Here is what I want: A small, quiet, and preferably mechanical compact 120 rangefinder/folder and I do not need a meter. Fuji GS645s I'm attracted to this camera because it seems to have everything I need and not much more. 1. Do you guys feel comfortable switching from landscape to portrait orientation? I know that the native format is portrait but is it comfortable to switch into landscape? 2. I know there are bellow problems but is it easy to service your own? 3. Do you find this camera durable? I do not intend on babying this camera. I plan on putting it in a sleeve/case and tossing it in my bag or slinging it around my neck. 4. Anything else I should worry about?
