Just pat the scenery when traveling. Select Sony Black Card m 1 or m3. Is it necessary to buy m3? After all, it is quite expensive.

Compared with M 1, Sony RX 100 black card camera M3 has the following advantages: 1, back-illuminated CMOS, and high-sensitivity image quality is better. 2. Pop-up single-barrel viewfinder is adopted, which makes it more convenient to take photos under strong light. 3. Have the ability to shoot high-bit-rate (50) short films with better quality. 4, there is a flip LCD screen, which is more convenient for framing. 5. The wide-angle end of the lens is extended to equivalent 24mm, but the telephoto end is only 70mm (the former is 28- 100mm), and the aperture is increased to F/ 1.8-2.8 (the former is F/ 1.8-4.9). It can be said that a penny is worth a penny. M4 began to support true 4K video shooting. Actually, it's of little use.
