Nikon d750 lens

1, the biggest difference between the two lenses is the aperture. The aperture of 24-70 is F/2.8 Evergrande aperture, which is a whole level larger than 24- 120. This level of aperture determines that 24-70 has blur ability that 24- 120 does not have and a higher shutter speed under the same lighting conditions, which means it is capable. Under the same photoelectric configuration, the price difference will be several times: the price of 24-70F/2.8VR with anti-shake is about 13000, and the price of this 24-70 you mentioned is about 9000, while the price of 24- 120F/4VR is only about 4000.

2. The larger the zoom ratio of the zoom lens, the less the image quality can be guaranteed. The zoom ratio of a zoom lens, which can be called the king in the mirror, is generally around 3. Both N and C call the constant aperture of the three lenses, F/2.8 of 16-35, 24-70, 70-200, the big ternary, and F/4 the small ternary. Although the 24- 120 coke joint has a long section, it is only used as a convenient hanging head.

3.24-70 is the most commonly used zoom lens for full-frame machines. No matter which company is in charge of Hua Dan, it will apply the most advanced technology to this lens. For example, the 24-70 with anti-shake mentioned above (full name is AF-S 24-70mm f/2.8E ed VR) is the first nikkor lens with aspheric ED glass lens.

It is impossible for a SLR camera to have only one mirror, otherwise it is meaningless to pay the bill backwards. Buying 24-70 can lay the foundation for building a large ternary lens group in the future, but if you don't plan to invest too much, you can also consider using 24- 120 as the hanging head, and then plan to buy a fixed-focus lens with a large aperture of 50 or 85. Besides, the 24-70 lens you mentioned is not anti-shake. Beginners try to use anti-shake lenses for the first shot, so as not to affect their learning confidence.
