What is the equivalent focal length of the Nikon lens AF S DX 18 105 f 3 5 5 6G ED VR?

First of all, you must understand that in DX format, the focal length of the lens remains the same, and the angle of view is different!

Pay attention to the above sentence.

For example, a 24-70 lens with a focal length of 24-70 on an FX machine would still have a focal length of 24-70 on a DX machine! What changes is the angle of view rather than the focal length, which is equivalent to the angle of view at the focal length of 36-105mm in full-frame format.

This is due to the difference in the angle of view caused by the size of the sensor, and the value obtained by the conversion factor is only the focal length with the same angle of view in full-frame mode, and it is easy to understand that everyone says "equivalent focal length". This has nothing to do with the lens itself (of course, we don't remember whether the lens is in full-frame format or not).

The 18-105 lens is in DX format, meaning that it is only available in DX mode. The focal length is still 18-105, and the angle of view is equivalent to the full-frame perspective. Got it?

It's not like the first floor said, there is no problem with the FX body. Nikon kindly said that the FX body can be converted to DX format, but if it is like Canon, is it still possible to use it? In Nikon's machine, the FX body is connected to the 18-105 DX head, which needs to be converted to DX format, with the focal length still 18-105 and the angle of view being DX.

That's all I can say, and the specifics are all available.

The above is also an explanation as to why full-frame is more advantageous and why C-frame earns telephoto is a pure fallacy.

Converting the focal length is to look at the body rather than the lens. This coefficient is due to the fact that the CCD area of the DX format is smaller than that of the full frame. If the head is attached to the fx frame, there will be no problem, and of course no one will.

The annotations on the lens are all parameters of the lens itself, so keep that in mind

So 18-105 needs to be multiplied.

Equivalent to around 27-150.

First, the lens structure is different.

1. Nikon AF-S Nikkor 24-120mm F 4G ED VR: 17 elements in 13 groups.

2. Nikon AF-S VR 24-120mm F IF-ED: The lens structure is 15 elements in 13 groups.

Second, the focusing distance is different.

1. Nikon AF-S Nikkor 24-120mm F 4G ED VR: The minimum focusing distance is.

2. Nikon AF-S VR 24-120mm F IF-ED: Minimum focusing distance.

3. Different optical parameters.

1. Nikon AF-S Nikkor 24-120mm F 4G ED VR: maximum aperture, minimum aperture F22.

2. Nikon AF-S VR 24-120mm F IF-ED: Maximum aperture: , Minimum aperture: F22-F32.

2. Nikon AF-S VR 24-120mm F IF-ED: Maximum aperture: , Minimum aperture: F22-F32.

The main difference between these two lenses is the aperture, the old 24-120 is a non-constant aperture and a relatively cheap full-frame lens, the image stabilization is still a generation, the new 24-120 is a constant 4 aperture, and the second generation of image stabilization, or the gold circle lens, in Nikon, the relative workmanship and materials of the gold circle lens are still very good, the most important thing is the difference in image quality, the image quality of the second generation of the new head is much better than the first generation, and Canon 24-105 is a grade lens, But it's more expensive than that.

The lens structure is different, and they are two completely different heads. It is said that the picture quality and resolution have improved a lot. I think the original VR version is good.

The latter filter is larger in size and has a higher number of lenses than the former, while the latter lens is coated with nanocrystalline to greatly reduce ghosting and glare.

Can the Nikon AF-S VR 70-300mm F IF-ED be fitted with a leakage talgoggle? Some people say that Kengao can be returned, right?

Hello, dear <>

We are happy to answer the question: Can the Nikon AF-S VR 70-300mm F IF-ed be equipped with a telescope? Some people say Kengaw can, right?

Answer: Kiss, yes, but you can't autofocus, you have to choose a teleconverter that matches it, and if you don't match, the autofocus and aperture adjustment functions will be gone. However, teleconverters are not recommended. Teleconverters also reduce the aperture value by one or half stops.

At that point, the viewfinder will be very dark, which will affect the focus and shutter speed.

Summary. Can the Nikon AF-S VR 70-300mm F IF-ed be fitted with a teleconverter? Some people say Kengaw can, right? Hello dear, <>

Yes, yes buy Kengo, Kengo 2x teleconverter, there are also 70 300vr installed no problem, but it can't autofocus. When the shutter is pressed halfway, the lens will constantly pull the bellows to focus repeatedly, and it cannot be aligned. Hope it helps!

Yes, yes buy Kengo, Kengo 2x teleconverter, there are also 70 300vr installed no problem, but it can't autofocus. When the shutter is lifted half-pressed, the lens will continue to pull the bellows to focus repeatedly, and the lead mold cannot be aligned. Hope it helps!

Can the Nikon AF-S VR 70-300mm F IF-ed be shipped with a teleconverter? Some people say Kengaw can, right? Hello dear, <>

The Nikon AF-S VR 70-300mm F can be used with the Kengao MC4 AF DGX Teleconverter, but due to the limitation of the lens aperture, it can only be used with the manual focus function, which requires special attention from the landlord, and can be considered if it is acceptable. "I hope Huixun can help you!

18-105 is the actual focal length of the lens itself. If this lens is used on the body of the DX, then the focal length coefficient still needs to be multiplied.

The standard focal length you mentioned, I want to explain, this has nothing to do with the focal length of the lens or anything. This refers to the focal length closest to the angle of view of the human eye, which is about 50mm, and most manufacturers currently have fixed focal length lens products with a focal length of about 50mm (such as 50mm of each factory, this type of lens is called "standard lens" (referred to as the head), and this focal length is also the standard focal length (of course, this is the real sense of the header on the FX format camera, and DX due to the existence of a conversion factor, so its header focal length should be about 35mm, such as Nikon's 35).

Therefore, whether the focal length coefficient of the lens used needs to be multiplied or not, it only depends on whether the body you are using is in DX format or FX format, and it has nothing to do with the data written on the lens body. The actual physical focal length of the lens is engraved on the lens body.

To add... As mentioned upstairs, with a DX format camera, the equivalent focal length becomes longer, which is actually equivalent to cutting off a part from the **center of the FX format camera, and then expanding this part to the same size as the actual FX** for comparison, so it seems that the DX format has a telephoto advantage and can be placed larger. In fact, the size of the sensor is very objective, and it cannot change the disadvantage of DX in the actual frame.

Neither of the two upstairs was correct enough.

See clearly: Nikon AF-S DX VR 18-105mm F ED; This lens has the word DX, which is a "DX format" lens designed for the DX frame body, mounted on the DX body, and the focal length is equivalent to 1:1, not 1:

Target. DX lenses have a small image field and cannot be used on full-frame (FX) bodies; Conversely, full-frame (FX) lenses can be used on DX bodies, but with a multiplier factor.

There are a few things to pay attention to when looking at the camera:

The lens has a DX logo, which means that this lens is only suitable for the DX body, which is the body of the APS-C format, and this lens is on the APS-C format with the same focal length.

The lens has an FX designation, indicating that the lens is a digital full-frame lens.

There are no above two words on the lens, indicating that the lens is the original 135 film SLR camera lens, which is equivalent to 1:1 in the digital full-frame body; On the aps format, the equivalent focal length is 1:.

The actual focal length, of course.

The concept of standard focal length ......I don't know. Everyone is accustomed to using the 135 system equivalent focal length.

The equivalent focal length cannot be written on the lens, and it is a fraud to write it. After all, the equivalent focal length is just a conversion written for ease of understanding, and does not have the meaning of a ruler.

The 18-105 equivalent focal length is a very good focal length for daily use.

This lens focal length is the actual focal length, and the standard focal length is a factor of 135 systems, and this head is a DX head.
