Worth Knowing
−Not truly parfocal—focus shifts noticeably when zooming full range (28mm to 135mm)
−Moderate to high distortion (up to 4.82% pincushion at 135mm) requires correction in post-production
−Premium pricing ($2,600-$2,800) limits accessibility; similar image quality to much cheaper 24-120mm f/4 S alternative
−Designed primarily for video, not recommended for still photography; heavier and bulkier than standard zoom lenses
