Andre Yabiku – Seeking the next meal – Shot with G1X
Thomas Emberson – Near the end of last summer, this (the exposures) was shot with a 7D, 10-22mm lens at 22mm, ISO160. The arch is from the Marget Hunt Hill bridge in Dallas, about 30-45 minutes after sunrise.
Egami (translated) spotted a patent filed by Canon for a new sensor technology that expands the dynamic range of the sensor with a thin polysilicon layer applied on top of the photodiode layer of a sensor.
As far as I understand the patent, the polysilicon layer’s thickness is not the same for all the underlaying photodiodes. This influences the sensitivity of the photodiodes through the transmittance of light, which is attenuated by the film according to its thickness. The result are pixels (=photodiodes) with different light sensitivity.
Looking at the image above, it seems that there is one pixel with a thicker layer for each pixel with a thinner layer. The layer thickness appears to act on the the exact area where the photodiode detects the incoming photons.
An interesting patent that points to a new sensor technology. Hard to say if this tech will show up soon, for instance in the again rumored high megapixel cameras expected for 2015.The technology described in the patent does not refer to a given class of sensors, nor to a sensor size. It’s a technology that could find its way in any future Canon sensor.
Canon sensors are often critiqued for having a dynamic range below the competition, and thus getting lower DxOMark scores for their sensors. It appears Canon is going to address the issue.
Machine translated patent description:
- Patent Publication No. 2014-175553
- Published 2014.9.22
- Filing date 2013.3.11
- Canon patent
- Optical attenuation film is arranged by polysilicon over the photoelectric conversion portion
- Transmittance of light depends on the optical attenuation film is its thickness, thickness varies depending on the pixel
- Small pixel transmittance is, the opening area is small
- RGB any of the color filter
- Transmittance R <G <B
Two Black Friday killer deals for the Canon EOS 6D are still live:

- HOT: Canon EOS 6D bundled with PIXMA Pro-100 photo printer, paper etc for just $1,249 after $650 mail-in rebate (instructions), by authorised Canon dealer B&H Photo (limited time)
Need a lens for your 6D? Adorama has refurbished Canon EF 24-105mm f/4L IS lenses for ridiculous $599.99 on eBay.
All Black Friday listings, lot of deals are still there and many are very good (5D3, 70D, T5, lenses, etc).
Photozone analysed Canon’s new pancake lens for APS-C cameras. The EF-S 24mm f/2.8 STM has more to offer than the low price might suggest. The only weak point of the lens is vignetting.
From the conclusion:
[…] nothing wrong with the optical performance of the new Canon EF-S 24mm f/2.8 STM. This is especially true for the bitingly sharp center but even the border and corner quality is on a very high level straight from f/2.8. The low amount of lateral CAs contributes to the very high sharpness perception. The barrel distortion is low and rarely an issue. On the downside, the lens produces a rather massive amount of light falloff at max. aperture but stopping down to f/4 solves most of the issue already.
A lens with good build quality that offers a lot of bang for the bucks. Photozone gave the EF-S 24mm f/2.8 STM a “highly recommended”.
