I think many photographers may be willing to be adopted for a few of those gifts ;-).
Thanks Rick. I was wondering what you thought of your new gear. Didn't know you had picked up the RF 600 f/4.
One small tweak I may make to my kit as it looks like I am staying EF for the foreseeable future would be to start using the drop in filter adapter and not have to pack multiple sizes of different filters (I typically travel with 6 different front end filters). They wouldn't be stackable, but I do not often do that anyway.
