It is, but I just feel like half of the L bracket (bottom section) becomes pretty much useless, right? Doesn’t justify the extraneous cost these L brackets go for these days and weight imho. Also, don’t feel confident on holding $$$ gear on 2x2 square instead of the entire horizontal portion of the L bracket. Not to mention, the added weight of L bracket plus the clip bracket and the bulkiness factor.
I’m still curious if somebody else here uses a 3legged thing l bracket for eos r5/6.
