@Ian Grant "These wide angle lenses 75mm or 90mm are not really suitable for swapping back and forth between lens boards/lens cones if you've ever unscrewed the rear elements to mount the shutter you'd realise there's a higher risk of potential damage to the glass." Agreed.
Your two images have backed up my plans to shoot 6x17 a lot more, the chance finding of Center ND filters has been another
If you're ever in the UK I can show you near identical scenes In my case canals as the rivers are faster moving and not tranquil but around Norfolk where Tom lives that would be rivers . . . . .
@Ian Grant Good!! I'm glad to be useful
My sister lives in Manchester. I visit her once a year !!! I love it.
I've one question ... what do you think of Grandagon-N 75 6.8??
I've only used 75mm f8 & f5.6 Super Angulons but have used 90mm f6.8 Grandagon-N for over 30 years, the 75mm Grandagon-N will be an excellent lens and just as good.
