So which is responsible for the AF performance? Is it the lens? the camera? or both?
and how does each influence the AF performance? Inquiring minds want to know....
Both. Some AF lenses have lighter and smoother AF mechanisms might AF faster. Some AF bodies have stronger AF motor might AF faster. Some AF bodies have better algorithms might lock focus and track moving subjects better.
