Some basic problems about SLR camera Nikon D7000

Congratulations on joining SLR. Try to answer your question.

1. Focus and zoom are two functions. You can enlarge any function mode of the camera without damaging the lens.

2. The document is also called "aperture priority document". The user sets the aperture first, and the camera automatically determines the shutter speed according to the lighting conditions of the shooting scene and the set ISO value. So as long as you move the camera, the camera will automatically change the shutter speed according to the change of light conditions.

The full name of SLR is "single lens reflex camera". After passing through the lens, the light of the subject is refracted by the reflector to the pentaprism at the top of the camera. After being refracted twice by a pentaprism, the photographer sees an upright image through the viewfinder eyepiece.

After the framing is completed, the photographer presses the shutter to shoot. At this time, the mirror bounces up, on the one hand, to make way for the light projected onto the CMOS photosensitive through the lens, and on the other hand, the bounced mirror blocks the lower part of the pentaprism to prevent stray light entering through the viewfinder eyepiece from interfering with the normal exposure of the image.

The diopter adjuster next to the viewfinder is used for myopia, just like wearing a pair of glasses for myopia. Because it belongs to the framing system and does not participate in the exposure, it will not affect the imaging of the photo.

5. In addition to the "full manual" mode, autofocus can also be used in all modes of the camera, including automatic and other modes.

6. The P file is called "program control" mode. In this mode, the camera will set a set of combinations of "aperture and shutter speed" according to ISO settings and on-site lighting conditions, and the photographer can adjust the aperture value or shutter speed respectively. When you adjust the aperture, the camera will automatically calculate the shutter speed according to the reciprocal law to ensure accurate exposure; Similarly, when you adjust the shutter speed, the camera will automatically adjust the aperture value. Automatic mode is "fully automatic" mode, all exposure parameters are determined by the camera, and the photographer has no right to change it, just like a stupid machine.

P gear is a very useful gear, which gives the photographer the possibility to quickly adjust the aperture or shutter according to different subjects. In my opinion, I suggest you use more P files.

7. This problem is hard to say, and there are many influencing factors. For example, continuous shooting cannot be used for flash photography. You can look at the camera settings according to the instructions.

8. When switching to manual focusing, do I have to change the AF/M on the camera and the AF/M on the lens? I use a Canon camera. I think the main thing is to change the AF/M on the lens to M. I'm not sure, so I should refer to the manual.

9. Polarizing filter is not effective if it is installed on the lens. The polarizer is double-layered and its front lens can rotate. Because of the strong directivity of polarized light, it is necessary to rotate the front lens of the polarizer to effectively eliminate the polarized light that affects the picture. See the usage of online polarizer for details. Polarizers can eliminate the strong reflection of objects, eliminate the reflection of water, increase the contrast between blue sky and white clouds to make the blue sky appear bluer and increase the color saturation of objects.

In short, I hope it works for you.
