Backfocus Setup

  1. EF Lens to ASI Cameras (44.0 mm, without filters), base: 17mm, or 10, 10.3) +
    1. with ASI FW: Thick EF Mount(10.3) + Thin Adapter(6.4) + 1.0mm spacers + Filter Wheel(20) + sensor(6.5) = 44.2mm
    2. w.o ASI FW: Thin EF Mount(10.0) + Thin Adapter(6.4) + 10mm extension + 11mm adapter + sensor(6.5) = 43.9mm
    3. w.o ASI FW: Thick EF Mount(10.3) + Thick Adapter(15) + 1.5mm spacers + 11mm adapter + sensor(6.5) = 44.2mm
  2. Note that adding filters will add length to back focus requirement
    1. Use 11.5mm extension instead of 10mm
    2. add spacers
    3. buy 2 or 3 mm T2 extension tubes
