This FIKUS-copy [even better made than the original one] was offered by A.O. Roth to their customers - in both versions for either Leica or Contax.

Had the Leica-version for a long time but didn't know of the Contax-version until I saw it, massive brass and chrome, looks pretty good on a Contax II

Here is mine mounted on my If, the viewfinder is wonderful but rather ugly (only a mother could love it)

Test print (darkroom) from my Russar wide open at f5.6 look sharp. Leica 2f. I used a Leica 21mm finder.

The lens rear fits so close to the film plane that the spacing between the negatives has disappeared and the negatives touch each other.

I might have shown my lovely Agfa Isolate III before, but not with an image taken with it

Been busy recently doing various things, including getting ready to do a presentation in a 135 year old preserved darkroom next Tuesday. One of the items they have there is this 1880s/90s Lancaster Instantograph Quarter Plate camera  with a Thornton Pickard Time and Instant shutter and a Dallmeyer Rapid Rectilinear lens for 3 1/4 x 3 1/4 inch positive plates for projection with a Magic Lantern.  Back in the 1890s, the darkroom owner scratched the US/UK aperture scale on the lens beside the original Dallmeyer aperture scale. For the record 25 on the Dallmeyer scale = f15.81 and 50 is f22.36. I hope people here can see the f16 scratched near 25 on the Dallmeyer scale.  I have also enclosed, for reference, a chart showing the various aperture scales which were around at that time.

I have images which were taken with this set up which I will post at a later time. I also have the photographer's darkroom note books from the period 1888 to c 1920 which record that he used f16 for all copying and reproduction work. I will post much more about this when I get my talk next Tuesday out of the way. There are other interesting things in the darkroom including a possible 'solar camera' set up, which includes a window with a condenser lens embedded into it. A friend who is an eminent professor of optics is coming on Tuesday to give me his opinion on this.

See illustrations below which show how this would work for printing. Also shown is the window with a condenser lens, which fits the darkroom window.

Interesting @willeica - I have a similar lens - Dallmeyer Rapid Rectilinear, but marked "6x5" and "No 51362". It has an aperture scale 7.5 to 100, with 'normal' apertures 8 to 31 marked on the other side of the slot in marker pen. It came with my Gandolfi 4x5 (and is shown at minuscule size in my avatar). Somebody has carved (too deep to say scratched) "Ealing School of Photography" on the rear standard. I think this was a purely post-war institution (someone may correct me), so I suspect the Gandolfi and lens had a much longer history. I have used the Gandolfi quite a bit, but never the lens (I use other lenses with their own shutters).

I'm curious - where is the darkroom you will be giving the talk on? I visited the WW Winter studio in Derby a few months ago, which must have had a similar history from C19-C21.

Edit. I've just seen - Strokestown Park House

My Dallmeyer, for comparison.

Just tried to search the files in the Dallmeyer Archive for that serial number. Annoyingly it looks like the relevant pages have been hijacked by malware.

Paul, I will post some pages from the D'Agostini and Rose book tomorrow which may assist in tracing your lens. 6x5 was often a size for portraits. There are tables in the book which show a level of coverage for landscapes and a different smaller one for portraits or groups using the same lens.  I have no hesitation in posting pictures from that book here as the authors used a photo of mine without my permission. I am quoted in the Grubb section of the book as is our friend 'pgk'. Interestingly, a Dallmeyer lens with a diaphragm was an optional extra that one could pay for at one stage. There are tables in the book setting out the various options available.

Yes, my talk is in Strokestown House on Tuesday. There are many fascinating things there to discuss. I will do the talk again for PCCGB with David Gardner, John Marriage and John Wade and others in attendance. That should appear later on YouTube.

Here you are, Paul. I have put the pages in the same order as in the book. However the first one shows the catalogue for 1890 and the second one shows the catalogue for 1870. There are many options as regards size and specification etc. Note that the group /portrait coverage can be increased by stopping down for landscapes.

The item I found in the Strokestown Darkroom is the same type as the last one illustrated here, but much smaller. This is what Ivan Rose who co-authored the book told me about it last night. 

"The Dallmeyer RR, in that size it was intended for making magic lantern slides. That is the old Dallmeyer iris scale which can be confusing. Dallmeyer scale 25 is very close to f/16 (not to be confused with the US 'f' scale which is different again). This size is not listed in the catalogue for 1881 or 1896, the records have batches for 1883 starting No. 31733, 1884 starting No. 33840 and 1885 no. 35888, then in 1886 it seems to become the 4.25x3.25 inch size. So with that engraving it must have been a short lived size."

Have fun finding your one here.

Thanks, William - it looks most like the one in your third picture, with the 7.5-100 scale, though mine is engraved 6x5, and has a short hood (as shown in my photo). But this gives a good idea of the date at least.

Paul, the book can be regarded as a standard text. The Dallmeyer section runs to about 97 pages. I mainly bought the book for the Grubb section and I am mentioned a few times in the book.

A Sony A7II (R I think). Basically because the lens fits on an M bellows effectively clamped between the lens holder and Elmar Hood (this technique holds many lenses pretty well), and I can fit the M bellows onto the Sony with a Metabones adapter. Focus is over a wide range from infinity to closer than shown; its similar to using a 135mm with close focus! Focus is via focus magnification which works well enough. I should have said that the lens is an early TTH and takes Waterhouse stops but I don't have any made up as yet. Performance is pretty good with just some chroma evident around oof edges but this cleans up ok in Photoshop.
