How do novices choose SLR cameras?

Bring a new formatted CF card when purchasing the machine (to prevent the wrong photo number). If you buy a stand-alone machine instead of a set of machines, you should also bring a lens.

1. Check the package. There is a canon seal, but there is no sign of being opened.

2. Open the box and take out the camera. Check whether the serial numbers on the camera body, warranty card and package are consistent. The warranty card is in simplified Chinese and the camera is licensed.

3. Carefully check the fuselage, no wear and scratches. The brand-new machine has never been exposed to sebum sweat, which is particularly clean. In particular, liquid crystal displays have no fingerprints or any traces of wiping. Check whether the opening and closing of the fuselage cover, battery compartment cover, card compartment cover and terminal interface cover are flexible and tight. The lens bayonet, the contacts in the battery box and all ports are clean, and there are no wear marks. The idea of tripod interface is clear. The machine also needs to check whether the ferrule lens is clean and dust-free, and tilt it to see whether the mirror coating is uniform and whether the contacts are clean.

4. Open the fuselage cover, and the reflector cabin is clean and dust-free. Looking at the bright place from the viewfinder, the focusing screen is clean and dust-free.

5. Pay attention to whether the plastic bag and sealing tape of the battery have opening marks, whether the battery cover is tight, and whether the battery contacts have wear marks or are very slight.

6. Install the lens, CF card and battery. Open it. When the machine is turned on for the first time, the date and time adjustment interface will appear. The LCD screen and data live screen are normal.

7. Turn all knobs (main dial, mode dial and speed control dial) and press all buttons and control buttons to achieve uniform damping.

8. Try to press each button in P mode, and the response is normal. Select other modes and the response is normal.

9. Looking through the viewfinder, you can adjust the diopter of the viewfinder at this time. The data in the viewfinder is normal, and the red dot is clear when focusing. Lower the aperture in mode A and press the preview button of depth of field to darken the viewfinder and increase the depth of field.

10.m mode, MF focusing to infinity manually, ISO 100, shooting at the highest shutter speed and minimum aperture in the dark, and displaying on LCD. The photos are all black, with no bright spots. Take a photo of light or bright place at the speed of 1s and the maximum aperture. The picture is completely white, and there are no black spots or spots on the LCD screen.

1 1.p file shooting, the shutter button is normally half pressed and fully pressed, the shooting picture is normal and the reaction speed is normal. The shutter sound is normal in continuous shooting. Emphasis is placed on inclined posters and texts, which are basically accurate. I think it is necessary to try real-life and short-film shooting.

12. Flip open the internal flash, and the flash will be exposed accurately. If there is no internal flash, you can try external flash. It doesn't matter if there is no internal flash.

13. Turn off the machine and take out the lens, battery and card. If the disassembly is successful, you can check whether the packaging and accessories are complete according to the instructions.

All right, pay the money, make out the invoice and leave. Don't forget your lens and CF card.
