Question: I'm new to the world of matte boxes.  Where can I get filters that will fit into this?
Document: This matte box is excellent, great for the price! Definitely an alternative for those who can't afford name brand matte boxes that cost thousands of dollars! I almost believe that this might be better than some of the major brands like Redrock Micro! I rated this item a 4 because when I got it there was a little scratch in the inside right corner of the matte box. When I purchase something new, I expect it to be perfectly manufactured and flawless!
Let me start by saying it does work. I do use it and it's almost fully functional. However, there are several problems.1. The center of the matte box does not align with the rods it's supported by so the lens does not fit in the center of the matte box. I'm not using any super wide thread lenses so it doesn't bother me too much but it gets difficult when using the donuts.2.
I don't care if it only cost $10...NO SCRATCHES PLEASE. I WILL BE THE ONE PUTTING SCRATCHES ON IT...NOT YOU. I did set it up to my camera and it's quite difficult to get it to line up evenly to the camera. Is this another result of the low cost? Or is it just me not setting it up right?One last thing: it's heavy. I'm not sure a matte box really needs to be this large for a DSLR camera.
The main compartment is made of plastic, so it can get scratched up.4. The swing away has a little bit of play5. The donuts for the back can fall out easily and do no fit snug and tight. I said &#34;to hell with it&#34; and do not use them anymore.6. You should use automatic lenses with this or a follow focus system. Turning the focus ring manually is a nightmare.
Be forwarned that there are no instructions as to putting this together and if you have not put a matte box together before it may be a little tricky but after a few tweaks you should get it. The customer service at Red Star is incredible so if you do get stuck I'm sure they will be quick to respond as they have been with my questions.
It's too far to the left by about a 3rd of an inch. But the donuts fit sloppily enough to still block the light from the back ok.It works. I'm gonna keep this one, but I'm NOT impressed. I feel like I got what I payed for, maybe a little less. If there was something better in this price range, I'd return it again.
I researched affordable matte boxes for my 5D2 rig , & eventually settled on the Red Star. It arrived V quickly & well packaged. No instructions, but it's a 5 minute job putting it together. Big & solid. Looks the business & does what it's supposed to do. The overall quality is pretty good for a knockoff. A bit of fine tuning & it's good to go. V good value.
This is a great piece of equipment. The build quality is excellent. The main reason I bought it is that the Matte Box swings out allowing me to change lenses on the fly. French Flags are Metal not plastic. There is no bottom French Flag. Fits well on my 15mm rod system. I don't use filters with it yet so I can't speak to that.
I don't usually write reviews but this one deserved one. I wasn't expecting the quality for the price. It is very well made and very sturdy. I have a friend that has the redrock matte box and they are very similar, he couldn't believe how cheap it was. The only issue I had was the lens rings that come with the matte box didn't fit quite snug but not a deal breaker. I would highly recommend this matte box!
For some strange reason, the talent  is more excited and gives you a better performance when they see the Red Star DSLR pro II MatteBox! I already have 3 lens hoods, and many filters for my camera. that does not cut it when you're out in the field. You'll learn that video production is all about perception. Another thing that i liked about this mattebox was the 16:9 matte frame in the front. This is what sold me because the cheaper matteboxes did not have it.
Answer: Just search for 4x4" and 4x5.65" filters.
