    Howard Grubb Aplanatic lens for 12x10 plates made in Dublin c mid to late 1890s. The lens is made from aluminium, which was a relatively new material at the time, and it is considerably lighter than the 7 earlier Grubb lenses in my collection, which are all made from brass.

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! My earlier Grubb lenses, dating from the 1850s to the 1880s,  either have washer or Waterhouse stops. This one has a diaphragm, shown here at f22.

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! The aperture range goes f 11.3, f16, f22, f32, f45, f64. The Royal Photographic Society aperture scale, introduced between 1895 and 1902, included an 11.3 setting. I feel that the lens was probably before 1900 and, so, I am saying mid to late 1890s.

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! The lens itself is orange tinted. This is not a balsam issue, which some of my earlier lenses have, albeit with no optical problems arising. This is quite different. I suspect that the lens was used for a specialised application requiring high contrast. Possibilities are astronomy, science, industrial or military. By this time, Grubbs had started making items for the military such as rifle scopes and, later, periscopes.

    Pyrogallol reacted to hiphopopotamus in Is shooting film still worth it in 2022 ?   
    Interesting thread. I'm coming from a position where I'm now debating only shooting film from this point forward.
    I came to Leica from Canon (5DSR) and Sony (A7, various) a few years ago - ultimately I was looking for simplification of my photographic process, and a camera that would feel like an extension of me, rather than me being an extension of the camera. I originally went for an M8 and loved it, but felt a little constrained/disrupted by the crop factor. So moved to the M240 - didn't like it at all - it was far too much like the overly digital world I was trying to get away from. Settled on an M9 Monochrom and loved it again. I still have the M9M - for now...
    But in the past year or so I have also picked up a Mamiya RZ67 and a Voigtlander Bessa T 101. My first instinct now, whenever I go to shoot seriously anywhere, is grab the Bessa T. It's beautiful, light, and the 101st anniversary I have is built like a brick (in the good sense). Further, if I know I will have time and space to think about my shooting, and also not have much distance to physically carry the thing, I pick up the RZ67. It is interesting because, while I have shot film with Barnack Leicas and Contax RTS cameras in the past, I wasn't attached to them like I am my Bessa and RZ.
    I haven't picked up the M9M in months now. As a result, I decided to purchase an M3 recently, which is currently off getting CLA'd and reskinned. The idea being that my Bessa T (without in-built viewfinder) would serve as my wide-angle/specialist lens camera, and the M3 my 50/90 "people-lens" camera. But this decision has left me with a dilemma. I'm now think it's exceedingly rare that I'm ever going to reach for my M9M again in serious situations (I don't do photography professionally, for the most part, so have few of those pressures). And having that store of money there that could go toward another beautiful lens, or even another film M, is making me re-think its presence in my bag.
    So I recently picked up a cheap Olympus OM-D for the moments that I absolutely need good digital output. I'll use it with my Leica lenses via an adapter. And in most situations, modern phones do a decent enough job of digital output for me anyway - I'll never be looking to print from digital any more, and I'm not an instagrammer/online photo sharing platform user (outside of the odd picture here).
    Which leads to the logical conclusion - I think I'll let go of the M9M.
    Never thought I'd find myself doing this so soon after falling hard for the M9M, but the reality for me is that - as with many here - having found the right type(s) of film camera for me, I love the process associated with film much more than digital. And having recently done hand printing workshops, I now look forward to the whole image-making process from start to finish. I don't think digital will ever give me that type of pleasure...
    So I'm happy to eat the cost of film. It's an entirely different type of joy.
    ...
    ......
    but ask me again in 3 months when I'll no doubt have convinced myself to buy an M11.

    I have long been attracted to the Minox subminiature camera. Like the Leica with Barnack as the driving force, Minox had Walter Zapp in Latvia with true entrepreneurship. Surviving the war, and Soviet control of production,  and relocating to Wetzlar, and subsequently to Heuchelheim and Giessen.  There are several books on the development history.  Compact precision to produce big photos from small negatives. A slogan Leitz used for years.
    My Minox collection appears here, looking somewhat in disarray. But represented with 160 examples of this 8 x 11 camera, including 17 made in Riga, and 30 of the low production model II of 1948/49, and 24 of the relatively uncommon BL version. Along with all the accessories, enlargers, projectors and literature, it has been an enjoyable exercise. Of course one never gives up looking for the hard to find examples. How many other Leica collectors have been drawn to the Minox?

    Leica I Model A converted to a Standard and fitted with a Dallmeyer Popular 3 inch f4 telephotos lens. The camera has a 0 on the mount and it has an additional screw-in mount which converts from LTM to cine C mount. The camera is from 1930 with a serial number of 33875 , although from some angles the '8' looks like a '6'. Note the flash sync which seems to have been added later. The item on the left is a lens hood for the Dallmeyer lens.

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! This camera was obviously converted in 1933 or later. Earlier, Dallmeyer had offered the fitting of the 4 inch f5.6 Dallon Tele-Anastigmat to the I Model A as this advertisement by Sinclair from around 1930 shows. Note that the lens goes into the actual Leica mount and is obviously matched, thus giving a very early interchangeable lens Leica as the Standard Elmar 50mm lens could also be used.

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! Here is I Model A SN 33620 ( not far from mine) fitted with the Dallmeyer lens

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! The Dallmeyer lens would have been engraved with the SN of the Leica to show the matching. Alignment marks were added to the Dallmeyer and the Elmar to ensure proper registration when the lenses were screwed on.

    Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! Note the swing mask for the viewfinder for use with the 4 inch lens. I don't have the swing mask, but I can use any of my finders for the 7.3 cm Hektor which is close in focal length to the 3 inch lens, although coverage should be different with a  C mount lens. I'll experiment with a roll of film. My camera, being standardised can, of course, be used with any standardised Leica lens, including the 50mm Elmar, 7.3 cm Hektor and the 9cm Elmar and with a VIDOM or VIOOH or a one lens viewfinder. 
    Another interesting fact is that interchangeable mount Leicas were being produced in England even before the I Model C, as early as 1928 in some cases. Some of the lenses used were British eg Ross and Dallmeyer , but some were also converted to take the Meyer Kino Plasmat f1.5 1 and 5/8th inch lens, which was a very fast lens for its day.
    My item is perhaps the tail end of that story. I could have put this in a 'Leica thread', but the story more properly relates to what happened to the cameras later in Britain

    Pyrogallol reacted to George Furst in working Ur-Leica?   
    The greatest challenge facing you is the diameter of the shutter curtain rollers. If their diameter is too large, you cannot collapse the lens in between the rollers. If you make the rollers diameter too small, the shutter does not function very well as the radius of the shutter does not have enough torque to function well when you release the shutter curtain. Also if the shutter barrel is too small in diameter, the spiral spring will not fit inside the shutter barrel or it will bind inside the shutter barrel! 
    The critical dimension is not only the diameter of the shutter barrels but their diameter when the shutter curtain is rolled on one shutter barrel when the film is wound in preparation to take a picture, an the diameter of the other receiving barrel when the curtain is wound on it when the picture is taken. Related to this the receiving barrel has inside a spiral spring that is connected to the adjustment knob on the top that changes the shutter speed. In one of the above discussions it is said that the original UR had only one shutter speed. This is not correct. There are multiple speeds of the shutter curtain and they are controlled by the knob on the top of the camera that is connected by a gear to the spiral spring inside the shutter barrel. The highest shutter speed is obtained by moving the topside knob in the direction of the arrow under the shutter release button that is chrome. As you rotate this knob, you loosen the spring internal to the shutter drum and thereby change the speed at which the 8 mm shutter moves across in front of the film. I have estimated my original UR Replica, the first one made using dummy No. 38, as changing from 100th/second to 300th/second. This was estimated by taking picture of water drops falling from a fountain at my university and comparing the blur using a film camera with a shutter that I know the shutter speeds and can change them between 60th and 1000th/second. I know that the speeds are an estimation but it is the best I can do. I know the shutter speeds vary quite allot just by the sound of the moving of the shutter between slow speed and the fastest shutter speed. 
     
    in the later iterations of this camera,Barnack changed the shutter speeds in a more elegant way by having two shutter curtains here one can change the width of the shutter curtain window. This is definitely more elegant but at the same time this leads to the failure of the curtains because one of the ribbons fail. Also it means that you need two shutter rollers holding the curtains that each have springs inside. This has been one of the major failure areas of the Barnack screw mount cameras. The single shutter curtain in the UR is not elegant but the part of the curtain glued to the shutter rollers is a much larger surface and thereby not as vulnerable to curtain failure. Those ribbons on the later screw mount Leitz shutters are very small and thereby the UR is less prone to failures of the shutter curtain. Also the shutter curtain with the 8mm window is very robust and not prone to failure. I have been using my UR Replica for Five years not and never had problems with the shutter curtain.
    I wish to again say the Mr Kim should receive recognition for what he has done. And what is amazing to me is it only took him 6 months to make the first replica from the dummy. He is a legend here in Korea and has a devoted following and even a movie made about his many accomplishments. It is critical the watch making was his first profession. And no fear of trying a challenging project. Certainly making the UR into a working camera is very challenging. The small size of the camera external and internal space makes it an almost impossible task!
