Sigma 18-125mm F/3.5-5.6 DC reviews, sample shots, and full specifications
The Sigma 18-125mm F/3.5-5.6 DC sharpness is very consistent through out the aperture range. Lens is sharpest at f5.6 and f8 at full wide angle and full telephoto respectively. The difference of sharpness between widest aperture and optimal aperture is minimal. The lens says f3.5-5.6 and it is really good at f3.5-5.6, Unlike the Canon EF-S 18-55mm f/3.5-5.6 and Canon EF 50mm f/1.8 II that says f/3.5-5.6 and f/1.8 but you wouldn’t really want to use them at those appertures.
This lens give me an ideal zoom range for most challenging situation. The 18mm focal for my EOS 20D works nearly as 29mm in normal SLR. Not very wide but good enough for group photo of seminar attendess to landscape and cityscape. Too bad that I always have to put the lens hood on to prevent flare.
At 125mm it works as if I use 200mm lens! That’s great for photographing architectural details of old buildings, candid shots of people or shooting birds on a wire.
