Use the F50 for a while. And then...............While you're in Japan visit a couple of the BIG camera stores in Tokyo & try a couple
them on for comfort. There's no practical difference in results between 35mm cameras no matter what lies in peoples imaginations.
There is a difference in all the miscellaneous tests about different cameras but nothing you're going to see. I guess
that's good if you take pictures of the many test charts around us.

Especially for those who owned more than one camera, it was customary to forget about the pictures already taken and then get back from the lab prints of photographs completely forgotten! 
Shoot more with the F50 first of course...
