"35mm cameras" are not digital.

they are now.

The "35mm" part refers to a film size.

originally, it did, but now that film is dead, it refers to the camera.

There are digital cameras that are "35mm form factor", "35mm style(d)",
"dSLR", and many other similar terms. But a (common) digital camera does
not use 35mm film, therefore, it is not a "35mm camera". A "35mm camera"
is a camera that uses 35mm film.

it obviously refers to the form factor, not the non-existent and no
longer relevant film size.


Even that is bull**** (on several levels).


not at all.

DSLRs of today are heavier
and more bulky than their eqivalents of the past.


nonsense. they're comparable in size & weight, with digital slrs often
smaller and lighter in weight than film slrs.


Not with a sensor of the same size as the image frame in a 35mm film
camera.

you're also ignoring the bulk of all the film one needs to carry (and
keeping it cool if necessary), versus a memory card, or more recently,
sync to the cloud and no memory card (i.e., unlimited photos, something
not possible with film).

They in no way share
the same form factor.


they most certainly do.


I have owned a few of each and I know you are wrong.

film nikon n90:

digital nikon d40:

not only do they look nearly identical, but they accept the same
lenses. in fact, the nikon d40 will accept the old nikon non-ai lenses
without issue, which the n90 cannot. in other words, *more* lenses.

and for an even closer match, there is the nikon df:

And I can buy several makes of 35mm film from a
number of outlets within a few miles from me. It is not
"non-existent".


compared to digital, it very definitely is:

be sure to zoom in, or just look at the relevant portion:

as i said before, calling it a round-off error would make film seem
bigger than it actually is.

put another way, in the time it takes you to go to a store, buy a roll
of film, shoot some photos and then go back to that store and have it
processed, roughly a billion digital photos will have been taken.
