Luma's optitrack studio ( new cgsociety article )

NaturalPoint's cameras are hopefully revolutionary ( beside the incredible pricepoint )

I priced a couple of the bundles compared to buying all the pieces seperately and there seems to be no price cut for buying the bundles.

Either way the s250e ( the fastest camera )Arena bundle's cheapest option is the 12 camera system
at $25,000

That is the same sytem however in the luma studio ( 12 camera s250e ) sans the facial cameras or any virtual cameras.

Since there seems to be no price benefit to the bundles, ( and since you can build arena bundles with just 6 of their cheaper cameras )
I imagine building a smaller custom bundle and Just upgrading that yearly till reaching 12 to 48 cameras would be more affordable in the long run. ( if the cameras reduce in price )
On the other hand it does look like they have had cameras that have become obsolete as well.
They have a used marketplace in their forums but only the cheaper camera bundles seem to be up for sale.

The tracking software
Arena software
and Facial capture software
are all priced seperately.
