dpreview published their review of the Canon EF 200-400mm f/4L IS Extender 1.4x lens. They reviewed the lens together with the folks at DxOMark. Some excerpts from the conclusion:

  • […] it’s clear that the 200-400mm is exceptionally good
  • On full frame it’s near-flawless, and there’s practically no perceptible sharpness penalty for using the extender
  • AF with static subjects is very fast and extremely accurate
  • […] unique among top-end super-telephoto zooms
  • […] absolutely stellar optics and innovative design earn the lens our top award

The EF 200-400mm f/4l IS 1.4x got dpreview’s Gold Award. DxOMark says about the EF 200-400mm f/4L IS 1.4x:

[…] the Canon 200-400mm f/4L IS USM Extender 1.4X offers image quality that’s close to the best in class, along with the convenience and versatility that’s otherwise lacking with those fixed focal length equivalents.

Canon EF-M 11-22mm f/4-5.6 IS STM First Impression (dpreview)

 EF-M 11-22mm

dpreview updated their EF-M 11-22mm f/4-5.6 IS STM first impression review. The 11-22mm is the third lens for the Canon EOS M system, the others being the EF-M 22mm f/2 STM and the EF-M 18-55mm f/3.5-5.6 IS STM. About the EF-M 11-22mm they write:

The EF-M 11-22mm f/4-5.6 IS STM is Canon’s third lens for its mirrorless EOS M camera, and adds a useful wideangle capability in a package that’s impressively compact – especially considering that it’s got optical image stabilisation too. Our initial feeling is that it’s a rather nice little lens that’s pretty well-built, and a good match for the EOS M.

For the time being, the EF-M 11-22mm IS STM lens can be pre-ordered at Amazon Germany and at DigitalRev. You might be interested to check out the performance of the upcoming firmware update (V2) for the Canon EOS M.

Another review that assesses how awesome the SIgma 18-35mm f/1.8 DC HSM lens is. ephotozine reviewed Sigma’s latest addition to their “Art” line-up, and say:

This lens opens new possibilities for owners of APS-C format cameras for low light shooting and creative use of depth of field with a fast f/1.8 maximum aperture, normally reserved for prime focal length lenses. The image quality delivered, especially at shorter focal lengths is of the level normally reserved for prime lenses also.

Jaron Schneider over at fstoppers reviewed the latest addition to Sigma’s “ART” line-up, the awesome Sigma 18-35mm f/1.8 DC HSM lens, the world’s first zoom lens for APS-C DSLRs that has a constant f/1.8 over the zoom range. And at a really competitive price, $799/€999. They used a Canon EOS 60D for the test. Some excerpts from Jaron’s review:

  • […] this lens is beautiful […] a gorgeous blend of metal and rubber with only a few plastic parts
  • […] the autofocus works […] very well in daylight. It’s fast and, generally speaking, very accurate
  • At night, the lens is a bit less accurate, but it correctly focused (in nearly pure darkness) ten out of thirteen times
  • Chromatic aberration is extremely well controlled in this lens
  • Flaring is decently controlled at most apertures
  • […] sharp at all focal lengths and apertures
  • For Sigma’s first run at a previously never before seen lens concept, this is a rousing success.
  • This is so far Sigma’s best APS-C only lens, and it’s the best by leaps and bounds

The following images have been shot using f/7.1, the first at 18mm and the second at 35mm. Click the pics to see them larger.

Video: Canon EOS 10D Exploded View

Matthew Farrell, Michelle Pang, Michael Tom, engineering students of Engineering 128 class from University of California, produced an exploded view (and re-assembling) of a Canon EOS 10D with a 24-85mm F/3.5-4.5 lens to show how complex a digital DSLR is. The video was made 4 years ago. It is not entirely clear if they used blue-prints from Canon but I guess they did the whole modelling on their own. Kudos!

The EOS 10D was introduced February 2003. It had 6.3 MP sensor, a 7-point AF system, magnesium alloy body, ISO 100-1600 (3200), 3fps.

Interesting post by New Zealand based photographer Andrew S. Gibson. The almost 4 years old Canon EOS 7D (price & specs) is still an outstanding DSLR, with an advanced AF system not previously seen on a Canon APS-C sensor DSLR (and still not featured on any other Canon APS-C DSLR). The AF of the EOS 7D is more advanced than the one sported on the EOS 6D. If you want a more sophisticated AF system you have to go at least for the EOS 5D Mark III.
