Yes, these are great lenses, as are the Leitz Photars, and fine Olympus and Canon FD macrophoto lenses that will cover medium and large format at high magnifications. These are all of similar design and purpose.

Here's a picture with the FD 35mm/f:2.8 Macrophoto on Kodachrome 25:



I've adapted the lens so that I can use it on my Bronica, and it wouldn't be difficult to use on 4x5" either, but haven't found an interesting subject for it yet in medium or large format.
