Canon RF 100-400mm F5.6-8 IS USM Lens Sample Pictures

On this trip, I was primarily testing the new EOS R3 with the Canon RF 600mm F4 L IS USM Lens. However, I had the lightweight, compact, inexpensive Canon RF 100-400mm F5.6-8 IS USM Lens on an EOS R5 readily available in a toploader case, handy to pull out when a wider need arose.

Each morning while heading to the favored deer photography locations, I passed an eastern overlook just before sunrise. A high mountain with no substantial mountains to the east that allows visibility of the sun at a very low angle is a great location to see colorful sunrise. Shenandoah National Park is one such location, and the percentage of photogenic sunrises here is quite high.

On this morning, I simply pulled over, set up the Really Right Stuff Ascend Tripod with the integrated head, mounted the RF 100-400 and R5, and took a few pictures before resuming the deer chase.

As illustrated here, the convenience and utility of the RF 100-400mm lens are very high. The long focal lengths can fill the frame with the color of even a compact sunrise show, and a wide aperture is not important in this case.

With the lens and in-body image stabilization, I could have handheld this shot, but strong winds made the tripod an easier choice for composition and steadiness reasons.

Do you enjoy photographing details? Telephoto zoom lenses are quite adept at this task.

The trees on the top of the mountain range that makes up Shenandoah National Park are loaded with light-colored lichen. I find this look highly attractive, but finding order within the chaos is the big challenge for photographing this subject.

In this case, a tree with red berries stood out among the oak trunks lining the edge of a clearing.

Not everything in a scene needs to be included in the frame. The small berries added a pop of color. Zooming in to nearly fill the frame with the berry tree excluded much of the forest surrounding it and created an interesting pattern of trunks entering the frame.

The Canon RF 100-400mm F5.6-8 IS USM Lens was made for times like this.

This small, light, and affordable lens was ready for use, mounted to a Canon EOS R5 in a toploader case on the seat behind me. This lens's relatively narrow max aperture was wider than needed for this landscape image, and the lens's image stabilization system meant a tripod was not required, despite the strong wind pushing me around.

With the thick layer of duck weed, it seems that the fish and frogs have the advantage in this lake, and the great blur heron hunts on.

The Canon RF 100-400mm F5.6-8 IS USM Lens is a great choice for an affordable wildlife lens.
