Great camera but it has had its day.
It uses regular 35mm, 135 format, film, developing is not difficult but can't be done through some machines, they don't understand the wider frame.
The trouble with them is to get any kind of quality from it you need to get good scans and again, most automatic machines can't handle the frame size, so it is speciaised and expensive. Or you do the scanning yourself which is time consuming and frustrating, well I found it was and gave up very quickly.
Though it takes a gorgeous picture, especially on slide film, in my opinion it isn't worth the trouble.
