Telephoto lenses are excellent choices for filling the frame with the color of a sunrise or sunset.
The Canon RF 70-200mm F2.8 L IS USM Lens was the choice for this morning.
It's a superb lens.
At least that is the lens I originally thought I captured this image with.
I later realized that the EXIF indicated the Canon RF 24-70mm F2.8 L IS USM Lens was the lens responsible for this image.
The two lenses are interchangeable at this focal length.
