bullet time - multi camera photo booth questions

Posted these questions over in DIY, but guessing this is prob a great place to ask these questions as well!

Basically I'm planning building a multi-camera photobooth for some upcoming events like this http://gallery.a1array.com/rbmanyc/160514-064451

Have some questions on hardware and software:

1) cameras - considering the gif conversion will downgrade resolution, I'm thinking building this around a 12mp sensor like that in the canon XSi would be plenty. Also, the XSi was well reviewed when it was released about 8 years ago, and can be had for less than a hundred bucks each. Thoughts on this as a camera choice?

2) lens/focal length - I'm thinking 30-35mm would be the max I'd want to go in terms of width to balance between getting a decent amount of people in frame (about 4-6 max) and limiting wide angle distortion. I'll be using studio strobes and shooting at a low enough iso to keep the images nice and sharp so the kit 18-55 set on the wide end would be just about perfect with the 1.6 crop.

3) lighting - trying to decide between continuous vs strobe, but I'll likely stick with strobe because that's what I already own, and will allow a fast enough shutter speed to freeze movement at an acceptable shutter speed and aperture.

4) software - I think this will potentially be the hardest part. There's a company called Breeze Systems that makes software to both control multiple cameras (the XSi is one of the older supported cameras - which is partly why I chose it) as well as photobooth kiosk software that automatically generates animated gifs and creates links. I would rather use software that's pre-made and easily accessible rather than hiring someone to make it for me, but wondering if anyone has other recommendations?

Thanks all!

You really need to investigate using CHDK and an array of Canon Powershots for your application.  It should do just what you need!

CHDK goes far beyond what you can find in a basic DSLR.

AND many powershots do have full manual control.  Some even have hot-shoes. And for off-camera flash integration, a simple IR flash trigger from a masked on-camera flash would do the trick, no?

Trust me, CHDK, with the proper cam selection, can do just what you want. You will need the cams aligned in an arc using a simple to build holder, and a bunch of USB cords, and perhaps a bunch of AC power adaptors...

Your real issue will to be to get the resultant multiple files aligned. Stereophotomaker will auto-align two files, (which is what stereophotographers need), so there must be freeware that aligns "n" files...such as done with HDR software in hand-held mode.

I've been looking at combining Sony RX0's for a 3d camera rig... check out this article :
