  1. We have them in the UK too, delightfully lampooned in this book. Alan
  2. I thought I would add these photos here, rather than start a new thread about this odd accessory with a Leitz family connection. I’ve just acquired this Kühn Flexameter and here it is atop a contemporary Leica IIIb. In use, the image in the Flexameter is focused on a rather dark ground glass screen – the view is actually clearer through the camera’s own viewfinder, and focusing is easier with the camera’s own rangefinder. Maybe mine needs some cleaning, but I can’t find a way to remove the glass screen to get to the innards. I suspect that Flexameters were of more use on the I series of Leicas (rather than the II or III series), except that they don’t fit – the I series shutter speed dial and viewfinder would make mounting a Flexameter impossible without adding some height to the accessory shoe first.

  3. I see that Light Lens Lab are also making a copy of the old 35mm viewfinder (SBLOO/12010) in black - see here https://www.ebay.co.uk/itm/New-Light-Lens-Lab-35mm-f-2-Viewfinder-Black-Box-/165103591364. Alan
  4. That seems the most logical reason, I think. I see that from 1935 to 1939 the prices did not increase, in fact one conversion - from a Model I with interchangeable mount to a Model III - got cheaper by 6d. Alan
  5. I came across this interesting Wallace Heaton advertisement recently. It appeared in the May 1939 issue of The Miniature Camera Magazine and shows the various upgrade options available for different Leica models; it also gives prices for converting non-coupled lenses into rangefinder-coupled lenses. I see from the advert that most pre-Leica III models could be converted into a Leica III and also a IIIa, but a Leica III could not be converted into a IIIa. Can someone explain why a Leica III could not be converted into a IIIa? The earlier models and the Leica III all have a top speed of 1/500 second, so all would need 1/1000 added to turn them into a IIIa (plus slow speeds – they already exist on the III). Why could 1/1000 second shutter speed be added to pre-Leica III models, but not to the Leica III itself? Alan
  6. My small collection includes a similar 1931-vintage 50mm f/3.5 Elmar lens, marked in feet, with a standardised '0', and also with a '5' behind its 'bell-push' lever (#122672). Alan
  7. I have successfully removed old screen protectors with the use of a length of dental floss carefully looped under a corner of the protector and gently pulled from side to side under the protector. Some glue residue usually remains, but that can then be cleaned off afterwards. Alan
  8. I had my 1954 Summaron 3.5cm f/3.5 cleaned and serviced by Cameraworks here in the UK earlier this year. I consider it money well spent and it's now one of my favourite lenses. Alan
  9. Many years ago - in the early 2000s, I think - on another Leica forum, a member there was converting an LTM camera into a digital camera. He made good progress, but then the M8 came out and I think his work came to an end. Alan
  10. I've found another mention of a possible Ogilvy connection in Filippo Giunta's 'Systematic Approach' book. On page 64 he says: "The close focus Leica I had a near focus distance at1,5 feet and was produced mainly for export (Ogilvy & Co. UK)". He illustrates the close focus version with No 27056. Alan
  11. As the original enquirer, I'm most grateful for all of your thoughts and comments. I seem to have set quite a hare running ... Alan
  12. I have an old copy of Neill Wright and Colin Glanfield's book 'The Collector's Checklist of Leica Cameras, Lenses and Accessories'. In there the authors note three different focus-scale versions of 50mm Elmar lenses on Leica I (Model A) cameras. They state: "(a) normally infinity to 1m (b) infinity to 3 ft (uncommon version) (c) infinity to 1.5 ft. This version was apparently only made in feet, about 1927-1930, and may represent a special large order from the importers, Ogilvy & Co, for sale on the UK market." I have no idea whether the authors' suggestion re Ogilvy & Co is correct, but it sounds like an interesting possibiltiy. Alan
  13. With a bit of Googling, I've found a website at https://www.aleica.nl/en/leica-fact-17-leica-1a-variants-elmar-lens. This states: "Apart from the cameras with the lenses in meter, also lenses in feet have been delivered. Until approx., serial number 2400 the “feet” ELMARS the shortest focus distance was 3,5 feet. Between number 2400 and 46000 the shortest focus distance was 1,5 feet (Close focus Leica). After 46000 3,5 feet was the standard again". If the website is correct, it would seem that the earliest and latest I(A) cameras has non-close focus 50mm Elmar lenses. Alan
  14. I recently acquired a ‘close focus’ version of the Leica I (Model A), s/n 43675, which set me wondering about this model and the following questions in particular. · Of the 56,000-odd I(A)s fitted with a 50mm f/3.5 Elmar lens, how many had their distance scales in metres and how many in feet? · Of those marked in feet, how many were of the ‘close focus’ variety, focussing down to 1.5 feet (18 inches)? · If you wanted to buy a I(A) marked in feet in the 1920s/1930s, was the close focus version the ‘normal’ model, or was it outnumbered by the non-close focus version? Were both versions available at the same time? · Was there a close focus version with a lens marked in metres (approx 50cm)? If not, why not? · What was the purpose of being able to focus to 18 inches? At that distance there would be considerable parallax error in the viewfinder, and film plane to subject distance would need to be measured precisely by hand – the Leitz accessory rangefinders did not focus that close. Any thoughts on the above – or answers – would be much appreciated. Alan
  15. I've found that 'Brasso' (impregnated wadding for polishing metal) also removes sticky label glue - even if the residue is decades old. Alan
