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.

The Canon EF 35mm f/1.4L II “Done” [CR2]

The Canon EF 35mm f/1.4L II “Done” [CR2]

By Canon Rumors | June 25, 2015 | Canon Lens Rumors

We’re told that the Canon EF 35mm f/1.4L II is “done” and ready for production. An announcement date is unknown as Canon is still playing catch-up on some other in demand lenses such as the EF 100-400mm f/4.5-5.6L IS II.

SPECIFICATIONS

  • Dust & Weather Sealing
  • All the latest coatings
  • Longer than the current version
  • Smaller diameter than the current version
  • Smaller filter thread
  • New hood design
  • Unknown weight

I think a fall announcement is likely, and I don’t expect such a lens to be announced alongside a camera body.

On a side note. I’m heading to Chicago this weekend and will be using the current EF 35mm f/1.4L exclusively on the EOS 5DS.

Review – Sigma 50mm f/1.4 DG HSM Art

Review – Sigma 50mm f/1.4 DG HSM Art

By Canon Rumors | June 24, 2015 | Canon Reviews

Dustin has completed his review of the Sigma 50mm f/1.4 DG HSM Art for Canon Rumors. This follows the other 50mm offerings from both Zeiss and Canon.

Dustin came away impressed with the Sigma offering, but had the same concerns as others when it came to autofocus performance. However, the other 50mm offerings out there aren’t perfect either. The Zeiss Otus doesn’t have AF and the Canon 50mm f/1.2L can suffer from focus shift which is very frustrating for some photographers.

All in all, Sigma has made a major breakthrough in creating a large aperture prime with world class optics that is in a price range that most professional and many amateur photographers can afford. While the stated “target” is the Zeiss Otus, there will actually be fairly few photographers that are cross-shopping these two lenses. The Otus is still the optical king (and this goes beyond chart testing) and enjoys a certain cache that Sigma can’t touch. But the Sigma is a far more practical lens for most photographers, as most photographers need autofocus for their work.
