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:

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film is obsolete, as is your definition.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.

previous posts directly addressed the field of view issue.

someone wanted to argue about modern digital cameras (the topic under
discussion) and obsolete film cameras, so i responded to that.

that means that 'film' should be a prefix when referring to an old
school camera and its absence means digital.

Deal with it.

that goes for you.

nothing irrelevant about it.

digital is now the default. film requires a modifier.

'camera' or 'slr' is digital.


But Sam Brown's original post referred to a "35mm camera". No matter
how much you continue to argue, the description '35mm camera' refers
to the film size used by the camera. Such cameras cannot be digital.

of course they can

one example:

The K-1 combines the performance of a full frame 35mm digital
camera with the unique PENTAX original features you love - all in a

Hmm "403: Access Forbidden - Your location (NZ) has been blacklisted."

I wonder what lies behind that?

In any case, an advertising blurb does not enable a digital camera to
use 35mm film. The K-1 is not a film camera.

that's funny.

apparently enough new zealanders are up to no good that the entire
country has been blacklisted.

perhaps it's time to move to a more civilized country.

short of that, try nz.ricoh-imaging.com or start from their main page
and find it, use a search engine or use a proxy from a non-blacklisted
country.

what i quoted lies behind that (and more).

it doesn't say it uses film or is a film camera.

it says it's a 35mm digital camera.

Gotta agree. It was not that long ago when i could have purchased a
digital back for my F3, from Kodak. IIRC it was only about $10,000.

If you read the article you cite, it clearly states on the first page:
"Take greatness to the next level with the first compact, full frame
DSLR engineered by PENTAX for outstanding performance, operability and
affordability."

And further down it also states: "Designed to move in ways never before
imagined is the new Flexible Tilt-Type LCD Monitor - a first for any
DSLR camera.."

If what you say is true, I wonder why it is called a "DSLR." My guess is
that the copywriter did not consult you.

as opposed to being engineered for mediocre performance, inoperability
and unaffordable.

And further down it also states: "Designed to move in ways never before

what if someone actually did imagine them?

obviously someone had to, else it could not be designed that way.

your guess is correct. i was not consulted.

'dslr' is still used, however, the d is redundant.
