Recommend a few low end SLRs, and recommend mid range SLR cameras。。。。。。

Pentax KX uses No. 5 battery, if you choose Sanyo Eneloop, the performance is almost the same as that of lithium battery, and the battery life is much stronger than that of ordinary entry-level machines (about 1000 shots on a single charge).

The Sony A290 uses CCD as the image sensor, and the high sensitivity is poor, but the image quality is good at low sensitivity.

The Nikon D3000 also uses CCDs and has the same problem.

The KX uses a 1200W pixel CMOS, and the high sensitivity is much stronger than the other two, but the low sensitivity image quality is slightly worse.

KX is recommended among the three,Xiaoqiang in the entry machine,At present, parallel goods are very cost-effective,A290Compared with much cheaper,Slightly less functional,And ugly,D3000The same,The function is not as good as KX

To say that the most value-for-money entry machine is definitely Canon's EOS 550D, except for high-speed continuous shooting and focusing speed is not as good as 7D, the other configurations are basically the same. And it has a large 104W pixel LCD screen, which is the best display in its configuration.

You can come to the Jumei.com photography forum to have a look, there are professional customer service and teachers to give you better answers.

D3100, the most cost-effective machine this year, has been upgraded a lot compared to 3000, but it is very low. Compared with 3100, the two models of the S and K families can be killed, of course, if you compare with 3000, KX can also be compared. 3100Compared to KX,When you buy it, you have the conditions to compare,Workmanship,The difference in control and picture quality。。。

The body has basically nothing to do with image quality, but the D90 is too old.

Alas, a little better picture quality? It's hard to say,Machines of the same era,The image quality can be considered the same,In fact, the image quality is very related to the lens,D90Don't think about it,If you want to go to D90,It's better to go to D3200、D5200, etc.,Because D90 is mainly able to support old lenses,Others are not advantageous。

If it's just D90 and 60D, it's still 60D, after all, D90 is too old.

After 70d comes out, 60d is so cheap, the budget is not enough to buy a second-hand one, second-hand 50d is also a good choice, I personally love and canon.

Canon: 600D 550D with 18-135mm

Portrait effect is good! More than 5000.

Sony SLR is good, and it can be turned to the frame.

The best value for money is the 550D.

The best buy is the D90

ps: The most cost-effective SLR is often the most in the second-hand market, because when you buy it, you are pursuing cost performance. I had to sell it for a replacement. Buying and selling is actually more expensive.

PS again: D90 has been discontinued, and now it is sold in stock, and the price is in the end, so buy it with confidence and don't regret it.
