Interesting comparative review of three Canon 55-250mm lenses by dicahub (translated). The EF-S 55-250mm f/4-5.6 IS vs the EF-S 55-250mm f/4-5.6 IS II vs the new EF-S 55-250mm f/4-5.6 IS STM. The comparison is based on specs, never the less it gives a good overview about features. Head over to dicahub for the spec overview.

A short video by dpreview where they test and show the Dual Pixel CMOS AF of Canon’s new EOS 70D. About the Canon EOS 70D they say:
It’s become increasingly rare for any manufacturer to show us technology that’s genuinely innovative and unique, but that’s exactly what Canon has done with the EOS 70D and its ‘Dual Pixel CMOS AF’ sensor.
dpreview added a “user experience” section to their preview, be sure to check it out: there are more videos and impressions. Original video files can be downloaded.
More AF test videos at salon.web, sample shots (also high ISO) at Digital Life Innovator # and Digital Life Innovator #2 and Digital Life Innovator #3 and more samples and videos.
Canerastuffreview reviewed the Canon EF 200-400mm f/4L IS 1.4x lens and once more the outstanding properties of this not so cheap lens are confirmed. They conclude:
The Canon 200-400 mm performed in our test with the highest image quality we have come across for a Canon zoom lens, with and without the 1.4x converter. Flare and ghosts are incredibly well suppressed and in terms of resolution, the camera is likely to be the limiting factor. Professional sports, action, or nature photographers will quickly be convinced of the qualities of the Canon 200-400 mm f/4 with built-in 1.4x converter. Compared to lenses with a fixed focal length, the zoom range of 200 mm to 400 mm zoom delivers an excellent opportunity to frame precisely, while the picture quality remains high.
The sensational built-in converter prevents the laborious procedure of inserting a converter between a camera more than a kilo and a lens of more than 3 kilos. It prevents the frustration of missing just the right shot, because you were inserting a converter between the lens and the camera. The fact that under damp and dusty conditions you need to change the lens as little as possible is also important in order to maintain the highest image quality.
There is much more in the review, as sharpness comparison at different focal lengths, analysis of distortion, vignetting, resolution, center sharpness vs corner sharpness etc.

A comparison between the Canon 24-70 f/2.8L II USM and the Tamron 24-70 f/2.8 VC USD. The former a $2300 lens, the latter a $1300 lens. Both definitely worth to be compared. Matthew Gore (from lightandmatter) examines the differances betwen the Tamron 24-70 f/2.8 VC USD and the or the Canon 24-70 f/2.8L II USM in this well made 14 minutes video. He concludes that the Canon is a bit sharper, on the other hand the Tamron has image stabilization. Gore’s description:
[via lensvid]Curious whether the Tamron or the Canon 24-70 f/2.8 is right for you? This comparison might help. I take a look at the image quality of the lenses, including a look at the chromatic aberrations, and the sound and speed of the focusing motors.
