Interesting video. I have the TTartisan 90mm and a 18mm extension tube which I was hoping to use for close-up portraits. But the maximum focus distance is something like 40cm, so the lens is too close to the subject's face. What is the focus range on the 90mm with the 11mm extension tube? I can't find that information anywhere online

in my experience the TT 90 gets just about the entire head plus maybe an inch on top and bottom (below chin) the 11mm makes the face format filling, working distance is ok, far enough for people not to feel like you will hit them in the nose and for the lens not to create problem with lights (shadows,...) about 50cm. its still close of course and depth of field is very shallow. I am surprised how well the lens performs stopped down, diffraction definitely starts to creep in but it's not bad. I guess all these lenses act differently with different tubes, I just find the gf glass more or less useless with any and all tubes (the shorter the tube, the more likely you might get a useable result but still) the obvious disappointment to me is the GF 120 macro which is a great portrait lens IMO (for those close up portraits you are looking for) but difficult of actual macro application: strong field curvature and completely useless with all (including fuji!) tubes.

@@paulschefz thanks for your reply! So let me understand correctly, with the 11mm tube, the minimum focusing distance on the 90mm TTartisan would be about 50cm? I have the 18mm extension tube already, but the problem with that is that the _maximum_ (not minimum) focus distance is about 40cm, so it is simply too close for any portraiture. Do you have a clue what the maximum focus distance with the 11mm tube on the 90mm TTartisan would be?

@@thomasstarlit2427 to be honest for that kind of close/tight portrait the fuji GF 120 macro is a phenomenal lens, it draws really well, gets close in at good working distance and has good AF. terrible macro lens, great portrait lens. of course big, heavy and not cheap.
