I want to buy a Sony SLR A series. Is the a330 or a390 or a550 more cost-effective? I like a clearer screen. High color. Ask a master for help.

Like you, I'm going to buy Sony machines in the near future. .

One: According to your requirements, a550 is better in screen, and its screen display effect is good enough to deceive you. The screen of a390 is obviously not comparable, but it is enough.

Two: If you want to say the difference between the three machines, you can say a lot in detail. I will briefly talk about a few aspects. The continuous shooting function and battery life of the 390 can only shoot 500,550,450, and you can shoot 1000 at a time. HDR (see Wuji for details) is very useful for taking pictures of scenery, but the 390 doesn't have this function. There is also a high sense, 390 high sense is a grade.

Third: I think after all, we all buy thousands of cameras, and finally go to the photography forum to see the effect of photos taken by others. The most important thing about SLR is image quality. In fact, these machines you mentioned are all very good after use.

Fourth: if you pay special attention to the screen effect, it is best to use 550 for his screen, of which 450 is the lowest end. 450 and 550 are a series, and their main difference is that the difference between screen and lv function is 8900.

Fifth: If you are not short of money and want to look "beautiful", use 550. Her rotating screen can charm some ignorant little girls o∩_∩o, but if you don't have much money, use a390.

Sixth: the price of 550 is around 4,200, around 450,3699 and around 390,3699.

Seventh: Regarding the inspection, please choose a more formal store to buy, recommend Yi Rui (online shopping), and it is best to go to a physical store to buy. At the same time, remind not to buy it in Zhongguancun. Invoicing requires machine typing, and handwriting is invalid.

When you buy it, cover it with a lens cover and take a black photo to see if there are any bad spots. More than three bad points can be dropped. Sony's packaging is sealed, so check whether it has been opened when you buy it.

To sum up, I recommend you to use 550, the price is worthy of its performance. Also, learning photography is a time-consuming thing. It has many functions, so that you can have better results. Don't worry too much. You won't need it.

In addition, there is an old hand in taking pictures. He usually takes pictures with automatic gear and also uses a SLR camera. It's not that he can't do it manually, but he can focus more on composition and conception. He also said: A good camera has a better automatic transmission. You can visit his blog (Spring Roll Blog). I didn't make it up myself.
