24-70mm f/2.8 lenses are the workhorses of choice for a huge range of photographers and filmmakers, as they offer a very versatile focal length range in tandem with a wide maximum aperture. Nonetheless, not everyone needs that f/2.8 aperture, and if you are willing to exchange that for f/4, you can get even more focal length range at a reduced price. For Canon shooters, one such lens is the RF 24-105mm f/4L IS USM, and this great video review takes a look at the performance and image quality you can expect from it in practice.
Coming to you from Dustin Abbott, this excellent video review takes a look at the Canon RF 24-105mm f/4L IS USM lens. I owned the first version of the EF mount version of this lens for a long time, and it was by far my favorite and most versatile walkaround lens. I have always found 70mm to be just a little short, while I really do not need that f/2.8 aperture when traveling or just going for a hike. And with the high-ISO capabilities of modern cameras, that f/4 aperture is even less of a problem for most applications. On top of that, the 24-105mm f/4 is about half the price of the 24-70mm f/2.8. Check out the video above for Abbott's full thoughts on the lens.
