Extended data:

Different shooting occasions, suitable for different lenses:

1. Mainly focus on wide-angle landscape photography.

The scenery is dominated by large scenes, so a wide-angle lens is generally used. Because Canon uses an APS-sized CMOS photosensitive device, the film corresponding to the original lens has a magnification relationship of 1: 1.6, so the focal length of the original lens is 28mm times 1.6, which will become 44.8mm, so there is almost no wide angle.

2. Mainly based on tourism photography.

Traveling abroad, a simple, portable, light-weight and high-quality lens should be the focus of consideration. If you choose the lens with the concept of "a mirror travels all over the world", even in places with insufficient light such as museums or stalactite caves, the lens with anti-shake function can well meet the shooting requirements.

3. Portrait photography is the mainstay

Portrait shooting is generally the only way for photographers. Generally, the focal length of portrait lens is in the range of 50~ 135mm. Typical lenses are EF 85mm F 1.2UL and Ef85mm F 1.8U, and the prices are 13500 yuan and 2850 yuan respectively. However, due to the limited economy, it is still an extravagant hope to spend less money to equip fans with a special portrait lens. Therefore, some fans turned their attention to the medium telephoto zoom lens.

4. Macro photography

Nowadays, many photographers like to take macro shots and record the flowers and cordyceps in their memories. The common method is to use some zoom lenses with macro mode to shoot, but because of the proportional relationship of zoom lenses, macro shooting can not be fully played, so special macro lenses are generally used to shoot.
