Originally posted by cheekygeek I really don't get the point of using 120 film in a 4x5 view camera, but maybe I'm missing something.
The advantage is being able to use roll film at what is still a fairly large format (120 roll film holders go as large as 6x12cm) and still have use of all the camera's movements. My roll film holders (I have three) are all 6x7 and they work great for many types of shooting.
Plus side relative to 4x5 sheets:- Much lower cost per frame for color work
- Less bulk per frame
- Easier home processing
- More reach with less bellows extension for close-up/macro and portraits
- Ability to use lenses with a somewhat smaller image circle. In many cases this will result in lower cost and/or bulk.
- Where a 6x7 (my holders) view camera simply makes sense
Minus side relative to 4x5 sheets:- Wide angle on the smaller format is a pain with most view cameras. This is less the case with 6x9 and 6x12 where a 90mm will often suffice. For 6x7, a 45mm or 60mm would be more useful, but less practical for several reasons.*
- When you need the larger 4x5 negative in order to minimize the grain of faster emulsions
- When you need the larger negative in order to maximize the captured detail
- Where a 4x5 view camera simply makes sense
If the above two lists look a lot like the APS-C vs FF debates, that is because the two are somewhat similar. What's more there are those who would suggest that 5x7" or 8x10" are more appropriate than 4x5".
In regards to wide angles, 6x7 tends to "shoot wide" relative to 3:2 formats. An example would be the waterfall in the photo below:
Shot with a 90mm lens, the waterfall is about 75 feet high and the base is about 50-60 feet away from the tripod position. The camera movements help some too. I believe that front rise and both front and rear tilt were used for this shot with the camera bed being inclined upward a little toward the falls.
The same falls taken a few years earlier with the K10D at 18mm and about 10 feet closer to the falls. The same small boulder is visible at the lower end of both frames.

* For those not in the know, view camera lenses are usually of symmetrical design such that the lens board position is at the focal length for the lens. Many camera bodies are not able to accommodate 60mm and shorter lenses with full movements and many not at all even when using recessed lens boards.
