What brand of SLR camera is so practical and what brand of SLR camera is so practical?

SLR cameras are getting cheaper and cheaper, and going out to play with digital cameras has become an artifact to store memories. Here are several brands of SLR cameras that I have sorted out for you. I hope you like them.

TOP 10 Nikon D8 10A

Keywords: Quan Huafu astrophotography

Reason for listing: D8 10A is a model specially designed for astrophotography based on D8 10. Compared with D8 10, the optical filter in front of D8 10A image sensor has a 4 times higher H-α ray transmittance, so it can clearly and realistically restore the red color of H-α rays from nebulae and galaxies. However, when it is used for ordinary photography, when shooting or shooting a general object with near-infrared wavelength and high reflection under a large number of light sources, the obtained image may be red, which makes Nikon D8 10 only a few, and its appearance has broken Canon's monopoly in this field. At the same time, D8 10A is equipped with Quan Huafu sensor, which is more "tall" than EOS 20Da and EOS 60Da previously introduced by Canon.

TOP9 Panasonic LUMIX GX8

Reason for listing: Panasonic LUMIX GX8 is equipped with a newly developed 20.3 megapixel Live MOS image sensor, and its effective pixel reaches the highest value of M4/3 system, which is called "the highest image quality ever of LUMIX G digital camera" by Panasonic. High-speed continuous shooting, high-sensitivity image recording with the highest ISO25600 and wider dynamic range are realized. In April this year, Sony Semiconductor official website listed many new sensor products, among which the 20-megapixel 4/3 sensor IMX269 was impressively listed. I think Panasonic LUMIX GX8 is just the first person to eat crabs, and this kind of sensor will spread rapidly in M4/3 system. It can be predicted that the new Olympus machine will also break through the bottleneck of16 million pixels next year, reaching 20 million.

TOP8 Nikon 1 J5

Keywords: about 20 sheets/second AF continuous shooting.

Reason for being on the list: Nikon 1 has been known as the "final battle" since its birth, and continuous shooting's focusing performance in past dynasties has been outstanding. This series has been developed to Nikon 1 J5, equipped with 1 inch back-illuminated CMOS and 105 phase detection autofocus point, which can realize high-speed continuous shooting (full-resolution output) and continuous AF AF of 20 frames per second, which is beyond the reach of other SLR cameras.

TOP7 Sigma dp0 Quattro

Key words: new Foveon X3 sensor, 14mm lens.

Reason for listing: Sigma dp Quattro series is equipped with a new generation of Foveon X3 image sensor. The first four pixels of the sensor correspond to a single large-area pixel in the middle layer and the bottom layer respectively, forming a brand-new three-layer structure of "1: 1: 4". Light and dark information is mainly recorded by the upper layer, and color information is captured at the same time. The middle layer and the bottom layer capture color information respectively. Through arithmetic processing, the color information recorded in the middle layer and the bottom layer is restored and combined with the light and dark information captured by the corresponding pixels in the top layer, so that each pixel can obtain the corresponding light and dark information. Based on the vertical color separation principle of three-layer structure, the light and dark information recorded at the top layer is transmitted to the following two layers to realize pixel promotion and high-speed data processing. However, the new Foveon X3 image sensor has the same function as the dp Quattro series.

The Dp0 Quattro is equipped with a super wide-angle fixed-focus lens14mf4 (equivalent focal length is 2 1mm) specially developed for the new sensor. The lens adopts four FLD fluorite low dispersion lenses and two SLD special low dispersion lenses to correct the lens chromatic aberration. At the same time, two aspheric lenses are used, including 1 double-sided aspheric lens. When shooting at infinity, the focal length of 14mm of dp0 Quattro is the first time in dp series. Ultra-wide angle meets the needs of users to shoot scenes, and can fully demonstrate the advantages of color resolution of Foveon X3 image sensor.

TOP6 Olympus E-M5II and Pentax K-3 II

Keywords: high resolution mode pixel offset resolution system

Reason for listing: 5-axis anti-shake can be said to be Olympus's unique stunt. In the generation of E-M5II, 5-axis anti-shake is not only suitable for still images, but also for video shooting (E-M 1 only 3 axes). In video shooting, M-IS 1 anti-shake mode is a combination of 5-axis optical anti-shake and digital anti-shake while M-IS2 mode only uses 5-axis optical anti-shake. Olympus also extended the high-resolution mode by using a 5-axis anti-shake system. The camera took 8 images and moved the sensor by 0.5 pixel at a time. Then eight images are combined into an ultra-high resolution image (40 million pixels JPEG, 64 million pixels RAW).

In addition, Olympus has added depth of field synthesis mode and focus surround exposure mode in firmware version 2.0. The former is to take eight images with different focal lengths at a time and automatically synthesize a high-definition photo; The latter took 999 images with different focal lengths, and used image processing software to produce images with greater depth of field than the depth of field synthesis mode (8 images). These two functions are very useful for product photography, architectural photography and macro photography.

Pentax K-3 II

Reason for listing: Pentax K-3II adopts the method of slightly staggering each pixel in the image sensor unit and shooting four times. Using the super-color information of 24M×RGB, the "pixel offset resolution system" of Juck Zhang HD image is generated. The resolution and color reproducibility can be improved, and ultra-high resolution images can be obtained when shooting static objects. High-sensitivity noise is also greatly reduced, and theoretically there will be no pseudo color. Using an electronic shutter when shooting can suppress camera shake. Pentax, like Olympus, also made a fuss about the anti-shake of the fuselage. The difference between them is that Olympus focuses on "multiple" in order to increase pixels, while Pentax focuses on improving the imaging quality of unit pixels and focusing on "truth".

TOP5 lycra q

Keywords: Quan Huafu RX 1 competitors

Reason for listing: Leica Q is a portable digital camera from Quan Huafu. The camera adopts Leica Summilux 28 mm f/ 1.7 asph, has a 24-megapixel Quan Huafu CMOS sensor, with a maximum continuous shooting of 10 frame/s and a built-in 3.68-megapixel electronic viewfinder. In addition, it also supports Wi-Fi and NFC. The emergence of Leica Q broke the monopoly pattern of Sony RX 1 series and gave users who like high pressure a choice. In terms of parameter performance alone, Leica Q can't compete with RX 1RII.

TOP4 Sony RX 1RII

Keywords: adjustable olpf

Reason for listing: Sony RX 1RII adopts Quan Huafu Exmor R CMOS, with an effective pixel of about 42.4 and a built-in low-pass filter. The camera has a 399-point phase detection focus, and the built-in T* coated XGA OLEDTru-Finder can pop up the viewfinder, which is convenient for users to take pictures under strong light. From the hardware parameters alone, RX 1RII is like stuffing the core hardware of A7RII into RX 1. The highlight of this product itself is the adjustable optical low-pass filter, which is different from Pentax's use of anti-shake components for physical jitter. Sony started with an optical low-pass filter. A filter has the effect of three steps. Photographers can manually adjust the image resolution and the balance between Moore and pseudo color to match the subject.

TOP3 Leica SL

Keywords: list of giants

Reason for listing: Leica SL is the brand's first Quan Huafu mirrorless camera and a new milestone for Leica cameras. Leica SL is the first electronic viewfinder with Leica EyeRes technology. The waiting time is lower than the perception time threshold, and the resolution is 4.4 million pixels. Leica SL uses a 24 megapixel CMOS Quan Huafu sensor; Shutter speed from 30 minutes to 1/8000 seconds; Sensitivity up to ISO 50,000. This camera is also equipped with Leica Maestro II series processors, which can realize high-speed autofocus, with a maximum speed of 1 1 continuous shooting per second and support 4K 30p video recording. In addition, Leica SL has a 2.95-inch display on the back of the machine. You can flip the camera at 170 or navigate through the touch screen menu. In a word, the appearance of Leica SL is similar to Leica Q, without Quan Huafu's anti-market to break Sony's monopoly, giving users a "high-quality" choice, and the body performance of Leica SL also has amazing performance. Fast focusing and clear viewfinder make users feel the experience of high-end SLR. As a "mighty" model of Leica SL in mirrorless cameras, it has been ridiculed by many users as a "blockbuster" (as opposed to Sony's "microchip"). However, the larger fuselage gives a better grip and heat dissipation space, which is an ideal solution at present.

TOP2 Canon EOS 5DS/EOS 5DSR

Keywords: 50 million high pixels

Reason for listing: Canon EOS 5DS and EOS 5DS R applied Quan Huafu CMOS with about 50.6 million effective pixels independently developed and produced by Canon for the first time. The emergence of Canon EOS 5DS and EOS 5DR is as significant as Nikon D800 and D800E. Canon pushed Quan Huafu's effective pixel to 50 million, surpassing Sony and Nikon in one fell swoop and becoming the leader. Compared with Nikon, Canon's scheme around high pixels is more mature, and it has developed technologies such as mirror vibration control system and new "exquisite detail" photo style.

TOP 1 Sony A7RII

Keywords: back-illuminated Quan Huafu 5-axis anti-shake 4K 399-point phase detection. ...

Reason for listing: A7RII is Sony's first camera with Quan Huafu Exmor R CMOS back-illuminated sensor. The camera has about 42.4 million effective pixels, 399 phase detection focus points, built-in 5-axis anti-shake system and 4K video recording. In addition, other performances have also been improved, such as a 500,000-life low-impact shutter, a better EVF, continuous shooting at 5 frames per second under AF, and support for silent shutter. Sony claims that this camera "opens the way for the coexistence of high pixel, high sensitivity and high-speed processing". Although this camera doesn't really achieve a perfect three-point balance, at this stage, A7RII is indeed the undisputed king of A7 series and has become the "popular spicy chicken" of 20 15.

How do novices choose SLR cameras

First, let's look at the purchase cost. Compared with these three places, the computer city is the place with the lowest purchase cost, because the earliest sales of digital cameras originated in the computer city, and young players who are keen on DIY and computer accessories became the earliest buyers of digital cameras. Therefore, merchants who buy digital cameras in computer city generally don't charge too much, and there are many digital camera dealers in computer city, and the competition is fierce, so it is difficult for merchants to sell at high prices. Home appliance stores refer to places like Gome and Suning. The cost of buying digital cameras is slightly higher than that of computer city, because the environment of home appliance stores is generally better than that of computer city, and the rental cost of stores is higher. High end shopping
