For 7x17 I use:
600mm Fujinon C, f11.5, in Copal #3 shutter
450mm Nikkor-M Sinar f9, in Copal #3 shutter
300mm/12 inch Wide Angle Wray f6.3, barrel
300mm/12 inch Gold Rim Dagor f6.8, in #4 Ilex shutter
273mm/10 ¾ inch Wollensak f6.8, in Pi-Alphax shutter
250mm/10 inch Kodak Wide Field Ektar f6.3, in #5 Ilex shutter
I had a 210mm SSXL but felt it was too wide for my vision and sold it.
My most commonly used lens is the 300mm Dagor.
