As a quasi-professional "travel machine", the purpose of using a wide-angle lens is to cover more pictures. In the past, wide-angle zoom cameras were all very large in size, and Samsung has begun to reduce the size of such cameras, which is only 99.5 x 59 x 21.7mm, already reaching the size of a card camera. At the 798 outdoor scene in Beijing, I first tried to shoot with the 24mm wide-angle end of the Samsung WB700, and completed a set of photos with a reflector.
