Alexa plate version 2 for back haevy setups

Sal (who used to work for Otto & is now on his own) machined a very nice plate for Alexa that Otto provides. I wonder if he is able to make that now, or maybe the design belongs to Otto.

 

Matthias's plate looks interesting,as does the other one shown.

 

Matthias, I'd be interested in a plate,as yours seems lighter & shorter than the rest, which are 2 good things in my book. I have your original small plate, but it scares me with the codex on the back.

 

Can you confirm Janice's question about the kipp handle. Is it possible to make the bottom flat?

 

Thanks for your relentless R&D on this kind of stuff. It's very cool of you.

Mark, yes, Sal does as discussed in this thread (discusses a lot of mounting options). I own one of Sal's plates and a Baer-Bel CamTec plate. I like both of these independent options/solutions for two reasons: they are both dovetailed for a PRO DB, giving maximum fore-aft travel (front and back heavy cameras would both fly well) with the absolute lowest hight possible for mounting an Alexa (no height increase from stacking multiple plates, riser block, etc.) Second, like Matthias' plate, they both secure the Alexa at two mounting points, which most have found essential for stability and vibration elimination.

 

Folks, I know these plates are expensive, but the Alexa is (thankfully) here for awhile, and thankfully folks like Matthias, Sal, Greg, Markus, etc. have spent the time, energy, and money to give us not only solutions, but various quality options to fit our differing needs, likes, and demands. Cheers!

Here is a photo of a real setup with a codex. It is balanced.

 

The bracket weights roughly 250g / 0.5lbs

 

The setup is light in the front: ultraprime lens, only one focus motor, 2 stage LMB-5, no filters, no cinetape, no mdr.

In the back, there is even a bebob hotswap still on the camera, that keeps the codex 1,5" further out as it should be. Unfortunately there was no codex mountig brcket available, so it is fixed with a focus rod and a motor brcket and some rubber ties. Not ideal, but good enough to test the balance.

 

If you look at the photos in the other back-heavy thread, no one is that far to the back.

I´ll also offer an extension kit that allows mounting the dovetail further back. Still using the sony hook.

The new bracket is good for regular and front-heavy setups as well, as it uses two mounting points. This will give more stability and reduce vibration.

 

This pic is for demonstration only. Setup is not balanced!

I see that kip handle and back section getting in the way

Of putting the plate back further

What kind of Black Magic is this???

 

Sorry to backtrack to Janice's original post (part of it)... Is there a part that just pops off, to allow that lower section to come off for X-tremly back heavy cameras (as you have demonstrated)?
