Hi,
The biggest advante with a multicamera setup is the photgraphic way of capturing, meaning you can freeze the reality within miliseconds... With Eva from Artec you need to sit still for some time, even though the results are good enough for 3D printing. I am running a studio with 42 Canon 600D, ( will get more soon), its tricky you really need time to understand all possibilities you have, but out o my experience Artec for mobile solution ( you can visit the client - big advantage) but for a studio solution, the gold standard is a multicamera setup...
good luck, all the best Andreas from fabberlounge
