Vimeo member HDSLR GEAR has a great review on the new gen TrustMT MatteBox. [Thanks Joel]. For those who are new to shopping for a MatteBox, this is a great video explaining options and features some lower end MatteBoxes will lack. Features such as a basic filter tray (Some don't have any. This has more than one), Rotating filter trays (important for CPLs or ND Grads filters), swing away arm (for faster lens changes), and quick rod mounts (not threaded to lens, so you don't have to worry about fit). When considering Features + Build Quality + Price in a MatteBox, the TrusMT brand always comes up in conversation. You can find the various TrusMT products at their store (click here).

Just a quick over view of what to expect on this dslr matte box. This particular one is fairly well made with just a few quirks, but it's definitely a hundred times better than the cheap plastic one floating around. If you're really into the aesthetics of your rig, I suggest going for this. The FilmCity MatteBox is mostly metal including the flags, top sunshade, 15mm clamp, and donut ring. The hood itself is the only thing made from hard plastic.
The flags on the Mattebox will not fold up for storage, but it breaks down quickly to be packed away. The top flag will tend to get loose with constant positioning and would require the allen key to re-tighten. The side flags can easily be tightened by hand through the thumb screw. The single filter slides in an out with ease, and can be locked down quickly. It does not rotate so it's not something to be used with a CPL. The mattebox does not have a swing away design, so to make things simple, keep it at the end of your rail set. Yes it does require rails to mount. If you've got the money, I suggest going for the more expensive versions with a swing away design and the ability to rotate filters. One that some consider is by TrusMT found here: Trusmt DSLR MatteBox Carbon Fiber or Aluminum.
Considering the prices of current matteboxes, overall the FilmCity is one of the cheapest with decent quality build (again much better than the uber cheap plastic one). Can be found on eBay (click here).

I've been pointed out to this TrusMT company for quite some time. I didn't bother attempting to decipher the language on the main website and just believed they were just retailers for Letus equipment. Turns out I was wrong, and they are stamping TrusMT brand logos over what 'looks like' a Letus Aluminum Hawk VF, and DSLR cage, and Shoulder Rigs. I don't think it's up to the same standards or build quality. I stand corrected as it's not a retailer selling the Letus Brand, and for the first time they've shown up on eBay with a low sticker price into the DSLR market. My guess is they won't be online for long because of the design resemblance, but we'll have to keep an eye out to see where this goes. They've actually been selling around the UK for some time under that brand, but maybe not this 'other' line of mocks. Can't go wrong with the Letus stuff, which can all be found here: http://LetusDSLR.com
