Which is better, Sony a7 or nex7?

On the whole, a7 is better. After all, Quan Huafu still has some advantages in image quality, especially in high quality. However, if you add convenience and cost performance, it's hard to say. Let me briefly talk about the advantages and disadvantages of a7, and elaborate on the advantages of nex-7 (not to mention the disadvantages of nex7, the advantages of a7 are the disadvantages of nex7).

Advantages of a7:

The main advantage of a7 is image quality. The frame size of Quan Huafu's 2400w pixel sensor is 2.25 times larger than that of nex-7' s C-frame 2400w pixel sensor. The actual picture quality performance is that the low-sense color and layering are slightly better, while the high-sense purity is about two grades. Moreover, the general trend now is the gradual popularization of Quan Huafu. It doesn't matter at home. Want to learn photography, want to further study, buy a full-frame camera directly.

Disadvantages of a7:

Quan Huafu has fewer lenses, so it can't give full play to the advantages of sensor size when using the half-width head (after cutting, the performance is not as good as nex-7 using the half-width head because there are only10 million pixels left). And the volume is slightly larger (the fuselage and the same level of the same lens are larger than nex7). Moreover, since Sony does not have a full E-word, it is estimated that in a few years, many focal segments will be realized by bayonet lenses such as A-port adapter rings.

Advantages of nex-7:

And nex7 also has its advantages. First of all, it is much smaller and weighs one third. With the first half of the lens, portability is more advantageous. Secondly, the 2400w pixel cmos of nex-7 is enough for daily use, and the low sensitivity is also good, but the high sensitivity is poor. If there is little demand for high-sensitivity shooting, nex-7 is also a very sufficient model. And the price has bottomed out, and the overall cost performance is higher. (Especially for home users, the balance between small size and excellent image quality is obviously better than that of full-frame cameras. In addition, Sony E-mount lenses are more, and there is a lot of room for lens selection. Zeiss 18-70 is the on-hook camera that pursues image quality, and 18-200 is the one that travels around the world. There are many other fixed-focus zoom lenses with different positioning. These are for the time being.

In addition, the battery life of nex-7 is longer than a7, and continuous shooting is faster than a7. Of course, this is not very important.

Summary: a7+28-70, the overall price of this camera is very cost-effective. With one or two fixed focus, a good system can be formed, and the picture quality is excellent. It can be said that it is one of the most cost-effective full-frame cameras at present. If you have a sufficient budget and are interested in photography, it is highly recommended to go to the whole picture. . . The nex-7 has more adaptive body and lens combinations. If only one machine is selected, it has a great cost-effective advantage. If it's just for home use, then nex-7 is enough. For tourism, the portable combination of nex-7+ 18-200 is a mirror of the world, which a7 in Quan Huafu can't catch up with.
