Can you mount any camera to this? i don't know a lot about photography. looking to use this for a sony ev-10.
You can definitely use this ball head and mount for the Sony ev-10; I use this Ulanzi quick release with several different cameras [sony and canon], including the zv-10.
What is the exact screw size? A 1/4 inch what? 1/4-20? How many threads per inch? I need this screw to thread into a blind nut so need the size thread
The thread size is 1/4-20, which means 20 threads per inch. Home Depot would have plenty of those nuts!
Will this fit on a 3/8 screw? i have an adjustable arm i wanted to use to mount this so i could connect with other clamps.
Yes.
