Hi,
maybe a stupid question, but my knowledge of this area is poor so...
Why some lenses are still produced with manual focus?
Example: samyang, Voigtlander...
Is it that hard to build an autofocus lens compared to a manual one???
have DOF scales so you can actualy set the hyper-focal distance and do zone focusing. Either of which is faster and more accurate than the best PDAF systems ever made.
Oly makes two AF lenses with DOF scales but they are about ten times more expensive than a typical legacy manual lens.
