Excellent choice for entry-level cameras-Nikon D5600 evaluation

Before introducing our protagonist today, let's have a short popular science class to tell you what a SLR camera is.

Strictly speaking, the "SLR camera" we often say mainly refers to the "digital SLR camera", which is different from the traditional SLR camera. This is a concept that needs to be declared. The word "SLR" of SLR camera means "single lens reflection framing", which is an optical imaging principle and is aimed at "double-reflex camera".

/kloc-from the end of 0/9 to the middle of the 20th century, a popular dual-reflex camera with two lenses, one for framing and the other for imaging exposure. It can often be seen in film and television dramas with the background of the Republic of China.

However, due to its own shortcomings, such as large parallax between framing and imaging, poor imaging quality, inability to replace the lens, huge volume, etc., it has gradually been eliminated by the market, and now few manufacturers produce it. Nowadays, the dual-reflex camera on sale is only selling a feeling, and its viewfinder lens has no practical function and has become a decoration.

After the double-reflex camera withdrew from the historical stage, SLR cameras became the mainstream of the industry; But in fact, it is not young, and it met the world as early as the beginning of the 20th century.

The emergence and popularization of SLR can be said to be the inevitable trend of scientific and technological development. Compared with the dual-reflex camera, it has the advantages of high imaging quality, changing lenses according to different scenes and strong operability. In a word, the disadvantages of the dual-reflex camera are all advantages here.

The SLR we are talking about today is a kind of narrow-sense SLR, which should be called a single-lens reflective framing digital camera and belongs to a subset of digital cameras. It is separated from the traditional SLR camera by a very important revolutionary product-Digital Camera (DSC).

The imaging principle of traditional cameras is chemical reaction. The reason why the external color world can be recorded is that countless silver bromide particles and silver halide ions are attached to the film used. Press the shutter, the reflector is lifted, and the light shines on the film. Silver bromide particles will react with halogen anions under illumination, thus recording light wave information.

Digital cameras use optical sensors (CCD or CMOS) instead of expensive traditional films. The principle of imaging is to convert external light into analog electrical signals, and then convert the electrical signals into digital signals through the ADC integrated on the chip for storage. It is the conversion between physical energy.

SLR digital camera is a combination of SLR camera and digital camera, and it has not been a long time (less than 30 years) to really go to the world. Even Sony, which monopolized the image sensor market today, only entered the field of digital SLR in 2006.

Brand:

Today's digital SLR market has basically taken shape, with Nikon and Canon duets accounting for at least 90% of the global market share and Pentax accounting for a small part. Other big names such as Sony, Fuji and Olympus have all withdrawn from the SLR market and started to specialize in the micro-single field, which also shows that the camera market will be more and more subdivided in the professional application field and portable entertainment field in the future.

Whether you pay attention to the field of photography or not, I believe you have heard the name Nikon more or less. This camera company, founded in 19 17, celebrated its centenary in July this year. It is not easy for any enterprise to go for a hundred years. In order to remember this special year, Nikon specially launched a series of centennial models of cameras, lenses and telescopes.

Nikon has not been easy in recent years. From 12, the family went hungry every year and lost money.

With the popularity of tens of millions of pixels in mobile phones and smart dual-camera cameras, the living space of entry-level cameras is getting smaller and smaller. With the advantages of small size, portable operation and good image quality, micro-single camera is constantly impacting the mid-range SLR market and has a great potential to replace it.

At present, only in the high-end market, SLR still retains some advantages.

Even in this environment, Nikon is still "conscientious", and has successively launched entry-level and mid-range models such as D3400, D5600 and D7500 within two years.

At best, Nikon's name is Don't forget your initiative. To put it bluntly, Nikon is ignorant.

Product introduction:

This evaluation is Nikon? D5600 is equipped with18-140mm lens.

D5600 is an entry-level SLR camera introduced by Nikon Company 20 1 16+0. It is an upgraded version of D5500 and the flagship model of Nikon's current entry-level SLR. Although D5XXX series is positioned at the entry level, from the perspective of comprehensive functions and imaging quality, D5600 can be said to have stepped into the mid-range door. However, the operation logic is still designed with the idea of novice entry.

In order to let consumers not worry about the problem of matching lenses, and at the same time further benefit consumers; Some models will be sold in sets with lenses, and the price is definitely cheaper than buying cameras and lenses separately. Nikon introduced three groups of lenses for D5600, namely 18- 105, 18-55 and 18- 140. All three lenses are equipped with autofocus motor and VR anti-shake technology; While 18- 105 and 18- 140 use ed ultra-low dispersion lenses, 18-55 does not.

Overall appearance:

Because it is positioned as an entry-level model, D5600 does not use D7XXX series magnesium alloy body for cost control. However, the plastic fuselage is not so fragile. We always use wristbands or suspenders, and there is almost no "crash". On the contrary, the plastic fuselage can keep the fuselage "light".

The weight of D5600 is about 465g, and the weight of 18- 140mm lens is about 490g.

The groove handle of the right hand is covered with a layer of three-dimensional abrasive skin U, which plays an anti-slip role. It can be seen that there is no auxiliary wheel under the shutter of the mid-to high-end models. This has little effect on novices, but "old birds" who are used to playing high-end machines may feel "at a loss".

18- 140mm lens is one of the most comprehensive standard zoom lenses on the market at present. It has mute fluctuation motor, VR anti-shake, IF internal focusing technology, 12 groups 17 glass lenses (including an ultra-low dispersion lens), and the maximum aperture is F/3.5-5.6. The focal length of 18- 140mm covers the common focal lengths needed in daily life and travel photography. And 18-200mm lens have the reputation of "a mirror travels all over the world".

"Shoulder-less screen" is a major difference between entry-level models and mid-range models, and parameters can only be observed through the viewfinder or display screen.

Different from the layout of D7XXX series right shoulder screen left function dial, D5600 puts the function dial on the right side, and the left shoulder is greatly shortened, with only one strap hook.

The exposure mode is not as customized as the mid-range model, but since it is an entry-level model, it can help Xiaobai get rid of the automatic gear even after completing the task.

In terms of auxiliary impeller, the single impeller design is also less than the double impeller of the mid-range model.

Generally speaking, entry-level models have fewer functions than mid-range models, mainly shortcut keys. Shortcut is a double-edged sword, which is "even more powerful" for skilled people; For the newcomer Xiaobai, this will only increase the difficulty of learning. For example, an automatic car can increase climbing power by downshifting and increasing torque when climbing, but how can Xiaobai, who can't even drive an automatic gear, get started?

The biggest upgrade of D5600 lies in this LCD touch screen that can be flipped 270, which will provide great convenience in some special viewing angles, such as self-timer and pitching. In particular, the design that the screen can be folded inside out is undoubtedly a protection for the screen.

Touch design is also more in line with the daily operation habits of today's consumers, just like operating a mobile phone.

Product features:

D5600 is equipped with CMOS sensor in APS-C format, with 24.78 million effective pixels. At the same time, the EXPEED4 image processing engine (same as D7200) and the cam4800 module supporting 39-point focusing are adopted.

Because there is no auto-focus motor in the fuselage, it is necessary to choose a lens with a focus motor for auto-focusing.

ISO sensitivity support 1/3? EV is the step size of 100? –? 25600? Adjust between.

Exposure compensation supports adjustment between–5 and +5EV in increments of 1/3 or 1/2EV.

Shutter speed support 1/3? Or 1/2? EV is adjusted in steps of 1/4000 to 30 seconds.

At the same time, it supports three metering modes: central metering, matrix metering and spot metering.

The D5600 supports Bluetooth and WIFI wireless connection modes, and can connect to Android or ios phones through Nikon's SnapBridge function, and synchronize photos to the phones in the first time. You can also upload copyright, location and time information and send it to major social media.

D5600 also has various novel and fun special effects filters and post-retouching functions. After taking pictures, you can complete the initial "PS" directly in the camera.

Video is not the specialty of D5600, and the maximum support is only 1080P/60FPS, but it is enough to shoot some short indoor scenes.

The camera has a good tolerance, and the shadows under the trees and the highlights reflected by the water can be well preserved.

The above picture shows the sensor scores of two cameras given by the authoritative French website DXOMARK. As a mid-range model with a high D5600, D7200 still has some advantages, but the gap between them is not particularly large (84 points for one and 87 points for the other). D7200 is also the highest rated model of Nikon DXXXX series products on this website, even higher than the newly released D7500 this year.

The third landscape is translated into scenery and scenery, followed by "dynamic range" in brackets. This mainly tests the endurance of the camera. It means how many levels a picture can display from the darkest to the brightest, which is the most intuitive embodiment of the camera's landscape photography ability.

The tolerance can be calculated by the formula of "2 to the power of n", and the tolerance of D5600 is 14, which means that a photo can represent the power of 14 at most.

The second color depth refers to the number of colors that can be displayed per pixel. The higher the score, the wider the chromatogram. In this score, D5600 Nikon ranks 22nd among all cameras, and if cameras of other brands are included, the ranking is 6 1.

Conclusion:

As one of the brands with the highest market share of SLR, one advantage of Nikon camera is that it has many owners and can meet many like-minded friends. Any bug will be discovered and exposed in the first time, and lens manufacturers such as Tenglong and Sigma will also give priority to releasing adaptive lenses for Nikon and Canon. Using Nikon or Canon products as the first choice for entry has always been the tacit knowledge of the photography circle (in fact, this is nonsense, there is no other choice, so it is Pentax).

Many friends who have just entered the photography circle have the psychology of "one step in place"; In fact, it is not only in the field of photography, but also in any field. I want to buy a high-end equipment at one time to avoid upgrading in the future.

This kind of psychology is actually nonsense. In an era when the speed of upgrading electronic technology is like riding a rocket, trying to "spread one machine forever" is tantamount to carving a boat for a sword.

Today, as long as digital products are updated, they are often conceptual upgrades, such as IPHONE? X compared to last year's IPHONE? The upgrade of 7 is not only a processor hardware, but also a visual change. Last year, who would have thought that 20 17 would be a year of full-screen explosion, and who could have guessed the development trend of mobile phones next year?

Playing photography requires skill and understanding. The pleasure of buying an entry-level camera from automatic gear to manual gear is incomparable to that of buying an automatic gear in flagship machine.

Most importantly, quite a few people who buy SLR are not sure whether they really like photography. Maybe I just envy others after seeing the long guns and short guns on their chests, so I joined one myself; After playing for several times, I felt the same taste as Jue wax, so I threw the camera aside and ate it. In this case, it is better to buy an entry-level one and save some money.
