Ok. I have to eat crow here. Previously, on the new Fuji X Forums I said, and I quote: The new FW 4.0 SUCKS.
Well, I was very, very, very wrong! It is AMAZING.
I just returned from a two day long fun Birthday/Pool Party where I shot over 3,660 images with the X-T1 and ONLY the 18-55 and 55-200. I had it set to the Zone focusing 5 x 3. I would say that easily 90% of my images were clear and sharp. This included dogs swimming and running. Two boys of one year old, and a five year old running around and swimming. I am now convinced this is the BEST THING SINCE SLICED BREAD! Here is just one image in a series of 14 photos. 2 were soft but usable the rest were crystal clear. Take a look at the water droplets. This seems like an easy image for the camera but keep in mind the water jumping in front of the swimming dog, or the boys and the camera still stayed focused on the subject!! BTW: THESE ARE ALL JPEGS, LITERALLY FROM THE CAMERA, INTO LR, TO HERE. ZERO EDITING OR SHARPENING. CLICK TO VIEW IMAGES AT LARGER SIZE.
Here is a series of my car loving 1 year old grandson riding his little cart down hill. EVERY SHOT IS IN FOCUS. These are all 55-200 between 55mm and 75mm, JPEG, ASTIA, straight out of the camera into LR, then here. Zero sharpening or any adjustments. Unreal!
