My experience with the Fujinon-W is that they are very sharp and contrasty.
Some pictures benefit from this and some don't. The Fuji lenses can be a bit clinical and lifeless just because they are so sharp and contrasty.
If that applys to you I don't know. It all depends on you personal style and subject.
It will be very different from the Xenar thats on its way.
My guess is that you will not be disappointed if you buy it.
The only reason I raised the question of repairing Seiko shutters was that when I had to have the Seiko shutter on a Mamya TLR lens repaired 5 repair shops said it could not be done due to unavailability of spares.
