Why did you leave the system and come to m43? The two biggest complaints I've heard have been AF speed/acuracy, and post processing of the RAW files. From what I've heard, the new firmware for the XT1 eliminates the AF speed/accuracy issue, and supposedly LR6 made some updates to its processing engine that improves the way it handles x-trans raw files. I handled an XT1 a month or so ago, and didn't find the ergonomics too bad (I didn't think they were as good as my GH4), but the EVF on the XTI. Oh. My. God. I thought the EVF in my GH4 was great, but the one on the XT1 is HUGE! The lenses for the system are also amazing. The primes are very sharp and fast, and the zooms are nice and sharp, while being moderately fast (the 18-55 & 55-200). My interest in the system is because of some of the lenses offered (fast f/1.4 primes), and the ability to generate slightly shallower DoF without giving up too much in terms of size/weight (yes, the lenses are slightly bigger than m43 equivalents, but much smaller than lenses for a system like the Sony FE). My primary concerns about the system are AF speed and accuracy (the GH4 is excellent in this regard), as well as processing the raw files (I already have LR, and really don't want to shell out $300 for a different software like C1P). I don't want to start a m43 vs Fuji battle here, I simply want to hear from people who have used both systems as to why they still shoot m43 vs. Fuji, and what they liked about the Fuji system vs m43 (and vice versa). Thanks!
