I guess 'crop factor' is still useful for a lot of people who start with standard full frame 35mm still photography, then move into 35mm movie and other cinematographic formats. If yiu are trying to match the angle of view on the two cameras, pCAM will do a better job. Get pCAM or other similar app like ViewFinder, and you can see the differences between the two cameras directly p, without trying to use a confusing intermediate format. I find crop factors a waste of time, trying to compare a 16:9 or 17:9 Cinema aspect ratio sensor with a still camera 135 sensor, why If you recorded HD physically, you would still see the larger UHD FOV so the crop then is 2x instead of 4x.ĭenny Smith wrote:The BM PCC6K is approximately a APS/C sensor (S35), and the Picket 4K a MFT 16:9 Sensor. You know all this.īut many cameras will downscale in camera so that your field of view uses the full sensor but the image is scaled down by the camera to fit the HD window. If you recorded 1920x1080 HD as a ‘window’ your crop would be roughly 4x compared to 135 film. And this camera can record either 3840x2160 or 1920x1080. The ‘traditional’ Micro Four-Thirds sensor has a physical width of 17.3mm so its horizontal crop compared to ‘full frame’ is roughly 2x let’s pretend the actual photosites available were 3840x2160 UHD. That is often referred to as ‘full frame’ if you are coming to cinematography from a background in photography.ĭigital sensors vary significantly in size and aspect ratio. Let me try to summarize with a simple example.Īny sensor or film gate can be considered a crop compared to the film gate for 135 film (36x24mm). You are asking about this with regard to both the BMPCC6K and BMPCC4K. Stephen, you are close to understanding the options.
