C 250/5.6 with TWO serial numbers...

[WAn]

Hello everybody!

 

 

I've recently bought quite old Sonnar 250/5.6 and tried to identify the lens age

using the utility at www.hasselbladhistorical.eu.

The problem that there are TWO serial numbers on the lens.

One is on the side of the barrel, close to the front: 1594800 (www says 1956)

Another one is on the back: 2911814 (www tells 1961).

How is it possible? Has the lens been produced in 1956 and later reassembled in

1961?

 

 

This is a silver (matte alluminium) version; single coating (no "T*" mark); no

DOF preview lever at all; the VXM selector and a synchro contact are present;

the focusing scale is in feets only, the min mark is 8.5 ft, but the lens

focuses a bit closer.

 

No marks inside the rear part of the lens.

 

Thanks

Sorry, I should have specified the category: it is Zeiss lens for Hasselblad of course...

Front cell from one lens, rear cell from another.

Dan, you think it was a "do it yourself" repair by a handicraftsman rather than by Zeiss/Hasselblad ?

Yes, it sounds like the lens was repaired years ago with parts from two different lenses.

David Odess on this board (get address from member's listing) would be able to tell you as

he specializes in 'blad repairs.)

ok, thanks gentlemen.

Now I know at least when the parts were manufactured :)

Lets hope that the homebrew repair has not spoiled the lens performance.

Will see soon.

Also an interesting point: according to http://www.hasselbladhistorical.eu/HS/HSTable.aspx

the leaf shutter in the lens (500-cameras) started in 1957.

The label on my beast results in 1956. So Zeiss seems to have started to manufacture the C-line a bit earlier.

The number you find on the backside of your lens is most likely the serial number of the

shutter . The early C-Lenses all had the shutter serial engraved .

I have a C PLANAR 2,8/80 which was produced in 1956 , (Nr.1594923) . The 500C was not

even on the market in 1956 . My C-PLANAR 2,8/80 has the number 2955871 engraved on

the back .

My more recent 2,8/80 C-lens from 1959 has only one serial number (2663548).

 

But to present another mystery: I have a 4,0/50 mm FLE CF-lens. Inside the barrel it has two stampings in red ink: K98 (translating to November 1989) and E09 (translating to Mai 1990).

Ulrik, take a look at the end of the page

http://www.hasselbladhistorical.eu/HT/HTDating.aspx

According the quote: "Early lenses sometimes are stamped more than once. The date of manufacture will most likely be represented by the earliest date found, while later dates may represent the times the lens had returned to the factory for a (major) repair"

your Distagon may have visited the factory for repair twice, Nov-89 and May-90.

 

 

Jurgen,

thanks for the idea. If so, then it could be that my lens wasn't rebuild at all :)
