Typically,  yes.

However,  the Baby Graflex is a
LF camera for 2 1/4" x 3 3/4"
(approx. 57mm x 76mm),  which
is most certainly in MF territory.

LF cameras are probably better
characterized as using sheet film
or film plates rather than roll
film.

But then again,  rollfilm adapters
are available for Graflex backs ...

I haven't used my LF gear in years.
(I know I still have it,  as I just
moved it from a closet to under the
desk so that I can get to the attic
access.)

LF seems like nostalia now.  If I
want something wide,  I just stitch
some 10D exposures together into a
panorama,  and I'm making money
with the 10D  not the Toyo 45 ...
