The lens is needed by all those who travel and do not want to carry a suitcase with equipment or as a staff member for an advanced amateur or even a professional. My friend many times urged me to take only with a fixed focus - they are better in sharpness, this is indisputable, but I personally am not ready to take and drown several lenses in the river on a trip with a cost of fifty kopecks each. and fixes are for the studio, I personally do not care (at least now).
