Lensrentals.com Compares the Canon EF 85mm f/1.4L IS Against the Competition

By Canon Rumors | December 11, 2017 | Canon Reviews

Lensrentals.com has posted a comparison between the EF 85mm f/1.4L IS, EF 85mm f/1.2L and the Sigma 85mm f/1.4 Art. This comparison is not their usual scientific endeavour using OLAF, this is a bit more of a real world comparison by looking at images with our own eyes.

From Lensrentals.com:

The Canon 85mm f1.2L II is the standard and is really middle of the road in this comparison. It’s a great lens with that dreamy bokeh but is the most expensive and is slow to focus. The Canon 85mm f1.4L IS performed amazingly with everything I threw at it. It’s sharper than the 1.2, faster, and has image stabilization but is still pretty expensive. The budget Sigma 85mm f1.4 Art lens is sharp and quick but is really heavy. My new choice to keep in my camera bag for a wedding is definitely going to be the new Canon 85mm f1.4L IS for the image stabilization alone. Read the full comparison

We await full OLAF testing to make sure that the machines agree.

Canon Global Shutter Sensor Paper

Canon Global Shutter Sensor Paper

By Canon Rumors | December 11, 2017 | Canon Cinema EOS Rumors

From Image Sensors World:

MDPI Special Issue on the 2017 International Image Sensor Workshop (IISW) publishes Canon paper “Development of Gentle Slope Light Guide Structure in a 3.4 μm Pixel Pitch Global Shutter CMOS Image Sensor with Multiple Accumulation Shutter Technology” by Hiroshi Sekine, Masahiro Kobayashi, Yusuke Onuki, Kazunari Kawabata, Toshiki Tsuboi, Yasushi Matsuno, Hidekazu Takahashi, Shunsuke Inoue, and Takeshi Ichikawa.

From the paper:

CISs with GS function have generally been inferior to the rolling shutter (RS) CIS in performance, because they have more components. This problem is remarkable in small pixel pitch. The newly developed 3.4 µm pitch GS CIS solves this problem by using multiple accumulation shutter technology and the gentle slope light guide structure. As a result, the developed GS pixel achieves 1.8 e− temporal noise and 16,200 e− full well capacity with charge domain memory in 120 fps operation. The sensitivity and parasitic light sensitivity are 28,000 e−/lx·s and −89 dB, respectively. Moreover, the incident light angle dependence of sensitivity and parasitic light sensitivity are improved by the gentle slope light guide structure.

We’re told that Sigma will be announcing two new 70-200mm lens in the early part of 2018. One of the lenses will be a 70-200mm f/2.8 DG OS Art series lens, and the other a 70-200mm f/4 DG OS contemporary lens.

The 70-200mm f/2.8 DG OS Sport has been rumored for quite some time, but this is the first time we’ve heard about an f/4 contemporary version.

This sort of announcement would make some sense for CP+ in February, I’m not sure CES in January is the place to announce these lenses.

This comes from an unknown source, so treat it accordingly.

Patent: Lots of Big White Lens Patent Applications Surface

Patent: Lots of Big White Lens Patent Applications Surface

By Canon Rumors | December 7, 2017 | Canon Patents

New patents for supertelephoto optical formulas have appeared at the USPTO.

The range of formulas is quite vast, all the way from a new EF 300mm f/2.8L IS to a new EF 800mm f/5.6L IS design.

We do think there will be some new “big white” lenses announced in the next 12 months, not including the EF 600mm f/4 DO IS. We’ve heard from at least one person that Canon may take the EF 200mm f/2L IS back to its f/1.8 roots. Though the latter hasn’t yet been confirmed.

Northlight-Images uncovered a lot of the patent applications, you can view them all here over at the USPTO. [12345]
