Behoo - anyone uses this?


Recommended Posts

BEHOO and its brothers BOOWU and BELUN were available for a lot of time: I do not know exactly the timeframe, but surely from before WWII (1935?) to the end of Leica screw mount life (first years of the '60s), but similar devices were made also for Leica M series... different mounts and coding but still present in catalogs of '70.

 

There were times when fotocopy did not exist...they were a set of copying devices for fixed dimension of subjects:

 

BOOWU : DIN A4,A5,A6 format (pages, tipically)

BEHOO : ratios 1:1,5 1:2 , 1:3 referred to the leica format (i.e. 36x54, 48x72, 72x108 mm)

BELUN : fixed ratio of 1:1

 

BOOWU could use any 50mm lens, BEHOO and BELUN the 50 mm Elmar only

 

The BEHOO used 3 different extension rings for the lens, and the legs can be adjusted to cover the three formats mentioned above; they are extensible, with clamping screw collars and engraved with the three distances to be set on. I remember (have the BOOWU) the "V" index you mention... but cannot remember its function... maybe related to the positioning of the 4 legs in the proper screw hole on the collars...I seem to remember that when any leg is into its RIGHT hole, screwed into, the "V" is seen OUTSIDE of the covered area... but am not sure... a nice device but more for collection than use... even if surely it still works properly...

 

Surely a specific instruction leaflet existed... if you are lucky, can find some reproduction of it in some of the portals dedicated to old Leicas... good luck!

Luigi and JC, Thanks a lot!!!

 

I will try some photos with it, I'm very curious about this device - not for copies, but for close-ups (I saw a few photos, from an old leitz publication, just terrific using the behoo).

 

Anyway... Thanks!

I used this device to copy A4 & A3 color publications in the mid sixties with both a Leica 111 and an M3. The results were excellent at all times but in most cases I used out door daylight. Printing presented no problems with colour negative but I usually used slide film for projection purposes. It is possible to use the bayonet/screw adaptor for use on the M series but from memory I used a Summar lens.

Sorry to resurrect this, but I JC's link above seems no longer to work, and I also would like to find out what the "V" position on the BEHOO's ring is for. Many thanks for your help. :)

I have looked into some books:

Laney (Laney, Dennis, Leica Collector's Guide, Small Dole, 2005², p. 407 writes that the holes "V" are usable with the accessory lenses 2 and 3.

But the code of the apparatus for accessory lenses is BEVOR. Although it uses the same lens ring, I think, that other legs are used as with BEOON.

lens No.2 and camera lenst setted on 1 m, the leg on the upper mark covers a field of 14x21 cm²; lens 3 setted on infinity, the legs on the middle mark covers 11x16,5 cm² and set on 1 m it covers 8,7x13 cm, the legs on the lower mark.

Lens No. 2 for the Elmar is called ELPIK, for the Hektor HEPIK.

Lens No. 3 is called for the Elmar ELPET and for the Hektor HEPET

 

Yours sincerely

Thomas

Thank you very much, Thomas. Were these accessory lenses made by Leica, and if so which ones? I'm grateful for your help.

Al this is an extraction from the Leica Accessory Guide from J Laney hope it will help
