Very nice little range finder that looks great and with a fast good lens.
It's easy to use with both auto or manual aperture.
Manual shutter speeds and manual focus which works great.

Image quality is nice and sharp, okay bokeh but quite ugly flare.

Camera do take a mercury battery but this is only for the light meter and the auto aperture mode.
Can still use in manual just as good without any battery.

One little odd thing is that the film advance lever don't have any stop after you advanced to the next frame.
Usually you need to take a picture before you can advance to the next frame.
This is not the case here and you can just go to the next frame without taking a picture.

This camera also have Canons QL system which stands for quick load.
Have hade some problems with this and film rolls that I have cut myself.
Did a own post about this which you can find here.

Thumbs up:
Sharp and good image quality
Fast lens
Auto parallax correction viewfinder
Auto aperture works great

Thumbs down:
Light meter don't give any reading in manual aperture.
Mercury battery
QL system can have some problems
