Fujinon W 180 & 8x10

Good guess, but the longer focal length W S lenses only came in Copal shutters -- just like the W lenses. The shorter focal length W and W S lenses were the ones that were provided with Seiko shutters.

Where was the FL demarcation? My 180mm is in Seiko. And, I’ve seen multiple 250mm in Seiko shutters.

There doesn't appear to be a hard line. The "middle" focal lengths have shown up with both Seiko and Copal shutters -- probably a gradual shift over time for each focal length. The part that I'm wondering the most about are the changes that were made to optical designs for some (all?) of these lenses when the change from Seiko to Copal occurred. Some of this might be found in some of the Fujinon literature -- with a careful reading.

Would it help with coverage in your example if one focuses a little closer in and used DoF to pull the background into focus? May not be significant. My Fuji W 360 barely covers 11x14, so besides using F16 or higher, I also try to keep it backed off from infinity if I can.

One of the advantages of clipped corners on the GG is to check for mechanical vignetting at each corner (and possible drop-off) and finding the largest aperture that can be used to avoid vignetting (if possible).

Link seems broken.

Fixed.

I deleted a post above; I mistakenly showed a negative from a Fujinon 125mm SW.

No guess. Vaughan mentioned the "S" lens element only fits the Seiko and won't fit in the Copal.

Your statement -- "WS : S = Seiko." -- is too broad, as I pointed out. Only the short W S lenses were sold with Seiko shutters. The longer length W S lenses were sold with Copal shutters -- and were not marked W C. So how does "WS = Seiko" when the shutter is a Copal?

I've purchased many WS 210mm F6.7 and WS 250mm F6.7 lenses, as well as a couple of 180mm WS lenses, all of which came in LS23 Seiko #2 shutters. BTW this is the same size shutter that's in RB67 lenses. I've also purchased Seiko #2 shutters from Japan, all were marked LS23.

Thanks for mentioning this. I've never seen anything about any Fujinon lenses in #2 shutters. It makes me wonder if these were made for a specific market (possible?) -- or simply replaced shutters for some reason (even less likely).

I think it is clear there was an empiric observation the 180mm WS only fits a Seiko shutter. S = Seiko. See post #14.
