To make an informed decision, it's crucial to research the specific DR settings of these newer models. I recommend visiting the official Fujifilm website for technical specifications and exploring camera reviews on reputable photography websites like DPReview or Photography Life. DPReview's forum could provide insights from experienced users who may have firsthand knowledge of the ISO settings associated with DR400% on different Fujifilm cameras. This thorough research should help you determine which model aligns best with your photographic preferences and requirements.
