Worth Knowing
−Premium pricing limits ownership primarily to professionals and wealthy enthusiasts
−300mm focal length may be restrictive—not long enough for distant wildlife without extenders, too long for some sports applications
−Tripod mount foot is relatively short, requiring aftermarket Arca-Swiss foot for optimal tripod use
−Manual focus ring is very light and sensitive, risking accidental focus shift during handheld shooting without precautions
