Canon EOS 1DX MK3 Auto Focus Results in Winter Blizzard

Late yesterday I wrapped up my 2020 expedition to photograph Arctic Fox in the Hornstrandir Nature reserve in the north-west of Iceland. This year we had an absolute abundance of snow and some fantastic conditions (full trip report coming soon) with strong winds that created a really dramatic environment for photography. The conditions this year were in fact the best I can recall in recent years. Next years expedition is a couple of weeks earlier than this year which should promise similar conditions with deep, soft snow that makes for superb backgrounds for this tenacious little predator.

This years expedition was also the first chance for me to truly test the Canon EOS 1DX MK3’s auto focus system in the field (in winter). Conditions were absolutely ideal for testing this past week with strong wind and blizzard conditions that were perfect for torture testing the cameras autofocus. Visibility was often near zero and the air was literally full of blowing snow. During our shooting sessions we had to frequently clean the front lens elements from blowing snow. With temperatures hovering around -6º Celsius the cameras were frequently covered in snow and frozen. Despite the difficult conditions the 1DX MK3 auto focus proved truly superb. I was consistently and reliably able to obtain focus lock and tracking in white out blizzard conditions where focus would previously have been all but impossible (or at best extremely unreliable). The new tracking system (when set to Case 2 for these type of conditions) provided an extremely high keeper rate; even in the heaviest blowing snow blizzard conditions. I doubt there could have been more difficult conditions for any camera to auto focus and in comparisons between my own findings and those shooting Sony A9 MKII cameras we found the results comparable in terms of the cameras ability to lock and track focus. If there are any differences between either cameras ability to lock and track focus in these sort of conditions they are a quibble. The differences however between the 1DX MK3 and other DSLR cameras ability to lock and track focus are huge. The 1DX MK3 represents nothing short a significant quantum leap in auto focus capability for DSLR cameras. Of course, you can also lock up the mirror on the 1DX MK3 and expand the focus points further and add eye tracking on top of head tracking for even better performance. The video below gives you some idea of the conditions I was testing the cameras autofocus.
