Rumor: Canon EF 100-400mm f/4.5-5.6L IS Replacement Set to be Announced Soon?

EF 100-400mm

 

It appears as if Canon might soon announce a new EF 100-400mm lens. The production of the EF 100-400mm f/4.5-5.6L IS may be “coming to an end soon”. The new 100-400mm should go into production at the end of 2013 or beginning of 2014. The rumor also suggests that Canon will not starting production of the new 100-400mm until the production figures for the EF 200-400 f/4L IS 1.4x (Amazon | Adorama | B&H) are not in line with demand.

Thanks Mark. lenstip published a long interview with the optical engineer that designed the outstanding Sigma 35mm f/1.4 DG HSM (price & specs) and Sigma 18-35mm f/1.8 DC HSM (price & specs) lenses. The interview comes with lots of b&w images that appear to represent Sigma’s laboratories. Some excerpts from the interview:

Q:What is more important today: intuition and experience or an access to new software and fast computers
A: We think that both are important. Although it is necessary to use machines perfectly, we cannot come up with creative ideas if we rely too much on technologies. Sometimes it is necessary to advance it with own judgment while considering about the purpose and results at all times.

[...]

Q:At what point do you start thinking about the usage of antireflection coatings? Does an optics specialist think of them already at the beginning of their work or do they just optimize the final product according to the elements used in the construction or their refraction coefficient?
A: We start thinking about the usage of antireflection coatings from the middle stage of the design.

[...]

Q:In the case of such a unique construction as the Sigma 18-35 mm f/1.8 which parameter was set as the first? The focal range? The aperture? Or perhaps the image quality was the main priority and you adjusted the rest of parameters accordingly?
A: The project had started with a lens incorporating a maximum aperture of F1.8 and 2x zoom-ratio lens with a focal length equivalent to 50mm in a 35mm format. After some speculation, we decided to produce the 18-35mm f/1.8 lens because it seemed to be able to achieve the highest performance with this spec.

That’s what a poll by diyphotography has revealed, 1000 people gave their vote. More than 60% of the voters want better low light performance, approx. 20% wishes a better focusing, and just 1.42% want more Megapixels. Surprised? The poll was started in this post, check the comment section for more discussion.

Zeiss Close To Announce New High End Lenses (first lens is a 55mm f/1.4)

Zeiss

Zeiss (nowadays without the “Carl”) revealed plans for those lenses some time ago. The first lens they are going to release – in Autumn 2013 – is a 55mm f/1.4. The new lenses will embrace a new design philosophy that Zeiss exposed in an article titled From brand personality definition to prize-winning design. Prototypes were shown at Photokina 2012. They write:

The project had been discussed internally at ZEISS for a long time. The first concepts were already discussed in 2008, but it was not until 2010 that things became concrete. Back then it was clear to the experts at ZEISS that the image sensors in the new generations of cameras would make such a big leap forward that there would already be a need for corresponding high-performance lenses in the medium term. [...]  ZEISS wanted to offer photographers a range of high-end SLR lenses that would enable them to use the full potential of such cameras. Such a combination would achieve performance values that would be comparable to those of medium-format systems.

“When the 1,4/55 comes onto the market at the end of 2013 as the first in this family of lenses, it will be one of the best lenses in the world,” summarizes [the project manager]. “There will be nothing of comparable quality, and that not only applies to this specific focal length range.  With this product ZEISS has truly opened up a new dimension of digital full-frame photography.”

Canon EOS 70D Auto-Focus Tests (Viewfinder & Live View with various lenses)

YouTube user Daero Lee posted a series of videos that show how the Canon EOS 70D‘s auto-focus works (and performs). Most videos tackle the Dual Pixel CMOS AF, but there are also some that show a view through the viewfinder, and how the AF performs. More videos after the break.
