  1. Re: Diffraction. When does it really matter with LF?

    High contrast images often gives the visual impression of "sharper" when the perceived sharpness is not real. This has been discussed many times previously on LFF.

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

    Yes Drew, for images that need most of not all of the image in focus by stopping down to f16 and smaller, not a lot wrong with an APO process lens as out of focus rendition becomes a LOT less...

    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.

  12. Re: Bellows Extension Factor & Flash Photography

    If nothing moved during flash-strobe exposure, multi flash-strobe will increase effective exposure.

    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...

  20. 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...
  21. 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.

    300mm Heliar not spec'ed ( 250mm ~ 280mm, 8x10 demands at least 312mm) to cover 8x10 at infinity, might be ok for 8x10 at shorter image distances.
