the quality is just so, u know - plastic, i guess if i unintentionally drop the whole camera kit which the front will reach the ground first, it will be done lol, but it's still worthy for this price.... i didnt buy the 77-85mm adapter ring, but my sony 24-105g with 77mm front size seems to have a little bit vignette with this mattebox, i guess that sony 24-70za with 67mm front size fits this better
I bought this matte box to be used with a minimalist rig I set up: a small mirrorless camera, zoom 16-35 on a Speedboster,microphone and a cage. Didn't want a box with flags, and that was another reason to choose this model. Considering the relatively low price, I didn't set my expectations too high. Well... What a surprise: I got a well thought, designed and built matte box. The two trays, one fixed and one rotating (the one closer to the front lens) allow the use of a polarizer and ND at the same time, or color correction filter and polarizer, or whatever the need is for a specific situation. The design of the box doubles a a lens shade, which so far as proved very efficient and accomodating wide-angle lenses. My 16-35 on this camera is equivalent to a 22-50, and it is well protected from stray lights or flare from side lighting. I also got step-up rings made by the same brand to accomodate 3 other lenses. They are relatively cheap, and with an external diameter of 83mm to clamp the matte box tightly. If flags are needed, there are threaded holes to mount them. I use glass filters of the same brand, which have the right thickness for the tray. Synthetic/polymer filter may be too thin to fit without 'curving'.
