View Full Version : Is this a LF lens ???

06-04-2011, 05:08 PM
I don't know anything about LF gear, but this lens came to my hands and looks very unnusual to a 35 mm / MF user.
Inscriptions : SOM BERTHIOT PARIS 1114862 FLOR 1:4,5 F=165
Manual diaphragm, from 4,5 to 32; no shutter, no focusing
Photos here

My search atempts disclosed two lenses for sale with the same references, but they look different from mine.
Is this a LF lens ? Has this model some variants - or are there parts missing in my lens ? Or could it be other kind of lens (enlarger, cine ??)...
Thank you in advance

I think it's an enlarger lens...

This thread looks helpful:


Note in particular threin the catalogue that Dan Fromm posted a link to:


In particular, this page from that catalogue which seems to indicate that the lens was intended for 10cm x 15cm:

Thank you all !
Matt -I had seen that catalogue but was still in doubt due to the differences in the barrel design (my lens and the drawing); but maybe that was some former version of the lens.

Best regards

It probably could be used for LF taking. I'm inclined to think it be an enlarger lens as it bears serious resemblance to my wollensak enlarging raptar 162/4.5, which was a lens for 4x5 enlarging.

Interesting. I have in hand a SOM Berthiot brochure from around 1950. It lists Flor enlarging lenses: 50/3.5, 75/4.5, 105/4.5, 135/4.5, 165/4.5 and 200/4.5. And it shows pictures of some of them.

It also mentions Flor taking lenses, shows pictures of 105/3.5 and 300/4.5, both in barrel.

The two types' barrels differ. The OP's lens looks like a taking lens, not like an enlarging lens. In fact, it looks much like my 135/6.8 Perigraphe Ser. VIb in barrel. I vote for taking lens.

I also have images of some pages of an SOM Berthiot catalog from around 1950. It lists a 165/4.5 Flor taking lens, for 10 cm x 15 cm. I vote for taking lens.

jp498, reasoning from one manufacturer to another rarely works well. Also, that a lens is in barrel doesn't mean that it has to be an enlarging lens. This is a typical ignorant ebay seller's mistake, and is how I once snagged a 135/5.6 Symmar in barrel for $32 delivered.
