Default Does smartphone angle of view depend only on focal length?

What a lot of irrelevant blather!

nothing irrelevant about it.

digital is now the default. film requires a modifier.

'camera' or 'slr' is digital.


I suspect he means there's not much in your previous post (about 35mm
cameras etc) which addresses the points about focal length and field of
view.


it exactly addressed it.

tl;dr there are multiple sensor sizes, so a lens with a given focal
length can have different fields of view, even on the same camera.


Are you sure? I'm not, so I took another look at your post and can't find
a single relevant statement. Perhaps you can identify what you mean.
This is what I saw:

obsolete definition.


There are quite a lot of people who would disagree with your
characterization of "obsolete". A "35mm camera" is a camera that uses
35mm film- has been for many, many years, and will continue to be for
many, many years.


film is obsolete, as is your definition.


Irrelevant to focal length and field of view.

a '35mm camera', aka an slr, is now digital, and is compatible with
nearly all lenses and accessories in a given system (except for the
ones that started fresh, such as m43).


Irrelevant to focal length and field of view.

50 year old nikon lenses work on modern nikon slr bodies. the old
flashes also work, although only in manual or old school auto (no
ttl).


Irrelevant to focal length and field of view.

those old lenses also work on non-nikon bodies with a suitable
adapter, including canon, m43 and mirrorless.


Irrelevant to focal length and field of view.

winders and motor drives are obsolete, since there's nothing to wind
and digital can shoot faster anyway.


Irrelevant to focal length and field of view.

A digital camera that looks and feels like a 35mm camera, is a
"dSLR", or a "35mm form factor camera", or a "35mm-style digital
camera". A "35mm camera" is a film camera.


almost all cameras sold are digital, therefore the d is redundant.


Irrelevant to focal length and field of view.

i don't think the nikon f6 film slr (note the 'f') is even made
anymore (not that it sold very many when it was).


Irrelevant to focal length and field of view.

nikon's digital slrs begin with 'd'. guess what that's for.


Irrelevant to focal length and field of view.

in other words, digital is the *default* and film is the *exception*.


Irrelevant to focal length and field of view.
