Seeing as how the sensor crops the image when using a non-digital lens it seems logical, just wondering if anyone has any definite answer.
No the images on the sensor are still the same size ratio 1:4. The only thing is the image is croped. 35mm film is 35mm wide so with a 1.5 crop factor the sensor size is 23mm, and other way of looking at it is: 50mm lense on a camera with a 1.5 crop factor is equivalant to a 75mm lense with the same field of veiw that you would get if you installed a 75mm lense on a 35mm film camera like a Nifon F series or any other brand of 35mm film camera.
