![]() ![]() FLD - ( Fluorite-like Low Dispersion) - special low-disperse elements in the optical scheme with characteristics close to fluorite.SLD ( Special Low Dispersion) - special low dispersion elements in the optical scheme.aspherical ( ASP) - the presence of aspherical elements in the optical scheme.IF ( Iinternal Focusing) - internal focus.Df ( Dual Focus) - a focusing system for convenient work with the focusing ring (DF is written near the front lens, or on the box / instruction).DN - lens designed for mirrorless digital cameras.DG - the lens is designed for full-frame SLR digital cameras.EX ( EXcellent) - the highest quality professional lens.Sigma 20-40mm Zoom 1: 2.8 EX DG aspherical IF, 17/13, since August 2001.Separately, you can still identify almost universal: Sigma 24-60mm 1: 2.8 Zoom EX DG, 16/15, several subversions, since May 2004.Sigma 24-70mm 1: 2.8 Zoom EX DG aspherical, 14/13, since February 2001.Sigma 28-70mm 1: 2.8 Zoom EX aspherical DF, 15/12, since February 2001.It is sometimes very difficult to distinguish one model from another, as well as find information on a particular modification.īelow are listed all such lenses in chronological order of their publication, the names are indicated according to the spelling on the lens housing or near the front lens, and the optical design and the number of special elements are indicated: Sigma has the largest family tree of universal high-aperture zoom lenses. Perhaps the new lens has optimized / modified its insides. I did not find any other obvious differences. In the name of new items added 'Macro' and removed 'Aspherical', and also removed the mention of 'D F' ( Dual Focus). ![]() In short, the lens announced in 2004 is just a minor revision of the older one announced in 2001. The newer version of the gum looks more harmonious. the most obvious difference between lenses is different texture of the rubber bands of the focus ring and zoom.the newer lens got the prefix ' MACRO', but both lenses have the same minimum focusing distance of 40 centimeters and the same maximum magnification ratio of 1: 3.8.Why the 'D F' was removed from the box and instructions of the SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO is unknown. in fact, the SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO (from this review) is also a 'D F' lens, as it also has two focus mode switches (Canon EOS version only).And it is not yet known why the prefix 'was removed from the name of the newer version' aspherical'(both versions have aspherical elements in their optical designs). At the same time, the older lens on its original packaging, as well as in the instructions, had the inscription 'D F' ( Dual Focus), which is why the older version is often called ' Sigma df', making it difficult to identify a specific Sigma lens model. Old: 'SIGMA ZOOM 24-70mm 1: 2.8 DG' (near the front lens) + '24 -70mm EX ASPHERICAL'(on the case). different names, the new lens shown in this review: 'SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO'(near the front lens) +' Sigma 24-70mm 1: 2.8 EX DG '(on the body).SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO 3 years younger version SIGMA ZOOM 24-70mm 1: 2.8 DG EX ASPHERICAL.Therefore, I will not do a separate detailed review on the SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO, I will only point out some differences and give examples of photos. These lenses do not differ much, they use the same optical design and have the same other technical characteristics. SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO (the name is indicated according to its spelling near the front lens) is a logical continuation of the older lens SIGMA ZOOM 24-70mm 1: 2.8 DG (the name is indicated according to its spelling near the front lens). For the rest of the bayonets, the SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO lens was produced only with a screwdriver (focusing is carried out due to the focus motor built into the camera). Only for the Canon EF / EFS version uses the built-in focus motor and an additional switch focus mode. This review shows the version for Nikon cameras with Nikon F mount, but there are also modifications for Canon EF / EFS, Sigma SA, Pentax K, Sony A / Minolta A. The SIGMA ZOOM 24-70mm 1: 2.8 EX DG MACRO is a fast versatile zoom for full frame cameras. ![]()
