What's the difference between Nikon D5 100 and D90? I am a student and want to ask my friends who have used SLR.

Several advantages of D90 over D5 100:

The D90 has two thumbwheels, so you can set the aperture and shutter at the same time when you use full manual exposure.

The D90 uses a pentaprism with high magnification. In the viewfinder, it will be brighter and bigger, and autofocus has little effect, but manual focusing has advantages.

D90 can import curves, and can directly imitate other people's colors, eliminating the later period;

The skeleton of D90 is alloy, which is stronger in theory, but only in theory. If you are interested in this, you can search for a video by yourself with the keyword "Nikon, Canon, Destructive Test".

The D90 is bigger, the skin is more textured, and the feel is naturally better.

The D90 has a shoulder screen, which saves more electricity and can still see the parameters clearly in strong sunlight.

The D90 has a body motor, while Nikon's old lens has no motor, so it is impossible to autofocus the D5 100 body.

The D90 has more exposure compensation files, so when you choose aperture/shutter priority mode, you have more space instead of switching to full manual exposure.

The D90 is equipped with a wireless flasher, so a flasher can be omitted when an external flash is used.

D5 100 is stronger than D90:

Like D7000, Pentax K5 and Sony NEX5N, this new sensor has higher tolerance, higher sensitivity, higher pixels and better overall image quality.

When shooting in a low position or grabbing shots in a crowd, the rotating screen has more advantages;

Digital filter, you can shoot some special effects without later;

1080P full HD camera, and continuous focusing (D90' s 720P camera is very poor in practicality, which can be ignored by ordinary players);

It should be understood that the advantages of the D90 are mainly in manual functions, such as manual focusing and manual exposure, while the backlight resistance of the shoulder screen is actually nothing. Because your eyes have to leave the viewfinder to see the shoulder screen, you can see the LCD screen at a slightly sideways angle, and it is bigger. As for the focusing system (11focus including1cross focus) and the shutter system (maximum shutter 1/4000 seconds, continuous shooting speed of 3 or 4 frames per second), both are similar. D5 100 processor is still a new generation.

A real midrange machine has multiple cross focus points, the highest shutter speed is 1/8000 seconds, and the continuous shooting speed is more than 5 frames per second. However, the D90 is only more "professional" in appearance, and its snapping ability is really not as good as that of the mid-range machine. Nikon's professional machines (D7000, D300S and D700 or above) have black frosted shutters, not D90 and D5650.

More people choose the D90 because it looks "professional". For most players, D5 100 is much more practical, and the image quality is obviously improved.

After talking about the camera,

Actually, someone upstairs misunderstood. Nikon's AF-S 18-55mm f/3.5-5.6 G VR has better picture quality and similar resolution than AF-S18-105 mm f/3.5-5.6 g EDDXVR. The former has shallow dark angle and weak dispersion and shooting. The advantages of the latter are: wider focal length, better workmanship and stronger (more professional) body. The former is much cheaper because of its simple structure and low cost, but it is not necessarily cheap. If it is really tangled, choose D5 100 single camera and 18- 105 lens.

As for D5 100, there is no fuselage motor. Actually, you don't have to care too much about this. Now Nikon's lenses are basically equipped with motors. Although the old D-size lenses are cheap, many of them are not optimized for the digital age, and their actual performance is not as good as the new G-size lenses. Besides, is the G lens on the market really not enough for you?

Kengo is the most popular choice for protective glasses. You can use a multi-layer coated UV mirror or pro 1D (remember to distinguish anti-counterfeiting). If you choose the lens of 18-55 (this is enough scenery), you can do without protective glasses. Anyway, lenses are cheap, and protective glasses that are too cheap are not as good as bare metal. . .

Generally, a tripod made by Bainuo Travel Angel or Sirui Admiralty around 800 yuan (including Yuntai, detachable monopod and reversible tripod) is enough. Too good a tripod is a waste.

It depends on the camera bag. A product of about 100 yuan (imitation of National Geographic) is quite good. One machine with two mirrors (or 1 camera 1 mirror 1 flash) is enough, which is at least more reliable than an unknown imitation and can be verified in official website. A more low-key way is to choose a satchel of similar size, and then go to Taobao to choose or customize the inner bag, which is almost protective and much more comfortable. It's not very smart to buy an entry-level machine 13. Real masters are very low-key.

Back to your question, digital products are changing with each passing day. The D90 is really not excellent these days (it just looks more like a professional machine, but it is like this inside). D5 100 is a product launched by Nikon market segment, which is more suitable for the public.

Are you sure about D90?

Do you often use manual focusing and manual exposure? Aperture shutter priority has met more than 99% of the shooting needs.

You just focus on the video manually? It's strange that you haven't practiced for a few years, and you don't have a professional and stable instrument to shoot videos, and you don't shake when focusing manually.

Will you spend thousands of dollars on two external flashlights and light stands? Even if you really know, it will cost thousands of dollars, and the exhibitionist is only a few dozen dollars.

Do you specialize in making used old lenses? Second-hand goods are very deep.

It was awesome to buy Nokia N95 four years ago, but it is absolutely stupid to buy it now. Besides, the D90 is not as flagship as the N95 in mobile phones.

Besides, if you buy a D90 set of machines with a budget of 8,000 yuan, it is not enough to buy accessories. Accessories are really important.
