I've probably purchased a Canon 24-105 F4 L IS Lens a dozen times. This series of lenses, including the Canon RF 24-105mm F4 L IS USM Lens, Canon EF 24-105mm f/4L IS II USM Lens, and Canon EF 24-105mm f/4L IS USM Lens, are professional-grade, high-performing, relatively compact and lightweight, and affordable. That combination, along with the versatile 24-105mm focal length range, make these lenses ideal for many uses, including family, travel, and hiking.
So, why do I keep rebuying them, aside from the new models becoming available? Well, I try to keep the kit trimmed to the gear that is most important to me. I sometimes shoot moving subjects in low light, such as at indoor events, and in these scenarios, an aperture wider than f/4 is desired. Thus, there is always a 24-70mm F2.8 L lens in the kit.
With a significant general-purpose focal length range covered, it seems that 24-70mm lens should be adequate for all needs. When there is some time space since the last 24-105 F4 need, the 24-105 gets sold to finance seemingly more important needs.
Then, a need arises that reminds me that I really do need that lens, usually for its size, weight, and focal length range, and I re-buy it. And, the story repeats – more often than it should.
The second Canon RF 24-105mm F4 L IS USM Lens arrived in my kit earlier this year. With some long hikes on the schedule, the need for this lens again became apparent. I bought it to keep this time (unless I forget the reasons again), and it performed impressively.
One location that the RF 24-105 was perfect for was Badlands National Park.
Few elements make a prairie more photogenic than a good storm with a rainbow, and the first thing I grab when a rainbow shows up is a Breakthrough Photography circular polarizer filter.
