I've started to lean back in the direction of investing more in my kit. I want more lens variety, and more 120 backs, as well as an off camera flash setup for portraits. This week, my primary goal is a ball head for my manfrotto legs. Honestly, GAS gets in the way of building a more professional rig. While I want to become the master of all things RZ, part of me is like, hey I've never shot square format at all! Thats actually a big deal, I want to try it! That said, the Mamiya 6 would be pretty sweet, I honestly just want it all, I think you know the feeling. I appreciate all the feedback, I think this is a subject that requires philosophic input.
As I type this, my Fuji GW690 negatives are scanning, sorry for the digital mention, but I just gotta say, nothing takes your mind off new gear like getting back some quality shots and appreciating your existing stuff. I still believe the GW690ii is the world's best camera, but as mentioned above, you gotta be conservative with shots and portraits are kinda limited.
