Nikon D5200 with 70 300mm lens is equivalent to how many times the zoom

On a DSLR, there is almost no point in discussing zoom factor, you are affected by the small DC.

For example, Sony RX100 has an equivalent focal length of 28-100mm, then its zoom factor is 100 28 = times, and 70-300 zoom factor = 300 70 = times, however, 70-300 is much farther than ordinary card machines, equivalent to 450mm at the 300mm end, which is similar to the telephoto end of many telephoto machines. The shortest 70m end of the 70-300 is equivalent to 105mm, which is also slightly longer than the RX100.

To put it simply, on the SLR, 300mm is already very long, and the lens longer than 300mm is basically worth a lot of money, and it is basically used in professional fields such as ecology and sports photography.

In addition, the 70-300 lens is very cheap, and Nikon has a 70-300g lens for only 700 yuan. But landlords are advised not to buy these things. Be sure to buy Nikon's own 70-300VR or Tamron's 70-300VC.

300 70 I'm a little water ratio, meow, meow.

Magnification looks, multiply. The depth of field is the same as the full outfit.

1. First of all, I want to tell you that how many times the zoom is the ratio of the longest focal length to the shortest focal length of a zoom lens, which is not directly related to the focal length of 500 mm, let alone comparable.

The camera's 500mm lens is a super telephoto lens, which means a telephoto lens - you will be very clear when you shoot distant targets. The actual focal length of the lens of the average digital camera is relatively short - the actual focal length has not yet reached 50mm, let alone compared to a 500mm super telephoto lens. The equivalent focal length of 500mm is not the same as the effect of a lens with an actual focal length of 500mm.

3. Ordinary digital cameras have a small sensor area - much smaller than the full-frame 36x24mm, so even if the lens with a short focal length is used in this kind of small-area camera, its field of view angle is also very small - the field of view of the telephoto end of its lens is equivalent to the field of view of a telephoto lens with a very long focal length or even a super telephoto lens, but its magnification effect, especially the resolution, will not become larger because of the small sensor area, that is, there will be no real telephoto, super telephoto lens resolution and magnification effect. The so-called equivalent focal length is only due to the smaller field of view, the image on the smaller sensor occupies a large relative area, the resolution and magnification effect are only the level that its actual focal length can achieve, and the imaging is even worse - because the resolution is not high enough and the image is not sharp - the image is more blurry. Therefore, it can be said that the so-called equivalent focal length is only the field of view of the corresponding focal length, not the resolution of the lens that can be equivalent to the corresponding focal length!!

The magnification is not directly related to the focal length.

1 mm to 500 mm is 500x zoom.

100 mm to 500 good wood is 5x zoom.

The average home camera is almost equivalent to 24mm-28mm, and 500mm is almost 18-21 times

The Nikon 70-200 is a constant aperture, while the 80-400 is not constant (, so the image quality is better than the 840 at the same focal length. In terms of carrying (77mm filter), documentary street sweeping, scenery, and portraits are the first choice. The quality of the 840 is actually good, but it is rarely used in general use, it is a bit short to shoot birds, the aperture is also small, and the quality of the aperture decreases when it is opened to the maximum.

I'd recommend the 70-200 lens, but the new AF-S Nikkor 70-200mm F FL ED VR

**Not expensive, about 13,000. I wonder if I can help you?

Just describe, look at the use. Usually neither of these lenses is used. If it works, the former is recommended. The picture quality is a little better.

The D500 with a 24-70mm lens is no problem.

The D500 was launched in early 2016, and although the effective pixels are not high, only 20.88 million, it is characterized by a focus on speed: the maximum shutter speed is 1 8000 seconds, the continuous shooting speed is 10 frames, and it can take up to 200 consecutive shots at a time to store in the RAW format of 14-bit lossless compression**, using the same Expeed as the flagship model D5

30p) animation. As can be seen, the D500 is specially developed for shooting high-speed moving objects, such as sports competition photography.

Because shooting high-speed moving objects requires a high shutter speed, especially in sports, many shooting environments are indoors, if the lens aperture is not forced, then there will be insufficient quality, or blindly improve the ISO and affect the quality.

The D500 is equipped with a large-aperture lens, which can better play the advantage of high speed.

Nikon. There are two 24-70mm lenses, one of which was released in 2007.

F ED, the other is the F that was launched in 2015

EDVR,**The main difference is 3 points: one is the use of electromagnetic aperture, which can achieve more stable automatic ** control even during high-speed continuous shooting, the second is the addition of VR shock absorption function, which can provide an effect equivalent to 4 stops of shutter speed increase, which is more suitable for shooting high-speed moving objects, and the third is the use of the latest aspherical ED lens and 1 high refractive index lens, which is Nikon's first lens with aspherical ED glass lens. It can effectively reduce the color edges, horizontal chromatic aberration of the edges, coma flare and other lens aberrations, and effectively correct distortion and spherical aberration

EDVR is better suited for the D500.

To sum up, it can be seen that the D500 body with 24-70mm lens size is still good. Of course, for shooting sports, there is only a 24-70mm lens, and the focal length is obviously not enough, so it is best to use a blind 70-200mm lens
