Long time MF user here - one of the first to get IQ100 in USA, (and IQ180, P65+, P45+ before that). Also own Alpa's (various) Sony, Canon and Leica cameras, and Phase XF, DF, etc. The point is: there has literally been no 'must have' piece of gear for me this year. I'm amazed, and my wallet is happy, but I'm wondering what happened, and is it only me?
I'm at 28,000+ (non commercial) exposures for my IQ100, and extremely happy with it. The new Fuji GFX and Hassy MF cameras look promising, but once you're on 100Mp it's very hard to step down to 50Mp and still be in MF. When new versions at 80+ Mp come, I'll possibly buy in, but not yet. If I need light body with good AF and fast quiet operation, I'll take the A7R2. But once you've gotten used to a 100mp output from IQ100 on Capture One's profiles, anything else is *so* poor in comparison, it's tough to swallow.
Quite honestly the best 'gear' I got in the last year was free firmware 'Feature Set' from Phase - the Focus Stack and Electronic Shutter options. Great improvements to existing equipment, and you can't beat the price!
When/if Phase bring out a new Mirrorless body, or a GFX2 comes out, I'll probably jump, assuming it's at least 80mp, otherwise, I'm just content with things.
