You're an idiot.
OP ignore this, the IO has exactly the same lens changing process as the I/OX except for the fact that the IOX's are attached to the riggers, so you have to twist them about to release the lens.
The I/O has 2 clips on top of the frame keeping the lens in, and once you've unclipped them it just pulls out.
The I/OX has the 2 clips on top of the frame and also the 2 outriggers are stuck on, so you have to twist them about, believe me this is fucking annoying, if it wasn't for this I'd have a pair.
OP - My review if you're interested:
Also OP if you know the I/O's fit, get them, they're better than the I/OX's in lots of ways.
