Rolanpro Lens Window Pillow Lens Pillow Photographic Bean Bag(With openings, must be self loading) Empty Bag-#19 Grass Waterproof Color

Semble vraiment solide, s'adapte bien à la fenêtre si on le remplir avec ce qu'il faut. Pour ma part je l'ai rempli de granulats caoutchouc. Pas simple à remplir mais on y arrive.

Great quality. The pattern is not quite as nice as their corresponding lens cover, same design. Easy to fill. I used polystyrene beads to keep it light for travel. Holds the 100-500mm lens nicely. Looking forward to putting it to use in Africa.

Just what I was looking for!

Even though it's a little small for a 600mm f/4 or 400mm f/2.8 lens, the overall design of this bean bag is decent. What is absolutely terrible, however, is that it is the exact opposite of waterproof (I purchased the "waterproof" model). I placed it on wet sand specifically to act as a barrier between the damp ground and my lens. Instead of keeping the moisture out, it absorbed it like a sponge. It actually wicked water up from the sand and became completely soaked. Thankfully, only my lens hood was resting on it, so no apparent damage was caused. If you're looking for a genuinely waterproof bean bag, avoid this product. It is worse than inadequate—it actively draws moisture towards your equipment rather than protecting it.

Great product. I use it on my car door while doing photography.
