The difference was admittedly a minor one, in most cases, but visible outside of laboratory conditions.

Matthew Gore | Light And Matter Resolution and SharpnessĪfter reviewing the Sigma 24-70 f/2.8 OS ART for Canon mount, I didn’t have particularly high hopes for the new Sigma 24-70 model for mirrorless, so I was pleasantly surprised to discover how well the new lens performed.Īt the wide end of the zoom (tested at 28mm), the Sigma produced noticeably better resolution than the Tamron across the frame, from center to corner. 1 By backing up, you’re adding more foreground into the image, and what used to be foreground in the image before backing up will seem smaller in comparison to the subject or mid-ground after backing up. Backing up and taking the photo from a further distance may be a workaround in some circumstances (when the subject is close enough to you that backing up will make a difference), but even then, you’ll be changing the distance relationships between the foreground, background, and subjects in the photo.

Tamron it is possible to completely reproduce the perspective of a 75mm lens with a 70mm lens and cropping, the same is not true at the other end of the zoom range there is no substitute for a wide lens.

How much of a difference is there between 24mm and 28mm? A significant amount, though after getting used to the 28mm end of the Tamron, I’ve rarely felt that I needed anything wider over the past couple of years… except when I needed something much wider (for which I bought the Tamron 17-28mm f/2.8).

If you’re young and healthy and don’t mind an extra half pound of weight, the Sigma will pose no problem.

While the Sigma lens is physically shorter and lighter than the Sony 24-70 f/2.8 GM (5.35″ long, 1.95lbs), it is still substantially larger than the Tamron 28-75 the Sigma weighs 1.84 pounds compared the the Tamron’s 1.21, about 65% as much as the Sigma.
