I have a 120 film back for my 4x5 but rarely use it because it is so much easier to use my 6x7cm camera.

Another roll film adaptor which slides under the ground glass just like a double-sided film holder is the Calumet C2, available used on the 'net: http://www.southbristolviews.com/pic...df/ins_c2n.pdf.

Huge experience. In some ways it parallels the
questions about using full frame lenses on crop
sensor cameras. A rollfilm back is a reduction
in format, but the lens and "lens carriage" still
remain optimized for the original, unreduced
4x5 format.

"Lens Carriage" refers to not just the lensboard
and not just the lensboard-plus-front-standard.
The bellows and camera bed [or monorail] are
equal to the lens barrel and focusing helix of a
35mm or rollfilm camera. So, everything on a
4x5 camera, except the rear standard, is built
to be large format, not medium format. [The
rear standard obviously CAN become medium
format, or we wouldn't have this discussion].

Just as when a crop sensor camera is using FF
lenses, there's a 1.5X factor [approximately],
and as with crop-vs-FF, the problem is really
with wide angles. But, it's even worse with a
view camera. Not only is there the narrowed
FoV, but there's also the movements. The size
of the standards is too large, and the bellows
too long. Some designs are worse than others.
A field camera works better than a monorail
view camera which, given your intentions, is
good news .... or reduced bad news. Depends
on whether you're the glass-half-full type, or
the other type.

In my own experience, rollfilm adapters for 4x5
cameras is a very handy option, so that I always
preferred rollfilm friendly 4x5s, when I was still
using film. But these cameras were always 4x5
primarily, and rather compromised as rollfilm
cameras.

There is one more problem. And it departs from
the FF-lens-on-crop-sensor-camera analogy in a
quite unfortunate way. There's plenty of lenses
dedicated to the crop sensor format. No crop
sensor user should feel forced to use FF lenses.
There's plenty of lenses for 4x5 view cameras
but almost none for mini view cameras. This is
prolly cuz there's almost no mini view cameras
ever built. Their typical lenses were the 47 and
65mm Super Angulons, and the 100mm Symmar.
Go to ebay and compare availability of that trio
to 75 and 90mm Super Angulons and Symmars of
135, 150, and 180mm [primary choices for 4x5].

So even if someone acquires a mini view camera,
finding lenses for it can verrrrry discouraging. If
you find a complete mini outfit with a normal, a
wide angle, and 2 or 3 film holders, snag it
