(*1) When shooting with wider aperture setting, image quality may degrade on peripheral part. Use smaller aperture setting.
(*2) Minimum focus distance gets little bit longer. Commercially available close-up lens No.2 like "Canon Close-up Lens 500D/72mm" etc. would be recommended to attach on the lens front to compensate it.
(*3) Auto focus (AF) only. For manual focus operation, optional "MRS Control Ring(60/60II/100UII/100UIII/Olympus 50)" and compatible "Magnet Ring" is necessary.
(*4) When shooting at zoom wide end with wider aperture setting, peripheral part of an image may get degraded. Use smaller aperture setting.
(*5) Supports zoom operation. Manual focus (MF) is not supported and only auto focus shooting is available.
(*6) "Shade Sponge D70" is attached on inner side of the Dome Port 2 or Dome Port 115 to block built-in flash light to prevent the flash light from exposing on an image. The optional "Zoom Gear AT-X107" (to control zooming), comes with a Shade Sponge D70.
(*7) Non USM old style lens.
(*8) "Shade Sponge 7mm" is attached on inner side of the Extension Ring S to block built-in flash light to prevent the flash light from exposing on an image.
(*9) "Shade Sponge D80" is attached on inner side of the Dome Port 2 or Dome Port 115 to block built-in flash light to prevent the flash light from exposing on an image. The optional "Zoom Gear 8-15" (to control zooming), comes with a Shade Sponge D80.
** "MF Port"series ("MF Standard Port 2"/"MF Wide Port"/"MF Flat Port") or "MF EXT. Ring M" can not be attached on "Extension Ring" other than "MF EXT. Ring M".
