The "50mm" might, maybe, be defensible as a sort of "35mm [full frame] equivalent image scale" because it's used that way so much in marketing of digital lenses. But even if so I can't imagine f/5.6 meaning anything other than it says, which is also pretty clearly just plain wrong.

Interestingly enough, you inserted the slash and used the lower case f in "f/5.6". Arguably, that is more accurate as a designation of the aperture than the "F5.6" on the front of the camera.

I was aware of the fact that a telephoto lens cannot be described in the simple way I described focal distance. I didn't see any point to compounding confusion. It's clearly a simple lens - so the simple explanation of focal length applies.

But what I was saying is that, even with the most straightforward exposition of an understanding of those numbers on the rim of the lens, it still will not be universally understood. Nothing is universally understood.

I beg to differ, the following are universally understood, +- =. In photography 1/60 or 1/500 is understood as the shutter speed. Likewise, the aperture on a lens is universally understood by the following f/2.8, f/4, f/5.6 etc. The correct designation is small f/2.8 and not F2.8

This would make a great title for an LP.
Very early on in my APUG experience, there was a thread that has stuck with me.
A new member who had some experience with 35mm film and cameras had purchased their first roll film (most likely 120 film) cameras.
They started a thread to post a question - "my camera only came with one empty spool - what can I do?!!!".
In addition to relatively easily quieting that members concerns by explaining how roll film works, it struck me how much experience and context many of us bring into these things - how much my 8 year old self with my birthday present Brownie Starmite learned and continued to both apply today, and how much we assume that others know as well.

Your qualification of "in photography" is really important here. These are well understood conventions, within the group of people who are "in photography". If the item in question was being considered by someone who never had a camera outside their phone, what would they understand?

Yeah, that's just the way I write it, because to me it IS more clear. But if it says "F5.6" that gets into the whole "well known in photography thing.

You must be kidding. Aside from "+" meaning either "add" or "positive", those symbols mean nothing to someone who has never encountered them - like a 2-year old.

In photography 1/60 or 1/500 is...

That qualifier alone means you assume no universal understanding.

Still waiting for it to become available so I can test it. And then send it back because it is not a 50mm f 5.6 lens.

Wow, Matt, I never knew that what I and a lot of others here regard as very clear to the "reasonable man on the Clapham omnibus" who is the often quoted person in U.K. law was so uncertain in, I presume, Canadian law and U.S. law Opportunities for legal argument seem unlimited

No wonder everyone wants to be a lawyer man in the U.S. Is it the same in Canada?

Good luck with the lawsuit. We know it can't be a 50mm "optic" because it's WAY too close to the film plane.

And anyone can sue anyone else, but that's no guarantee of victory. The first thing is proving damage, loss, harm, etc. I read in the New York Times today that a guy is suing a boneless chicken wing restaurant because the chicken wings are made from chicken breast meat -- NOT chicken wing meat. The menu clearly states that it is breast meat, but the guy is suing for emotional harm.

Perhaps you can use the same approach.

Yes I read that. His complaint is that he is being sold chicken nuggets pretending to be boneless wings.

I just feel bad for the chicken.

The "reasonable man on the Clapham omnibus" criteria is associated with civil actions, where individual people sue to be reimbursed. That involves a much less rigorous standard of proof - balance of probabilities - then an enforcement action commenced by a government agency, seeking to impose a penalty or other remedy.
There may be specific trade practice legislation that sets a lower standard of proof for particular marketplace concerns - but that would be exceptional.
