I want to buy an entry-level SLR digital camera, please ask someone for help.

At present, the Canon 400D kit is about 4600, and now the 400D fuselage has fallen below 4000. The price of the newly released 450D may be a little higher, and the pixel of the 450D is not much higher than that of the 400D. The LCD is also larger than that of the 400D, and the popular live view function is added. These just make it easier for you to take pictures, and they are not necessarily related to the imaging quality. Pixel height just means that you can output a lot of photos. We seldom output big photos at home every day. The lens used in the 400D set is 18-55mm, but this lens has no anti-shake and ultrasonic motor, which means that the advantages of Canon lens are the same. Ultrasonic motor makes focusing faster and more accurate, with low noise. Incidentally, all the 400D lenses sold in Japan are equipped with ultrasonic motors, while the 18-55 lenses sold in Chinese mainland use arc motors. 400D has also introduced a set of Canon 40D machine with insert core (17-85mm), and the price is around 6900. We recommend this machine. The focal length of 17-85 can basically meet the needs of beginners, and it has anti-shake and ultrasonic motor. After upgrading, it can be directly connected to a Canon lens with a focal length of 70-200. Canon and Nikon have a wide range of lens choices. The disadvantage of the 400D is that the fuselage feels bad, the fuselage is too small, and it feels uncomfortable to hold. The shape of 450D fuselage is similar to that of 400D, and the endurance of 400D is not strong. These two shortcomings can be made up by adding a battery handle.

Pentax works well, the fuselage is cheap, and it is compatible with the previous manual lens. However, Pentax's lens group is still relatively small, and the after-sales service is not as convenient as Canon Nikon.

Now Sony's A200 dual headphones are cost-effective, but the main advantage is the advantage of the set. Sony still has too few lenses, which is not conducive to future upgrades. If you don't consider the future upgrade, you should choose the focal length of A200 two lenses for daily use.

Nikon D40X is an entry-level SLR with a relatively high neutral price, and it also has a good performance in imaging, but D40X can't support AF head, which makes its subsequent upgrade very difficult. Nikon D80 set is about 7900, D80 set is 18- 135mm, focal length 18- 135 is dominant, and there are many other disadvantages! Plastic bayonets wear well! Followed by the resin lens, although the weight is light, but the photo effect can only be said to be average! Just like the performance of the machine itself, I suggest you buy a D80 fuselage and match it with a lens according to your economic situation.
