3x3 Matte Box Package for DSLR Cameras, Includes MB3485S 3x3 Hard Shade Matte Box, ADU085-D45 Adapter Ring, RST2550 + R156025 Front Bracket

It's compact and fits up to a 77mm lense.Biggest lense with adjustible ring is 67mm.Decent rod clamp, but plastic leaf bolt.Light weight and practical.

Literally the worst transaction I have had on Amazon.This matte box looked like a decent deal. I bought it to use with my Canon EF 70-200mm f/2.8L IS III USM Lens, which has a 77mm front diameter. This product claims to accept lenses up to 80mm.This did not fit my 77mm diameter lens.I returned it, and ADORAMA did not give me a full refund.I asked why, and they said that I did not return the product in the "original manufacturer's packaging".The matte box did not come with original manufacturer's packaging. It was in a plastic bag, in an ADORAMA box. Nothing else.I told this to ADORAMA. They asked for photos. I gave them photos.They said they "checked with shipping", and said that I was lying.This conversation went back and forth for several emails, and they repeatedly ignored me. All of this so they could keep $27 for something that doesn't exist.Adorama used to be a decent option for video production products. I'll be taking my future business to their competition, and suggesting that others do the same.*** UPDATE ***After writing this post, they refunded the final amount.So, icing on the cake, they wouldn't budge until they got called out publicly on their extremely poor business acumen.Never again.
