Is Nikon D80 or D3000 better? Consult a professional expert.

Let's just say that D3000 is better than D80 because it uses Nikon's first generation EXPEED processor, and the picture quality is definitely better. But their CCD is the same, 6.5438+0.02 million pixels. So the picture quality of D3000 is not much better than that of 80, and the sensitivity is the same, from 100- 1600 to 3200. Continuous shooting also has 3 frames per second. But the display screen of 3000 is bigger than 80, but the number of pixels is the same, all of which are 230 thousand. 80 has a shoulder screen, you don't need to look at the display screen to adjust parameters or anything. However, as the lowest entry machine of Nikon, the 3000 has no shoulder screen, and it has to pass through the display screen. 80' s battery life exceeds 1000. In the worst case, the battery life close to 2000.3000 is nearly half less than that of 80. The point is the same, 1 1. But D80 has many extended functions, such as multiple exposures. More importantly, the post-80s generation has a body center of gravity, which is the most weighty. Because Nikon has some classic lenses that don't have G-head versions-such as 85F 1.4 85F 1.8, 17-35 F2.8, etc. This directly restricts you from buying lenses. So 80 is still very advantageous ~

Suning is expensive because he wants to buy it from the dealer first and then put it on the counter for you to buy. Of course, the price will be raised in the middle. But Taobao is different. Taobao is equivalent to the dealer selling it directly to you. Of course, the latter is cheap, but there are many parallel imports. I bought genuine goods at the counter. Save money or worry, it depends on the landlord.

To sum up, if the landlord intends to engage in photography for a long time, he should buy an 80-year-old to practice. Contact the second-hand camera market or suggest that you bring a knowledgeable friend. If it's just a family pat, 3000 is more than enough.

The following are some great points that I have summarized to buy second-hand cameras, which can prevent you from losing money to the greatest extent.

First of all, you have to prepare:

1, notebook computer, because of testing the bad spots of photosensitive elements, focusing accuracy and shutter times, it is important to install DeadPixelText software (hereinafter referred to as DPT) and light and shadow magician first.

2. Card reader and empty memory card (D80 is SD card), which are used to transmit photos when testing the camera.

3. Triangular ruler. Used to check the focusing accuracy of the camera.

4. A piece of red, a piece of white and a piece of black cardboard are used to detect the defects of the photosensitive element.

5. If possible, bring a flash to test the compatibility and actual control effect of the camera flash, and then bring a lens to test the compatibility with the lens.

6. money.

Second, let's go

Third, classified inspection.

0. Carefully check whether the camera is in good condition, damaged or missing parts. And observe whether the viewfinder, reflector and shutter are damaged.

1, detect the defect point of photosensitive element:

First, adjust the camera resolution to the highest (d80 is 10.2 million), and cover the lens cover and eyepiece cover. Set it to M (manual) stop, maximum aperture, manual focus, use the wide-angle end of the lens and set it to the maximum ISO sensitivity, take all-black photos with different shutter speeds and input them into the computer, turn on DPT, set the brightness higher than 60 lumens as noise point, and set the brightness higher than 250 lumens as bad point, and you can check.

2, check the LCD bad point, LCD is the camera screen, although his bad point will not affect the photo, but it will affect the mood and thinking.

Take a photo of each of the three pieces of cardboard with the camera, then look back at the photo and check the screen carefully.

3. Check the accuracy of focusing.

Put the ruler on the table, and then aim the camera at the ruler at a 45-degree angle to shoot. Set the camera to the focus selection function and the maximum aperture in advance, and shoot a certain scale on the scale. Then input the photos into the computer. If the scale on the predetermined focus is clear, there is no problem with focusing. If the scale is blurred and the previous scale is clear, it means that the camera or lens is out of focus. In order to test more accurately, it is necessary to test at different distances, multiple scales, wide-angle ends and telephoto ends one by one, and at the same time, none of D80' s 1 1 focus points can be missed.

4, automatic white balance.

Take photos under fluorescent lamp, sunlight, incandescent lamp, night and other light sources to see if there is a big difference with the actual situation. If the difference is small, it means that the white balance optimization of the camera is excellent.

5. Shutter times

This is very simple. Take the first photo you took to the computer and open it with the magic hand of light and shadow. In EXIF information, the bottom line is. If you find that the shutter times are few, but the machine is very old, you should be careful, because the shutter times of 80 will automatically reset after 65536 times. I don't want this machine, it's too old. 80 shutter life 100000.

6, metering.

Set the camera to the P (automatic) position, with the lowest sensitivity and compensation of 0EV, and take several photos continuously. Test on the computer, one by one to see if it is too bright or too dark. In the meantime, see how dark it is. Pay attention to all three kinds of photometry.

7. lens. . (If you need to buy)

Turn the zoom focus ring to see if it is too loose or too tight. Open the front cover and observe the lens. It should be dark and not reflective. Open the back cover again to see if there is too much dust or oil pollution or even mildew in the lens group. Observe halos and bubbles. If there is a filter, the flatness of the filter can be judged by looking obliquely at whether the scene reflected by the filter is deformed. Finally, look at the outermost lens for scratches, and then look at both sides of the filter to see if the coating is intact.

8. Check the invoice.

9. Check whether other accessories are complete and ask the place of purchase.

Fourth, decide whether to buy or not according to the situation. And negotiate the price.
