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

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.

Full list of affected lenses after the break.

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.

Review – Canon EF 100-400mm f/4.5-5.6L IS II

Review – Canon EF 100-400mm f/4.5-5.6L IS II

By Canon Rumors | June 25, 2015 | Canon Reviews

LensTip has completed their review of the Canon EF 100-400mm f/4.5-5.6L IS II lens. As if we needed more reasons to buy this lens!

From LensTip:

I think those who were waiting patiently for the Canon EF 100–400 mm f/4.5–5.6L IS II USM won’t be disappointed. Its predecessor was optically very good but the new lens is better in every single category. The evenness of performance, no matter what focal length you use and what place of frame you take into account, is truly impressive. The lens remains sharp even on the edge of full frame and doesn’t have any resolution slip-ups. If you add to that the much-improved stabilization, a huge step forward when compared to the older model, you get practically a lens as close to perfection as it is only possible; its flaws, connected to vignetting and flares, aren’t anything serious.

Amazon currently has stock of the EF 100-400mm f/4.5-5.6L IS II lens.
