A:AnswerThis tripod should work okay for a 35mm web cam depending on how much panning of the camera you are doing and how heavy the camera is. It does fine with a smart phone and small hand held video camcorder.
A:AnswerYes, I acquired both the Canon 90D and the tripod at the same time since I had experience with both on my job with company-owned equipment. They work well together.
A:AnswerAssuming your projector is the LG PH550, I would say yes it will hold the projector...weight wise. However, does this projector have a mounting port on the bottom to mate to the mounting of the tripod? If so, it should mount easily. However, the projector will have a larger footprint than a video/camera and this may change the center of gravity of the tripod. Spreading the legs to the maximum would aid in a possible reduction of this change.
Should you attempt to make this attachment, try it on a level surface and check for any unbalance issues, run the cables down the center of the stand to aid in a reduction in the center of gravity change.
If the projector does not have the correct mating/attachment locations, a suggestion would be to locate a more suitable mounting surface.
Just my $.02 worth.
A:AnswerI have an iPhone X and it fits fine. The iPhone 11 is just under 5 mm wider than the iPhone X but the cell phone adapter provided inside the box seemed like it had more room to expand to the desired width.
A:AnswerI am pretty sure it will work well. The screw turns to meet the depth so it will fit a bunch of cameras. Your camera is lightweight so you should not have the braking issue I did with my zoom lens DSLR. The legs fold up faster then my ~$600 set up. Good luck and have fun!
