As we know that Canon has released its newest lens, RF Lens. RF lenses have a lot of series. One of them is Canon RF 24-105mm f / 4L IS USM. Canon RF 24-105mm f / 4L IS USM is the first kit lens to be introduced for EOS R. This lens is specifically designed to suit Canon EOS R and EOS RP mirrorless cameras. This lens is a generalist lens in many ways.

Focus range works well for landscape photography, portraiture, journalistic photos, travel photography, and many other genres. Interestingly, the price is identical to the Canon EF 24-105mm f / 4 USM L IS USM. For this reason, in this article we will discuss the features in this lens. The following features the Canon EF 24-105mm f / 4 USM L IS USM.

Canon RF Body 24-105mm f / 4L IS USM

This lens is made to high standards with the barrel of a polycarbonate lens and internal seal against dust and water. The optical design consists of 18 elements in 14 groups, including three aspheric elements and one glass element UD. The Canon EF 24-105mm f / 4 USM L IS USM body is relatively light. This is because this lens follows the Canon L. design philosophy. The Canon EF 24-105mm f / 4 USM L IS USM also has a weather sealing feature.

Measuring 83.5 mm in diameter and 107.3 mm in length (at 24mm settings), the 24-105mm f / 4 RF is relatively compact for a full frame zoom lens. Compared to the Canon EF 24-105mm f / 4L IS USM II, the mirrorless version has the same diameter, but shorter 10.7 mm. The weight is also less than 95 grams, which is 700 g compared to 795 g.

AF system

The next feature in the Canon EF 24-105mm f / 4 USM L IS is the AF system. The AF system on this lens uses the Canon “Nano” Ultrofocus Motor. By using the Nano, this lens has a very fast even by DSLR standards and is also silent. In addition, this lens is also accurate in taking objects. The Canon EF 24-105mm f / 4 USM L IS has a minimum focal distance of 0.45m. Canon claims that it provides the equivalent of 5 f-stops, a valuable feature considering that the EOS R and EOS RP do not have in-body image stabilization. Manual focusing works with wire and the best in class is as far as accuracy.

Control Ring

This lens is also equipped with an additional control ring on the front of the lens. The new Control Ring is a distinctive feature of any Canon RF lens. This can be used to adjust various settings. Including aperture, ISO, and exposure compensation. If you are worried about errors turning the wrong ring, it can be set only to adjust this setting when pressing the Meter button. Petal lens hoods are also provided. In addition, the focus control ring operates smoothly.

The zoom ring is just behind the manual focus, but it is tapered so that your fingertips don’t confuse them. And besides sitting on the front of the lens, the Control ring has a diamond-shaped footprint so you can’t think of it for anything else.

Fringing at both ends of the focus range is clearly visible on the edge of the frame, but does not mean disturbing. Sticking to more focal lengths and deviations are well controlled, especially at 70mm.

Canon RF 24-105mm f / 4L IS USM has two switches on the left side of the lens barrel. The first is a simple AF / MF switch, while the second is the On / Off switch for the Image Stabilization system in the lens. On the right side of the barrel is the zoom lock button that I mentioned earlier.


Lens distortion with all corrections inside the camera is deactivated to fully expose optical weakness. As a result the lens does show a small barrel distortion at 24mm, a fast transition to the same level of pining pads at 50mm and so on.
