Canon cameras are all copies of a model the same quality

Yes
I am too young to remember but allegedly in the 70s some car companies suffered from variable quality.

Persumably with modern cameras this is not the case?
 
Eh, I think you are missing a few words, or a dozen.

Quality in what respect? Built quality? Image quality?

Both are you get what you paid for.

What I meant was and perhaps I wasn't clear.
If I buy a Canon R7 - and you buy one are they all the same?
I.e is there such a thing as Friday afternoon camera
Here is the definition of Friday afternoon car (I don't think it is true now)

Friday Afternoon Car - Meaning & Origin Of The Phrase

What's the meaning and origin of the phrase 'Friday afternoon car'?
www.phrases.org.uk www.phrases.org.uk
This is a British phrase and alludes to the belief that car workers lose interest toward the end of the week and make cars which are below standard. The first reference I can find to it is in the Usenet group ‘net.auto’, from August 18th 1983 ( at 5:54 pm if you want to be precise):


“Regarding the British car which leaked more oil … Some of my (British) friends would say you have a “Friday afternoon car” – one built on the last day when everyone’s in a hurry to go home.”

They are all the same.

Sure, one in like 100,000 might have a fault but so is like an iPhone.

The tolerances are really small.

I’ve not heard of Friday afternoon car, but have for Friday afternoon guitar.

Thank you for that.
 
I don't know whether *every* camera goes through a QC test, or a random selection, but there will always be one or two that falls through the process, but this is backed up by a warranty which is made easier when buying from a reputable outlet, who will put the problem right quickly.
 
Generally, I think Camera and lens manufacturers have very good Quality Control. A Club colleague mentioned that his Canon 24-105mm was not focussing precisely so we set up some tests and compared with mine which was spot on but confirmed the problem with his lens. His lens had been bought second hand and was now just over 3 years old. I suggested he contacted Canon anyway and they asked him to send the lens to them. They suggested that it had probably always been wrong and replaced it with a new lens.

I'll comment further. Since the Canon 350D in 2005/6 I've bought 10 Canon dSLR's. Some new. Some used. Two have had issues. Both happened to be new Hong Kong imports, although that has no bearing on the camera - they're all made in the same factories, (it had some bearing on the service received).

One had a screen which had a pronounced colour cast to it, and this was sent back. It was replaced and eventually I got a refund for the return postage - but it took several reminders.

The other had a very stiff shutter button which was replaced locally, but the HK seller wouldn't refund the cost as they didn't believe the hand written repair estimate was genuine or not - it was and some simple web searching would have confirmed it was a legitimate business, and one that I was more than happy to do the work.

Thank you so the quality is not the same always - thank you.

You're always going to find the odd one that has a fault but 99.9% will be the same.

Canon make 3 million cameras per year. I've had two with issues over a 20 year period.

I'm sure if you posted the question about Nikon, Sony or pretty much any other camera company you'll find someone saying they had one with little issues.

I agree but it is nice to know that they are not always the same.
 
I don't think you can base any conclusions on a thread with 15 responses.

Over the years I've had

Canon 600D
Canon 300D
Canon 20D
Canon 80D
Canon 5D (MKI)
Canon G5 X
Canon 5D (MKIII)
Canon R6ii

I've had no issues with any of them. But I did have an issue with a 50/1.8 lens going 'off'. When I first got it, if focused well, but after a couple of years everything was just slightly out of focus. Bought it new, never dropped it. Ended up with SH version when I bought the MKI 5D, so sold the dud one to MPB in a bundle of stuff.

As for Canon lenses, I've had.

18-135 EF-S
50/1.8 (x2) EF
50/1.8 STM EF
28/2.8 EF-S
24-70 LII EF
70-200 LII EF
100-400 LI EF
35-350 L EF
40/2.8 EF
17-40 L EF
85/1.8 EF
50/1.8 RF

I also have three Speedlites, a flash controller, flash cords, and some other stuff I've probably forgotten about and never had any other issues.

¯\_(ツ)_/¯​

 
In my opinion quality control has improved substantially however the quality of the components is designed to only last a defined amount of time before failure. Companies are always looking for cheaper ways to make products and not necessarily improving quality.

That’s a weird conclusion, if I may.
ALL mass produced goods are built to the exact same specifications. But with hundreds or thousands of parts, there will always be points of failure.

And whilst there’s a strong MTBF, you’re as likely to get a camera that lasts twice as long as you are one which lasts half as long.

oddly the best example of this consistency is when a genuinely faulty camera makes it to market. So an oily mirror isn’t a sign of a ‘bad camera’ but of a bad design.

Or simply put; completely robotic factories don’t suffer from ‘Friday’ products.

I can't comment on cameras - I've not had many different ones. What I can point out though is that the materials used in manufacture have tolerances. In Fundamentals of Lens Design (Kingslake and Johnson) there are interesting tables of the allowed variations in optical properties of what purports to be the same glass, specified according to the three different grades that you can buy. This implies that even if the lens maker has zero tolerances in manufacture, different batches of glass will throw things slightly off between lenses.
