Originally posted by Rondec Sorry, I still don't buy it. Fuji works most of their magic by overstating their iso levels, making Fuji image files seem cleaner at a given iso than competitors. By using the x trans sensor, they make certain that DXO Mark doesn't test their images to clarify the situation.
I can just imagine them looking at a 645z iso 400 file and saying "Can you imagine how our fans are going to flip at this iso 1600 image? Why, it looks as clean as Pentax's iso 400 files."
Beyond which RAW files should not have proprietary processing applied. If Fuji is applying processing that sticks with an image when you open it in Lightroom, then that is bad on their part. You should have a clean, neutral file that you can then process however you want.
the accepted level oso difference has been one stop, and the difference is in the look not just the light capability, but if you haven't tried and compared to what you use it's moot. when i changed i was open thanks to a theft, i tried the k3 the fuji and the OM series out. I seriously considered all three series, only wanted one mount so i chose a brand. it was close between Pentax and Fuji, , Fuji won out because i liked the form factor (which is what kept me using Pentax when i went digital), I didn't consider Canon, I did think about nikon but too big and heavy....
I doubt Fuji cares about DXO at all, they want to provide in part an SOOC experience similar to shooting Fuji films and have done so. Don't get me wrong I love Pentax kit (I shot it on and off for most of 40 years) ,
as for the proprietary look, there is a pull down in the develop menu to apply camera setting(at the bottom just below dehaze) , when you open lightroom what you get is the adobe setting (Adobe Camera Raw), that is a proprietary setting as well. you have the option to leave as shot (like say DNG vs PEF) it's not a permanent setting it is a raw file, it is like all raw files the start point for your edit. I actually think for my experience the Fuji XT1 is what a pentax kx/mx/lx mirrorless would be like to shoot.
what is different about the Xtrans is how it renders versus bayer array (iso difference taken in to account) I think the medium format will be a serious competitor to the 645z, I think the reality is though the other 2 will lose more to fuji than Pentax, because despite some similarities the real target is phase who own more share or hassy who have a competing mirrorless (which i think will be crushed by the Fuji) the pentax is built like a tank and has the big beautiful OVF which many will prefer, and since as you pointed out PP is still being done the files will look great either way
