I went through three Pentax Spotmeters over thirty years.
The first generation (the one with an analog dial) taught me the beauty of precision exposure measurement and it clearly explained the meaning of the term "exposure latitude", right there on the dial.
The second one, my first all-digital, somehow slipped into the Fraser River late one January night. I'm sure it's still there.
The third sits in my "retired items" drawer - fond reminder of my days shooting aerials for the movie business. I loved that meter. "The Truth Teller", I called it. My backup, never used, I sold when I retired.
Movie producers are rather intolerant of exposure errors, especially helicopter aerials, which are quite expensive to implement. You can not guess, you can not bracket and you can not screw up. Period. The Pentax Spotmeters never let me down.
