Can anyone explain why a camera with a 1/1.8" sensor can have a F stop of 1.6 while a camera with a sensor of 1/2.7" can have a F stop of 1.0?
Camera CMOS size vs F stop.

The 1/1.8" sensor is larger than the 1/2.7" so it needs less light and can get by with a smaller aperture (higher F-stop number); the 1/2.7" sensor is smaller so it needs more light, hence the larger aperture (smaller F-stop).
The higher F-stop of the larger sensor also provides greater depth of field, thus a sharper background.

F-stop is the ratio of focal length to used lens diameter. And you can have an f-stop of 1.0 with a camera having an 1/1.8" sensor. Got two of them here. You can have 1.0 with a 1/1.2" sensor. They even made them for the 36mmx24mm classic film SLR sensor. It is just the question if you are willing to pay the price for this. And I don't just mean money. A wide open lens will give you a brighter but otherwise worse image. Everything has a price. So a 1.0 lens is a specialized lens, which you would want to avoid, unless you require the specialty.

Hello, good morning.

Is there a such thing as a camera system that is not complete trash? Suggestions?
Pardon if I seem frustrated, but I grow tired of wasting money and more importantly time. . . . First system was a Lorex setup which has always been absolute garbage. Everything about the experience has been terrible. Their support I thought was the worst, but atleast I could get them on the...
