charlesa you don't say what you want to do with these. If you are thinking of shooting film. Why? You have good digital equipment. If you are considering some fun or collecting, then I suggest you offer your friend what they are probably really worth. And I think you asked that to start with?
60 euro for putting on the shelf or admiring.
Take the best camera and the best lens if you buy them. Run a roll of film through it. Only buy one roll. Get the prints back, and I think you'll say, nothing but digital from now on.
There are some exceptions. If you want the softer film look for example. Low light, astronomy. I'm sure there are others. But I think you will see that digital has surpassed film by some far, that you won't want to spend the money on soft, pastel looking images.
