In short

The Tokina AT-X 270 AF PRO is an old professional, fast, versatile lens for full-frame film cameras. Legendary model from Tokina. Excellent build quality, but many features with image quality.

At one time, the Tokina AT-X 270 AF PRO was one of the fastest universal photo lenses. Its marking indicates 1: 2.6-2.8, which theoretically allows the use of a relative aperture of 1: 2.6 per 28 mm of focal length. Such aperture he inherited from his ancestor - the legendary Angenieux Zoom F.28-70 1:2.6 AF... However, with the Tokina AT-X 270 AF PRO, not everything is so rosy:

  1. F / 2.6 only available at 28 mm focal length
  2. F / 2.6 is just 1.16 times lighter than the classic F / 2.8 value. Is it worth chasing 16% (1/6 stop) aperture in the wide-angle range?
  3. in terms of real apertureexpressed in T-stops, there is practically no gain
  4. on most modern cameras, the menu will show F / 2.8 instead of F / 2.6. The standard F-numbers for modern cameras are F / 2.5 and F / 2.8 (no space between them)
  5. the same lens was produced for Japan with marking Tokina AT-X PRO AF 28-70mm 1: 2.8 (the same Tokina AT-X 270 AF PRO model), while users may not have guessed that F / 2.6 is actually used instead of F / 2.8

History

Tokina AT-X 270 AF PRO was produced since 1994.

There are a fairly large number of such lenses from Tokina. The difficulty in identifying a particular instance is due to the fact that some of them are very similar in appearance, and lenses were marked differently for different countries. For some lenses (depending on the target country), the maximum aperture F / 2.6 for 28 mm focal length.

The evolution of Tokina Class 24 (28) -70 (80) /2.8 (2.6-2.8) lenses:

  1. Tokina AT-X AF 28-70mm 1: 2.8 - orange border near the front lens, filter diameter 72 mm, focusing is not internal. Window focusing distances. The name on the box is Tokina AT-X 270 AF.
  2. Tokina AT-X PRO AF 28-70mm 1: 2.6-2.8 (1: 2.8) - marking '1: 2.8' for Japan, marking '1: 2.6-2.8' for other countries, filter diameter 77 mm, internal focusing. The hood is threaded. Without a window of focusing distances, a gold border near the front lens. The name on the box is Tokina AT-X 270 AF PRO. You can distinguish on these signs of.
  3. Tokina AT-X PRO 28-70mm 1: 2.6-2.8 (1: 2.8) - marking '1: 2.8' for Japan, marking '1: 2.6-2.8' for other countries, filter diameter 77 mm. Externally similar to the previous version, but there is no 'Tokina' lettering near the front lens, and the hood is bayonet type. The version is commonly referred to as 'AT-X PRO II'. Name on the box Tokina AT-X 270 AF PRO II. You can distinguish on these signs of.
  4. Tokina AT-X PRO 28-80 1: 2.8 Aspherical - a window of a focus scale, a gold border near the front lens. The name on the box is Tokina AT-X 280 AF PRO. There is a subversion with a gold nameplate with the name of the lens and other enlightenment.
  5. Tokina AT-X PRO SV 28-70mm 1: 2.8 (also called Tokina AT-X 287 PRO SV) - easily recognized by the 'PRO SV' prefix. Name on the box Tokina AT-X 287 AF PRO SV.
  6. Tokina SD 24-70 F2.8 (IF) FX AT-X PRO Aspherical - easy to find by focal lengths. Has a built-in focus motor. Name on the box Tokina AT-X 24 ~ 70mm F2.8 PRO FX

As indicated above, the versions of Tokina AT-X 270 AF PRO and Tokina AT-X 270 AF PRO II exist in two versions: '1: 2.8' and '1: 2.6-2.8' and are quite similar to each other. The easiest way to distinguish between 'PRO' and 'PRO II' is by the inscription 'TOKINA' near the front lens and the presence of fasteners for the bayonet hood:

Assembly / management

Tokina AT-X 270 AF PRO has a very high quality build. The mount is made of chrome-plated brass. The inner frame is made of duralumin. The remaining parts are made of durable composite materials. Many users are very attracted by the pleasant tactile sensation when working with similar Tokina lenses. True to the touch Tokina AT-X 280AF PRO performed even better.

During a change in focal length, the front lens moves in a wave-like fashion, but does not extend further than the front of the barrel, and therefore does not increase the overall dimensions of the lens. The maximum lens recess is available at 50-70 mm focal length and focusing at infinity (the effect of the built-in lens hood is obtained). The front lens is moved as close as possible to the edge of the body frame by 28 mm focal length and focusing on MDF. We can say that the lens has internal focusing and internal zoom and does not change its size. When changing the focal length, the rear lens moves, the effect of a vacuum cleaner is minimal.

Unlike the Tokina AT-X 270 AF PRO, the original Nikon / Canon class 24 (28) -70 / 2.8 lenses have a movable front frame (trunk), which does not look as stylish as the internal zoom of the Tokina AT-X 270 AF PRO

The lens has a manual aperture ring. To be able to control the value aperture from camera or for automatic installation aperture on modern central control valves, you need to turn the control ring to F / 22 and fix it with a special switch, which is located to the right of the marks aperture. The F / 22 value and the latch mark are highlighted in green to match them. If this is not done, then on a number of cameras, the display will display an error - 'fEE' (ring is not installed aperture) Some cameras having diaphragm rheostatallow you to control the aperture using the ring aperturebut only in metering modes exposure 'M' and 'A'. You can read more about this issue in the section on Non-G Lenses. Ring aperture rotates with clicks, F /2.6, 4, 5.6, 8, 11, 16, 22. Intermediate values ​​can only be set using the camera menu.

The diaphragm consists of 8 straight lobes and forms regular 8-gons (sample photo on f / 5).

Focusing

Auto focus is fast enough. During focusing, the front lens rotates and moves in the middle of the frame of the body (we can arbitrarily assume that the lens has internal focusing). In manual focus mode, the focus ring rotates 70 degrees. During auto focus, the focus ring can rotate freely between the extreme positions without affecting the focus. It is convenient to support the lens behind the focus ring.

There is a special Tokyo-based AF / MF One-touch focus clutch switch (one-touch focus mode switch). To switch between focus modes, just pull the focus ring toward the bayonet mount or front lens. The switch is uncomfortable. It will be possible to switch from automatic focus mode to manual only in the position of the focus ring in which the reverse transition was carried out. But you can switch from manual to automatic mode in any position of the ring (at any set focusing distance).

It's important: auto focus with this lens is available only when using him on cameras with built-in motor focusing.

Only auto focus and sound confirmation of focus will not work with these cameras, all other important functions, such as automatic exposure metering and automatic iris control, will work well.

You will find a lot of useful information on the types of cameras and lenses Nikon here.

Focus Features:

  1.  Focus speed may vary slightly from the camera used. This issue has been considered. here.
  2. During focusing, the lens and camera are quite noisy. The noise level can be found in my video review of this lens.
  3. There is a small effect of 'Focus Breathing' (changing the viewing angle during focusing).
  4. Tokina AT-X 270 AF PRO is a third party lens. It may happen that it will not work correctly with some Nikon cameras. Details on this issue have been reviewed by me here.
  5. When changing the focal length, focusing is a bit confused.
  6. Tokina AT-X 270 AF PRO transmits the focus distance to the subject in the camera and is a type lens Nikon D.
  7. The lens has a scale with a focusing distance in meters and feet, as well as a mark scale for working in the infrared spectrum.
  8. I got a review with a lens with problems of adhesion with the focusing motor of the camera, as well as with a problem ring of the diaphragm, so I can not judge the accuracy, tenacity of focus.

My experience

Tokina AT-X 270 AF PRO is a pleasant lens to work with, but for those looking for an inexpensive omnivorous all-rounder for a wide range of tasks, I would recommend finding a good copy. Tamron SP AF Aspherical XR Di LD [IF] 28-75mm 1: 2.8 Macro A09. Many times I met photographers who were unhappy with the image quality from similar Tokina lenses. Some argued that there was some kind of disease in the optics of these models, which over time manifests itself in the alignment of lenses and the deterioration of image quality. You can write your thoughts on this in the comments on this review.

  • Alexander

    Hello Arkady. You were right about the lever on the mount, the diaphragm ring pressed a little harder and voila, it worked, thanks for the help!

  • Paul

    There is this lens in everyday life. Someone scolds him, and someone praises him. I will say that this versatile horse is simply gorgeous for its money. And its price allows you to forget about small errors and autofocus noise. Who has money - buy a native from Nikon. I read somewhere that they are not recommended to shoot weddings ... well, I don’t even know, everything is fine, if you do not take into account autofocus misses and misses in non-contrasting scenes in dark rooms. I tried the older 24-70, the only thing I can say is that the autofocus has become a little faster, and the picture is just as beautiful.

    It's strange to hear this about this lens. Years 10t.n. interested in this focal length and aperture ratio. So, the general opinion was that among the Sigma and Tokin 28-70 / 2.8 it is the specimen with the aperture of 2.6-2,8 on the open aperture that does not have a soft effect. Only the Sigma 24-60 / 2.8 can compete with it, but this is a slightly different lens. Maybe we are talking about a lens with the designation PRO ll ?. You see, in spite of the allegedly identical optical scheme, it doesn't matter that something is changed there, otherwise what's the point of releasing another lens by changing it outwardly, let's say the inscription.
    This 2.6-2.8 lens on ebay has always cost more than just 2.8 and it was much less common. Due to its rarity, it is difficult to judge the differences, because there are significantly fewer users who could compare it with the one.

      “You see, despite the supposedly identical optical design, it’s all the same that something has been changed there, otherwise what’s the point of releasing another lens changing it only outwardly, let’s say the inscription ... Because of its rarity, it’s difficult to judge the differences, because users who could use it much less to compare with this and that.”

      I read it five times, but I did not comprehend the deep meaning of the phrase.

    I only recently purchased this lens for 17 thousand, although I thought about it three years ago. I have a version, as I understand it, AT-X PRO II. There really is software (it already disappears at f4), the sharpness is very good even at open, at 5.6 my 12 MP is not enough to realize the full potential of the lens. Of the minuses - it is very difficult to find the original lens hood, the lens itself is incredibly heavy. There is also a problem that the zoom rotates with an uneven effort - in the region of up to about 50mm it is quite heavy, and then something inside seems to let go and it starts to scroll easier. If you hold the lens vertically, there is no such problem. Apparently, over time, the guides inside were worn out ...

      Everything is as you wrote: at 4.0 the software is not visible, the sharpness is enough for a 16MP matrix in full frame. There is a problem with lens hoods - they are put somewhere, and it is difficult to find it for 28-70 and 28-80. Compared to the 28-80, the 28-70 is lighter and feels more compact in the hand.
      The guides are also correct. I had something like this under Canon. I tried 2 copies, gave it for repair and then sold it, and bought myself a fresher one in a better condition. Under Nikon, there is also one, in good condition. The lens is nice.
