Because our shot lag tests incorporate a significant distance refocus and exposure adjustment -- we begin with the lens adjusted for an object close to the camera, out of the range of the lights before focusing on the more distant, differently illuminated scene -- how fast the lens drives to the new location substantially affects lag time. Since the D5200 has no built-in AF motor, that performance will be heavily determined by the motor in the lens, and in this case, the 18-55mm kit lens drives relatively slowly. However, our shot-to-shot times, which don't require any signficant lens movement or exposure adjustment, do reflect the speed boost.
