I just love the M20/4.
While lenses get more and more macho, I am relieved that there are such lenses like the M20/4 that are a good small size for my preference of an easier to carry around setup.
Finally got to trying out the other mode dial today.
Once I tried it, I just can't believe how easy this setup is but no one thought out it until Pentax offers it on the K1.
Basically, I can choose a function that I used often and want fast changes and set that on the mode dial, allowing it to be then controlled easily/fast with the 3 scroll wheel.
Eg.
1. Set to EV +/-, then the 3rd scroll wheel becomes a +/- ev compensation selector.
2. Set to Bracketing, then the 3rd scroll wheel becomes a bracketing type selector.
