The Hoodman Cinema Kit Pro is a 3-part kit that includes the HoodCrane, the HoodLoupe 3.0 and the HoodMAG 3.0.  The HoodCrane is a universal hot shoe mount for LCD accessories.  The HoodCrane works in conjunction with the HoodLoupe 3.0.  When attached, the HoodLoupe may be moved up and down, or pivoted out of the way for shared LCD viewing or still shooting while at the same time providing a magnified view of your shot.  The HoodLoupe 3.0 comes in especially handy when in bright lighting conditions when the LCD screen may be difficult to see.  The Hoodman Cinema Kit also comes equipped with the HoodMAG 3.0 which is designed to fit the HoodLoupe with a tighter fit than the standard eyecup.  It also provides 3.0x magnification.
