I am very tired of Fuji as a whole... They automatically deny responsibility on issues, quote crazy high repair prices and timeframes and when I accepted a (refurbished" replacement 100-400 instead of a repair because to would be cheaper and faster it developed the exact problem a couple years later, My XT4 is absolutely unreliable because of the turn on turn off issue that has persisted through numerous attempts to fix it and my 10 to 24 would not focus at infinity and struggled to focus at all, and I went through two of them because of focus issues. My sigma is much better.
