When I first used the 645Z to do a youtube review from my friend in the summer of 2017, I was blown away, I didn't care about the the size of the camera anymore, mirrorless? what is that?! lol , I was so blown away by the raw files, and the image quality, been thinking about it ever since. So... I finally jumped and purchased the 645Z from my close friend who was selling it last month Feb 2019. He sold his 645Z and M-P 240 to get a Fujifilm GFX 50r, I'm gonna do some comparisons soon in a couple of weeks, but I actually prefer the colors from the 645Z and grain better than the GFX, though the same sensor, I think the 645Z has more DR
