What camera is the best to buy when traveling? SLR? Micro single? Telephoto?

If you want to take pictures of landscapes, a large-soled portable camera is recommended.

1. The SLR is stupid, big and dark. Although the picture quality is good, it is a burden when traveling and is not recommended;

2. The mirrorless camera has good picture quality and is characterized by interchangeable lenses. If you don’t plan to change lenses, using a mirrorless camera will lose the advantage of interchangeable lenses. Since you don’t need to change the lens, the outsole card is more portable, and the image quality is no worse than a mirrorless camera;

3. For outsole portable cameras, we recommend Canon G1X or G1X second generation or Sony RX100. RX100 is even more recommended. There is no better balance between quality and portability;

4. Telephoto cameras are not recommended as the picture quality is too poor to watch.

Hope this is helpful to the original poster.
