Compared to Fujifilm 14mm f/2.8 (Fujifilm X-E1, Cabin #9 Interior)

Shot on the 16-megapixel Fujifilm X-E1.

Critical note: the Fujifilm X-E1 exhibits a focus creep bug*.

For this example, this damages the sharpness of the Zeiss Touit 12mm f2.8 at f/4 in the closer-range areas in particular (focus creeps to the rear, depth of field is not quite sufficient to compensate/mitigate). Sharpness is apparently restored but f/5.6 via depth of field, but the results are thus suspect as being less than the full optical performance otherwise offers (particularly at closer range).

* The author’s view is that this bug is so serious that it disqualifies the X-E1 (and its X-Pro1 sibling or any camera with such behavior) from consideration, especially given the attractive alternatives free of this issue.
