Thanks again, guys.
H - you're too kind!
I wish I showed up this good looking in portraits! haha.
Meant to mention, I had left my 100-400L back in Brisbane. Normally that's what I'd use here. But the 135L did a wonderful job, and much more compact.
Re: the comments on sharpness - feel like I'd be doing the 135L, one of Canon's finest, an injustice if it wasn't sharp and in-focus.
