The Problem: In recent times, I have both recorded podcasts and blogged about the ongoing difficulties of photographing in heavy snowfall with mirrorless cameras. Mirrorless cameras (regardless of brand) have a tendency to move between the falling snow and the subject, with an inability to lock onto the subject without distraction. This can be incredibly frustrating as the focus bounces between the subject and falling snowflakes, resulting in missed shots. As a polar photographer who frequently shoots in snowfall, I have been continually frustrated by this phenomenon and have witnessed it among other photographers using everything from Canon and Nikon to Sony mirrorless cameras.

The Technology: In Canon cameras, the EOS 1DX MK3 was the king at ignoring falling snow and staying on target. Mirrorless cameras such as the EOS R1 are a different beast, though, and use different AF technologies (phase detect) that are highly tuned by manufacturers to be as sensitive as possible. This results in better AF performance overall. But it also means the focus points are more likely to latch onto extraneous objects or subjects, such as falling snow.
The Customisation: I have tried tweaking the various autofocus settings in both the Canon EOS R1 and EOS R3 to ignore falling snow, with only mixed results. In the EOS R1, there are three AF adjustment options: Auto, Manual, and Special. Most of the time, I just leave the AF set to Auto, and it does a superb job. I have played extensively with the Manual setting in falling snow and tried all the different combinations for sensitivity and tracking, with nothing but mixed results and no combination that reliably ignores falling snow.

The Solution: During my recent Svalbard ship expedition, I had a bit of a light bulb aha! moment one evening when I was unable to sleep. Laying in bed and pondering the problem (my head is obviously a scary place to be) What about the Special setting? The Special setting is designed specifically for sports photographers shooting through Soccer nets behind the goal, and it had never occurred to me to even try this in falling snow. But the more I pondered it, the more I realised there are a lot of similarities, as both situations require the photographer to shoot ‘through’ something. The following morning, I jumped online and read up on the Special setting in the Canon Auto Focus Guide found HERE.


The Special Setting: There is some key wording above that reads: “This setting tends to focus on the background more than other options.” This made me super curious and eager to try how the Special setting performed when photographing wildlife in heavy snow. Fortuitously, a couple of days later, I got my chance and switched my EOS R1 to the Special setting with the RF 600mm f4L IS USM lens and an RF 1.4TC when photographing Walrus in heavy snowfall.

The Results: Fully expecting to encounter the exact same problem of the focus bouncing between the subject and falling snow, I was absolutely ecstatic when the EOS R1 locked onto the Walrus and remained locked on – completely ignoring the falling snow! Over the next ten minutes, I took over 300 photographs of the Walrus, losing focus only when the subject became obscured by ice. Using such a long combination of focal length of the 600mm F4 with the 1.4 TC (effective focal length 840mm) ensured that there was a lot of falling snow between the camera and subject making this an ideal test.
Further Testing Required: The above is an isolated example; further field testing is required to ensure ongoing, predictable, and repeatable results. However, the initial results from using the Special case setting in heavy snowfall are extremely encouraging and give me real hope that this may be the ideal solution for snowfall situations. Unfortunately, I am now headed back to Australia for three months and will not have an opportunity to shoot in the snow until later in the year. If you are shooting an EOS R1 and have a chance to test this yourself in snowfall, please let me know how you find the Special case performs. There may be a strong case for Canon to change the wording of this to “Case Special”. Characteristics suitable for shooting through Nets and Snow.
