For this photo I used the tiny (1/4 palm size) Joby folding tripod. The wide (17 mm equiv. FL) lens is very handy in indoor shots like this. I tried touch-focus to get the main focus on the rear wall, but that failed. The menu board at upper left is sharp, but the blue board slightly lower and to the right is a little blurry, and that's not the fault of the lens. Cropping was less than 5 percent of the width, but quite a bit of the height to get rid of some of the floor and ceiling. iPhone 6s-plus, Zeiss ExoLens, Cortex Camera App, daylight through window.
