The ocular's job is to bring the reticle into focus. The objective's job is to bring the image of interest into the same focal plane (or as close as possible) as the reticle's position. If all is adjusted and working correctly, the reticle is in sharp focus and the image of the target is also in focus because it resides in the same focal plane as the reticle.
