What kind of SLR should beginners buy, some parameters of SLR, and some websites to learn photography.

You can buy a SLR according to your own economic strength, usually an entry-level kit. You can also add a standard fixed-focus lens (50mm f 1.8). It depends. We'll add the lens later.

There is also a rich introduction, that is, tens of thousands of professional SLR plus constant large aperture zoom lens.

Canon and Nikon brand photographic equipment are recommended mainly because of the huge lens group and mature technology.

At present, the main indicators to measure a digital SLR are: the size of the photosensitive element (whether it is Quan Huafu), the highest pixel, the highest shutter, the shutter lag, the highest continuous shooting speed, the highest sensitivity ISO, the focus of the focusing system, whether the LCD screen has a shoulder screen, the body material and so on.

The main indicators to measure a lens are focal length, maximum aperture, lens material (whether it is a low dispersion lens or even a fluorite lens), anti-shake function, coating grade, lens design (such as internal focus, waterproof and dustproof) and so on.

The main websites that you can learn are Color Shadow Unlimited and Hummingbird.
