This AstrHori 18mm 8.0 Shift is already the third AstrHori lens I am reviewing here. Their lenses often feature a “little extra” over the competition to make them more interesting. In this case this isn’t just a compact 18mm lens, a ±6mm shift function has been added on top. Judging by the size of this lens, especially the diameter of the lens elements, I am wondering how useful that shift function will be though. But let’s have a look together in this review.
