Hi Jonathon,
The 100 f/4 is optimised for macro work. However, the A 100 and F 100
macros are faster and perform better for landscape work. If macro
performance is not required, any of the 100/105s will do. If, and I say IF
you can find a 105 f2.5 K, get it! It is one of the finest. An option would
be the screw mount 105 SMCT or Super Takumar. It is the same lens in a screw
mount. With a K/m42 adaptor and stop down metering, it will deliver the same
performance.
