The Canon EF 35mm f/1.4L II leaked a few days ago, and we are pretty sure it will be announced August 14 along with the EF-M 15-45mm IS STM.

CR got a tip from a retailer, suggesting the price for the new 35mm f/1.4L II will be $1,699. That’s all for the time being. No specs or other information regarding the lens.

No Canon EOS 5D Mark IV coming, but Canon EOS 5D X and EOS 5D Xs? [CW3]

EOS 5D Mark IVQuestionMark2
A Canon EOS 5D Mark IV rumor was posted to the DPReview forum. Quoting:

Just got off the phone.. Looks like Canon is to name the 5D Mark IV 5DX. 28 megapixels, Digic 6+-basically a souped up version of 6 just to name a few.

X branded bodies will be for event and sports photography. S will be for studio, landscape, etc

We were first to post a rumor suggesting a model split for the EOS 5D Mark III replacement. Not just one EOS 5D Mark IV model, but two models with different specialisations. Our rumor suggested an EOS 5D Mark IV and Mark IVc naming scheme. The “c” pointing to a more video-oriented model.

The new rumor seems to refer to EOS 5D X and EOS 5D Xs (or “X S”) monikers. There are some things that make sense here. The number “four” is seen as a sign for bad luck in Japan (and Asian culture). Avoiding it in a naming scheme wouldn’t be that strange after all. However, Canon made the EOS 1D Mark IV before releasing the EOS 1D X as its replacement. Using the number “four” in the naming doesn’t seem to be a big issue for Canon. The EOS 1D X is also considered the replacement for the EOS 1Ds Mark III. Using an “s” in a camera model naming isn’t something Canon started to do with the EOS 5Ds and EOS 5Ds R.

Following the rumor, the EOS 5D X might be considered the “straight” update to the EOS 5D Mark III, the EOS 5D Mark Xs a more studio-oriented model. The former being the replacement for the all-rounder the EOS 5D Mark III is, the latter being the specialised model. Nothing new about the few mentioned specs. 28MP sensor, new DIGIC processor. Consistent with past rumors.

How to relate all this to the persistent rumors about a Canon 18MP full-frame sensor in the works? Here things get complicated. I can’t really figure out that the EOS 5D Xs (i.e. the studio-oriented model) will have 18MP. On the other hand, I doubt that 18MP will be featured on Canon’s all-rounder model, the supposed EOS 5D X, given that the EOS 5D Mark III has 22MP. If this 18MP sensor exists and is part of some plans Canon have, then most likely such a sensor is going to be featured on a video-oriented DSLR. A new Canon DSLR that could also have 4k, one of the rumored features of the EOS 5D Mark III successor.

It’s hard to rate a rumor posted in a forum. Given some consistency with earlier rumors, I give it a CW3. All EOS 5D Mark IV rumors are listed here.

Curious to know what you think about all this. Feel free to let me know in the comment section.

Sigma 24-35mm f/2 DG HSM price announced, available for pre-order ($999, coming late July)

Sigma 24-35mm f/2

  • EF Mount Lens/Full Frame Format
  • Aperture Range: f/2 to 16
  • FLD & Special Low Dispersion Elements
  • Two Aspherical Elements
  • Super Multi-Layer Coating
  • Hyper Sonic AF Motor
  • Internal Focus; Manual Focus Override
  • Rounded 9-Blade Diaphragm
  • Thermally Stable Composite Material
  • Compatible with Sigma USB Dock

Sigma announced price and availability of the Sigma 24-35mm f/2 DG HSM lens, the world’s fastest full-frame zoom lens, and the first with constant f/2. The price is $999, availability expected for late July.

You can already pre-order the Sigma 24-35mm f/2: Adorama and B&H Photo.

RONKONKOMA, N.Y. Sigma Corporation of America, a leading DSLR lens and camera manufacturer, today announced that the new Sigma 24-35mm F2 DG HSM Art lens will become available in late July for the street price of $999.

The 24-35mm F2 DG HSM Art lens is the market’s first full-frame zoom that allows photographers to carry one fast aperture lens that can do the work of three popular fixed focal length lenses – the 24mm, 28mm and 35mm. It includes an optimized autofocus (AF) algorithm for smooth, fast, and accurate focusing, a manual focus (MF) override functionality, and is made of Thermally Stable Composite (TSC) reducing its size and weight.

Built upon the impressive versatility offered by Sigma’s 18-35mm F1.8 DC HSM Art lens, the new 24-35mm continues the Art line tradition of top optical performance that’s comparable to Sigma’s 24mm F1.4 DG HSM Art and 35mm F1.4 DG HSM Art. It offers optimized lens power distribution, and minimizes spherical aberration, axial chromatic aberration and field curvature. The Sigma 24-35mm F2 DG HSM Art lens also features a video-friendly, inner focusing system that eliminates front-lens rotation, enhancing the lens’ stability as well as a Hyper Sonic Motor (HSM) that ensures a silent, high-speed AF function.

“The combination of fast, constant aperture and zoom versatility will make this lens exceptionally popular for photographers who crave the convenience of wide angle zooms, paired with the performance of fast, wide primes,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The Art lenses have raised the bar for total imaging performance, and this lens is going to make a lot of photographers very happy.”

As with all new lenses under the Global Vision categories, every 24-35mm will be tested using Sigma’s own modulation transfer function (MTF) measuring system, “A1,” in the company’s factory in Japan. It is compatible with Sigma’s USB DOCK, which allows photographers to update the lens’ firmware, adjust focus points and customize full-time MF function settings by using Sigma’s Optimization Pro software. Sigma’s exclusive Mount Conversion Service, which enables users to easily convert the lens’ camera mount between supported versions, is also available for a fee. The lens will be available in Sigma, Canon and Nikon mounts.

The Sigma 24-35mm F2 DG HSM Art lens will also feature:

  • Large-diameter, aspherical lens elements, which require advanced technologies to produce, one “F” Low Dispersion (FLD) glass, and seven Special Low Dispersion (SLD) glass elements with two aspherical lenses. The advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration and field curvature, resulting in outstanding optical performance
  • A video-friendly, inner focusing system that eliminates front-lens rotation, enhancing the lens’ stability and allowing use of circular polarizing filters
  • A Hyper Sonic Motor (HSM) that ensures a silent, high-speed AF function. Smoother AF is achieved when the this AF algorithm is optimized
  • Full-time MF by rotating the focus ring of the lens while auto focusing
  • A nine-blade, rounded diaphragm creates an attractive blur to the out-of-focus areas of the image
  • Specifications: Lens construction containing 18 elements in 13 groups; a weight of 33.2 ounces; a diameter and length of 3.4 inches by 4.8 inches, respectively; a minimum aperture of F16; and angle of view (35mm) of 84.1° to 63.4°; minimum focusing distance of 11 inches; and a maximum magnification ratio of 1:4.4
