I would like to record sport events happening in the evening. This would be recorded from static points, around 150 m from where the sporting people move.
I'm choosing the camcorders for this. What technical parameters should I pay attention to?
I've tried a few. They are excellent at a shorter distance, but as the zoom increases, the image becomes blurry and/or grainy - even in a direct sunlight from the right direction.
I have read some theory about how camcorders work, and it seems to be a physical phenomenon, going to the quantum nature of light. It improves with the size of the sensor and the camera lenses. But the zoom cameras tend to have rather smaller sensors.
What qualities should I prioritize to have a decent FHD picture?
