I’ve had a random finding a couple times now while shooting with the EOS R while it’s snowing.  It seems to want to focus on the snow, or more really the snow pulls the focus away from the subject, and it has to work harder to keep focused on what I want focus on.

EOS R + 400 f/2.8L II @ ISO 3200

It is crazy how drastically it impacted my “hit ratio” of sharp shots when it’s snowing versus not snowing, it’s like I went from not missing a shot, to having a ratio of 50% if it started snowing.  In Yellowstone, I started making the decision to switch to the 5D Mark IV if it was snowing out.

I tried to switch to different AF Area modes to see whether there was a difference between single point, expanded point, etc., but I did not see an improvement, and as the point got bigger it seemed like it was jumping off the subject more, which makes sense.   Next time we get a good snowfall around here, I am going to go out with a stationary subject and see what they hit ratio is.

I saw that Canon is intending to put out a new firmware for the EOS R, and while the details of the update have not been disclosed I’m curious whether or not this will be addressed.

I’m curious how this finding will be impacted by heavy rain that sometimes occur on our coastal trips, and whether this camera will essentially be unusable in these situations. I will keep testing and playing around with it, and keep you updated on what I find.  Feel free to contact me with any questions [email protected].
