I just got hold of Fuji’s MCEX-11 (11mm) and MCEX-16 (16mm) Macro Extension Tubes and I wanted to do a quick comparison. Fuji has a table on line with all the information in numbers form about focus distance etc, but photographers are visual beasts. So as I couldn’t find much in picture form on line, I thought I would show some examples of what you get from each of them. I have included one with just the lens, one with the 11mm, one with the 16mm and one with both tubes stacked together. All shots were taken with the camera as close to the subject as possible. I basically focused each lens to minimum distance and then moved the camera in until it achieved focus. I have kept the subject the same throughout (my X100S) so that you can get a good idea of what the difference is from lens to lens with each tube. All of these JPGS were shot square in camera (yes, your X camera shoots in square and 16:9 too:o). Please note, the wider lenses (14mm, 18mm & 23mm) worked with the MCEX-11, but the lens touched the X100 before focusing was achieved with the 16mm or both stacked. The 35mm lens went in so close with both tubes attached, that I had to remove the X100S lens hood…….
