EOS R5 How to have all photos at 3:2

[Zhaopian]

Hi,

I have an EOS R5. How do I change the settings to have all photos taken in 3:2 size not full frame? I do see a means to resize one image at a time, but I really don't want to do that.

Is aspect ratio, resize, and crop really all the same thing? I want to make sure I'm looking at the right function in the settings.

Thanks

By default the EOS R5 shoots still images in the 3:2 aspect ratio. 8192 x 5464 pixels is the exact pixel resolution and that is as close to 3:2 as anything. 

If you choose the 1.6x crop on the camera it uses a smaller section at the centre of the image, but still a 3:2 aspect ratio. Lastly there are cropping information options in the custom settings. These result in lines appearing in the EVF and on the LCD to indicate where the aspect ratio is applied. Images are not actually cropped, but data is added to the metadata so that Canon and some other software shows them as cropped images, but the crop can be released.

You are correct that when one sets the camera to save a raw CR3 file that only the 1.6x mode discards some of the data recorded by the sensor.

3:2, 6:4, 9:6 are all the same aspect ratio. width by height

6000x4000 pixels is 3:2 aspect ratio. 8192x5464 pixels is 3:2 aspect ratio. 5088x3392 pixels is 3:2 aspect ratio.

The largest number of pixels that the EOS R5 can record is 8192x5464 and is 3:2 aspect ratio. All of the other aspect ratios record fewer pixels. The other aspect ratios crop (discard) some of the pixels. Resizing does not necessarily discard pixel information, but may average it or interpolate it. I suggest using the Canon DPP program for resizing or cropping. However, I often use the 1.6x crop on my EOS R5 because it seems to improve eye tracking auto focus when a small bird is far away.

Your question does not make sense - for reasons the others have pointed out. Why not explain *exactly* what you are trying to do.
