Sony 24-70mm F/2.eight GM lens review:

Every photographic camera make makes a holy trinity of lenses: wide angle, normal zoom and telephoto zoom with fixed ii.eight aperture. Of those three lenses, the normal zoom, the 24-70mm F/2.8 is the most common and necessary tool for photographers. With a range suitable for everything from landscapes to portraits, it can usually be a walk-effectually lens for the almost demanding photographers. It is a staple for wedding photographers who demand high quality, fast aperture and the convenience of a zoom. In my time reviewing the Sony 24-70mm F/ii.8 GM, I used it for a wedding ceremony on both the Sony A9 and Sony A7riii.

When Sony launched their full frame mirrorless organization, they first concentrated on more compact lenses. Sony's kickoff two zoom lenses consisted of the variable discontinuity 28-70mm and a 24-70mm F/4. In 2016, Sony released the ultra-premium 24-70mm F/two.viii GM (Grand Master). For years, Sony used "One thousand" and "Zeiss" designations to connote their premium lenses, which they connected with their total frame mirrorless lenses. In 2016, with the Sony 24-seventy F/two.8 and Sony 85mm F/1.4, they began to utilize the "G Master" designation, to connote lenses theoretically superior even to their "K" and "Zeiss" lenses.

Sony prices the 24-70mm F/ii.8 GM at a premium of around $2200. Let's meet if it's worth the loftier price tag…

The Sony 24-70mm F/2.8 GM definitely feels like a well crafted precision instrument in the mitt. The weather sealed body feels like a well-equanimous combination of metal and plastic, with nicely grooved focus and zoom rings. There is a focus lock button to prevent zoom creep, though I found the zoom to offer a practiced amount of resistance without existence as well tight. There is an AF/MF switch and a focus hold button, which is of great benefit when re-programmed for eye-AF.

Below, come across the Sony 24-70mm F/2.8 GM compared to the Tamron 28-75mm F/2.8 and Sony 24-105mm F/4 M.

Tamron 28-75 vs Sony 24-70GM vs Sony 24-105G

The Sony 24-70mm F/two.eight GM is not a small lens by any definition. It stands as proof that mirrorless isn't always smaller. With a weight of 886 grams, it falls right within the range of similar lenses from other manufacturers: Canon's 24-70mm F/two.eight is noticeable lighter at 805 grams, Nikon's unstabilized 24-70mm F/2.eight is very close at 900 grams (though their newest stabilized lens is a whopping 1070 grams), and Tamron's stabilized version for Catechism/Nikon is 898 grams.

Compared to other normal zoom lenses for Sony, the Tamron 28-75mm F/2.eight weighs merely 550 grams and the Sony 24-105mm F/four Thousand weighs 663 grams. Thus, compared to other normal zoom options for Sony, you are taking on a lot of extra weight and cost.

Autofocus was fast and silent in my testing. Unfortunately, after I returned the lens I noted an consequence in some of my images: At smaller discontinuity (F8 and smaller), in images where I used flash, there was meaning back-focus. This could signify focus shift every bit the aperture changes. or may have been elementary missed focus by the camera. I did not examination it extensively so I can't say definitively whether it is an effect with the Sony 24-70mm F/two.eight, only I would recommend beingness enlightened of it.

The Sony 24-70mm F/2.8 GM does not have any form of optical stabilization. Any stabilization comes from the in-torso stabilization found in Sony's most electric current cameras.

Stabilization Tests:

50mm i/25

50mm ane/20

50mm 1/15

50mm one/10

Different lenses seem to play better or worse with Sony's in body stabilization system. In the above examples, the image at 1/tenth of a second is even so tack sharp while the images at 1/20th and 1/15th are exhibiting softness due to photographic camera shake. My testing demonstrated this inconsistency on an ongoing basis. I've gotten far more consequent results from lenses also equipped with OIS, similar the Sony 24-105mm F/4 Chiliad. With the 24-70mm F/4 GM, I was able to become a off-white number of precipitous images fifty-fifty at i/10th of a second and 50mm. Simply at the aforementioned time, I lost a fair number of images fifty-fifty at 1/25th of a second.

Overall, I'd resist shooting the 24-70mm F/2.8 at any slower than half the speed of 1/focal length rule. (In other words, at 24mm, no slower than well-nigh 1/ten. At 50mm, no slower than 1/25. At 70mm, no slower than about 1/xxx or i/40). Yous will become some sharp images fifty-fifty at much slower shutter speeds but not with bully consistency.

Image Quality

The point of 24-70mm F/2.8 lens is to become "prime number similar" image quality with the convenience of a zoom lens. This should exist the accented all-time standard zoom you tin can buy or it wouldn't be worth the price and the weight.

Vignetting

24mm f/ii.8 vignette

24mm F/4 vignette

24mm F/5.half dozen vignette

Every standard zoom lens I've tested on the Sony A7riii presents a similar effect at the wide end, when wide open. Vignetting is usually a gradual concealment as you go towards the corners. Every lens I've tested on Sony get an abrupt blacking at the extreme corners. This may exist due to the front elements of the lens being but a fleck likewise small, information technology may be due to the challenges of designing for the narrow diameter of the Sony Atomic number 26 mount. Regardless of the reasons, information technology is clearly nowadays in uncorrected files. It is less astringent in the Sony 24-70mm F/two.8 GM only it is definitely present. By F4, the vignetting is significantly improved and not noticeable past F/5.half-dozen. In real world shooting, vignetting won't exist a concern. It's similar at 70mm:

70mm vignette at f/2.8

70mm vignette at f/4

70mm vignette at f/6.3

70mm corrected:

70mm vignette at f/2.8

70mm vignette at f/ii.viii – lightroom corrected, not entirely stock-still

Once again, we get some slight corner blackening at F/2.8. The lightroom contour mostly corrects it. In real world shooting, I don't meet it as an issue.

Flare – Chromatic Aberration/Imperial Fringing – Sun stars

flare at 65mm F/ii.eight

flare at 57mm f/2.8

flare at 57mm F/5.0

flare at 57mm F/9

flare at 48mm F/2.8, no regal fringing

My testing did not testify any color shifting, purple fringing or chromatic aberration. Even in extreme backlighting, the Sony 24-70mm F/2.viii GM maintains great contrast.

The Sony 24-70mm F/2.8 is prone to flare at all apertures merely equally shown in the above examples, information technology is adequately innocuous flare. Information technology's the type of flare some photographers may even consider "artistic" as opposed to ugly blotchy flare you lot get with some lenses.

At F14, nosotros get flare simply a good sunstar:

Bokeh

I most always prefer the bokeh from prime lenses. Zoom lenses have more complicated designs, more internal components, which tend to disrupt the smoothness of the bokeh (the quality of the out of focus image).

F2.8 bokeh

F9 bokeh

When analyzing bokeh, bokeh snobs will look at the quality of the out of focus highlights — the bokeh balls. The good news is that the bokeh balls maintain a squeamish round shape even when stopped down to F9. The bad news is that the bokeh balls are more harshly outlined than you would get with nearly prime lenses. Nosotros would conclude that "the bokeh is practiced for a zoom lens."

Distortion

24mm barrel baloney

24mm distortion corrected

70mm mild pin absorber distortion

70mm distortion corrected

pivot cushion distortion at 46mm

Butt distortion is noticeable at 24mm only is correctable. Merely annotation that corrections stop up stretching the edges of the frame, impacting sharpness. Every bit you lot zoom in, you get balmy but correctable pin cushion baloney.

Sharpness

Sharpness is the i matter that y'all actually can't right with software after the fact. Nearly all lenses get sharper when stopped down a bit. This benefits the sharpness of prime number lenses as they are stopped down at F/2.eight. The betoken of spending $2200 on a zoom lens is to exist able to approach this level of sharpness without the need to stop down significantly. Let'southward encounter how the Sony 24-70mm F/2.8 GM fares:

24mm Sharpness Tests

Starting with center crops at 24mm (click for big):

center at 24mm and f/2.8

center at 24mm and f/4

heart at 24mm and f/v.half-dozen

eye at 24mm and f/8

24mm at the aps-c border:

border at 24mm and f/ii.8

border at 24mm and f/4

border at 24mm and f/eight

And 24mm in the farthermost corners:

corner at 24mm F/ii.8

corner at 24mm and f/4

corner at 24mm and f/v.6

corner at 24mm and f/8

Another serial from closer focus:

Centers at 24mm:

24mm center at f/2.8

24mm centre at f/iv

24mm middle at f/5.6

24mm middle at f/eight

Borders at 24mm:

24mm border at f2.8

24mm border at f4

24mm border at f5.6

24mm border at f8

And the extreme corners at 24mm:

24mm corner at f2.8

24mm corner at f4

24mm corner at f5.6

24mm corner at f8

At 24mm, the summary is pretty simple. The center is brilliant at all apertures but reaches peak sharpness at F4. The borders are acceptably precipitous wide open at F/2.8 just become tack sharp at F4. The corners are very soft at F/2.viii (I've seen worse) but they gradually improve as you stop downwardly. By F4, the corners are adequate merely they don't ever approach tack sharpness until F8. That said, for nigh real world uses, the entire frame volition be acceptably abrupt at all apertures. For the almost enervating huge landscape prints, the image volition be just fine from F4 onward.

35mm Sharpness Tests

Centers at 35mm:

center at 35mm and f/2.8

eye at 35mm and f/4

middle at 35mm and f/5.six

eye at 35mm and f/eight

Borders at 35mm:

edge at 35mm and f/2.8

centre at 35mm and f/4

border at 35mm and f/five.6

border at 35mm and f/8

Corners at 35mm:

corner at 35mm and f/two.8

corner at 35mm and f/four

corner at 35mm and f/5.6

corner at 35mm and f/8

35mm operation is very similar to 24mm performance though it may be a hair less abrupt. Centers and borders are more than adequate at F/two.eight. I wouldn't quite depict it as prime equivalent but it's close. The borders never become completely tack sharp but become quite acceptable at F4.

50mm Sharpness Tests

center at 50mm and f/ii.8

center at 50mm and f/four

centre at 50mm and f/five.6

center at 50mm and f/8

The borders:

border at 50mm and f/2.viii

border at 50mm and f/four

border at 50mm and f/5.six

border at 50mm and f/viii

50mm corners:

corner at 50mm and f/2.8

corner at 50mm and f/v.half-dozen

corner at 50mm and f/8

Closer focus, centers at 50mm:

50mm center at f/two.eight

50mm center at f/4

50mm centre at f/5.6

50mm centre at f/eight

50mm borders:

50mm edge at f2.eight

50mm border at f5.6

50mm border at f8

And extreme corners at 50mm:

50mm corner at f2.8

50mm corner at f4

50mm corner at f5.vi

50mm corner at f8

I'm very happy with the results at 50mm. The centers and borders are tack sharp at all apertures. The corners are fairly adequate at 2.8 and become tack sharp with a bit of stopping down.

70mm Sharpness Tests

center at 70mm and f/ii.8

center at 70mm and f/four

center at 70mm and f/5.vi

center at 70mm and f/eight

70mm border crops:

border at 70mm and f/2.viii

edge at 70mm and f/four

edge at 70mm and f/5.6

border at 70mm and f/8

Finally, 70mm farthermost corner crops:

corner at 70mm and f/2.viii

corner at 70mm and f/4

corner at 70mm and f/5.vi

corner at 70mm and f/8

The closer focus series, 70mm centre:

70mm center at f/ii.viii

70mm center at f/4

70mm heart at f/5.6

70mm center at f/eight

70mm borders:

70mm edge at f/two.8

70mm border at f/4

70mm border at f/5.half-dozen

And finally, 70mm extreme corners:

70mm corner at f/2.eight

70mm corner at f/four

70mm corner at f/5.6

This are a scrap weaker overall at the long end simply that's with nitpicking. The center is certainly abrupt even wide open but benefits from stopping downwardly. The borders attain acceptable levels of sharpness wide open up merely don't become tack abrupt until at least F4. The corners are simply slightly soft through the aperture range, only getting close to tack sharp at F8. In real world shooting, you lot'll certainly get usable results at 70mm.

In sum, you volition get real earth usable results at all focal lengths and apertures. Merely you won't quite achieve the pixel peeping level of sharpness across the frame that volition exist achieved with good prime lenses.

Bonus: Compared to Sony 24-105 F/4 and Tamron 28-75mm F/two.8

The top ii competing standard zoom lenses are the Sony 24-105mm F/4 Grand (reviewed here) and the Tamron 28-75 F/two.8 (reviewed hither). Both lenses cover a similar range as the Sony 24-seventy F/2.8 GM with considerably less weight and less toll. The Sony 24-105 F/4 1000 covers more range but at the price of ane stop in discontinuity. The Tamron manages the same aperture simply loses 4mm on the wide terminate. For a full comparison, read the full reviews. Only for purposes here, let'southward see how all three lenses compared head to caput, at 50mm.

Showtime, middle crops at F/2.eight and F/iv.

24-70GM at 50mm F/2.8 center

24-70GM at 50mm F/4 center

Tamron 28-75 at 50mm f/2.8 heart

Tamron 28-75 at 50mm f/4 center

24-105 at 50mm at f/4 center

50mm is strong for all three lenses in the center. Both the Sony 24-70mm F/two.8 GM and the Tamron 28-75mm F/2.8 are tack precipitous in the eye, specially at F4. As the Sony 24-105mm F/4 is wide open at F4, it is just a tad softer in the center.

Edge crops at F/ii.8 and F/4:

24-70GM at 50mm F/2.8 edge

24-70GM at 50mm F/4 border

Tamron 28-75 at 50mm f/ii.8 border

Tamron 28-75 at 50mm f/4 border

24-105 at 50mm at f/4 border

Performance is very even here. The Sony 24-70mm F/2.viii GM and the Tamron 28-75mm F/two.viii are equally sharp at F/two.8 and both equally sharpen upwardly further at F4. The Sony 24-105mm F/4 manages to compete quite well but falls only a hair behind at F/iv.

Corner crops at 50mm and F/2.viii and F/4

24-70GM at 50mm F/2.8 corner

24-70GM at 50mm F/4 corner

Tamron 28-75 at 50mm f/2.8 corner

Tamron 28-75 at 50mm f/four corner

24-105 at 50mm at f/4 corner

The corner assay is the outset time nosotros really see the Sony 24-70mm/F2.eight pull ahead. At ii.8, the Tamron corner is quite ugly and is only okay at F/4. The Sony 24-105mm F/4 isn't horrendous but it slightly softer than the Tamron in the corner at F/iv. Meanwhile, the Sony 24-70mm F/2.eight GM produces a near acceptable corner at ii.8 and is pretty darn precipitous at F4.

If one examined the full focal length range, they would achieve similar results: At F4, the Sony 24-105mm F/4 falls just a hair behind. Meanwhile, the Tamron 28-75 competes very well in the center and borders but has generally weaker corner performance.

Overall:

From an optical perspective, the Sony 24-70mm F/ii.8 GM is the best standard zoom money tin buy. The build quality is excellent. There are no pregnant image quality defects. Sharpness is quite proficient overall, often rivaling prime lenses.

Yet, Sony enthusiast shooters have other choices. Of course there is the kit 28-70mm for under $300 and the Sony 24-70mm F/4 which runs $900. I don't believe either of these lenses are suitable for demanding enthusiast photographers merely there are two other lenses that should be considered: the $1300 Sony 24-105 f/iv (now in stock at Amazon ) or the Tamron 28-75mm f/2.8 for under $900.

Comparing the Sony 24-70mm F/2.8 GM to the Sony 24-105mm F/iv G:

The Sony 24-105mm F/4 Yard weighs 25% less
Sony 24-105mm F/iv One thousand costs $900 less
35mm more range on the long end of the Sony 24-105mm F/4 Thou
Aperture is one stop faster on the Sony 24-70mm F/2.eight GM
Sony 24-70mm F/2.8 is slightly sharper at aforementioned apertures
Thanks to OIS, improve stabilization on the Sony 24-105mm F/4 G

Many enthusiasts would be improve served with the Sony 24-105mm F/iv Thou, peculiarly if yous also accept prime lenses in your handbag for when you really exercise need wider aperture. The 24-70mm F/2.viii GM is a ameliorate tool for those who wish to forego conveying prime lenses.

Buy the Sony 24-105mm F/four from Amazon hither.

If you lot exercise demand the 2.8 aperture, comparing the Sony 24-70mm F/2.8 GM with the Tamron 28-75mm F/2.8:

$800 price difference making the Tamron 28-75mm F/2.8 less than 2/5ths the price of the GM
The Tamron weighs 40% less than the Sony 24-70mm F/2.8 GM
The Sony 24-70mm F/2.eight GM has slightly higher IQ, especially in regard to vignetting and corner sharpness
The Sony 24-70mm F/2.eight GM is 4mm wider, which is more important than the 5mm the Tamron gains at the long finish.

If you lot don't care about weight or cost, become with the Sony 24-70 f/2.8 GM. It is the meliorate lens. If y'all are weight and price conscience, the trade offs of corner sharpness and 4mm on the broad end in the Tamron may be well worth the huge price and weight savings.

Y'all can purchase the Tamron 28-75mm F/2.8 from Amazon Hither.

Last Score:

I effort to stay objective in my lens reviews but my final score is based on my subjective balancing of functionality, usability, image quality, weight and cost. From a pure optical standpoint, every $2000 lens from every manufacturer is excellent but that doesn't make them "must own" gear for every enthusiast photographer. If you don't need the convenience of a zoom, fifty-fifty fairly cheap prime lenses volition evangelize similar paradigm quality. If you do value the convenience of a zoom, you tin get much cheaper and lighter lenses with only minor merchandise offs in image quality and discontinuity.

Thus, while the Sony 24-70mm F/2.viii GM is an excellent lens that will non disappoint buyers, when also considering the hefty weight and price from the perspective of an enthusiast, my concluding score:

Rating (1-10): Score: 7

(About my scoring: nine-ten is a superb lens which could accept a place in the bag of near every photographer. 6-viii: recommended with caveats. 3-five: A compromised lens that may still be suitable for some shooters and situations. one-2: Simply stick to your phone camera)
