Yeah, medium format rollfilm and 4x5 sheet film cameras are not terribly complex machines. But film is a technology and a methodology firmly rooted in the past. For the beginning shooter, modern digital offers a fairly easy way to l shoot lots of shots in a day or week,at very little cost. And with instant or nearly so feedback not shoot wait to finish the film, then develop to see the results. Speaking of seeing the results, digital images are instantly ready for viewing on the computer monitor, with no need for printing out or projecting.
Years ago I had a Fuji S2Pro, and a long time ago (in 2005 or 2006 I expect it was),I calculated that for its $2,400 price tag I was able to shoot the equivalent of $69,000 worth of Ektachrome 100 to 400, in about two years' time. I shot a lot of photos with that Fuji, like I said, at $6.99 per roll for film and $4.99 for a 36 shot roll of slide film development. Compared with shooting film, my costs were vastly lower per image with the Fuji. If I took a bad shot with digital I was able to spot it right away, and to reshoot.
I came to digital with over 20 years of film experience. I knew a lot about photography, and about lighting, and about lens work. While I understand film completely, and can operate 35mm single lens reflex and rangefinder cameras, and medium format single lens and twin-lens reflex cameras, as well as 4 x 5" monorail and press cameras, and I have owned all of those types of cameras, I personally do not think that there is a better camera than a modern digital SLR, in term of speed and ease of operation, and for ease of "getting the shot".
Film had a good 100 year run, before it was largely supplanted by digital imaging. The wired telephone had a similar run of success, but it has largely been supplanted by the cellular/mobile phone. There's nothing "wrong" with older technology , but newer technology does bring with it some benefits that are lacking in the older technology. While I used to have a typewriter, I sure do not miss ribbons and white out, and the need to do every single thing with extreme care. I really prefer modern word processing software, a computer, and inkjet printing. But, I speak from experience of a person who learned on one technology, and who then transferred to a newer technology, in a lot of areas
