you are once again lying about what i said.

i said that people use the term long, long focus and telephoto lens
interchangeably, whether or not it's technically correct, the very
*opposite* of clinging to a rigid definition.

No, no one in the "real world" uses "long-focus lens" interchangeably
with "long lens". Just in your little world of "nope".

yes they definitely do. search for the term long lens and see what
comes up. you are once again, wrong.

When you search, using Google or some-such, you find articles written
about lenses.

what you're missing (intentionally, because it proves you wrong) is
that if one searches for 'long lens', the *first* hit is a wikipedia
page about long focus lenses.

in other words, google considers the terms equivalent, which is based
on real world usage. that's one of many reasons why google's search
results are better than others. it's designed to search on what they
mean, not exactly what they typed.

not only that, but the text on the wikipedia page uses the terms
interchangeably:
https://en.wikipedia.org/wiki/Long-focus_lens
Long-focus lenses are best known for making distant objects appear
magnified...Comparing magnification by using a long lens to
magnification by moving closer, however, the long-focus-lens shot
appears to compress the distance between objects due to the
perspective from the more distant location.

The "real world" is about what real people say when
they are in conversation. No one says "Bring your long-focus lens
today" or "I wish I had a long-focus lens".

eric did.

Real people in the real world use "long lens" and not "long-focus
lens". No one misunderstand that usage.

moving the goalposts again.

the issue are the definitions, not popularity of usage.

But, then, you are isolated from the real world and any interaction
with ordinary conversation. Real world people shun you.

more insults. that's all you do when you know you're wrong.

unlike you, i back up my claims rather than hurl insults.

in addition to the wikipedia link above (which is more than sufficient
to prove you wrong), there's quite a bit mo

the free dictionary page for telephoto lens is a redirect for long
lens, and it's description matches that of the wikipedia page for long
focus lens. in other words, they're all interchangeable.
https://www.thefreedictionary.com/Long+lens
(Photography) a compound camera lens in which the focal length is
greater than that of a simple lens of the same dimensions and thus
produces a magnified image of a distant object. See also zoom lens.

another reference combines all three in one paragraph (mostly one
sentence):
https://www.photographymad.com/pages/view/telephoto-lenses
A telephoto lens is a type of camera lens designed for taking
photographs of subjects at moderate to far distances. Also known
as a "tele lens" or "long lens", they are a type of long-focus lens
which use a special internal construction to give them a focal length
much longer than the length of the lens itself.

anyone who knows even a little bit about photography understands that
the terms are used interchangeably. *nobody* (other than you) would be
confused if someone said long-focus lens.

even the new york times used them interchangeably, in an article more
than 40 years ago. this is *not* anything new.

For most owners of 35mm cameras with interchangeable lens capability,
the most useful ³second² lens is a long focus lens‹that is, one with
a focal length that is longer than the ³normal² lens for a 35mm image
(the usual normal lens is 50mm).
....
All long lenses have the same problems in their use, and these
problems increase as their focal length increases
....
Another restriction of the long lens is its limited depth of field

as usual, you are once again wrong, you refuse to admit it, so you
resort to hurling insults. you are a sad joke.
