Hi Martin, it could be possible that MoI and Keyshot measure the field of view slightly differently.
MoI measures it such that field of view covers the innermost square of the viewport, meaning the lesser of either the width or height of the image. This is so if you change the viewport size to different aspect ratios the field of view kind of adapts to the size.
Many rendering programs measure it strictly by image width. So you may need to incorporate a modifying factor of your image width/height aspect ratio into there to get it to match.
