Reviews and Problems with Sigma 70-300mm F4-5.6 DG OS
Showing 1-10 of 13
20 November 2011
Conclusion: Overall, there are 16 elements built into 11 groups and a 9-blade diaphragm which enables an aperture range of f/4-5.6 to f/22-32. Another crucial difference is that this lens lacks the APO version's macro facility, the maximum magnification factor being 0.25x instead of 0.5x.
Pros: Sharpness is good at 300mm, even when using the largest aperture of f/5.6, Effective 4-stop optical stabiliser, Robust build quality
Cons: Autofocus motor is quite noisy in operation, Front element extends and rotates during focusing, Lacks the 0.5x macro facility of Sigma's older 70-300mm APO lens
Excerpt: ePHOTOzine resident lens tester, Gary Wolstenholme casts his discerning eye over the Sigma 70-300mm. It has long been a popular choice amongst budget-conscious photographers looking to cover this popular range.
Pros: Good resolution at shorter focal lengths, Optical Stabiliser, Low Distortion at 70mm
Cons: Rotating AF ring, Drop off in resolution and contrast at 300mm, Slow focusing speed
Summary: Overall, Sigma’s lens performed very well and field testing suggests it loses nothing by offering only single-mode image stabilisation. At some £300 on-the-street, this looks rather a bargain.
Excerpt: Originally posted 2010-03-16 on Optyczne.pl The Sigma 70-300 mm f/4-5.6 APO DG Macro model was undoubtedly one of this company’s best-sellers.

Cons: too low image quality at the edge of full frame,, noisy autofocus motor.
Excerpt: Out the box it comes with a plastic lens hood that fixes via a bayonet fitting, though attaching this did cause the front element to wrench around. The lightweight lens felt well balanced when fitted to our Nikon D5100, and had a lovely smooth zoom action, though when switching over to MF we found...
Conclusion: Like all telephoto zooms, the Sigma loses a little definition at its maximum focal length, but the overall sharpness is above average, the contrast is good and there’s very little chromatic aberration or distortion, even at full zoom.

Excerpt: Fazit: Eine ordentliche Leistung zum fairen Preis bietet das Sigma 4-5.6/70-300 mm DG OS im Test. Sowohl in puncto Auflösung, als auch Objektivgüte liefert das Tele-Zoom für Vollformat-Kameras stattliche Ergebnisse. Lediglich der Autofokus könnte zügiger und treffsicherer scharfstellen.
Pros: Viel Zoom, Preis, Geringe Abbildungsfehler, Vollformat-geeignet
