In short

The SIGMA ZOOM 28-70mm 1: 2.8 EX ASPHERICAL is an old fast universal lens of the pic era. The camera works well on digital cameras, but it is noticeably inferior in resolution and the number of aberrations to modern lenses. Information technology can exist a upkeep replacement for modern lenses of the 24-seventy / ii.8 class.

There are a huge number of such high-speed universal Sigma zoom lenses, a list of which tin can exist plant at the end of the review.

Sigma 28-70 / ii.eight EX Aspherical attracts with its strong case and low price in the secondary market.

History

Sigma has the largest family unit tree of universal high-aperture zoom lenses. Information technology is sometimes very difficult to distinguish one model from another, every bit well as observe data on a detail modification.

Beneath are listed all such lenses in chronological order of their publication, the names are indicated co-ordinate to the spelling on the lens housing or near the front lens, and the optical design and the number of special elements are indicated:

Assembly

The case pattern resembles the subsequent model SIGMA ZOOM 24-70mm i: 2.eight DG EX ASPHERICAL.

Build quality Sigma 28-70 / 2.8 EX Aspherical is at a high level. The lens is very nice to the touch, well shot down without whatever obvious flaws.Sigma 28-70 / 2.8 EX Aspherical uses a metal mount. The retractable frame of the housing consists of one section. The focus and zoom rings are rubberized.

The lens torso is covered with a characteristic Sigma lens. velvetwhich is typical of many old SIGMA lenses. This blanket may be overwritten, later which the lens does not await so beautiful.

Sigma 28-70 / two.8 EX Aspherical has i characteristic - the trunk of the lens lengthens with a decrease in focal length. Sometimes it's a little annoying, it'south usual that the longer the body of the lens - the more focal length installed, simply it wasn't there. Therefore, it is often joked that such lenses have a focal length range not of '28 -lxx ′, but of '70 -28 ′.

Dissimilar a similar lens Canon '70 -24 ′, the hood is not fixed virtually the fixed role of the frame of the example, but well-nigh the thread nether the filter. Bayonet type hood.

Устройство discontinuity comprises 9 not rounded petals and forms a pigsty in the shape of a regular 9-gon.

Focusing

Motorcar focus speed high (closer to average). Focus speed is contained of photographic camera orientation or focal length.

For focusing, a conventional micro focusing motor is used, which makes a lot of noise. The nature of the noise is unpleasant.

The lens does non apply internal focus. During focusing, the front lens, together with the filter frame, does not rotate, but moves frontward. When changing the focal length, the front lens does not rotate.

The focus ring rotates a trivial less than 90 degrees. The stroke of the ring is smooth.

The minimum focusing distance is xl cm, and the maximum macro ratio is one: 4.3.

When used on a camera Canon EOS Digital Insubordinate XSi (aka Canon EOS DIGITAL 450D, aka Catechism EOS Buss X2 with very unproblematic 9-bespeak focusing system) the lens behaves normally, does not oft make mistakes in focusing. The only problem found was that the lens often did not focus correctly at infinity (it focused much closer). On camera Canon EOS Digital Rebel XSi I checked the presence of the dorsum and focus forepart at dissimilar focusing distances (infinity and MDF likewise). Pictures taken using the Live View manner (which does non endure from back / front focus) were used every bit a measure. Focusing accurateness using phase sensors completely coincided with the Live View mode.

Focus Features:

  1. Sigma 28-70 / ii.viii EX Aspherical has focus style switch 'AF-M'. To perform transmission focus lens required must be in focus mode 'M'. Sigma 28-70 / 2.viii EX Aspherical does not have the function of continuous transmission focus control.
  2. During auto focus focus band rotates and cannot be touched.
  3. There is the effect of 'Focus Animate' (changes in viewing angle during focusing). During focusing towards MDF, the viewing angle increases.
  4. Sigma 28-lxx / ii.8 EX Aspherical is a tertiary-party lens. It may happen that it will non piece of work correctly with some Catechism EOS cameras.
  5. When irresolute the focal length, focusing is a bit confused.
  6. The lens has scale with focusing distance in meters and feet. Such a scale in itself is of little employ and is present more for bear witness (justification of this thought here) The distance scale is plotted on the focus ring, and not made using a special window.
  7. Unknown compatibility with teleconverters.
  8. Sigma 28-70 / 2.8 EX Aspherical does non accept hard cease (hard infinity mechanical stop) which allows you lot to accurately and quickly focus the lens at infinity nether any external weather.
  9. Focus shift (shift-focus) is missing.

Prototype quality and sample photos

I used a Sigma 28-70 / 2.8 EX Aspherical lens with a Canon EOS DIGITAL Rebel XSi crop photographic camera (aka Catechism EOS DIGITAL 450D, aka Canon EOS Buss X2), because I can not judge some of the features of this lens in full, in the first place it is non clear what epitome quality at the edges and corners of the frame when using information technology on total-format cameras.

The lens is rather mediocre at F / ii.8 in the eye of the frame over the entire range of focal lengths, while the lens is non then bad as to completely carelessness the employ of F / 2.8. The moving-picture show suffers from chromatic aberration. Distortion acceptable for a lens of this grade. Vignetting on APS-C cameras is slightly noticeable fifty-fifty on F / ii.viii.

Optimum image quality is accomplished at F / v.6-F / 11 and medium focusing distances.

My experience

Sigma 28-seventy / 2.8 EX Aspherical is old and not very noticeable. If you lot are looking for a balanced budget model that can be a replacement for a 24-70 / 2.8 class lens, let'southward look at Tamron SP AF Aspherical XR Di LD [IF] 28-75mm 1: 2.viii Macro A09.

SIGMA ZOOM 28-70mm i: 2.8 EX ASPHERICAL

UPDATE, version for Nikon

Came to me to review a copy of the Sigma 28-70 / 2.viii EX Aspherical for Nikon cameras. Information technology looks like this:

  • Unlike the version for Catechism, the version for Nikon no focus mode switch... To catechumen the lens to manual focus on cameras with motor For focusing, use the focus mode switching lever located near the camera mount. For cameras without motor Simply manual focus mode volition ever be bachelor for focusing.
  • Motorcar focus with this lens is available.but when using it on cameras with a built-in focus motor. The exact listing of such cameras can be viewed here... During focusing, the focus ring rotates and should not be touched.
  • The lens has transmission aperture ring. To be able to control the value aperture from camera or for automated installation aperture on modern central command valves, you need to turn the control ring to the extreme position and fix it with a special switch, which is located on the right. If this is not done, so on a number of cameras, the brandish will display an mistake - 'fEE' (band is not installed aperture) Some cameras having diaphragm rheostatallow you to control the aperture using the band aperturebut only in metering modes exposure '1000' and 'A'. You lot tin read more virtually this issue in the section on Non-G Lenses. Ring aperture rotates with clicks.
  • I shot at him and Nikon D700 I have hither

Results

Sigma 28-70 / two.8 EX Aspherical - an sometime man, can be a proficient solution for enthusiastic amateur photographers.

Advantages

  1. fast focus
  2. during focusing, the front end lens and the thread under the filters do not rotate
  3. good maximum magnification ratio for macro shooting, which is 1: 4.two
  4. focus distance calibration, depth of field and tag for working in the infrared spectrum
  5. skillful build quality, sturdy structure, metal mount, rubberized focus and zoom rings, the lens does not alter focal length under its own weight, bayonet type hood. Considered a professional Sigma EX lens
  6. 9 petals aperture, the lens creates fairly smoothen blur discs
  7. F / two.8 over the entire range of focal lengths, a very convenient set of focal lengths
  8. aspherical elements in the optical scheme
  9. normal sharpness in the centre of the frame on covered apertures
  10. weak vignetting on Catechism cameras with APS-C sensor (crop)
  11. acceptable distortion
  12. lack of focus-shift during iris

The main disadvantages

  1. ordinary micro focusing motor instead of an ultrasonic motor (or similar), which use original lenses
  2. unpleasant racket during auto focus
  3. rotation of the focus ring during autofocus and, equally a result, lack of the function of constant manual focus control
  4. small focus ring travel
  5. while zooming and / or focusing, the trunk moves forward
  6. focusing falters while irresolute the focal length
  7. the zoom ring rotates in the opposite management (inconvenience for those who have original Canon zoom lenses)
  8. rear lens motion while changing the focal length, small consequence of a vacuum cleaner / air pump
  9. 'Focus Breathing' effect (irresolute the viewing angle during focusing)
  10. the lack of a protective O-ring near the mount and the absence of whatsoever dust and moisture protection, which is critical for a professional person lens
  11. outdated model non optimized for use with modern digital cameras (optimization only starting from Sigma 28-70 DG model)
  12. poor image quality: poor resolution on open apertures, strong chromatic aberrationlow backlight resistance
  13. slight seedling bokeh effect
  14. there may exist incompatibility with some cameras and / or teleconverters (no exact information)
  15. lack of information about the lens in modern cameras, which makes it hard to automatically correct some types of distortion (baloney, vignetting etc.)
