I, too, have been the unfortunate recepient of a defective X100F. Had it for a week before I realized that my aperture blades had become stuck in a fixed position somewhere in the middle of the scale. Googled the issue and was quickly able to diagnose why my outdoor photos were getting totally overexposed. Called Fujifilm USA to see if they had a solution but the only recommended remedy was to return it to Adorama from where I had just purchased it. Frankly, I'm not too thrilled with the situation but I am getting a new one in exchange. I'm hopeful that the replacement will be fine. I've already sold all of my Nikon SLR gear with multiple lenses and I have high hopes that the X100F will be a wonderful tool that will produce fabulous images.
