The new 24-70 II is 24.8 oz (805g) versus 23.6 oz (670g) of the 24-105. Previous 24-70 f/2.8 users will appreciate the drastic reduction in weight, the shorter length and the smaller hood. Those coming over from Nikon now have a 24-70 f/2.8 with the sharpness that they were used on the Nikon platform in a lighter weight lens.
In general, the Sigma 24-70 f/2.8 ART’s resolution was excellent in the center of the lens. Depending on the the light and conditions, it was sometimes on par with the Canon 24-70 f/2.8L II comparison unit, though no better. However, away from the center, resolution was often quite bad. Take a look, starting at the 70mm end of the zoom range.
For an inexpensive “kit” zoom lens, the Nikon Z 24-70mm f/4 S shows amazing results. It is almost as sharp as its big brother in the center frame, but definitely loses out in the corners. At 35mm, both lenses do really well at f/4. However, once stopped down to f/5.6, the Nikon Z 24-70mm f/2.8 S shows visibly better corner performance in

The 24-70mm lens is generally offered in two variations: f/2.8 and f/4. This number refers to the maximum aperture offered by the lens: the f/2.8 version is able to use a wider f/2.8 aperture, whereas the f/4 version can only widen the aperture to f/4. As a result, the f/2.8 version can take in more light compared to the f/4 version.
At 24mm, the Canon 24-70 f/4L IS performs very well. At f/4, the Canon was noticeably sharper at 100%, though I wouldn’t call the differences drastic. However, at 50mm the tables were turned and the Tamron 24-70 f/2.8 VC was the clear winner here. Chromatic Aberration was more noticeable in the Tamron but it was not distracting at all to my eye.
has a silent focus motor built into the lens. Canon RF 24-240mm f/4-6.3 IS USM. Canon RF 70-200mm f/4 L IS USM. Lenses with built-in focus motor focus faster and more quietly than lenses without a focus motor which rely on the camera's body focus motor. minimum focus distance.
A shorter minimum focal length allows you to get more of the scene in the photo, and offers a wider angle of view than longer focal lengths. has built-in optical image stabilization. Canon EF 100mm F/2.8 Macro USM. Canon EF 24-70mm F/4L IS USM. Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera.
Canon RF 70-200mm F4 L IS USM Lens. 24.5. (695) 3.3 x 4.7. (83.5 x 119.0) 77. The F2.8 lens has a tripod mount ring, an advantage for rotating a camera mounted on a tripod or monopod, but the F4 lens isn't heavy enough to require such for balance purposes. The F4 lens has a modest maximum magnification advantage (0.28x vs. 0.23x).
Now the Nikon 24-70mm f/2.8E VR is as sharp in the center and significantly better everywhere else at f/2.8, and once stopped down to f/5.6, it takes off big time without letting the Tamron catch up. Overall, it is pretty clear that the Nikon 24-70mm f/2.8E VR is a much better lens sharpness-wise when compared to the Tamron 24-70mm f/2.8 VC.
