Will the double handles come with the packaging? Can the double handle be detached?
Yes, the dual handle and video rig are packaged together. You can install it freely, and handles can be installed on all four sides of the rig. It has multiple 1/4" screw holes.
How does this device "stabilize" the phone？
It doesn’t have a stabilizer but the wider grip allows for more stable footage than strictly handheld. I use this with an iPhone 12 Pro Max and it provides stable handheld footage.
Will an iphone 13 pro max with an otterbox defender case fit this bad boy?
I have a 13 pro max… it only fits without the case. I love this device. And if you’re careful, you will be fine while you’re filming.
Is there enough clearance to mount Sandmarc/moment lenses if you have one if their cases?
It depends on the size of the lens, we don't recommend using the lens on the phone. The lino video rig has a compact design and is suitable for use with extended lights or tripod accessories.
