Canon has patented multiple products in recent times, includes an EF-S 10-22mm f/3.5-4.5 lens that features a built-in liquid element.
Digital imaging manufacturers have been criticized quite often for the lack of innovation in recent times. Although Sony and Sigma are both launching interesting devices, Canon and Nikon have fallen down the pecking order when it comes to new and exciting products.
It appears that Canon is listening to its critics, as the Japan-based company has just patented a really weird product. It consists of a 10-22mm f/3.5-4.5 lens that employs a liquid element.
Canon EF-S 10-22mm f/3.5-4.5 lens patent describes an optic with a liquid element
At first sight, there is nothing unusual about this patent. However, upon closer inspection, this optic is not like others. One way or another, Canon has managed to put a liquid element into a lens aimed at APS-C-sized DSLR cameras.
Although it is very unlikely that this product will be released anytime soon, the Canon EF-S 10-22mm f/3.5-4.5 lens patent has the role of reminding us that things we deemed as impossible are possible. The manufacturer should probably focus on this product instead of the recent “See Impossible”
The optic will offers a 35mm focal length equivalent of 16-35mm. As stated above, do not hold your breath over the launch of this lens, but do not rule out any possibilities for the distant future.
New patent allows Canon cameras to choose the best photos from a burst mode batch
Another interesting patent from Canon consists of a special algorithm. A camera’s burst mode is useful when photographing high-speed subjects, but lots of users still have trouble sorting the photos or choosing the best one.
The EOS camera maker is aiming to fix this problem using an algorithm that will be able to determine which is the best photo when shooting in continuous mode.
After selecting the best shot, the camera will save the file in RAW format, while all other shots will be saved in JPEG format in order to preserve precious space on your SD card.
Nevertheless, users can still choose to save even the “worst” shots in RAW as well as the best shots in JPEG.
Canon patents EF 2x teleconverter
Finally, Canon has patented an EF-mount 2x teleconverter that comes with an integrated Diffractive Optics element.
The company has some lenses that use DO elements in order to reduce the size and weight of the product, while improving image quality.
Teleconverters are already pretty small, so this is probably an attempt to raise the quality of the TC. This could actually make it to the market soon, therefore you should stick around to find out more!
