I have read countless posts on the forum for bashing this lens or that lens because it has "lens creep". I personally own the "Mother Of All Lens Creep" lenses, the Sigma 50-500 "Bigma"... to be fair, it doesn't just creep, it RUNS out to the end if you don't lock it down. I also own a 18-200 VR that is famous for lens creep, although the one we own doesn't do this at all. I have heard that most of them do, and have no trouble believing it. I had several film camera lenses "back in the day" that did the same thing. I find that lens creep doesn't bother me much, because it generally only happens (in my experience) on long telephoto zooms when shooting down at very sharp angles... and one doesn't generally shoot down with one of those... Obviously, if a lens were being used for serious macro work and it creeped, that would be a real problem... but I can't imagine why anybody doing serious macro work would be using anything other than a prime to start with (especially since there are some VERY inexpensive excellent prime macros out there). If a lens "creeps" when it is hanging on my strap, I just twist the little ring and it uncreeps. No big deal. On the Bigma, I just click the lock, and it doesn't creep. One has to expect a LOT of design trade-offs in a 50-500 10X zoom (something with that range is not going to be as good at anything as shorter-ranged zooms), so potential Bigma owners should just learn to deal with the creep. I am curious to see how much lens creep actually bugs the rest of you, and why it bugs you. Would a bit of lens creep stop you from buying a lens that is otherwise something you would want to have in your bags?
