Per Fuji the lens can detect when it’s on a tripod and will turn off OIS. I haven’t used this on a tripod yet. But then again I usually forget to turn OIS off when using a tripod anyway... I used the lens last weekend and loved having those extra stops. It doesn’t have the same punch as the 18-55 - I felt that the photos needed more sharpening and contrast in post than I normally would do but that could be a result of the lighting and subject. I was outdoors on a foggy and gray day photographing trees and snow. Not the best conditions. I plan to take both lenses out with me next time the weather is better so I can do some real world comparisons.
