(20.5in), and No5a= 60cm (24in.) These are symmetrical anastigmats, 3+3 type and possibly Dagor or Collinear types This is Hermagis Trousse Aplanastigmatique n.5 and it consist of: 2 cells n. French designers always made some littlle or huge change in exixting optic configuration. Not an Aplanat or rectilinear but an anastigmat with a French design of lenses, that means somenthing particular. Here another example of casket set with special qualities. I will post some 4x5 photos as soon as I print them, for 8x10 you have to wait until Christmas.Ī little bit too optimistic about casket set performances I put it in front of a Copal 3 with adapter ring in a 8x10 camera and it is weird! Single lenses are usable but with more or less the same results of the combinations. With small apertures the focus increase until 55-60% and with long combinations it cover barely. This for 4x5 format and medium combinations of lenses. Results wide open, with a combination, are very similar to an Holga lens, very small focus in the centre of the image and a complete out of focus for the rest 35% focus and a big amount of blur. There are waterhouse stops as follows: f25 f20 f15 f10 f5 f2 and the place for the waterhouse is very near to the front lens. They get in position on the barrell with two very large washer stops. The focal length is roughly script on the edge of the lens. It is composed of the following sigle lenses: 60, 48, 40, 30, 25, 20 centimeters. No name or indications, it seems a French manufacturer but it is only an assumption. That's right Brian here I'm and to improve the dependence I introduce you the most simple casket set I saw and used. Images on the ground glass wide open are very portraitist-style, plastic and soft in the same time, close down it became more sharp. It is an Aplanat or rectilinear with a medium/small coverage around 60 degrees and it was used mainly for portraits and groups as catalogue said. The cells are six, two for every focal length:Ĭombined cells with coverage in centimeters It is composed of barrell with one washer stop, I had have made the others to test the casket set. For this purpose I have consulted an old Meyer catalogue.
I determinated the origin by measuring the aperture wide open and it is f 5,5 and the design of the lenses, symmetrical aplanatic construction, is the same of Aristsoskop. Manufacturer is Hugo Meyer & Co - Gorlitz no number, neither incription on the barrell. I will try to do my best for the next Meyer You are right Ole since my knowledge of German language is very close to zero and your consideration makes more sense then mine since I bought this one in Germany.
