user14588: 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?

user12233: For high zoom, low light you need all these things.

Large sensor.
Long lens [not software zoom].
Large aperture.
High ISO capability with low self-noise.

This is not a cheap combination, by any stretch of the imagination.
I would very, very much doubt any 'camcorder' can do all the above. I don't know of any camcorder with a large sensor at all. They sacrifice sensor size because it's factors easier & cheaper to make a long-throw lens for a tiny sensor.
I could suggest a good combination, but you'd need a spare $£€ 50,000 in your sock drawer.
