Q: 6. Hi all, and especially any Sony FS7 users: With the clamp-on option, would this be acceptable to clamp onto the bundled FS7 zoom lens, or too heavy for the lens mount or in the way of the viewfinder? Thanks!

A: I think it might be too heavy especially with two filters, I have a FS7 and I use this with the Zacuto VCT Universal base plate that has rails. I found the shoulder rest on the FS7 was not that great, also the baseplate works with my old sony quick release plate. Mounting the matte box to the rails is quick and easy.

Q: 8. It works with a DSLR Nikon D7200 camera?

A: Yes it can with the proper ring, but would be overkill. I returned it for the sheer size of it, its huge! Looks to be made more for the huge Cine lenses canon and others make. Id get one geared more to SLRs unless you have the big Cine lenses.

Q: 9. No flags on the top ?

A: Hi Michael - the standard bundle does not include flags. Check out the Deluxe Bundle which includes top flag and sidewings, and is usually a great deal

Q: 10. The Deluxe bundle was supposed to come with the universal donut, yet mine did not. Anyone else get the donut package instead of the universal donut as advertised?

A: Mine came with the foam donut set, as well as a universal donut which looks more like a hood. It's a soft fabric with a draw string on one end. Perhaps it's there and you just expected it to look like something different?
