Kreuznach Xenotar 1:2.8/150
Synchro – Compur carl meyer near uv oa750 f2.8 5cm

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.

Carl Meyer was a US brand name used on lenses from various sources by B&J.

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 (http://www.zeiss.com) and Meyer Optik Görlitz (https://www.flickr.com/photos/43175600@N00/15339683708/) ;)

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 :D 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.

NOT TRUE. Lynn Jones shared this story MANY times OVER. Mr George Druker, the owner of B&J at the time was looking for a Germanic name for the war rep lenses and the lenses B&J designed. While Mr. Druker was w/ his wife @ her Dr appt. he took notice of her Doctors name, Dr "Karl Meyer". If you search the forum Lynn Jones had shared this story "many times" and that is according to the him.

BTW- Craig shared a link with the Lynn Jones B&J stories.

Lou, H. Lynn Jones did many good things but his memory wasn't good and he believed that repetition made falsehoods true. Witness his repeated insistence that Goerz American Optical Company was a division of American Optical Company.

Burke and James bought surplus and scrap lenses and scrap lens elements wherever they could, mounted as required, badged them as Carl Meyer and sold them. Some of the rebadges were quite good, for example, a Carl Meyer Sonnar that my late friend Charlie Barringer bought for pennies. Others were not, for example the Dagors B&J assembled from what others claim were scrapped elements.

The OP's Carl Meyer lens s/n OA750 fits EKCo date codes (OA decodes to 1953) but this could be a coincidence. Without more information I wouldn't blame the lens on Kodak.
