So I've begun shopping around for those industry cctv lenses and I have noticed that they are generally made for 2/3" sensors with the odd 1" sensor.
Obviously I'd want to go for the larger one but just curious as to what were the sensor sizes for those old 16mm cmount lenses that everyone is using...1"? Just wanted to confirm.
I currently have a 25mm Avenir cctv lens made for 1"sensors and there appears to be no signs of vignetting. There is a 12.5mm also made for 1" sensors. I would assume the image circle will stay the same offering a good alternative for a fast 12.5mm wide lens? Am I to assuming wrong because people say if you go lower than 25mm it then doesn't cover the sensor anymore which I find strange because if it was made to cover a 1" sensor it would always cover it if you know what i mean? i dunno. crazy aussie talking.
cheers.
