Is there time for an interchangeable sensor DSLR?

Re: Is there time for an interchangeable sensor DSLR?

This is reminiscent of Thom Hogan's modular camera obsession. As pointed out above, the machining needs to be precise to allow the sensor to be accurately positioned. And that would greatly increase the cost of the camera, as you have to build a rugged precisely made frame into which you slot the sensor. The sensor also has to be in a frame, to provide strength, and to allow it to mate accurately with the slot. Both are expensive to make, and increase the size of the camera. In addition, the sensor is intimately tied to the image processing chip. So, as well as the sensor frame, and the sensor slot, you have to design a sensor interface, which allows the signals to go from the sensor to the image processor. That further increases cost. You will always be tied to the same image processor too, so if you want to use a sensor with twice the pixel count, you will be limited to the throughput dictated by the current processor. And you will have to upgrade the firmware. Alternatively, you only have one piece of firmware, and then that constrains what you can do. If you want several sets of firmware installed at once, for several sensors, you need more intenal memory, further increasing cost.

In my opinion this just does not fly. It is too niche, and not suitable for a mainstream product.
