New [shoplink 6091]Canon EOS M (price & specs)[/shoplink] rumors surfacing. Canon Rumors reports that there will (or could) be three new lenses: a 55-300mm kind of lens, a fast prime and a super zoom, all along with a new EOS M body that should have a viewfinder (hooray!). Everything is still unconfirmed, but announcement could be in April 2013.
Let me start with a absolutely geek post by R. Cicala and lensrentals team. They teared down three lenses, among them the [shoplink 2160]Canon EF 24-70mm f/2.8 Mark II (price & specs)[/shoplink] (the other two are Nikon 24-70 f/2.8 AF-S and the [shoplink 5013]Tamron AF 24-70mm f/2.8 VC (price & specs)[/shoplink]). Tear down in the sense they opened the lenses and had a look deep inside. A pretty technical post that will appeal to the engineers among us. Lots of images of the various steps. Check it out!
The Digital Picture had a look at the image quality of the [shoplink 8251]Canon EF 24-70mm f/4L IS USM (price & specs)[/shoplink]. ISO 12233 resolution chart, distortion and vignetting test results are available. Excerpt:
The 24-105 L delivers a sharper image at 50mm f/4. Sharpness improvement at 70mm brings the 24-70 f/4 L IS back up to near equality with the 24-105 L. These two lenses perform more similarly at f/5.6 and at f/8, results from these two lenses are nearly comparable. Again, the results are similar at f/11.
Leaningcameras reviewed the Canon EF 24-70mm f/4 IS. In the conclusion they write:
The end result is that this is a great f/4 lens. It has stabilization which works extremely well, it is sharp, produces notably good results overall, and has the macro bonus.
The same guys also compared the Canon 24-70mm f/4 IS to the [shoplink 230]Canon EF 24-105mm f/4L IS USM (price & specs)[/shoplink], and talk about their findings in the following video:
They also made a video comparing the Canon 24-70mm f/4 IS to the Tamron 24-70mm f/2.8 VC:
Another comparison between the EF 24-70mm f/4L IS and the EF 24-105mm f/4L IS comes from Ketan Gajria’s blog. Samples and crops provided.

The makers of Lightroom Killer Tips (Scott Kelby and co) started a Lightroom magazine for the iPad. The first issue is free, next issues are $4.99 each. The magazine can be downloaded from the App Store (click here). They say:
A while back we realized that Lightroom has become the go-to program for photographers. Up until now, we’ve always included a section on Lightroom in our print magazine, Photoshop User. But after seeing just how passionate people are about Lightroom, we realized it needs it’s own magazine app.

Update: According to Japanese site dc.watch.impress the Metabones Speed Boost adapter will be on sale in Japan at the end of January 2013.
Update2: click here to read Metabones' white paper about the Speed Booster adapter. 30 pages of tech talk.
More About The Metabones Speed Booster. EOSHD did some simple but effective tests with Metabones' amazing Speed Booster adapter (we reported here). In short: the Metabones Speed Booster makes a lens wider and faster. Sounds like voodoo? It isn't, just clever engineering. To give a visual aid to what the adapater promises to deliver, have a look at the following two images. Only one was shot using a full-frame DSLR.
Did you guess which pic was shot with the full-frame camera? Both pics were shot using a Sigma 24mm F1.8 (price & specs). The top one using a [shoplink 5712]Sony NEX-7 (price & specs)[/shoplink], the bottom pic using a [shoplink 2431]Canon EOS 5D Mark III (price & specs)[/shoplink]
As you can see the field of view is as good as identical. Quoting EOSHD: “The Speed Boost effect on aperture is highly evident too. On the NEX 7 the camera reports the maximum aperture as F1.3 and it is certainly brighter. […the] “depth of field is as shallow on the NEX 7 as the 5D Mark III despite the difference in sensor size.“
I agree with the following statement: “This is a groundbreaking product for photographers and cinematographers alike.” The EOSHD post has more samples to check and an exhaustive description on how this wonder thing works.
A synthetic description how the adapter works: “If your sensor is smaller than full frame, shrink the image that the lens throws to fit over it. That is the principal behind the Metabones Speed Booster which essentially gives you the full frame look and a brighter image all at once…“
With this adapter:
A 24mm wide angle like the Canon 24mm F1.4L becomes a 24mm wide angle on the [shoplink 4953]Sony FS100 (price & specs)[/shoplink], with the same shallow DOF and field of view as on the 5D Mark III
A F1.2 aperture on a Canon lens becomes F0.90, a significant 1 stop brighter image in low light
Depth of field becomes shallower – the same as it would be on full frame
