I was talking to someone the other end of our street yesterday and he waxed lyrical about his heavy Nikon F, and I said yes but I far preferred the ergonics of Pentax cameras. I sold my Spotmatic F and S1a's years ago to move to K mount, I was shooting rock concerts professionally very regulary as well as location shots for a record company.
More recently I've gone back to Spotmatics, an F an SP and and SP500, also an SV but hey that was £10 with a lens and meter and fully functional.
In comparison modern cameras around 20-25 years old deteriorate, the coverings go sticky, I've binned lenses that were once expensive what had been a nice Sigma telephoto zoom, I was given it never used it but one of my nieces had for a few years. It was the same with the Nikon 401 camera.
What's the life expectancy of a camera now, 10 years roughly, but hey I use camera made late 1800's and early 1900's and theres not these issues. And I could buy older
Pentax cameras were once built to last like a Leica, the pileof plastic my sister gave me won't last, it was an insurance replacement for an earlier model.
