    4x5 meniscus lens camera

    Here is a large format camera 9 built with some simple pieces of wood and one meniscus lens



    A classic 4x5 chassis and two bent wood pieces (for shelf)



    the bellows is made from a black cardboard sheet, and joins the front plate and the chassis. the front plate can slide regarding the bottom plate with a piece of metal for focusing.



    the lens is a meniscus with 120mm focal length, it is closed with a 4mm diaphragm sor the fstop is 30.



    and the result on a fomapan 100 4x5 film exposed 1s (contact print)

    A beautiful camera, simple, clean design, very well done. Excellent idea to use these bent wood pieces. Do you insert a ground glass for focussing or do you the focussing with some distance marks only? The first results of the camera are very good, excellent portraits of a nice young lady.

    Cool design. Shows what a simple approach can produce.

    Thanks all of you !!

    renon> Indeed I used a ground glass for focusing, it is however just a piece of unpolished glass that I positioned at the place of the 4x5 chassis, I plan to build an insert with a glass that has the exact placement of the film sheet. So this first test has been approximately focused..... well I also have a mark for infinity focus
