The biggest problem with film read mechanical cameras with some electronics is the problem of future services!
When I was still servicing watches and timing instruments,
average age of repairers was 65...like me.
Very shortly after my (65) b'day i had a heart excitement
and was effectively retired..
The situation with cameras and lenses is identical..
We all know all the service people left.
Here in Toronto, Gerry has now stopped working.
Using my Leica cameras means I must look at New Jersey or Wetzlar,
for official work.
States its Sherry, DAG or Youxin, who by reports do stunning work.
Nikon or Canon do not have any service people geared to mechanical..
Is the M6 built cheaper?
Erwin Puts and Erik say no..but the exp.counter
in my M6TTL is faulty due to usage of "plastic" spring.
Paint peeled off shutter dial..Flare the big surprise.
Faulty M new models not funny.
My M3 1155...'1967, one of last production arrived without some parts,
in rangefinder. 3 signatures in warrant and final test..
It happens in hand built items, as did a critical screw in a Rolex Chronometer, missing.
Came with so called observatory test..
It would have been damaged in 1st few minutes, never mind real test..
Buy used and hope for best.
If it ain't broken, don't fix.
