In S007, the camera CPU 302 changes the image recording range for the obtained image to the range in which the light is not shielded by the tilt-shift operation. ….the camera CPU 302 generates a signal to reduce an image pickup area of the image sensor 301 so as to make available the tilt-shift by the tilt-shift unit, when the image size of the interchangeable lens 100 is equal to the sensor size of the image sensor 301. Here’s how the patent application explains the process: This just accepts the fact that the image circle is going to be reduced and relies on the high resolution image sensor to accommodate the smaller image circle. Automatic In-Camera Cropping for Tilt-Shift OperationĪdditionally, based on what is revealed in the patent application, Canon is using cropping on the sensor in order to fit the tilt-shift images into a native camera format. The adapter can process the image preview information based on the camera sensor format and the reduced image circle to limit the amount of shift or tilt so that the image is not cut off from the sensor.

But it works hand-in-hand with the Canon EOS body and EF lenses to not only serve as a pass-through for communication but to also take on some processing burdens to make tilt-shift work on different cameras and lenses. Additionally, there are motorized drivers inside of the adapter that can drive the shift and tilt axes using controls on the camera (or the adapter itself). You might think Canon would have used an image enlarger inside the adapter to increase the image circle size but Canon went a different route entirely.įirst off, the Canon Tilt-Shift Adapter has its own CPU inside and no optics. Just really smart engineering using tech in a different manner than which is was originally purposed. Canon’s Tilt-Shift Adapter DesignĬanon’s method of getting around the tilt-shift conundrum using standard lenses with standard image circles on a full frame or APS-C camera makes me smile.

That’s a lot of work and probably one of the reasons they aren’t very popular. Second, you have to go up in format size, which means you are using medium format lenses on Canon DSLRs.
#Tiltshift canon manual#
First, they are completely manual and transmit no electronic info between the lens and body. You can buy tilt-shift adapters for Canon mounts now however, there are a couple of key limitations. Read on for how it works and why it’s so cool. In a recent patent application submitted to the USPTO, Canon revealed a new adapter under development that would essentially turn every Canon EF lens into a tilt-shift lens.
