High score bounty a few questions about the Sony A728.

Hello, I used the A728 originally, and now I use the XK, let me help you

1,I didn't install that disk,Because I'm nwz-a728,I directly transfer files,Song information,**Cover or something is good with other software,For example, Qianqian Jingting,iTunes,***JAGTOOL, etc.,It's very convenient。

2,ATRAC file is a format developed by Sony itself that is better than ***,Using Sony's own lossless compression technology,The highest bit rate is 352kbps,The sound is slightly better than the *** format,And Sony's machine**ATRAC format file is more power-saving than the ***** format。

4, I'm not impressed by this, I'm sorry.

5,This machine is divided into NWZ A728 and NW A728 two kinds,The Japanese version is NW A728,To use software transmission,Can't drag directly,Most of the other versions are NWZ,All files in NWZ can be dragged directly,But MP4 format files have higher format requirements,Such as frame number,Resolution, etc.,Many conversion software converts MP4 format A728 does not support,This is more troublesome。 You can check the specific parameters of a728 on the Internet, and write it in great detail, or ** there are also detailed parameters.

6, Sony has launched *** in recent years, long press is standby, convenient and quick start, and automatically shut down after 24 hours. Arbitrary key to start

7, I don't know about this, I'm sorry.

8. Yes, you can make the ID3 file of each song when the song information is in the song, including the name, **, singer, style, year, etc. A728 can also be classified according to these items.

9,The function of this machine is relatively simple,It is,****,**browsing,And the format of ** is less compatible,**Browsing can not be enlarged or reduced,In short, it is a pure **** device。 This machine doesn't have a recording function, and there is no radio. In fact, the functions of many big-name first-class devices are very single, but the quality can be trusted, but the functions of domestic cottages are varied.

That's all I know and I hope it helps.

You can give the manufacturer a ** buddy!

You have to understand two things.

First, there is no direct relationship between the focal length and the content of the shot, you can shoot portraits with 28mm, and you can shoot landscapes with 200mm, so there is no absolute standard to follow, it all depends on your technique.

Second, as far as the camera lens is concerned, the 35-85 focal length is the most ideal focal length and the cheapest, because the distortion chromatic aberration is very easy to control, and the technology is also mature. In terms of type,Macro image quality is the best,Fixed focus and large aperture second,Zoom is much weaker,Large zoom is basically impossible to see。。。 The water army does not blow 24 240 who will buy this head.

Therefore, if image quality is required, then choose 1-2 fixed foci, such as 35mm with 85mm, the former to shoot the scene, and the latter to shoot people.

If you want to save time, 2470 is the best choice. Standard focal lengths are covered. The picture quality is also good. 28 70 can also be selected (cheap), but the quality is definitely more than a notch worse.

If you want to take a single shot, you have to accept the degradation of imaging quality.

Sony's second-generation full-frame mirrorless A7II, the biggest highlight of the machine is the addition of a five-axis anti-shake system on the fuselage.

The official announcement of the A7II's anti-shake system supports the ** compensation of the appointment, and the appearance of the fuselage and the key positions have also been newly designed, and the boot speed and focus speed have been increased by 40% and 30% respectively.

This machine is both offensive and defensive, on the one hand, it repairs many problems left over from the A7 body, such as slow focusing, poor hand feel, etc., and on the other hand, it adds a new selling point - five-axis image stabilization. Although it sacrifices a certain amount of body thickness, it is a very good deal to think about, because all the lenses used on the A7II have good image stabilization. Compared with other full-frame SLRs, the A7II not only has a smaller size, but also has a WiFi NFC function"Full DSLR image quality + mirrorless high portability"The best of both worlds, only the A7II can do at the moment.
