but it's the 3/8" hole that i am curious about, what's that for?
That's an accessory socket

A quick comment on this "L-Plate Set"; I've been a user of both RRS and Markins, while Markins is usually more competitively priced, RRS does have a quality edge. Does that justify the substantially higher cost for RRS? I don't think so.
However, there are a few features not found on the Markins L plate - first the "tool-less" screw (I hate carrying allen keys) since I frequently remove it. Second, holding the A7(r) with the bracket mounted makes it more comfortable to hold, i.e. my little finger no longer curls below the battery chamber. The latter applies equally to the bracket with or without the "L-Plate". It's quite possible the same applies to Markins'.
Regarding the cable clamp, an item most likely of interest to those who want to use the A7(r) for video work, its RRS part number is CA-1.
