Call me fussy, but I hate to see misinformation. The AF 84/1.4 does not have aspherics. It has internal focusing (IF) and close range correction (CRC). The manual version also has CRC, which maintains sharpness from infinity to closeup, and eliminates the need for expensive aspherics. Canon's 85/1.2 has aspherics to maintain correction with the faster aperture. Roland.
