Canon Patent: Image Stabilized Lens For Astro-Photography

Canon Patent

Egami (translated) spotted a Canon patent concerning an image stabilized lens for astro-photography. The lens is able to automatically track objects (stars etc). Canon has a DSLR suited for astro-photography, the EOS 60Da (price & specs). Such a lens obviously needs a camera that supports it. That means GPS, levelling, and a powerful CPU.

Canon Rumor: A Large Sensor PowerShot Camera Coming In 2013

Canon Rumor

A new, interesting rumor came up. Canon may be working on a compact camera with a large sensor. Not a successor of the PowerShot G1 X (price & specs), but a camera like the PowerShot S110 (price & specs), just a bit a larger. The camera should have a fast lens and the new APS-C 18MP sensor featured on the Rebel Sl1/EOS 100D (price & specs), and the DIGIC 6 Image Processing Unit. No viewfinder. Pricing should be less than the PowerShot G1 X when it was released. We expect Canon to announce this camera at the end of SUmmer 2013.
