According provided by lens Sigma 70-200mm 1: 2.8 APO EX HSM (for Canon) many thanks to Oleg Malakhov.
The Sigma 70-200mm 1: 2.8 APO EX HSM is a classic, professional, fast telephoto lens. Available for different mounts for SLR cameras, this review presents a version for Canon EOS cameras.
Please note that there are several similar lenses:
- Sigma 70-200mm 1: 2.8 APO EX HSM is the oldest version presented in this review.
- Sigma 70-200mm 1: 2.8 APO DG EX HSM is an updated model with the same optical design, optimized for use on digital SLR cameras. The main difference is improved enlightenment.
- Sigma 70-200mm 1: 2.8 Macro APO DG EX HSM is a new model with a different optical design, produced since 2008. The main difference is a different MDF and more weight.
- Sigma 70-200mm 1: 2.8 II Macro APO DG EX HSM is an updated previous model.
- Sigma 70-200mm 1: 2.8 APO DG EX HSM Optical Stabilizer, released in 2010, has a built-in image stabilizer. Overview can be viewed here.
Also, there are two models of class 70-210 / 2.8:
- Sigma AF Zoom APO 70-210mm 1: 2.8, filter diameter 82 mm
- Sigma AF Zoom APO 70-210mm 1: 2.8filter diameter 77 mm
Sigma 70-200mm 1: 2.8 APO EX HSM - well made, focus and zoom rings are rubberized. Weighs almost 1300 grams. Due to its large dimensions and heavy weight, there is a tripod foot on the lens barrel, which rotates 360 degrees around its axis and is fixed with a screw clamp. The clamp has two marks by which it is easy to determine its condition. To remove the foot, pull on the clamp. Also, on the body, you can find two white stripes, which, when compared with the white strip of the clamp on the tripod foot, make it possible to quickly rotate the lens to a landscape or portrait position.
The lens has already become a classic lens mount, which can be installed both in the normal position (to get rid of glare and flare), and in the opposite position (for transportation), although access to the focus ring is completely lost.
On the body there is a scale for focusing distance in meters and feet, an 'R' mark for shooting in the IR spectrum for 70 mm and a depth of field scale for the wide-angle range (denoted on the body with the letter 'w' for F / 11, 16, 22) and for the tele range (marked on the body with the letter 't' only for F / 22). There is a small focus mode switch 'AF / M', which is located near the mount. MDF is 1.8 meters (maximum magnification ratio for macro is 1: 7.8). The zoom and focusing of the lens is internal - when the focal length is changed, as well as when focusing, nothing moves and does not rotate (including the rear lens).
The autofocus speed is above average, but I can't call it fast enough. I noticed that with different orientation of the lens in space and at different focal lengths, the autofocus speed changes noticeably. This is most likely due to the different force that needs to be applied to move the objective lens during focusing. On other lenses, I did not notice such an obvious spread of speed depending on the orientation of the camera.
The focus ring rotates approximately 120 degrees, it is very wide and easy to use. It's a pity, but the lens does not have full-time permanent manual focus control (the so-called FTM mode — Full Time Manual Focusing). FTM is only available with 'One shot' and 'AI Focus' focusing method. In 'Ai Servo' focus mode, a 'focus control fight' ensues between me and the lens.
Diaphragm consists of 9 petals, closes over the entire range of focal lengths to F / 32. The lens uses light filters with a diameter of 77 mm.
This Sigma telephoto is pleasantly pleased with the image quality. Well fixed chromatic aberration, at f / 2.8 it’s quite normal sharpness. At 200 mm and F / 2.8 there is a slight drop in sharpness, but closing the aperture to F / 4, we get a very nice picture. The lens is a little afraid of flare, it is best to shoot with a hood. Bokeh is very nice :)
On Canon APS-C cameras, the EGF of the lens is 112-320 mm, on such cameras the lens vignetting is almost zero.

In the comments, you can ask a question on the topic and they will answer you, as well as you can express your opinion or describe your experience. For the selection of photographic equipment, I recommend large catalogs, for example E-Catalog. Many little things for the photo can be found on AliExpress.
Sigma 70-200mm 1: 2.8 APO EX HSM is a good lens, worthy replacement for 'native lenses' of class 70 (80) -200 / 2.8.
