Canon 2470 Vs Sigma 2470 Art Canon 2470 28 Ii
With 2 optically stabilized 24-70mm f/2.8 lenses hit the market this year, many are likely wondering how the third-political party lenses stack upwards against Canon's venerable – though unstabilized – EF 24-70mm f/two.8L 2 USM. Let's have a skillful look at the Canon EF 24-70mm f/2.8L 2 USM, Sigma 24-70mm f/2.8 DG Os HSM Art & Tamron 24-70mm f/ii.viii Di VC USD G2 to notice out which might brand the all-time choice for ain general purpose needs.
Get-go, it's important to consider that these lenses are very similar from a primary features perspective, with built-in stabilization being the near notable differentiator. With that in heed, let'due south have a look at the shared set of features for these lenses:
Catechism 24-70L II, Sigma 24-seventy OS Art & Tamron 24-70mm VC G2 Shared Features
- Focal length range: 24-70mm
- Maximum aperture: f/ii.8
- Filter size: 82mm
- Some degree of weather sealing
Now, let'southward see how these 24-70mm lenses differ from a blueprint perspective:
Canon 24-70L II, Sigma 24-70 OS Art & Tamron 24-70mm VC G2 Differences
| Lens | Size | Weight | FRR1 | ZRRtwo | Focus/Zoom Band Rotation Direction |
| Canon EF 24-70mm f/ii.8L Ii USM | 3.48 x four.45" (88.5 x 113mm) | 28.4 oz (805g) | 105° | lx° | Canon standard |
| Sigma 24-70mm f/2.eight DG OS HSM Art | 3.46 x 4.24" (88 x 107.6mm) | 36 oz (1020g) | 95° | 64° | Canon standard |
| Tamron 24-70mm f/ii.8 Di VC USD G2 | 3.48 x iv.40" (88.4 10 111.8mm) | 31.9 oz (904g) | 110° | 75° | Nikon standard |

Sharpness Comparison
When it comes to sharpness, it'south difficult to fairly describe which lens is the foam of the crop. The reason is simple – the "sharpest lens" title changes depending on the focal length and aperture called forth with the specific surface area of the frame beingness considered.
After pouring over the results for quite some fourth dimension, I decided to compile my ain subjective findings. You can observe them below. However, I encourage you lot to compare the lenses for yourself at the focal lengths and apertures you volition likely utilize near to determine which lens may exist sharpest for your specific intended uses.
For the results below, I ranked the three lenses at each specified focal length / discontinuity. If there was little or no discernible departure between two lenses, then I marked the comparison a tie.
Equally you can encounter, at that place isn't necessarily a clear-cut winner from a sharpness standpoint when taking into consideration varying focal lengths, apertures and areas of the frame. However, notation that the Catechism EF 24-70mm f/ii.8L II USM was either the highest ranked or tied for first in the center of the frame in every test.
Vignetting Comparison
Vignetting performance is not a significant differentiating factor for this group of 24-70mm f/two.8 lenses. There are small-scale differences, but... none that would likely motivate you to choice 1 over the other solely based on corner darkening. If precise vignetting performance is a priority for you, check out the links below.

Vignetting: Canon EF 24-70mm f/2.8L 2 USM vs. Tamron 24-70mm f/two.8 Di VC USD G2
Vignetting: Sigma 24-70mm f/2.8 DG OS HSM Art vs. Tamron 24-70mm f/2.8 Di VC USD G2
Flare Performance
When evaluating flare performance, I typically compare lenses at f/16 at their widest and longest focal lengths. These comparisons ordinarily give me a adept idea of what to expect from the lens in near worst-example scenarios. Keep in heed that one'due south preference for tolerable types of flare is very subjective. Personally, I'd rather accept an overall lose of contrast as opposed to clearly defined rings, circles and lines which are difficult to remove in post-processing and may block important details in the frame.
In this comparison, the Canon 24-70L II trails the Sigma and Tamron lenses at 24mm and f/16, at least equally far as my personal preference is concerned.
Flare: Canon EF 24-70mm f/two.8L II USM vs. Sigma 24-70mm f/2.8 DG OS HSM Art
Flare: Canon EF 24-70mm f/2.8L II USM vs. Tamron 24-70mm f/ii.viii Di VC USD G2
Between the Sigma Fine art and Tamron G2, the design of flare artifacts is very similar, although the Sigma may show a fiddling more dissimilarity.
Flare: Sigma 24-70mm f/2.viii DG OS HSM Art vs. Tamron 24-70mm f/2.8 Di VC USD G2
At 70mm, the Canon still shows more conspicuously defined flare artifacts while the other two lenses show less overall contrast. It's difficult to pick a winner betwixt the Sigma and Tamron lenses, but if pressed to pick one, I call back I would prefer the Sigma's results.
Distortion
Zoom lenses typically exhibit barrel distortion at the wide end which transitions to pincushion distortion at the long end, and all of these lenses show these quintessential characteristics to varying degrees. Equally with vignetting, I don't think in that location is enough difference among the lenses to regard distortion as a major differentiating factor. Yet, if minimal distortion is a priority for you lot, compare the lenses at your about-used focal length to encounter which i will piece of work all-time for your needs.

Distortion: Sigma 24-70mm f/2.eight DG Bone HSM Fine art vs. Tamron 24-70mm f/2.8 Di VC USD G2
With image quality sufficiently covered, permit's dive into other aspects of the lenses to illuminate even more (likely more significant) differences.
Stabilization
Unlike most of the paradigm quality comparisons in a higher place, this comparing is very straightforward – the Canon 24-70L II doesn't accept built-in stabilization, while the Sigma and the Tamron lenses do. Between the 2, the Sigma 24-70 Art seemed to provide slightly more than handheld assistance in our tests.
Earlier nosotros move on, I should betoken out that stabilization can take a huge impact on image quality, as a lens tin can only accomplish its highest image quality when camera shake is neutralized (either by the use of a fast shutter speed or by lens/camera stabilization). Of form, stabilization does not assistance if your subject is moving, but... information technology can help a corking deal when photographing stationary subjects.
Autofocus Performance
Generally speaking, you'll get the best AF performance – especially in regards to accuracy and consistency – when using Canon lenses with Canon cameras. In the case of the Catechism 24-70L II, Sigma 24-lxx Os Fine art and Tamron 24-lxx VC G2, while the third party lens manufacturers have certainly airtight the performance gap over the past few years, the general dominion nonetheless applies.
The good news is that all of the lenses perform quite well when using the middle AF signal, assuming a proper autofocus microadjustment (AFMA) calibration. Unfortunately, AF operation degrades noticeably while utilizing the outer AF points with both the Sigma Art and Tamron G2 lenses. Our testing indicates that the Sigma is a little more consequent than the Tamron with outer AF signal use.
Those who don't mind employing a focus-and-recompose technique or otherwise can utilize Alive View focusing for prototype capture, can maximize their in-focus accept habitation percent when using third-party lenses.
1 area where the 3rd-party lenses are advantaged is autofocus calibration through the apply of Sigma's USB Dock and Tamron's TAP-in Console. While many loftier-cease Canon DSLRs have the ability to fine tune AF using AFMA, most consumer-to-mid-level Canon DSLRs do not have this feature. And fifty-fifty if your photographic camera does feature AFMA, the USB Dock and TAP-in Console let for effectively command of adjustment options (including split adjustments for varying focus distances). Another do good of dock-adjusted AF is that a lens tin can exist calibrated once for use on several bodies (assuming the same adjustment is necessary throughout the set) instead of having to enter the aforementioned adjustment value in-camera on several bodies.
Price
Toll is 1 lens aspect that is quite like shooting fish in a barrel and straightforward to compare. The Canon 24-70L Two is the most expensive lens of the bunch, with the Sigma'southward toll being nigh 30% lower than the Canon'southward (current MSRP in North America, no rebates). The Tamron is priced slightly less than the Sigma.
One thing to keep in listen when choosing to invest in a lens is the make's typical resale value. Of the 3 manufacturers, Canon lenses tend to hold their value better than the third-party options.
Summary
By not including paradigm stabilization in the EF 24-70mm f/2.8L 2 USM lens, Catechism left the door wide open for third-party manufacturers to produce an even more versatile and/or enticing general purpose lens. Both Sigma and Tamron saw the crevice in Canon's armor, and the introduction of the 24-70mm f/2.eight DG OS HSM Art and 24-70mm f/2.eight Di VC USD G2 lenses correspond the culmination of those manufacturers' efforts to unseat Canon in the professional person general purpose lens market past taking reward of Canon's biggest shortcoming.
Has either make succeeded? In some ways the answer is "yes," and in other means, "no." None of the lenses in this comparison blew away the competition, with the "all-time lens" being different based on one's own personal preferences and requirements. For those that cannot afford to miss a shot and prefer using viewfinder AF along with outer AF points (think, wedding ceremony photographers), the Canon EF 24-70mm f/2.8L II USM will probable exist all-time. For the ultimate in versatility, however – thanks in large part to in-lens stabilization – the Sigma 24-70mm f/two.8 DG OS HSM Art and Tamron 24-70mm f/2.8 Di VC USD G2 both offer compelling operation at a more budget friendly price. Ultimately, the choice between the Sigma and Tamron will likely hinge on one's preference for more accurate AF (Sigma) or increased potential sharpness (Tamron).
