Hi, I used to be a pro photographer for 10 years (wedding and commercial) but have since sold all my Canon gear and now shoot Ricoh and Leica.
I currently own a GR3, GR3X and the new GRIV. I'm enjoying the GRIV as my GR3 got the scroll wheel issue, although I just tried it and the scroll wheel is working again... Anyway, the GRIV is great but I haven't taken it out for a proper testing but so far the snappy focusing and battery life are both a very welcome improvement over the GR3.
