For 35mm stuff I like my M2. Then, should we even mention SLRs, I like my Nikon F2.
I like to hike and the M2 is reasonably lightweight and the only time I have ever had trouble with it, was the time long ago, when I forgot to put film in it (Oh yes, and then there was that embarrassing lens cap issue.........).
The F2 has never had trouble in the 30 years I've owned it. I suspect it never will in my time. The meter needle isn't even jumpy. If the camera were to fail for some reason, I wouldn't hesitate to pay to have it repaired or overhauled.
For 35mm these cameras are more than enough for the likes of me. I've had and used these cameras for a long time, but I realize that in truth the older I get the more I realize how little I know about how good they really are.
