The X-370 is a pleasant camera to use and has a nice bright finder. When I had one I found the older MC Rokkor lenses with the depth of field preview tab. The capacitor replacement is an easy repair. I eventually traded my X-370 for an X-700 so I could change the focusing screen but bot are good. All of the 50/1.4 Minolta manual focus lenses are good.
Yes it is, remove the bottom cover and there it is ready to swap. But, if you have to order and pay shipping on one single replacement 3v 100mfd (IIRC) miniature capacitor, it becomes not worth bothering with.
