Analysis on the difference between wide-angle and telephoto of SLR

Analysis of the difference between wide-angle SLR and telephoto 1 What's the difference between telephoto camera and SLR?

1, the imaging quality of SLR cameras far exceeds that of telephoto cameras (the so-called telephoto camera is actually a card machine with a long lens focal length), because the area of SLR photoreceptors is ten times or even dozens of times that of telephoto cameras (the area of photoreceptors determines the imaging quality), and even in very dark environments, very clear and beautiful photos can be taken.

2. SLR cameras can replace lenses with various focal lengths (such as fisheye, ultra-wide-angle, wide-angle, standard, medium-focus, telephoto, ultra-telephoto, macro, etc.) to meet various shooting needs, greatly expanding the shooting range and showing the charm of photography art well.

3. Manipulation performance of SLR camera (such as reaction speed, continuous shooting speed, focusing speed, battery life, dustproof and waterproof, impact resistance, service life, etc.). ) far superior to telephoto camera, it is an ideal machine for professional photographers and enthusiasts.

What are the advantages of telephoto digital cameras?

1, powerful 65x zoom capability.

2. The addition of hot boots increases the practicality of the camera.

3, quick door line jack, maximum humanization.

4, equipped with WiFi and NFC functions

5. The overall design is compact and the details of the fuselage are well handled.

6, representing the peak of digital camera technology, the most commonly used camera category in professional field, with high control and shooting efficiency. At present, the 135 camera with the best image quality is also from the SLR camera.

7. Cheap price, high portability and fashionable design elements can be easily combined.

8. High degree of automation, simple operation and interesting functions.

9, feel good, relatively portable, high-power zoom lens with high practicality. The price is also cheaper.

10, the longer the focal length, the shallower the depth of field, which is the same as the larger the aperture. The advantage of shallow depth of field is to highlight the subject and blur the background. I believe that many fans pursue shallow depth of field effect when taking photos, making the photos more professional.

Analysis of the difference between wide-angle SLR and telephoto (2) About telephoto;

A telephoto digital camera refers to a model with a large optical zoom factor. The larger the optical zoom factor, the farther the scene is photographed.

The main feature of telephoto digital camera is actually similar to the principle of telescope, which changes the focal length through the movement of the lens inside the lens.

The benefits of telephoto come into play when we shoot distant scenery or photographers don't want to be disturbed.

About wide angle:

A wide-angle lens is a photographic lens with a shorter focal length and a larger viewing angle than a standard lens. Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance.

For example, when taking a group photo, the ordinary lens should be farther away from the subject (the photographer retreats) to take all of you. But if you can't stay away from the subject or be limited by the venue indoors, you can't shoot everyone. At this time, a wide-angle lens can solve this problem.

Simply put: a wide-angle lens can shoot a wider picture at a shorter distance.

Recommend Canon brand with the first market share between 2000 and 3000 yuan.

First, Canon IXUS 80 is

Reference price: 1660 yuan [Beijing] 1730 yuan [Shanghai] 1730 yuan [Guangzhou]

Recommended reason:

8 million effective pixels

It is an optical image stabilizer (optical image stabilizer)

Stylish and compact, precision-made stainless steel metal alloy fuselage

The LCD screen adopts the "Xuanjing II" LCD with a resolution of 230,000 pixels, which has a very delicate display effect and stronger wear and dust resistance.

A new DIGIC III digital image processor

Motion detection technology.

Innovative "sunset" mode.

Second, Canon IXUS 860 is (SD870 is)

Reference price: 2 190 yuan [Beijing] 2 180 yuan [Shanghai] 23 10 yuan [Guangzhou].

In addition to all the advantages of Canon IXUS 80 IS, three highlights have been added:

1, 28mm wide-angle lens can shoot a wider scene (Canon IXUS series first card machine with wide-angle function)

2. It is a very practical "face recognition function" (face priority focusing), which allows beginners to easily take clear portrait photos.

3. The LCD screen is upgraded to a 3.0-inch large screen.

Third, Canon A650 is fully manual (LCD screen can rotate).

Known as "a powerful machine with everything!" Canon A650 is Canon's first12 megapixel A series camera. Compared with the previous generation A640 (which once sold well), A650 not only improves the pixels, but also has a strong performance upgrade. The optical zoom is increased to 6 times, and anti-shake and facial recognition functions are added. Of course, the traditional A650 has complete functions, rich modes and excellent manual performance. It can be said that A650 IS is the undisputed king of the new generation of manual practicality!
