One look higher than the other, following a hockey fight. My brain corrects this. I wear one contact lens to prescription in my left eye and another weaker in the right eye so I can see far and near. It works seamlessly but does not for everyone. Stranger still, with my right eye to the viewfinder and the left one looking afar I can see a picture in picture with the difference that the small one does not interfere much at all with the larger one.
We will all end up Cyborgs. The whole point about RDSs is to make life easier and I'm still not convinced but if it works for you that good but by trying to use the EVF or LCD simultaneously life just becomes over complicated again.
There aren't really many situations where you can't follow a moving subject so the EVF works fine in most cases and if you do need it such as Vass's Swallows then the RDS comes into play. We dig into the detail The Nikon Z mm F2. With a versatile focal length range and a fast aperture for low light photography and blurry backgrounds, this lens promises sharp imagery and smooth bokeh with minimal aberrations.

If we do not want to understimate the memory needed, and if we want to make a safe estimate in the sense that will almost surely overestimate , it seems that we can put 40 bytes per column plus 8 bytes per cell, then multiply it by a "cushion factor" that it seems to be arround 3 for data copying when tidying, graphing and analysing.
But as we can see in the answers, object sizes vary by type and if the vectors are not made of unique cells they will have smaller sizes, so it seems that this estimate would be really conservative.

Abstract A group performance test of handedness was administered to undergraduates. This test required subjects to place dots in circles as rapidly as possible.
The test was found to be reliable, and to correlate with hand preference. Both hand performance and hand preference measures are skewed in the population as a whole, but the distributions can be adequately fitted by two normal curves, one with a right bias and one with a left bias.
These findings suggest that left-handers are a distinct subgroup of the population.
