The very first Obsession 617 took me 10 days to design and build.....it proved to be very successful, so I have now built more.
The body parts consist of 3mm aluminium, film advance and film spool spigots are machined from brass with the top and bottom plates fabricated from 6mm aluminium plate. This provides a very strong and
durable body shell. Lenses are sometimes difficult to find, however the 90mm f5.6 Super Angulon is a very suitable lens that has proven to be an excellent choice for the job. The first few Obsessions were
fixed focus having the lens set to its respective hyperfocal distance. This proved great for most subjects, especially landscapes, as at f22......... (the Linhof recommended aperture to obtain full coverage at the
corners on the 6x17 format), everything will be in focus from around six feet to infinity. I can hand build these cameras for around $900US, plus lens, (in case you'd like to supply one). I also include a
masked finder, double bubble level and cable release. Building these cameras MUST be an Obsession, otherwise I wouldn't keep doing it, would I?
