Nikon d90 price. I don't know what to pay attention to when buying the first SLR. Please tell me. Thank you. I'm numb after reading the introduction online.

D90 is a classic veteran, and now it has been delisted, with the highest cost performance. The current price is around 7000.

Single machine 5200 up and down.

It is still quite recommended. Let me briefly say:

Advantages:

1, the price, Nikon's mid-range SLR was the most cost-effective in the delisting period, and it was the king of that year!

2. The focusing system and image quality have a good performance, inheriting the sharp and transparent characteristics of Nikon.

3, the body motor is very reliable, and the 920,000 pixel screen is also more reliable.

Disadvantages:

1, the model is a little old, and the video and image quality are not as good as those of D7000 and D3 100 of the new processor.

2. The endurance is not as good as the new D7000.

3. It's a half-width machine, and the high noise is not as good as the new D7000, D3 100 and so on.

There are many important parameters of SLR, the key depends on what you do with SLR! List some tips, I hope you can find the most useful parameters for yourself and then find the most useful machine!

SLR is very expensive, so you should choose it slowly according to your own needs.

There are too many parameters in SLR. List a few key parameters that you are worth spending money on:

1, photosensitive element size: rookie will say that the higher the pixel, the better; The old bird will say that the bigger the photosensitive element, the better; The larger the photosensitive element, the better the performance at high sensitivity; The higher the tolerance; CMOS is better than CCD.

Remember: the higher the pixel, the better. Pixels are for reference only, and the imaging quality is related to the fuselage and lens!

2. Focus system: The more focuses, the better. Similarly, in the case of focus, the more cross focus, the better the performance. Focusing system is very useful for snapshot and snapshot, and it is one of the main parameters of SLR.

3, the fuselage, small, plastic is relatively low-grade, large, metal is relatively high-grade, if you are really confused about various parameters, this is a certain criterion.

4. Do you have a body focusing motor? If you have a focus motor, you can focus automatically. Otherwise, you can only use a lens with a focus motor or focus manually. This determines whether you can use a low-end lens with high cost performance. Lenses with motors are more expensive, slower in focusing than the fuselage, and more upscale. You have to think it over.

5, viewfinder coverage, this is optical performance, very important! The bigger the scope, the better. High-end machines are basically 100%.

6. The continuous shooting speed determines the capture performance, and the processor model affects the final image quality (the newer the processor, the better).

7. There is a qualitative difference between a full-frame machine and a half-frame machine in terms of image quality and latitude, which is also very important for lens selection.

8. Whether you have the money to take good photos is the decisive factor of the final photo quality.

9. Anti-shake of fuselage: It is convenient to have an anti-shake fuselage.

10, high sensitivity performance: night shooting (especially sunrise and sunset) is very important, which depends on the specific contrast of the fuselage, and the actual effect has little to do with the parameters.

Features that are not worth paying for:

1, the continuous operation of camera CMOS will affect the service life, which is of little practical significance. After all, you bought a camera, not a DV, right?

2, LCD resolution: photos look the same on the computer, after all, you will eventually use the computer instead of the camera to appreciate the work.

3. The shutter speed is too fast: for example, there is little difference between the shutter speed of 1\4000 seconds and the shutter speed of 1\8000 seconds, which is used to shoot bullets through apples or something.

4. Dust removal system: Without good habits, even the best dust removal system should be honestly cleaned after sale.

5, whether to flip the screen: it is basically a gimmick.

6, feel, appearance: different people have different views, everyone's feelings are different, you feel the "professional" body, others may feel "heavy".

7. the choice of n and c: if you choose the novice price, it will be almost the same. As a Canon Black, I think the low-end Nikon is kind, and if you play high-end MM, you should choose Canon. The low-end Pentax is cost-effective and worth considering (purely personal point of view).

If you're talking about the store experience:

Check the machine, you need to know how JS will fool you, and the parts JS will usually change: new machine to prototype, refurbished machine. The original battery of the fuselage is replaced by a counterfeit, deputy factory, or through various packaging and gifts, high-priced cameras are sold in disguise to earn huge profits.

Let's talk about the inspection method and the general process of purchase:

1. First of all, the new machine seal brought by the boss should be carefully observed before unpacking, especially the transparent tape on the bottom and back to see if there are any signs of opening. If there are obvious traces, be careful. If not, ask the boss to change it.

Reason: Some JS will use a hair dryer to heat the scotch tape, open the box and replace it with a new machine (such as a prototype) to sell to consumers.

2. After unpacking, check the chassis, instructions and fuselage numbers to ensure that the three numbers are consistent. If they do not agree, ask for a new one immediately. Some JS machines cannot replace the case number and instruction number at the same time. If it is powered by a non-AA battery, remember to check whether the battery is original.

Reason: Some unscrupulous JS will replace the valuable original battery with the one produced by the vice factory, and the profit earned by one battery is enough for a camera.

3. Check the appearance after getting the camera. The new machine smells like industrial disinfectant, so it should be recognized. Then check the lens cover and battery box for signs of wear. If so, be careful. I think it has been replaced. Finally, check whether the accessories are complete.

Reason: After the prototype and refurbished machine are unpacked, the unique smell will disappear when they leave the factory after being touched by people. For cleaning, refurbished machine manufacturers often use civil (that is, medical) alcohol to clean or not. This should be easy to identify. Because both the prototype and the refurbished machine have been used, there will be wear marks in key places, which can never be fake.

4. After checking, it's almost ready to boot. Generally speaking, when a high-end camera is turned on for the first time, you will be prompted to set the time and date. If not, be careful. After turning on the computer, do two things: a take photos when it is completely black and observe whether there are bright spots on the LCD screen. If there are more than three, ask the boss to change one. B. Take a white photo and check whether there are dark spots on the LCD, as above. Then you install the memory card, battery, and check whether the buttons such as focus, camera function and flash are working properly.

Cause: Check the LCD on the machine for bright spots and bad spots.

5. No problem. Remember to ask JS to issue an invoice, fill out a warranty and so on. Take the machine and you can go. After you get the new machine, use it as much as possible. If something goes wrong, you can replace it.

Handle JS:

1, do not accept any packaging, as long as the official standard, do not accept any gifts when bargaining, remember, wool is on the sheep, you may often spend hundreds of dollars on the fuselage, and buy a "gift" that costs less than tens of dollars.

2. After finding the machine, JS will probably find an excuse that it is out of stock, and then recommend one to you (because they think it is unprofitable). At this time, remember to hold your ground and pay when you see the goods, otherwise you will probably be fooled.

3, walk a few more, don't be afraid of being tired, talk about all the conditions before saving money. Before saving money, you are a grandfather, and after saving money, you may become a grandson, so you can't be a cheap JS. It is king to read more and compare more.

I hope you can choose a camera that you are satisfied with!
