the Pentax-A SMC 35-105 / 3.5 and the Canon FD 35-105 / 3.5 are two zoom lenses with manual focus generally well regarded. The Pentax lens has the nickname "Stack of Primes", while the Canon lens has the reputation of being as good as the L glass, an "Honorary L", so to speak.
How do the "Stack of Primes" and "Honorary L" goals compare? Acuity? Color? Contrast? Explode? Bokeh? Quality of manufacture? Handling? Etc.
There can only be one.Which one should it be?
