the screw on my current plate won't fit into my dslr (Canon 70d). Will this work?
I have a 7D, 5D and 6D and it fits to all, same with my iPohe and iPad holder.
As far as I know,there are two standardized thread sizes used for camera mounts: ¼”-20 tpi (threads-per-inch) or 3/8” screw sizes. With the exception of heavier pro cameras and tripod collars on heavier lenses, which rely on 3/8” screw mounts, most consumer cameras use ¼”-20 screw threads. , There are cheap adapter screws/nuts available to change this o change from small to large, but to be honest, I have never had any problem. You should be able to change a 3/8 screw in the plate anyway to a 1/34 and vice versa
