On a 4x5-based DOF adapter rig, f/2.5 via an Aero Ektar, f/2.8 via a Xenotar, or f/2.9 via a Pentac gets you f/0.67, f/0.74, or f/0.77 equivalent aperture emulations, respectively.

I will try adapting a Rollei Heidosmat 150mm F2.8 MC. It's as cheap as it goes and the next stop would be some 4.5 Tessars of which there are a million or some many cheap Fujinar f4.5 (usually better crafted). But f4.5 is more like f1.2 and thus less interesting. I think f2 is where 4x5 gets funny with f0.5 view.

Glad you mentioned the f/4.5 Tessars - I happen to be researching ones to get for 8x10 (I may base my rig around 12x12" Fresnels and include a way to shoot 8x10 film without them). To cover 8x10 I've found out I need about a 12" or longer FL f/4.5 Tessar-type. The point of entry seems to be about $250 for one in rough shape whether it's mounted in a shutter or in a barrel. The ones I know to look for so far are:

  • Kodak (via an Anastigmat/Anastar/Anaston/Ektanar/Ektar/Ektanon - some of these are marketed as projection / enlarger lenses, and the Ektars are not as cheap),
  • B&L (via a Series Ic)
  • Schneider (via a Xenar),
  • Ross (via an Xpres Anastigmat),
  • CZJ (of course),
  • Ilex (via an Anastigmat)
  • Wollensak (via a Velostigmat or Raptar II - OK these don't look as cheap)
  • Gundlach (via a Radar Anastigmat)
  • Fujinon (via a Fujinar - some are enlarger lenses)

What about Industar 13 or some other other lesser know brands? Of course, this is for adapted glory, not product photography or national geographic.
