I still use a TOYO 45A using a roll film back (6X9) for 120 transparency and occasionally 4X5 B&W sheets for landscape work. My commercial/industrial work is all digital (Nikon D3 & D3x).
As far as "is it practical ?":
1- for clients: no they expect the immediate turn around that digital allows.
2- cost: not an issue. I scan my own film on an Epson V750. The delay in and expense of film processing is something that, each time, I question my sanity but I keep going back so......... If I had the need for a drum scan, I'd do it but it would have to be a very special image.
3- quality: reasonable depends on the print size and, to some extent, the subject matter.
4- file management: once scanned, it's another digital file to which I include references to the film original in the meta data.
5- practical: to each his/her own. I love working with the camera so for me it's a relaxing & refreashing outing.
All in all, I've spent more money on different things and didn't get as much out of it.
