I've heard that cheaper lenses can cause pixel death to occur near the corners of the sensor (not enough light coming in to keep the pixels healthy) and this causes vignetting over time. Is that where crop sensors come from (full frame sensors with dead-pixels cropped off)?

I've heard of crop sensors that are haunted with the ghosts of lenses past -- it's disturbing, I tell you. Tony

Canon don't take a 35mm FF sensor and take a pair of scissors to it. Never heard about pixel death though - not sure it makes sense, otherwise the sensor would die off when the camera is turned off...

Interesting theory. Time in our universe would have to be reversed for this to occur. In our time line, the crops came first. In a parallel or alternate universe, full frame sensors appeared initially and through something akin to evolution became the crop. Perhaps these crops learned to travel between universes and became trapped in ours. They found we liked them and they slowly and expensively evolved into full frame sensors.

Is that where crop sensors come from (full frame sensors with dead-pixels cropped off)? To keep the corner pixels healthy, you would need a center spot mask, black of course. Then point the camera sensor at the sun with spf40 until you smell a bit of burning. The edge pixels should be properly revived with a healthy tan. Enjoy!
