Nikon has filed a patent that makes way for a digital back to convert 35mm film SLRs into the full-fledged DSLRs. The rear door that covers the film holder would be removed and replaced with a digital back equipped with an image sensor.
An excerpt from the patent:
The camera back exchange type camera which images the object image acquired by the photographing optical system by the side of a camera body, and obtains electronic image data is known by replacing with the rear lid with which the camera body was equipped, and equipping a camera body with the camera back having an image sensor.
In the camera back of the description to this Patent document 1, when the moving mechanism to which the position of an image sensor is moved, and the position detection sensor which detects the position of an image sensor are provided and a moving mechanism moves an image sensor based on the output of a position detection sensor, The image sensor to the photographing optical system by the side of a camera body is positioned.

A recent patent publication shows Canon has been looking into adding image stabilization to a 24-70mm f/2.8 lens. Given the recent announcement of the EF 24-70mm f/2.8L II USM lens (which still isn’t available), however, this doesn’t bode well for an IS version anytime soon.
Of course, there’s a Tamron lens that fills this void though…

Canon applied for a patent application on a 70-300mm f/4-5.6 lens in March 2011. Presumably, this is an update to the consumer grade line of 75-300mm non-IS lenses. There’s no mention of image stabilization in the patent; however, that doesn’t necessarily mean that it couldn’t be an IS lens.
These are the current consumer zoom models in this range:
The other line of thought is that a new 70-300mm f/4-5.6 lens with image stabilization could replace the existing mid-grade lens as a cheaper/lower model. [click to continue…]
