I have been using a 24/2.8 AI-S recently and have not noticed much flare, but then I got the lens in the middle of winter and have been out only a few times... Now, it is interesting to hear about a persistent flare problem with the 24/2.8D from two users, because I've been thinking about getting the AF version. Any insights as to whether this is a problem specific to the AF/AF-D versions of this lens?? Does this mean that the AF version of this lens would make a rather poor substitute for the MF version, since the MF version is already an excellent performer as to sharpness and contrast??? Flare is not something I'd like to live with especially in a wide angle lens. Would I regret going AF with this lens?
