Hey guys, hoping someone can give me a bit of info on a dallmeyer 3inch f1.9 lens I picked up, it isn't marked with the super six inscription and I can't seem to find what the difference is between this and the super six variants, a super six has been a dream lens for me for many many years.

I've looked in the lens vademecum and it might be a petzval design and not a super six. I'll do a disassembly as it's an easy lens to take apart and have a look at the element design. Either way I'm still pretty pleased about it. |

Could you post some more photos of the rear section? And some side pictures.
Additionally looking through it with the aperture closed, to try and figure out "how far in" it is. |

I will do, I can pick up 4 reflections on the rear section but only 3 from the front making me think the front elements might be cemented together. I'll do a full break down tomorrow and post some pics. Not sure if this is a generation before the super six series, it is a complete aluminium body and construction. |

Not a Super Six, but a nice lens anyway. It's a cine lens with a limited image circle. _________________ Vintage lens aficionado |

many thanks for that, as far as I can tell it's the petzval design before the super six, the front section is on there very tight so I've decided against disassembly 😅 the image circle isn't too bad with the focusing helicoid removed, I think it'll cover a full frame body with vignetting, I'm going to figure out a non destructive conversion so I can use it on other bodies and see the output. |

At that speed, Dallmeyer made the "Cinematograph" Petzval. It could very well be this. |

It's not the Kinematograph, which was much earlier, but it may be a later adaptation or a similar design. _________________ Vintage lens aficionado |

The lens vernaculum has been the only reference 1 could come across.
"Dallmeyer Cine Lenses.
Dallmeyer's took a keen interest in the cine world and the shop in Mortimer St must have looked more like a
cine specialist than one now realizes. They were not just selling lenses but movie cameras, and were the UK
agent for the US maker Victor. (B.J.A. 1931, p324; 1934, p316) (But not in 1930?) And naturally, they sold
their lenses on the Victor bodies. There were also rewinders, Tripods, meters and all the accessories. In
B.J.A. 1928, p340 they summarize the wide range as from 1in to 24in and in apertures from f1.5. They then
covered 35mm and 16mm, with some 17 items for 16mm especially B&H Filmo, and 20 ultra rapid lenses and
22 telephoto lenses and almost as many projector lenses as well for 35mm.
The earliest noted was a f1.9 3in from a 1914 list- perhaps the fastest Petzval of the period though an f1.1
Petzval was made earlier. (It is not quite certain this f1.9 was actually a Petzval). A sample was noted at
No92,997 in a RPS historical article, and Dallmeyers dated it as "mid-1920's".(MCM Oct 1957). An advert. in
B.J.A. 1930, p749 lists f1.3, f1.5, f1.9, f2.9, f3.5, f4.5, and foci.
These were often telephotos in the longer version. Dallmeyer lenses were fitted on a range of cameras
including most UK makes and imported ones such as Victor (B.J.A. 1936, p317)
Shorter ones include the Triple Anastigmat and Triplar (Triplets) eg in 25, 50 and 75mm f2.9 (B.J.A. 1936
p315) on Ensign Simplex Pockette 16mm, as well as a:
Dallmeyer f0.99 In B.J.A. 1930, p352 this set a new limit, as a lens of 'gigantic aperture' for 16mm use in 1in
focus. It was in a focusing mount, with built-in hood, and the writer felt it was about as fast as could be
achieved- probably correctly. £20. There is no suggestion of the structure- it might possibly be an 8-glass
Gauss which would have just been historically possible by then.(?)
Dallmeyer f1.9 This was noted in B.J.A. 1927, p320 and was being mounted for the Bell & Howell Eymo. It
was then a well established product (ie. not the Super Six) being on the Filmo 16mm in 1926 and the Baby
Pathe (B.J.A. 1926, p336). It was also noted in B.J.A. 1930, p536. There may well be a change in optical
design at some time as the 6-glass Gauss may have replaced the unknown older design. Is this the first
Super Six in 1927 or 1930 or when? It was for 16mm, ie ?1in. and a set was available next year in 2-6in foci.
(B.J.A. 1931, p327)." |
