Canon EOS R5 and RF 70-200mm F4 L IS Lens Running with the Big Dogs
Let me introduce you to "Nala," my oldest daughter's year-old goldendoodle. I was looking for a subject to challenge the new Canon RF 70-200mm F4 L IS USM Lens for the review, and Nala happily volunteered. She maintained a great spirit for 25 minutes until the session ended abruptly when another dog arrived.
Not long ago, capturing an eye-sharp image of a big dog in a great pose while running (bouncing) full speed toward and close to the camera was extremely challenging. With the Canon EOS R5's incredible animal eye AF combined with the 20 fps frame rate and the Canon RF 70-200mm F4 L IS USM Lens in front of it, the biggest challenge of this shoot was deciding which of the 1,400+ images on the ProGrade Digital 325GB CFexpress 2.0 Cobalt Memory Card to keep.
Bright white snow is a strong auto-exposure influencer, typically causing the camera to underexpose images. With bright white snow filling greatly differing percentages of the frame during each dog pass, exposure compensation was not optimal. Thus, my most frequently used exposure mode, manual, was the ideal choice.
This shoot's goal was to challenge the camera and lens AF system, so the shallow depth of field provided by a wide-open aperture was best, providing little margin for error. The wide-open aperture in combination with the longest focal length provided the strongest background blur possible, making the subject stand out.
Next, the shutter speed was selected, with freezing motion the goal. I opted for 1/1250-1/1600, choices that proved marginally short enough for this fast dog in some instances.
ISO was the last image brightness factor to be applied. As a rule, snow in the sun should be nearly blown-out white. To determine the optimal brightness, the histogram is the proper tool. The ISO setting was increased until the brightest pixels were registering nearly against histogram graph's right side. Note that the blinkies will likely show before color channel capacities are reached. Use the histogram.
This day was cloudy, and cloudy skies often bring brightness changes. Thus, the histogram required monitoring for ISO adjustment needs.
With the R5 in face and eye detection mode and animal eye AF selected, the remaining job was to keep the dog in the frame while holding down the shutter release as my daughter repeatedly positioned and ran Nala toward the camera.
With the R5 and a good lens, getting the perfect action shots is (often) only a small challenge.

Canon RF 70-200mm F4 L IS USM Lens and The Lone Oak Tree in the Snow
A few months ago, I noticed a large oak tree standing alone at the top of a field in the countryside not far from home. I made a mental note of the interesting tree, keeping that photo opportunity in the pocket for later application.
Right after a recent snowstorm and during the Canon RF 70-200mm F4 L IS USM Lens review seemed like the perfect timing to photograph this lone tree. The snow minimalized the scene's details, and the lens was a perfect choice to capture it. I pulled the SUV into a snowbank to get out of traffic (there was little on this country road), turned off the vehicle (eliminating the vibration), and photographed the tree until I couldn't think of any more compositions to try and adding any more insurance shots seemed complete overkill.
This scene was filled with bright subjects. At most, changes in lighting through the thick clouds happened slowly. Thus, a manual exposure that pushed the histogram graph to the right edge proved perfect. In this image, ISO 100 provides low noise, f/8 yielded adequate depth of field, and 1/160 with image stabilization activated made getting sharp elbow-rested photos easy.
The focal lengths in the 70-200mm range are among my most used for landscape photography. These focal lengths provide angles of view that make good compositions easy to find. While parked along this road, I used all of these focal lengths, with the tree filling various percentages of the frame, ranging from the 70mm result shared here to the tree nearly filling the frame. An example of the 70-200mm focal length range using this tree is shared in the Canon RF 70-200mm F4 L IS USM Lens review.
I shoot a lot of action and other images where timing is critical to get the perfect shot, with a stress-induced adrenaline rush typically accompanying the moment. A nice change for this image was that I had as much time as I cared to take. The tree was not moving, the snow was not melting, and the clouds were unchanging.
At the longer focal lengths, not much time was needed to get the good compositions. At the wider focal lengths, there was considerably more freedom to position the tree in the minimalistic scene within the frame. My favorite tree position at 70mm is shared here, but I also like the tree toward the upper left, and the tree centered at the bottom in a vertical orientation also looks great (at my wife's request, I ordered a metal print of that image this morning).
