Egami (translated) spotted a Canon patent concerning a second row of electronic contacts on the lens mount. The patent suggests the second row of contacts is dedicated to the video signal, avoiding loss of signal strength could be the reason (the video signal needs more power supply).

A Bit Of Everything (Sigma 35mm f/1.4, Canon In East Africa, And More)

Sigma 35mm f/1.4

Two new Sigma 35mm f/1.4 DG HSM reviews for you. The terrific Sigma 35mm f/1.4 (price & specs), part of Sigma’s “Art” line-up, is getting a lot of positive feedbacks from photographers and reviewers.

Cameralabs writes in their verdict:

The Sigma 35/1.4 DG HSM is a very exciting lens. You can produce shots with image quality you might think were impossible at a wide open aperture of f1.4. Plus the build-quality and the new design support Sigma’s claim to have developed and manufactured a lens to professional standards.

The pros of the Sigma, according to cameralabs:

Outstanding performance in the corners of a high-resolution full-frame sensor even wide open.
Good build quality.
Quiet and fast AF operation.
Relatively low price compared to the big names.

Next, photographer Justin Wojtczak of 375photography.com (source: fstoppers) made a video-review of the lens.

Generic tidbits…:

  • The regional arm of Japanese firm Canon Inc that is banking on new office to oversee seven African countries will strengthen its position across the rapidly growing markets of eastern Africa.
  • Having a dedicated entity in Kenya is meant to further reinforce the company’s ‘closer to customer’ strategy and offer enhanced support services to partners and customers across East Africa,
  • Canon Kenya will provide marketing and channel development services in Kenya, Ethiopia, Tanzania, Uganda, Somalia, Eritrea, Rwanda and Burundi.

 

Have a nice day….

Happy Birthday Ansel Adams

Ansel Adams

Well, it’s not Canon related, but I hope you appreciate.

Today is Ansel Adam’s birthday, he would turn 111 years old if he were still alive today. Quoting The Huffington Post:

Adams began his career as a photographer in the early 20th century selling snapshots of Yosemite National Park. Obsessed with fine-tuning his craft, the San Francisco-born artist was known to dabble in everything from soft-focus imagery to etching before settling on a photographic style marked by sharp contrast and intense exposures. Over the course of his 60-year career, he worked closely with fellow photographers Fred Archer and Alfred Stieglitz, showed his work at a major retrospective at the Metropolitan Museum of Art, and helped to found the major photography magazine, Aperture.

Canon Product Advisory For Speedlite AF Assist Beam Issue on EOS 5D Mark III and EOS -1D X

Speedlite AF assist beam

Ok, Canon reacted to the problem of the auto-focus beam issue observed using Speedlite AF assist beam with a Canon EOS 5D Mark III (price & specs) or Canon EOS-1D X (price & specs). Everything started when a user posted about the problem in the Canon USA EOS forum, getting the following answer from a forum moderator (I reported about this here):

Canon has confirmed that, depending upon the shooting conditions, it may take slightly longer for the EOS 5D Mark III and EOS-1D X digital SLR cameras to acquire focus when using the Speedlite’s AF Assist Beam, compared with that of the EOS 5D Mark II and EOS-1D Mark IV digital SLR cameras using the Speedlite’s AF Assist Beam. We are developing a firmware update to enhance the focusing feature for the EOS 5D Mark III and the EOS-1D X. The schedule for release of this firmware update will be announced shortly.

Yesterday Canon USA released the following product advisory:
