If there is no control, you can also get the worst piece.
Yes, that is where companies like Canon fall down. Their problem is a purely commercial one: do they spend the money on quality control or keep the price down and let the customer do the checking?
I suspect that you and I will agree that the manufacturer should do the testing.
In the 'fifties and 'sixties, British retailers like RG Lewis and the long gone Wallace Heaton made a major selling point out of their in-house testing facilities. Each camera, lens, etc., would be repacked with a certificate showing the results of their tests, before delivery to the customer.
Alas, such days are gone.
