@Netspot, @Vitaliy is correct we are now discussing too many other parts.

Simply ... raise the camera.

@kavadni On the pic, I only inserted the lens into the matte box only to show that I'm missing a centimeter upward from the rod clamp (of the MB) or downward from the frame of the MB, the rods of the rig are not inserted in the rod clamp of the MB because I can't. And so my problem is that the camera is not high enough and the adjustment pushed at its highest point for the lowest position of the matte box. Sorry! I think it's quite hard to follow. So to summerize I need either to rise up the DSLR or lower the MB (I think I'm being even more confusing). That's why I'm thinking to install the MB on the vertical pair of rods on the side of the swing-away mount using the following: http://goo.gl/M25ROa

Consequently I'll be able to adjust the C-Shape mount and then play with the adjustment of the MB.

Thanks for your help and your patience

@netspot

There are standards for rod/rail systems. See http://www.ocon.com/inspiration/labs/rod-standards-explained/

Some of the cheap brands don't adhere to this. Check which of your gear does not and adjust that piece. It will make things work better together.

@Netspot.

I had the lanparte height adjustable base plate and got rid of it, for me it's overkill in size for a DSLR.

I use the same baseplate you have for my DSLR's.

I also have industry standard height MB and had the same issue you have. My solution was to remove the top plate of the baseplate, get some longer m3 screws. And raise it to position the GH2 optical centre at 85mm with spacers.

For the GH2 you need to raise the camera by 13mm to achieve 85mm optical centre.

Here is the mod: that's actually a 10mm spacer, I was able to lower my mattebox x 3mm, and 10mm material is easy to find.

@Vitaliy_Kiselev @vicharris Sorry for the size. The issue with an adjustable base is that if I rise the DSLR by 1 or 2cm, the follow focus will not have an optimal position (see pic attached).

@NetSpot

It is not MB fault at all. And why you need such strange solution? It is fault of your camera mount (btw one of the reason why you never seen it on deals here). All you really need is to find proper adjustable base (even without rods). And they are cheaper than C bracket. Problem with bracket on rig it's weight mostly, and you anyway will get base, sooner or later.

Also, I specially asked not to upload photos of such size (really, even 400px are enough in this case).

@NetSpot

No, all the knockoff versions. Not RedRock. I'm sure there's is fine. As for your problem, seems like there's an easy fix and I'm sure V will figure it out.

@vicharris No I only meant up and down adjustment for the moment, but horizontal adjustment is something I'll have to figure out with a C Shape stuff. and What the f**** the RedRock is poorly buit! At the price they sell it! Never tried Redrock and will never do.

@NetSpot You mean left to right adjustment right? Meaning your lens does not center that way instead of up and down? If so, that's the same reason I sold my RedRock Swing out knock off matte box. It's re branded by many companies but it's so poorly built, the donuts would fit for some lenses. If this is your problem, that's one of the tradeoffs for a mattebox so cheap. Bummer but that's how it is. Poor QC.

Sorry, I didn't know what was the proper size to publish a pic, I did an export at less than 2MB. The issue with the Lanparte height adjustable baseplate is that if I lift up my camera I will lose the proper position of my FF. The vertical adjustment is already at his maximum downward. However I found the Fotga DP500II C Shape height adjustable bracket to be an option. Can I post the ebay's link?

And thank you very much for your quick answer.

@NetSpot

Can you, please, resize photos before attaching?

I'm really happy with fotga build quality and these DP 300 matt boxes look very interesting and maybe good value. Would be good if Fotga eventually had some shots of there rigs with everything mounted. I basically have a DP 500 set up with C bracket and was wondering if the M3 swing away matt box will compliment it, so instead of taking a punt maybe I'll just go for the M2. I also like the look of the DP 300 bracket, and if it is wider than the DP500 bracket I would certainly grab one, though I can only see one 1/4 " mount ?

Yep, even the Cinematics dies this.
