The Dynax or Maxxum or α-9 or Alpha 9 was Minolta’s best and last professional film body, originally released 1998, it was their best 35 mm autofocus camera, featuring an unbelievable 1/12,000th shutter speed. It was constructed with a zinc and aluminium die-cast frame covered with 304 stainless steel, which was very uncommon for cameras. I also have the vertical control grip (VC-9) featuring the cameras’ basic controls. The best and last 35mm SLR (Single Lens Reflex) camera ever built. Very lucky to have this camera in all three SSM versions, Alpha, Dynax and Maxxum.
With carbon fiber reinforced shutter blades, and a frame rate of 5.5 frames per second. Some of the earlier versions did not come with support for the SSM Super Sonic Motor lenses, however, upgrades could be completed by repair shops at that time. Although the Sony engineering team was unable to match the engineering miracle required to have a mechanical shutter fire reliably at 1/12,000th of a second, this camera really inspired the Sony ILCA-99M2, Sony’s last real DSLR camera.
