On subframe cameras, 21 mm of focal length is assigned to the ultra-wide-angle range of focal lengths.

Unfortunately, despite the presence of a microprocessor, the Carl Zeiss Distagon 2.8 / 21 T * ZF.2 version does not work in the focus trap mode (when the shutter is only allowed with precise focus). Only a green dot in the viewfinder indicates sharp focus. It is advisable to use the Live View mode with the lens. On the camera, the lens is recognized as autofocus, but switched to manual focus mode.

The iris automation on the manual lens significantly adds convenience in work and post-processing (you can always see with what settings the photo was taken).

It's important: Carl Zeiss Distagon 2.8 / 21 T * ZF.2 on cameras Nikon D3400, D3500 can only work in 'M' mode. These cameras simply do not support NON-G type lenses (which have an aperture control ring). On all other cameras, the Carl Zeiss Distagon 2.8 / 21 T * ZF.2 will work like any other original lens on which autofocus is disabled. All camera modes will be available.

Assembly and management

The lens is made very high quality. The body has a significant thickening near the front lens. The body is made of metal, the focus ring and aperture are also metal, not rubberized.

The Carl Zeiss Distagon 2.8 / 21 T * ZF.2 comes with a durable metal bayonet-type hood. On the inside, the hood has special coating, reminiscent of velvet, which adds a sense of premium things. The hood can be installed in the reverse position for transportation. In this position, access to the focus ring is a little difficult.

The diameter of the filter is as much as 82 mm.

Carl Zeiss Distagon 2.8 / 21 T * ZF.2 has a manual aperture ring. To be able to control the value aperture from camera or for automatic installation aperture on modern digital cameras, you need to turn the control ring to the value F / 22, after which it is automatically fixed by a small special button-lock, which is located to the left of the marks aperture. If this is not done, then the display will show 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, the values ​​F / 2.8, 4, 5.6, 8, 11, 16, 22 (full stops) are plotted on it; You can set one intermediate value between pairs of numbers (except between F / 16 and F / 22). Other intermediate values ​​can only be set via the camera itself.

Focusing

Carl Zeiss Distagon 2.8 / 21 T * ZF.2 may use manual focus only.

The focus ring is wide enough. The ring rotates on 120 degrees. The focus is smooth and pleasant one of the best I've ever tried. When extreme positions are reached, the focus ring abuts and cannot be rotated further, while a characteristic metallic sonorous knock is heard. The direction of rotation of the focus ring matches Nikon's original lenses, such as Nikon 20 / 1.8G.

The focus ring is poorly 'stretched' in the range from a meter to infinity, which is why it is not always convenient to focus in this range of distances.

Used floating focus, something like the original Nikon CRC technology (for example, as in the manual Nikon Nikkor 35mm 1: 1.4 AI-S) This technology is designed to receive high-quality images at all focusing distances.

Carl Zeiss Distagon 2.8 / 21 T * ZF.2 uses ininternal focus, to be more precise - focusing using the rear lens group. The front lens and the filter thread do not rotate during focusing.

On the focus ring there is a scale with the focusing distance in meters and feet, there is also a depth of field scale and a mark for working in the infrared spectrum.

The minimum focusing distance is 22 cm (the distance from the camera’s sensor to the subject). With such an MDF, the maximum magnification ratio is 1: 5.

There is a very small effect of 'Focus Breathing' (changing the viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases.

Focus Shift (shift focus, changing the focus distance due to iris) is missing.

The Carl Zeiss Distagon 2.8 / 21 T * ZF.2 has a hard stop (hard infinity mechanical stop) for quick and accurate aiming at infinity under any temperature operating conditions.

When used on cameras Nikon D3200, D40, D700, D5600, D7200 the green dot, confirming the correct focusing, works correctly.

Important: despite the fact that the lens has microprocessor contacts, it does not transmit the distance to the subject into the camera and is an analog of NON-D lenses. This can sometimes affect accurate metering. exposure, especially when using flash.

Image quality

Carl Zeiss Distagon 2.8 / 21 T * ZF.2 creates a very high-quality picture. But, of course, there are several minor flaws.

Sharpness

  • very high sharpness in the center of the frame is already at f / 2.8
  • slight drop in resolution at the corners of the image
  • sharpness slightly increases with aperture closing

Distortion

  • there is a slight pincushion distortion
  • the nature of distortion is complex, it’s difficult to correct in editors

Vignetting

  • at f / 2.8 vignetting is in the area of ​​2 steps
  • vignetting almost disappears at values ​​after f / 5.6
  • vignetting is easily fixable in the editor

Aberration

  • low chromatic aberration

Other

  • the lens tolerates lateral and backlight not bad, but still quite often you can get a reddish or greenish glare from hard backlight
  • aperture blades form a regular octagon on any hidden aperture values
  • on closed diaphragms you can get the effect of an 18-ray star

My experience

Many different photographers and amateur photographers have already told me more than once about the 'best' of the shirikov - Carl Zeiss Distagon 2.8 / 21 T * ZF.2 (in fact, it doesn't matter which version of it: C / Y, ZF, ZF. 2, ZE, ZK or Milvus).

With the Carl Zeiss Distagon 2.8 / 21 T * ZF.2 everything is very simple - this is a really very good lens, indeed one of the best wide lenses available. But this does not mean that he is the best and does not mean that he is balanced.

Optically Milvus 2.8/21 ZF.2 Zeiss Distagon 2.8 / 21 T * and Carl Zeiss Distagon 2.8 / 21 T * ZF.2 are almost identical. The same is confirmed by MTF charts for these lenses.

I have used the Carl Zeiss Distagon 2.8 / 21 T * ZF.2 for almost a month, I shot a lot with it, I only have a very good opinion about it. Now I will be like its other owners - I will praise it in every possible way and tell their legends around the wonderful Carl Zeiss Distagon 2.8 / 21 T * ZF.2... One of the legends is that at F / 2.8 it is no worse than at F / 5.6.

Results

The Carl Zeiss Distagon 2.8 / 21 T * ZF.2 is a very high quality ultra wide-angle lens, both in terms of build and image quality. In 2015 it was replaced by a similar one Milvus 2.8 / 21 ZF.2 Zeiss Distagon 2.8 / 21 T * based on the same optical design and practically the same image quality (MFT graphics confirm this). It is considered one of the best such lenses of all time.

10 main advantages:

  1. full metal case
  2. metal hood included
  3. unusual design with a wide front of the case
  4. internal focusing (using the rear lens group)
  5. floating focus system, provides high image quality at all focusing distances
  6. nine aperture blades
  7. all the necessary tags are present: focusing distance, depth of field, infrared spectrum tag
  8. T * enlightenment, which makes the lens glare-resistant and provides good color reproduction
  9. microprocessor contacts for correct operation with EXIF and for convenient work with the lens
  10. good optical performance, high resolution in the center of the frame already with F / 2.8, good resolution in the corners of the frame (which is very important for an ultra-wide-angle lens), low distortion

10 main disadvantages:

  1. high cost (more expensive than autofocus and brighter Sigma 20 / 1.4 Art, Nikon 20 / 1.8G)
  2. large front filter diameter 82 mm
  3. lenses from other third-party manufacturers can offer much more functionality: auto focus, image stabilizer or higher aperture
  4. focus ring poorly 'stretched' from infinity
  5. no way to customize focus trap (when shutter release is possible only when accurate focus is achieved)
  6. quite a lot of weight (600 grams with a hood and a front cover)
  7. the lens does not transmit the focus distance to the camera (Non-d lens type, important for accurate metering exposure)
  8. non-protected lens (security appeared in the version Milvus 2.8 / 21 ZF.2 Zeiss Distagon 2.8 / 21 T *)
  9. palpable vignetting at f / 2.8. Although very low, but complex distortion
  10. backlight glare

  • Oleg

    Good but overrated

  • Pavel Gorbunov

    Zeiss all overrated))

    • Maksim

      Normal price for a good lens. Who is to blame for the ruble falling?

  • Yuriy75

    For that kind of money, he still has to clean and eat to cook in the apartment

    • Jurassic

      Hahaha ... and that's just a minimum extra. services ...)))

  • Vadim fedorov

    Thank you. Interesting.

  • Boris

    I shoot on a similar Nikonovsky 20 1.8G. Zeiss has a better look at the farthest angles on open diaphragms. After 5.6, the sharpness is similar, but in the picture there may be differences

  • koba

    I can contribute - I personally tested it for myself, and now I am saving money. In excellent condition, you can sometimes find it for 700-750 dollars. In real work, it's just a miracle, of course, at apertures of 5,6, in fact, in most cases, we work, but if necessary, you can use it at F4, or even at F2.8. The marking of the distance scale up to 2 meters with such a focal length makes it possible to work blindly at aperture 5,6, that is, a zone focus.

  • Eugen

    I have long wanted this, but I bought Vogtlender 1.8 / 21 first, and recently I was very lucky to get Loxia 2.8 / 21. Now, if you change them to a mirror analogue, then only in the Milvus version.

  • Nicholas

    Great lens.
    I sell in excellent condition (boxed version) as unnecessary at a good price.
