Have to admit I was initially stoked about the idea shaving some size and weight off my Z9 by pickup up a Z8, but after walking a lot of trails yesterday with my Z9, 100-400+1.4xTC attached to a Black Rapid sport strap, I have to say I really didn't notice the weight, but sure appreciated holding the big Z9. And today I was out shooting Eastern Bluebirds video and stills all morning off a tripod. For some unknown reason I kept looking at the battery indicator which hardly budged all morning long. Kinda nice not to have to worry about batteries. Anyway, sooner or later I'll probably end up with a Z8 (maybe pick a used one up in a year or two) but for now I've decided to table that idea and instead put the money I "saved" not buying a Z8 towards a 600TC, which for me is better bang for the buck, I think.
