As for the f2.4 aperture with the 105mm lens on 4x5, aprox would be f4 to f5.6 would be close enough. There are many modern and vintage lenses that fit these numbers.
Possible to post a 6x7 image example made with the 105mm f2.4 Pentax 6x7 lens?
Medium wide on 6x7 would be about 60mm to 80mm focal lenght or 120mm to 135mm on 4x5.
If the camera involved is a Sinar (any Sinar) there is zero reason to exclude barrel lenses. Adding a Sinar shutter opens up the entire universe of barrel lenses that could be used to meet your image goals.
