Canon

CanonUSA promotional video highlights the capabilities of Canon’s specialised CMOS sensors.

The video below showcases Canon’s variety of sensors. For several decades Canon has been developing and manufacturing advanced CMOS sensors with state-of-the-art technologies for exclusive use in Canon products. These sensors are a critical driving force behind many of our successful product lines, ranging from consumer products all the way up to high-end business and industrial solutions. These Canon sensors are of the kind featured on the Canon ME20F-SH, a specialised, multipurpose camera system. If you’re curious to learn more about these Canon sensors click here.

Canon’s sensors are so good you can capture a rainbow under moonlight. Watch to see.

Cinematographer/filmmaker Ivo Norenberg approached Canon in 2010 with a request for an extreme lens. He challenged Canon to produce a long zoom 4K Super 35mm lens tailored to the diverse needs of wildlife video production.

The Canon 35MMFHDXS CMOS sensor is a high sensitivity and low-noise champion

Canon 35MMFHDXS

Here is another sensor prototype from Canon. The Canon 35MMFHDXS CMOS sensor was recently presented along with other prototypes The sensors are a 120 Megapixel CMOS Sensor, a 5 Megapixel Global Shutter CMOS, and the 35MMFHDXS, 19μm Full HD CMOS Sensor. If you’re curious to learn more click here.

The 35MMFHDXS CMOS sensor delivers high-sensitivity, low-noise imaging performance, enabling the capture of Full HD video even in exceptionally low-light environments. The sensor’s pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases. High sensitivity and increased well depth have been achieved through a larger pixel size of 19μm x 19μm (square) with proprietary device design technologies. The 35MMFHDXS CMOS sensor is available in RGB, RGB+IR or Monochrome.

The Canon 120MXS 120MP CMOS Sensor delivers spectacular performance

Canon 120MXS

Canon 120MXS 120MP CMOS Sensor

Back in January, at CES 2018, Canon gave some insights in their R&D labs. Three sensors were presented.

The sensors are a 120 Megapixel CMOS Sensor, a 5 Megapixel Global Shutter CMOS, and a 19μm Full HD CMOS Sensor. If you’re curious to learn more click here.

The Canon 120MXS sensor, with a 120MP resolution shows what Canon is capable of. This kind of sensor can be used for many applications, surveillance, scientific experiments, medical etc. For a mirrorless camera too, I guess. It’s APS-H format.

The 120MXS is an ultra-high resolution CMOS sensor with 13280 x 9184 effective pixels(approx. 60x the resolution of Full HD). It has a size equivalent to APS-H (29.22mm x 20.20mm), and a square pixel arrangement of 2.2µm x 2.2µm with 122 million effective pixels. Ultra-high-resolution is made possible by parallel signal processing, which reads signals at high speed from multiple pixels. All pixel progressive reading of 9.4fps is made possible by 28 digital signal output channels. It is available in RGB or with twice the sensitivity, in monochrome.

The video below gives you a good idea what you can do with this sensor.

Canon EF 85mm f/1.4L IS developers talk about the craft behind the lens

EF 85mm F/1.4L IS

The Canon EF 85mm f/1.4L IS is in stock and sells for $1,599 at Amazon (world wide), Adorama, Canon Store, and B&H Photo.

Canon Europe posted an interview with the engineers who conceived and designed what is universally seen as the most exciting Canon lens of 2017, and as another optical masterpiece by Canon. The interview appears to be a slightly modified version of an interview posted December 2017 on Canon Asia’s Snapshot site (with more sample images).

The interview starts with Mr. Yamaguchi, Canon’s Product Planning Lead, next is Mr. Iwamoto, Canon’s Optical Design Lead, and finally Mr. Okuda, Canon’s Mechanical Design Lead.

Excerpt from the interview with Mr. Yamaguchi:

During the planning of the EF 85mm f/1.4L IS USM, we talked with many professional photographers, including wedding photographers, who would have many opportunities to use this lens. They told us that EF 85mm f/1.2L II USM is highly valued for its excellent expression and bokeh thanks to its large aperture. Being a heavy lens, however, it’s easy to get tired with extended use, and the autofocus speed is not necessarily satisfactory. Some said that even though it’s a large aperture single focal length lens, the addition of image stabilisation would allow worry-free shooting.

Excerpt from the interview with Mr. Iwamoto:

We focused on striking a balance between clarity of resolution for the centre of the screen that’s a feature of an L lens and the beautiful bokeh on the edges, ideal for popular portrait compositions with subjects in the centre of the frame, while taking realistic weight, size and cost into consideration.

[…]

In order to reduce the size of the entire lens, both the focus group and stabilising optical system must be lightweight and only move a small amount. For this lens, we used the following new optical arrangement from the front of the lens: the front group, the focus group, the diaphragm, the stabilisation optical system and the rear group.

Excerpt from the interview with Mr. Okuda:

Using highly durable ball bearings in the drive mechanism for this lens reduces load and improves resolution and accuracy. The use of ball bearings also contributes to high-speed autofocus. The heavy focus lens group must be driven with the limited power of the motor, but the focus lens can be driven quickly since the ball bearings reduce the load.

The interview comes with a lot of very interesting images of the interiors of the EF 85mm f/1.4L IS. Definitely worth to read. Read Canon Europe’s article “The craft behind the Canon EF 85mm f/1.4L IS USM lens“.
