Hoodman Cinema Kit Pro on Nikon D800E - solution for MF lenses with front or rear focusing
Nikon D800E and lens Voigtlander APO Lanthar Macro 125mm f/2.5 SLI on Tripod equipped with with Hoodman Cinema Pro Kit mounted on hotshoe flash against LCD screen. Taken with my Olympus Camera OMM-D with 45mm f/1.8 Olympus lens at ISO 1600, f/2, 1/100sec.
After struggling many moons on how to obtain sharp focus with manual lenses on this 36mpixels camera, using the non-precise green AF assist LED in the view finder, I decided after testing everyone of my lenses that a few would never work correctly with this generation of AF system. My search for an alternative focusing system led me to believe that only the focusing on the final sensor image itself would match the high resolution focusing requirement of this camera. It is the trend taken by most mirror-less cameras with an Electronic viewfinder that gives the final sensor image (NEX, Micro four third cameras ,etc....).
This system shown above from the Hoodman corporation is perfect for still photography like landscape of Macro of flowers/objects. Once installed you just turn the D800E into liveview mode for still photography and use the + button at the rear left of the camera body to magnify as much as you wish: then you fine-tune the focus visually. Voila!
By using the live-view mode and the magnification on the LCD screen, I can now nail every time (100% success rate) the precise focused zone. My Voigltander 125mm f/2.5 (shown on the above picture) can finally be put to good use. Without this system and relying on the green dot, this lens as well as my Nikkor NOCT 58mm f/1.2 on my D800E camera can back focus up to 30 centimeters at a distance of 5 meters, which ruins most portrait shots
The cinema kit is not cheap ($189) and comes with the loupe, arm mechanism with hot shoe adapter that slides inside the camera hot shoe receptacle.
And yes, for moving subjects, people, sport, get a good AF lens like every normal person... :)
