The Noktons are soft wide open and do not sharpen up until f/2.0 to 2.8, so max really useable f/stop is a wash. The Norton’s do give you that nice dreamy soft look when wide open, to this is the choice. The Fujinon Zoom is quicker to use (especially for event shoots) and it is nice to have one lens set up, instead of constantly changing lenses.
That said, the Fujinon is longer and a little more awkward to use, due to its length. The Nokton’s are Primes, so shorter and much lighter. With the camera on a stick, not much difference, but shooting hand held, the prime lenses win, smaller, shorter and lighter, which adds up to a smaller rig.
The choice is up to you, how you want to use the lenses and the look you are wanting.
Cheers
