I am looking for a comparison of the 7 series vs. the Konica Auto S2, specifically their viewfinders.
How do they compare? And is the 7 series really more reliable?
Don't know if my comparison is good, but:
S2 and 7s finder is very similar in size, with perhaps an ever so slight advantage to the 7s.
The clarity is about the same too, with how lucky you have been in getting a clean one and how far you are willing to go in cleaning it, being much more important.
The S2s party trick is the adjusting finder lines, and the top lit exposure scale.
That
is really cool, but does it really aid usability?
What's more the rangefinder mirror in the S2 has a penchant for spontaneously falling off, due to bad glue being used.
Amazingly I have never found a 7s that didn't work perfectly or almost, I have owned about seven or eight. The S2 on the other hand I have five of and all of them has some problem that makes them unusable (going to try the shutter naphtha trick in the video though).
