I just posted on a FB page but I'll also post it here:
Hey Fuji X-t2 users...........anyone notice the almost rattlesnake auto focus motor response with the new X-T2 Camera Body Firmware Update Ver.2.12
I immediately noticed this characteristic with my 56mm and 16mm prime.
I'm assuming this is the new firmware attempting to speed up the autofocus acquisition.
Not a big deal but for some but what will be noticeable is that in constant AF in video mode non external mic use will have alot of noise picked up.
If you compare this AF motor algorithm vs a Canon with dual pixel technology it's like a comparing an erratic unrefined unbalanced engine to a purring V12 power plant (silly analogy). I sure hope Fuji refines this firmware with smoother AF.
You can observe this new "change" by the erratic vibration of the camera body.
I'm not quite sure if the AF is really that much faster but now. I'm finding that my X-t2 seems more of an unrefined juvenile system rather than the mature system that it is......
Not really nit picking since I still mainly use my fuji for stills. This is just my observation.......
