While Sony has been tightlipped about the specifics of their FE 400mm f/2.8 GM prime telephoto, they have gradually allowed more access to the prototypes. This video sums up basically all that can be said about the lens before actually holding and shooting with the thing.
Sports Photographer and Sony Artisan Patrick Murphy-Racey was recently at the Kando 2.0 workshop where the FE 400mm f/2.8 GM was on display in a look-but-don’t-touch security case. Finally we get close-up looks at the switches, slide-in filter, and subtle design features while Murphy-Racey goes through the purpose of each one by one.
One mystery that remains, however, is the purpose behind one of the panels on the side of the lens. When questioned about its purpose, Sony engineers told Murphy-Racey “it’s a secret.” In the video he said he believes it to be a USB port for easy firmware updates. Time will tell with this one. What are your guesses?
Check out the full video above for more details that you may have missed in earlier sightings of the lens. The slated release date for the FE 400mm GM is September 2018 with pricing still unannounced.
