I have an A7 diaosi version and a d800. Comparatively speaking, A7+28-70 is much lighter than d800, but A7, the diaosi version of 28-70, is slow in focusing and inaccurate (A7S should be much better). So we can foster strengths and avoid weaknesses, and try not to capture and touch people.

In addition, the resolution of 28-50 focal segments is not high, and the resolution of 70 ends is very high. A7 personally feels that it is not reliable to earn money by working, and he is still a tourist and a man-machine. The performance of Nikon Budweiser is worse than that of d800 (the same parameter screen is completely different, A7 highlights are silly white). Taking pictures on 24-70/4 is actually not much better than that on 28-70, and the edges are better and wider;

In addition, the aperture of 28-70 focal length is small, but the high sensitivity of A7S can make up for the brightness, but focusing in the dark is still very stomachache. Snowflake screen may be a common problem of all micro-singles when focusing in the dark. On the whole, A7S+28-70 is more suitable for wedding follow-up. The shed shooting should use constant light to assist focusing.

However, do newcomers feel unprofessional when they see micro-single shooting? After all, it is still the era of looking at the face and looking at the machine.

The video player thinks it is better to buy an APS-C, which will harm CMOS and minimize the cost. In the end, the effect is not very different. .
