There will never be an autofocus cinema lens to begin with. To be technical the cinema lenses are a different category from dslr camera altogether. Until today when you uses Red camera or Arri Alexa,all lenses strictly on manual focussing so it's viable to use those lens on various camera body and to build the best optical lens already took up a lot of weight and volume,so it's impractical to slap another motor that are proficient and silent in every single focal length.Furthermore until today the technology isn't there yet to replace a human focus puller as the calculation simply couldn't keep up with the precision of a human hand-eye tracking a moving subject.The closest autofocus you can get is on a motion control rig but all point to point focus are pre-calibrated during rehearsal.Just to be clear.
Chroma key (green/blue and in rare cases red) only happens efficiently during the mid-90's as it uses COMPUTER software to do clean-up.Before that all either practical optical illusion or optical background projection or frame by frame painting/erasing or even sandwiching two different negatives to make a single negative.Hence you saw a different exposure of the attacking bird to overlap the background plate that gives away the crude outline.Pre Star Wars era,majority of effects shot are limited only to static framing (not counting jittery stop motion) as fluid 3 axis movement simply unfeasible before the invention of motion control rig when comes to compositing elements.
