I recently got my Retina IIc serviced. Slow speeds were toast, and the rangefinder spot was invisible.
It's now home again and seems to be working great. The rangefinder spot is still not awesome, but it is usable, and the speeds all seem to be right on.
I threw in my last roll of Ektar 100, since that seemed appropriate, and gave it a go. It did really well.
It's an easy camera to carry for a walkabout, and the lens is sharp, with good color (when you aren't taking pictures of mud).
Really great for travel apart from the kluge that is the wide and telephoto lenses...
And the 50mm has great bokeh, like so many of the classic 50s. I love how the detail in the grass here just fades away.
