The Flexaret VII is a good camera if the shutter is operating properly. The
shutter is one of the few that the shutter blades rotate 180 degrees, this
means that when you cock the shutter the blades reverse and go through an
open cycle. In order to prevent exposing the film, the diaphragm blades
close all of the way down and act as a blind. Then when you trip the
shutter, just prior to the blades starting to open the diaphragm opens up to
the set value, blades open and then close. This shutter is tricky to keep
in adjustment and most repair shops have never seen a shutter like it. The
Flexaret V and VI have a standard design shutter that is more reliable. Be
aware that the coatings on the lenses are very soft and typical lens
cleaning fluid has been known to remove the coatings.
The Autocords are excellent cameras with only one common problem. The focus
helix grease is known to harden up. If someone forces the focus lever when
the grease has hardened, the lever breaks. So, if you get an Autocord make
sure that the focus helix has been relubed. The Autocord came with 2
different shutters, Citizen (Optiper) and Seikosha. Many prefer the Citizen
shutter, but I personally don't see much difference in them. I have had no
problems repairing either one. If you do find a camera that has had the
focus helix relubed, make sure that the camera has been recollimated. About
half of the Autocords that I service are out of focus due to being serviced
without the proper autocollimator test equipment. Most of the Autocords
appear to have a lens that should easily give 80 line per millimeter (much
sharper than the Yashica or even Rolleiflexes). One of the more dependable
cameras around (my preference for buying and repairing).
Ricoh 66 is an anomaly camera better left to a collector. The Ricohmatic
225 is very similar in design to the Autocord (same film path for maximum
film flatness, same excellent lens, similar focus helix but rarely does the
grease dry out, better baffling than the Autocord). One of the things that
I have noticed on the Ricoh camera is the ground glass appears to only show
about 92% of what will show up on film, whereas the Autocord is closer to
95%. The Ricoh Diacord is an equally good camera as the Ricohmatic 225 but
it does not have a crank film transport or auto cocking of the shutter. The
main thing to watch out for on a Diacord is the knob wind should only go in
one direction (about 2/3 of the Diacords/Dias that I repair have a broken
film wind knob). The Ricohmatic 225 is an excellent and durable camera with
the bonus of 35mm film capability, this is a very dependable camera. The
Ricoh/Ricohflex Diacord/Dia cameras are simpler quite dependable (manual
film cocking, knob wind).
The Yashica with a Yashinon lens typically is quite good. I have found
several examples where the focus moves as you adjust the diaphragm (this is
due to the diaphragm not being at the lens nodal point). The Yashicamat
124G last model is mostly plastic (front lens board cover is plastic) and
the wind mechanism is very cheap (sounds like a coffee grinder when you wind
it). The earlier Yashicamats (including the 12, 24 and 124) are well made.
My preference is to not work on a Yashica because of the frailness in the
whole camera design.
