Tamron Product Advisory for Canon EOS 5DS and EOS 5DS R

By Canon Rumors | June 30, 2015 | Third Party Lenses

A notice regarding compatibility issues with the EOS 5Ds and the EOS 5DsR, and availability of firmware update service (JUNE 2015)

Dear users and potential purchasers of Tamron interchangeable lenses for Canon.
Thank you for being a valued customer of Tamron products.

We have learned that the AF functions of the following interchangeable lenses for Canon do not function in Live View mode when used on the EOS 5Ds and EOS 5DsR  which went on sale in June 2015.

We sincerely apologize to all users and potential purchasers for any inconvenience the issue may cause.

Firmware update service is already available as this is the same case when EOS Rebel T6s and the EOS Rebel T6i were released.  Also, Model A011 with the latest firmware for panning shot treatment is compatible and functions properly with these new cameras.

The full list of affected lenses is after the break.

Sigma Product Advisory for EOS 5DS and EOS 5DS R

By Canon Rumors | June 30, 2015 | Third Party Lenses

Sigma issued a service notice (from Sigma Japan) regarding a Live View issue withthe Canon EOS 5DS and EOS 5DS R camera bodies and some Sigma zoom lenses.

Phenomenon
When the Live View Mode button on the camera body is pressed, the operation stops without displaying images on the rear LCD monitor.

More Information

  • If your lens was updated to be compatible with the EOS 760D / 750D, then it will also work with the 5DS / 5DS R. Otherwise you will have to send it to Sigma for a free firmware update.
  • Lenses shipped after May 11, 2015, already have the new firmware and will work in Live View with any current Canon DSLR.
  • Users of the 120-300mm f/2.8 DG OS HSM Sports – the only Global Vision lens to be affected by this issue, see list below – can do this at home using the USB Dock and Sigma Optimization Pro.

Did Sigma Beat Canon to an f/2 Zoom? [CR1]

Did Sigma Beat Canon to an f/2 Zoom? [CR1]

By Canon Rumors | June 28, 2015 | Canon Lens Rumors

We’re told that Sigma may have beaten Canon to the market with an f/2 zoom for full frame cameras.

We’ve been told over the years that Canon was working on a zoom lens faster than f/2.8, but nothing had ever come of it. We’re now being told that Canon has been working on a wide angle L zoom lens which is “faster than f/2.8″, but the exact speed could not be confirmed.

I’ve never doubted that Canon has been trying such a thing, they’re making a lot of “look-what-we-can-do” lenses, such as the EF 8-15 f/4L fisheye, EF 200-400 f/4L IS 1.4x, TS-E 17mm f/4L and the EF 11-24mm f/4L.

Canon won’t be constrained from a marketing standpoint when it comes to pricing for such a lens, so they may be able to make something a bit more versatile than Sigma. Although, usability, size and weight cannot be ignored in such a lens design.
