Slight improvement is seen in the periphery at f/5.6, but across the frame image quality is very good at f/4.Īt 28mm, the f/2.8 center of the frame image quality remains sharp, but the mid frame and corners take a hit – showing noticeable blur. Unfortunately, the latter is the case with this lens.Īt 24mm, this lens is very sharp in the center at f/2.8, with some softness showing in the mid and peripheral portions of the image circle.Īt f/4, the center shows slight improvement, but the mid and periphery show noticeable improvement. Sometimes I can easily and accurately describe the image sharpness a lens delivers in a couple of sentences and this usually reflects excellent image sharpness being delivered – or at least consistency over the focal length range.īut in other cases, I need several paragraphs to explain the complicated image quality a lens delivers. You want an f/2.8 (or wider) lens for that. While an image stabilized f/4 lens can be handheld in much lower light levels than a non-stabilized f/2.8 lens, stabilization does not help stop subject motion. If you want a stabilized 24-70mm f/2.8 lens, the Tamron 24-70mm f/2.8 Di VC USD Lens is your only option at this time. Optical Stabilization is not a feature of this lens. Having f/2.8 available is especially welcomed when shooting indoors or after sunset.Īnd having that max aperture available over the entire focal length range makes using f/2.8 a pleasure as wide open exposure settings do not change with zooming. If you want to blur the background or stop subject action with a zoom lens in this focal length range, f/2.8 is as good as it gets. There are currently no full frame compatible zoom lenses available with apertures wider than f/2.8. This range is somewhat lacking from a wide angle perspective, but a 112mm angle of view equivalence on the long end is quite welcomed and will allow better perspective with even tighter portraits. The 70mm end reaches to moderately tight portrait range.Īdd everything in between and your subject range becomes vast.ĪPS-C (1.6x FOVCF) format camera owners will see an angle of view equivalent to 38.4-112mm on a full frame DSLR. The 24mm end is great for landscape photography, for shooting indoors and in other tight places and for a wide range of other uses. Let's hit the university track and then the backyard for a couple of looks at this focal length range. Getting the focal length right is always my first step in selecting a lens for a particular use.Īnd when a lens has a focal length range covering my recommended general purpose range,Īs 24-70mm does, that lens is going to find itself being used more than the rest. Headlining the features of the Sigma 24-70 HSM lens is the price tag – this is the least expensive 24-70mm f/2.8 lens available as of review date.įor a low price, you get good stopped-down image quality in a nicely-built full frame-compatible lens. The 24-70mm f/2.8 EX DG HSM is Sigma's latest version of this lens and this one comes in a mount for all of the just-mentioned cameras (except Tamron as they do not currently make cameras). I am of course referring to the ultra-useful 24-70mm f/2.8 lens.
