Standard focal length lens introduction

Before I had no time to write a piece of millet drone, was a lot of people Tucao, not the author style of this Zeyang, it is really being edited by the mother's family, not to write ah well, I Write a good one this time to see if you can...

The following is the model of a dog model.

Previously, I saw a small set of standard zoom announcements released by a certain valued friend. As a newcomer to the SLR team for 3 years, he boldly released his own ideas.

When it comes to standard zoom, the first thing to say is its focal length – what is the standard zoom? From Nikon, Canon and the two (in the "civilian level" camera, the Sony lens group is limited, we do not discuss too much, if there is injury, please also include) the official website can be seen, this focal length lens is still a lot of , from the C-family 15-85/3.5-5.6, 18-135/3.5-5.6, 24-105/4 and other lenses (of course, as the standard "standard change" 24-70 F2.8 must be included), According to the 16-85/3.5-5.6, 18-300/3.5-5.6, and 24-120/4 cameras of the N family, the definition of the standard zoom is still relatively broad. It seems that as long as it contains 50 The focal length is basically considered a standard zoom.

The standard zoom is a must-see for every family, so in this focal length, the big three yuan, the small three yuan, emerge one after another. Take only the example of each mirror King, we first mentioned the latest release of the Nikon AF-S NIKKOR 24-70mm f/2.8E ED VR (hereinafter referred to as the new 24-70, relative to the AF-S NIKKOR 24-70mm f / 2.8G ED is old 24-70. This long list of characters seems to indicate something. The first is the AF-S, which is a new Nikon lens. The lens itself has a motor. For some cameras without a motor, auto focus can also be achieved. 24-70mm f/2.8 refers to the focal length and maximum aperture of the lens. Next, the reduction of two aperture aperture imaging has a certain improvement over the maximum aperture, E refers to the built-in electromagnetic aperture, through the lens of the body electronic signal control aperture, and ED refers to the bottom dispersion lens, VR refers to the natural anti-shake function Now.

The following is the proof of the shot. The picture was taken from his own account on other platforms. Therefore, it is not very clear. Let's make it happen.

Before Nikon AF-S Nikkor 24-70mm f/2.8E ED VR is AF-S Nikkor 24-70mm f/2.8G ED (old 24-70), as a N user, I deliberately concerned about this lens There are mixed opinions (in fact, many people say that the new 24-70 is not as good as the old 24-70, but the author thinks that both have advantages and disadvantages - only in terms of performance, not including price). There has never been a formal statement about the comparison between 24 and 70/2.8 of the N generations. As it happens, I have a Nikon D750, and a Nikon AF-S NIKKOR 24-70mm f/2.8E ED VR, I also have a Nikon D750, and a Nikon AF-S Nikkor 24-70mm f/2.8 G ED (The style is a little bit like it's going to go back? Well, really writing). The reason is because after the author bought a D750 himself, a friend who worked with him felt it was easy to use and started to use one. For this reason, the author deliberately conducted some comparative evaluations.

We first talk about the appearance of contrast, the appearance of the new 24-70 than the old 24-70 long section, more obvious on the table, the new 24-70 focal length is marked in front of the zoom ring, in the operation easier Clearly see the focal length specific data.

Since 24-70 is an external zoom (most lenses are internal focus, some lenses are mostly 70-200 are internal zooms, and 24-70 are mostly external zooms), 24-70 have different lens lengths at the longest and widest angles. Both are the longest in the 24-end lens, the shortest when the focal length is 50mm, and 70mm is slightly longer than the 50mm.

From the side view, we can see that the new 24-70 is more than the old 24-70 with a VR switch, which is the anti-shake switch.

It can be seen from the front that the new 24-70 is one to one thicker than the old 24-70. The contrast lens cover is even more obvious.

When observing these two lenses, the outside of the author noticed a detail that is the lens hood, the new lens hood has a very clear logo position, and the bayonet alignment position, but the old models do not. However, the new hood is slightly lower than the old one.

As a two-generation mirror emperor, the new mirror king focus slightly faster than the old mirror emperor, especially in dim conditions or solid color conditions, the old mirror emperor still pull drawer situation appears, but the new mirror emperor can quickly focus - attention It is fast and I can't say exactly. Yes, the new Mirror King focus speed is fast, but its focus accuracy is really worrying, often in the daily use of the situation of focus errors - in the same mode, the old mirror King can accurately focus, so let alone What is wrong with the author's operation? In terms of control of distortion, the new mirror king has an unparalleled advantage, almost no distortion is seen on the 24 side (relative to other 24mm lenses), and the old mirror king can clearly see the distortion. However, in terms of vignetting control, the new mirror emperor is not as good as the old mirror emperor. In the case of full aperture, the vignetting is very special. Particularly, it is noticeable. I have used three special...

In the use of the focus ring and zoom ring, the author found that the new mirror Huang's oil is significantly better than the old mirror king, in fact, the old mirror is the latest purchase of the new king, two lens purchase time difference of less than a month There is no such thing as aging or dust. It should be said that the new lens is really stronger than the old lens.

In terms of price, Nikon's new lens offer is 12,699, and the old lens price is 8,550. Nikon Nichols's club is recommended for purchase by Tianyou photographic equipment. Tiffin has a discount (this advertisement is a bit hard and I hope the editor can give it). As a person, I suggest that users who have purchased Nikon 70-200 to purchase the old mirror king, due to its 77mm aperture filter general, in the ND mirror, gradient, polarized lenses and other aspects, you can consider versatility, if you have not purchased 70 -200 users can directly purchase the new mirror king and wait a little for a while, because there are rumors that the new 70-200 will be on sale soon, do not know if the caliber will become 82mm (this means that the author's wallet once again dried up ...).

The editor said that there is no picture and no truth... then, no connection, no truth, so I went for a gold link and pulled a link. Of course, in order to make more money, anyway, he pulled out the link and he made a favorable offer...


Well, a lot of eloquent, and originally wanted to write a generalized article has also become a comparison of N old and new mirror appearance and trial experience, this article first wrote this, Rongmou home Rest first, chase Ming and then give everyone a different name to change the mirror if I am not lazy.
