Review on 📷 Fotga DP500III 4x4 DSLR Swing-Away Matte Box with Donuts for 15mm Rail Rod System - Sony A7 A7R A7S II III A9 A6300 A6500 GH5/5S Canon 5D 6D 7D II III IV D850 BMPCC 4K 6K DSLR Video Cinema Camera by Ryan Judy

matte box arrived on time, I like the look. It's a strong construction yet lightweight. It comes with some great features that I really like. My only complaint (and maybe it's just not designed to work at this level): I use XEEN cine lenses with a standard lens diameter of 119mm. The lenses fit perfectly in the matte box without the need for the included donuts. 50mm works great but when I switch to 24mm the vignetting gets so intense it's unusable. The frosted box opening is too small for the 24mm wide viewing angle and you can see the entire inside of the box. Otherwise, this matte box is great for the price!
