Specifically 5D IV vs. R6 with the same lens. R6 images are ~17% smaller. Why?
The images were taken minutes apart.Have you taken the pictures at the same time? The distance moon earth changes and the moon sometimes apears larger.
Please elaborate - you're saying 100% magnification is 87% magnification with R6 images?I assume you are looking at them with the same magnification. If you use 1-1 (pixel peeping), then the difference in megapixels is what you are seeing. If you are viewing the images with fit to screen, then the framing should roughly be the same.
Imagine you have an 8K monitor, meaning a ~33 MP display. An image from your 5DIV at 1:1 would nearly fill the screen. The same image from your R6 at 1:1 would not nearly fill the screen, so the image displayed will look smaller. The same is true at 1:1 on a lower resolution display, but you only see part of the image.Please elaborate - you're saying 100% magnification is 87% magnification with R6 images?
Essentially, yes (although I haven't done the maths to check the difference is 17%).Please elaborate - you're saying 100% magnification is 87% magnification with R6 images?
