What does the wide angle of the camera mean? How big is the wide angle?

Wide-angle lens: also known as short-focus lens, simply speaking, standing in the same position can shoot a larger area with a wide angle. Wide-angle lens, because the lens is very short, the scene on the projection film is smaller, so you can shoot more scenes and more wide-angle images in a narrow environment;

The term wide angle is a very important lens concept for photographers. The so-called wide-angle lens is a lens with short focal length and large viewing angle. Take the common 135 camera as an example. Common wide-angle lenses are 15-30, 16-35, 17-35, 18-28, 18-35, 20-35 and 20-35.

The purpose of using a wide-angle lens is to obtain a wider field of vision and magnificent artistic effects. Wide-angle lens can produce the effect of big prospect and small prospect. The distortion of the picture produced by wide-angle lens exaggerates the foreground object, highlights the foreground object more, and gives people a strong visual impact.

Generally, wide-angle lenses are mainly used to shoot magnificent buildings and large-area landscapes. Using its characteristics, we can show a unique momentum and show the shocking power of the picture. Wide-angle lens can also have special effects in portrait shooting. Compared with plain portrait shooting, wide-angle shooting is used to dilute the background and make the subject of the character more prominent. Now many photo studios adopt wide-angle portrait shooting technology.

For consumer digital cameras, the so-called wide angle is actually 28 mm, Olympus 5060, Nikon Coolpix 5400, Minolta DiMAGEA 1 and Sony F828. These high-end wide-angle digital cameras all have different grades of wide-angle lenses, and the prices vary greatly. Moreover, A 1 5400 and F828 have not been listed for a long time, and the overall quality has not passed the test of time.

Generally speaking, due to the difference between digital cameras and traditional cameras, digital cameras need to have greater requirements on lens performance and manufacturing technology if they want to achieve a wide angle of 28 mm. Therefore, the general 28mm wide-angle lens digital camera can only be found on high-end or expensive digital cameras. Based on the high price of wide-angle digital cameras, ordinary digital photographers may not be able to enjoy wide-angle shooting.

However, the author recently noticed that Ricoh's Caplio RX is an entry-level digital camera with excellent functions and affordable price. Caplio RX changed Ricoh's previous style with only connotation but no appearance, and made great progress in appearance. The slim body of 29mm aluminum alloy is the first digital camera of its class with 3.6 times optical wide-angle zoom lens of 28- 100 mm, and it is also the fastest in the world. Plus excellent macro 1cm. The volume is only11.6x29× 56mm, and the weight is 165g. Since Ricoh launched the 28mm wide-angle digital camera Caplio G4w last year, I believe the production technology of wide-angle lens will be more mature than other brands. The appearance of Caplio RX promoted the popularization of wide-angle DC.

As an indispensable indicator of photography, wide angle is an indispensable shooting element for every photographer. Reasonable choice is extremely important for daily shooting and creation.

At the same time, every consumer's needs are different, so choose a wide-angle mirror or buy a wide-angle digital camera according to their own needs. If you have bought a digital camera, but the wide-angle end is not enough, you can also buy another wide-angle lens. At present, many cameras can be attached with various filters. The effect of a wide-angle lens is expressed in multiples. For example, if you have a 35- 105 digital camera and buy a 0.6-fold wide-angle lens, the wide-angle end of the original camera can reach 35 × 0.6 = 21mm. Because the external filter has a certain impact on the imaging quality of the digital camera, and most of them are expensive, it is better to buy a digital camera with a wide-angle lens if there are many occasions to use it.
