Canon patent for a 58mm f/1.4 lens. It appears 58mm is going to be a new lens category. Is this lens thought to compete with the Nikon 58mm f/1.4?
Canon patent that appears to merge Phase Detect with Light-Field technology to improve auto-focus accuracy.
In current Canon Hybrid AF sensors, Phase Detect AF is used to quickly lock AF and Contrast Detect is employed to accurately set focus. The present patent employs Light-Field technology instead of the Contrast Detect part. That’s a cool trick, since Light-Field allows to set the focus after having shot the photo. If I get the patent right, Phase Detect is used to lock AF, and then Light-Field is used for the fine-tuning. This is not the first Canon patent referring to Light-Field technology (1 | 2). Light-Field technology is featured on Lytro cameras.
Will we see this tech on future Canon sensors? Possibly, the question is when.
Hope I got it right. Canon patent for a buit-in flash that can operate as a bounce flash without popping-out the flash. If you just need the bounce effect, there is no need to pop-out the flash, you just have to rotate the light bulb.
Canon patent for a new lens, an ultra-wide angle and image-stabilised 9-20mm f/4.5-5.6 lens. The described optical formula refers to an APS-C sensor.
Canon patent for a 15-53mm f/2.8-4 lens. Unusual focal range you may wonder. Could this be a patent for a new kit lens? Possibly. It would mean that Canon’s future kit lenses will start at f/2.8. Cool.
Curious Canon patent for a flexible and expandable LCD screen for DSLR and mirrorless cameras. The LCD screen is expanded by rotating a movable grid. According to patent drawings, the technology appears to apply both for DSLRs and compact/mirrorless cameras. The machine translated patent literature seems to suggest that you may have a larger monitor just when you need it.
