A Canon FD 50mm f/1.8 lens mounted on a Panasonic GH4 with our Canon FD to Micro Four Thirds DLX Stretch adapter. DLX Stretch adapters pack three functions into one adapter! Mount eight different lens mount types onto Sony, Fujifilm or Micro Four Thirds cameras, adjust the back focus of your lens with a built in helicoid for monster macro shots, and drop in three included ND filters into the back of the adapter to shoot shallow depth of field or long exposure photos even in bright sunlight! - #CanonFD #vintagelens #retrolens #GH4 #MicroFourThirds #Fotodiox #lensadapter #DLXStretch #CanonFD50mm #FDtoMFT #camera #retrolensonMFTcamera #FDtoMFTlensadapter #macrohelicoid #helicoidfocus #productphotography #PanasonicGH4 #SonyA7RII #macro #NDFilter
