I had two 4x5" enlargers but gave both away when we moved. I have two 4x5" cameras still. A studio rail type Omega View, very similar to a Toyo. My other is an old Gunlach wooden field camera. The "leica" of view cameras are the Sinar and Linhof. With view cameras the brand mean little as the camera is just a means of holding the lens and shutter, and to hold the film in place. The main issue is the view camera needs to be steady yet have smooth and precise movements. Not all that hard to achieve. Other used view cameras like Calumet, Burke & James, B&J, and Kodak are fine to use. Wista, other kits can be good but not all models and new wooden cameras are expensive. Look for used in general. What is most important is good glass, same as always. For large format lenses like Schneider and Nikon. There are also Rodenstock, Calumet, and Kodak (old). I prefer Copal shutters, but I also have Compur. These days when I shoot 4x5 I scan the film and then work digitally.

If you wanna use my extended 35mm 3-frame carrier you’ll hafta get an Onega or I could ship you mine, just pay for crating and freight !

In the early days of digital conversion from film I actually hoped there would be a digitizing easel for existing enlargers ... some kinda scanneresque thing but without it’s own light source. I have no doubt that it could work. But obviously the market went elsewhere.

Not only do I know it would work, but I had already used its precursor. I made 35mm B&W positives and internegs by substituting a Nikon body without its prism in place of the enlarging easel. Just takes a whole lotta lens extension to get rollfilm reduced to 35mm format !!! Like a duping rig built upside down. IIRC I swapped the 80 or the 50 onto the cone from the 150.
