why other manufactures changed from 55mm to 50mm lenses as standard normal
but heres an exercise that owners of both a MX and a SP-F can do. (I think
this should also work with an esII, KM, KX K1000 and possibly others)). Mount
a 55mm on the Spotty, and a 50mm on the MX, I used the SMCT f1.8 and SMCP-M f1.7.
Focus both on a target then hold each as if for a vertical shot and look through
both finders at the same time. You will notice that the images blend together as
if you were using a pair of binoculars. If you reverse the lens combination, a 50 on
the Spotty and a 55 on the MX this no longer works, (and it was giving me a headache).
This of course shows 1.) Why Pentax decided to change from 55 to 50 as their standard
normal lens. 2.) I have way to much time on my hands.

Oh, I believe you. I've tested it grossly for myself. Somewhere in there is the true lifesize viewfinder image. But, certainly one choice must stick out as being the most accurate choice, no? Let's see. 58mm. Yeah, that will work. 'Some time later' someone said, "Nope, 55mm is really better. More lifelike. We have all this expensive instrumentation to prove it!" Yet later, it's "Nope. Not quite. 50mm is definitely it. Change all of them to 50mm." "Final answer?" "Yes, final answer."

To grasp the true meaning of socialism, imagine a world where everything is designed by
the post office, even the sleaze.
