Description by Canon:

A professional-quality standard zoom that offers superlative image quality and a fast f/2.8 maximum aperture throughout its zoom range. The perfect companion to any full-frame EOS camera.


The Tamron SP 24-70mm f/2.8 Di VC USD excels at the DXO Mark bench: "When mounted on a Canon 5D Mark II, the Tamron SP 24-70mm F2.8 Di VC USD achieves an overall DxOMark Score of 24, the 2nd highest score in our database for a high-speed zoom."

So, the Tamron manages to closely match such expensive and optically well endowed lenses as the Canon 24-70mm f2.8L USM II, and the Nikkor 24-70mm G ED, both costing around the 2 grand mark in every major western currency:

"The Tamron SP 24-70mm f/2.8 Di VC USD is in the top three best performing high-speed standard zooms currently available. We’ve only looked at the imaging performance, but it’s as impressive optically as the highly regarded Nikon AF-S Nikkor 24-70mm f2.8G ED. At $1,299 it’s not cheap but it is competitively priced – to improve on the image quality you would have to spend $1,000 for the sublime Canon EF 24-70mm f/2.8 II USM. Dropping down . . . read more

The Canon EF 24-70mm f/2.8L II USM lens grabs the 'best in class' award at DXO Mark, as the highest scoring professional fixed-aperture mid-range kit zoom of any brand, but scores very high in the price department too.

"With an DxOMark score of 26, the Canon EF 24-70mm f/2.8 MkII is the highest scoring professional fixed-aperture mid-range kit zoom of any brand in the DxO Mark database and comfortably outperforms rivals as well as the firm’s earlier Mark I version, particularly with regard to the sharpness levels across the frame. We’re used to seeing a noticeable deterioration in performance in the outer fields at longer focal lengths even with high-quality optics from the big-name marques but the new Canon bucks that trend. . . . read more

Canon EF 24-70mm f/4L IS USM lens Review by Mark Goldstein at the Photography Blog: If you can afford the hefty price tag then we can highly recommend the Canon EF 24-70mm f/4L IS USM as an excellent standard zoom lens for Canon full-frame DSLR owners.

The Lens was tested with a Canon EOS 6D Full frame camera. On a cropped Dslr its reach would be between the 'not wide enough' and 'not long enough'.

"The Canon EF 24-70mm f/4L IS USM is a very capable but also very pricey standard zoom lens that will appeal most to wedding and reportage photographers looking for a lightweight and responsive lens. It also usefully doubles up as a competent macro lens, perhaps saving the extra expense and space required by another dedicated optic.Given its L-series billing, the Canon EF 24-70mm f/4L IS USM build quality is reassuringly excellent and it makes a perfect partner to a full-frame Canon DSLR like the EOS 6D that we tested it with. Auto-focusing is quiet and quick, with the ability to manuall . . . read more

Roget Cicala at RelsRentals dissects the Canon 24-70mm f/2.8 Mk II, the Nikon 24-70mm G ED f/2.8 AF-S, and the Tamron 24-70 f/2.8 Di VC, just to see what they look like from the inside.

"We’ve been doing a lot of teardowns lately and I’ve made comments like “well thought out” or “carefully engineered.” Several people have asked me to show them some comparisons so they can see what I’m talking about. Given that we have fairly modern releases of 24-70mm f/2.8 lenses from several manufacturers, we thought it would make sense to compare what the insides look like.

This will largely examine the electro-mechanical mechanisms in the lenses. But just for completeness here are the optical diagrams for all 3. The Canon is the most optically complex, containing 18 elements in 13 groups. The Tamron has 17 . . . read more

Canon EF 24-70mm f/4 L IS USM lens review by Ken Rockwell: The Canon 24-70mm f/4 L is excellent. Its sharpness varies very little from center to edge and stays about the same with aperture changes.

The lens was tested with a Canon 5D Mark III Dslr body:

"So long as you're in focus, sharpness doesn't vary much from perfection, except by f/11, where diffraction softens the image. Hey, sorry to spare you endless boring charts, but with a lens this good, there's nothing to show other than sharp pictures under all conditions. With a lens profile on my Canon 5D Mark III or similar camera, falloff is never visible at any setting. Flare and ghosts are very well controlled, but if you push it, you will get a green dot or two. . . . read more

Canon EF 24-70 mm f/2.8L II USM lens review at LensTip: Better than its predecessor, but the competition has also moved on, without hiking the price like Canon did.

"I admit that, while writing a summary of this test, my feelings are mixed. On the one hand I am pleased that the new lens is much better than its predecessor in almost all categories. Its high build quality and good optical properties are exactly those features professional photographers are looking for. In regard to that aspect the lens won’t disappoint you for sure.

On the other hand the competitors also didn’t let the grass grow under their feet and their new 24-70 mm f/2.8 products . . . read more

Canon EF 24-70mm f/2.8L II USM Review at SLR Gear: As good as it gets with L glass zooms, at a price.

"Obviously on a sub-frame camera the corners of the lens are not examined by the sensor, so it's not surprising that we see a bit worse performance in the corners with the lens mounted on the full-frame Canon 1Ds mkIII. Performance is still very good when used at the ƒ/2.8 setting; from 24mm to 70mm, we see a sharp central region with some corner softness in each focal length. The lens never shows the tack-sharp results it does when mounted on a sub-frame camera, but the corners are only slightly soft. When diffraction limiting sets in at ƒ/11, it also serves to equalize the corners with the center . . . read more

Canon EF 24-70 f/2.8L II review at Canon rumors: Excellent image quality, but better wait to buy when price starts coming down.

"All-in-all, this is a worthy upgrade of a pretty classic lens. Is it $1000 better than the previous version? No, I don’t think it is. When it starts to fall below $2000 in a year or so, I think it’s a good value lens. If you’re budget minded, go grab yourself a used version 1 and be happy, it’s still a great lens. If you want the best 24-70 on the market and don’t mind paying for the privilege, you won’t be disappointed with the EF 24-70 f/2.8L II. " . . . read more

Roger Cicala pits armies of Canon EF 24-70mm fL 2.8 USM mark I vs mark II, finds huge differences.

"When I tested that first small batch of 24-70 Mk II lenses I said they were a bit sharper at 70mm than even the legendary Canon 70-200 f/2.8 IS II lens was. The 24-70 resolved 950 Line pairs / Image height at the center, and 810 overall, compared to the 70-200′s 885 / 765. . . . read more

Canon EF 24-70mm f/2.8L II USM Lens Review at Ephotozine

Canon has gone completely wild with the pricing of this one. It demands more than twice  of what the previous 24-70mm lens used to cost, and a good 1000 $/£/€ more than the excellent Nikkor equivalent. So, is it worth the premium? (Spoiler: no, of course not).

"Sharpness in the centre of the frame is very good to outstanding throughout the zoom range. At 24mm and f/2.8 sharpness . . . read more

Canon EOS-1D X and EF 24-70mm f/2.8L II USM lens delayed, again.

This is the third delay-so far, for the 1D x. Canon USA confirms:

"Updated sales start dates for the EOS-1D X and EF 24-70mm F2.8L II USM lens

Canon releases EF 24-70 F/2.8L II USM, adds features, but no Image Stabilization.

After more than untold years in waiting we can finally behold the 'wedding master' EF 24-70 F/2.8L II USM . Here's what's new:

A Super UD lens element, and two standard UD elements, 9 blade diaphragm, better weather proofing, and fluorite coating on the front lens. Also, a zoom lock switch. As expected, there's no image stabilization, and the usual price hike.  I mean, what's the freaking point in including stabilization in a 24mm prime, and not in a 24-70mm super expensive zoom lens? . . . read more
