  1. Re: Aspherical, Apo(chromatic) & ED (extra low dispersion) lenses - whats the differe

    Marketing Fluff, no single descriptor from this list can make your image better on it's own and much depends on how these optical design tools are applied to meet the goals of the optical designer.

  2. Re: Bellows Extension Factor & Flash Photography

    If nothing moved during flash-strobe exposure, multi flash-strobe will increase effective exposure.
    Very common practice back in the days of high power required studio LF photography.

    Re: (possibly) taking the large jump

    The Very Biased Opinion would be the Sinar system. Sinar Norma is a much nicer camera than the F, F1 or F2. The Sinar P is an excellent studio-maybe but iffy of outdoors camera due to bulk-weight...

  9. Re: Seeking a newer 4x5 camera for mostly landscape

    Go directly back to the lens choice and image goals, that essentially determines what cameras can be chosen.

  10. Re: Sinaron 5.6 / 210 mm Smallest Aperture

    LF lenses in shutter use what are essentially generic shutters that are not specific to any given lens formulation-design. This allows some LF lens cells to be transferred to a new shutter if needed...
  11. Re: Sinaron 5.6 / 210 mm Smallest Aperture

    Re: Shutter for Heliar 300mm 4.5

    If the Svedovsky 8x10 works with the Sinar shutter, get a Sinar shutter, select your optics and make images.

  33. Re: Disastrous Consequences (solved: fog with Intrepid lensboard)

    Cost to water jet cut FR4 or aluminum is about the same. Since the FR4 is coated, finishing cost would be very similar. Very possible raw material cost would be more for the FR4 as non-copper plated...
