If this really works, then why do we need fast lenses? I've seen some graphs which report a resolution-loss when the IS is on, but does that really show versus a "normal" lens which is all shaky at slow shutter times? <<< My response has nothing to do with the shorter IS lenses but everything to do with the longer ones. I've found that for just about any situation other than at airports or political events <g> the shoulder stock gives me as much stabilizing effect as I've heard claimed for IS technology. For example, 1/60 sec for the 280 or 400, 1/125 sec for the 560 are very usable shutter speeds providing excellent results. I haven't tried any shutter speeds below 1/60 'cuz I'd get too much subject motion and besides the shutter on the SL isn't continuously variable between 1/30 and 1/60. Advantages of the shoulder stock include using the stock with any lens that has a tripod socket and not having to engage/disengage or switch IS modes. Disadvantages are the bulk of the stock and its superficial resemblance to lethal weponry! Certainly there are situations where IS is benefical but it's not a cure for all our dim-light problems.
