Designed specifically for the Canon RF 600 f/4L IS lens, the LensCoat Lens Cover, in RealTree's Max 5 camouflage pattern that blends into your surroundings when you're out in the woods or on and near water, provides protection for your valuable gear. It safeguards against scratches and minor impacts, while offering a thermal barrier to keep your hands warm in cold conditions. The cover is easy to install and remove, sliding on like a sleeve and leaving no residue on the lens finish. It has clear, flexible PVC windows over the auto focus and image stabilization controls to maintain full functionality.
