9... the Dynax / Maxxum 7 is a great camera, at least if you are not afraid of buttons! I love the unique abilities of storing exposure data, the huge well illuminated status display on the back, great for night photography with long exposures. I also regularly swap out film (change B&W for color or change speed) using the film reload capabilities. Works very well, just make sure you write down the last frame number on the film roll to avoid double exposures. Also note that reloading film requires you to set the "leader left-out" option in the custom menu. In addition, if you would like to keep track of the stored exposure data, also write down the unique ID that the camera assigns to each roll when unloading a roll that needs to be reloaded. The camera will assign a new unique ID once you reload, storing the exposure data under that number, so you need to combine the data from different "virtual" rolls if/when reloading film. Can be messy at times to reconstruct if you forgot to write down the ID's on the film roll.
I do it this way:
"Last exposure number - roll ID"
e.g. a film roll may have this written on it:
12 - 0139
21 - 0142
34 - 0148
Autofocus speed may not be on par with the most modern digital bodies, but I must admit I don't own one of these modern SSM lenses. Would love to try one out once on this body for shooting action / sport photography.
