Is there a great amount of quality difference in shooting a 4TB series vs a 6TB series for the finished product? Is there much difference in time to set up? how long does it take to shoot a room inside? Are most people using flashes, or adjusting exposure times to capture ambient lighting?

I work in real estate and currently I am producing archaic single row panos, but I am upgrading everything to shoot full 360x360 in the next few weeks.

I'll be shooting a Fuji S2 Pro (friend upgraded to the S3 and doesn't need the extra body), Manfrotto 303sph, sigma 8mm, mounted on a Manfrotto 161MK2 with the leveling base.

Welcome to the Forum Blacktip.

If you are using a Sigma 8 then it is only 4 drum +Top.  You will get the tripod head in the 'Bottom' image unless you dismount the Fuji and take a straight down shot at arms length +same elevation as the pan head.  Yes you will get your feet in the image, but they come out during stitching

The 6 shot is FULL frame.  I think it was setup for the Nikon and Nikkor 10.5 lens.

Hope this helps
