The DOF for this new beauty is essentially equivalent to the X100VI F2.0 Lens on the APS-C sensor. So, while the F4 sounds less appealing, up against a much larger sensor it is capable of very solid shallow DOF photos. I am very eager to get my hands on one and look forward to adding this camera to my collection. I think it's difficult for some to understand the huge accomplishment Fujifilm has made with this amazingly small, compact, lightweight medium format camera! This is a big accomplishment; they have literally brought a whole new level of photographic quality to the masses.
