The RF 24-105mm f/4L has optical image stabilization built in, and it works quite well. Canon rates the IS to around 5 stops of stabilization, and I’ve generally gotten between 4 and 5 stops of shake reduction when using it on the EOS R and EOS RP. This allows for shots of around 1/6-1/4 second at 105mm, which is excellent.
At review time, the Canon RF 24-105mm F4 L IS USM Lens is probably the next most-considered RF lens for travel and general-purpose use. The focal length range comparison is not close with the 24-240 obviously having a huge advantage. The 24-105 has a fixed f/4 max aperture to its advantage.
The new EF 24-105mm f/3.5-5.6 IS STM is Canon’s smart answer to this issue – an affordable standard zoom that makes the step up to full frame a little less painful. Nothing comes for free, of course, so inevitably this is not as well specified when compared with the existing EF 24-105mm f/4L IS USM lens.
Maybe in 2014 Canon might release the 24-105mm f/2.8 IS. it was a result of a defective "Power Aperture Diaphragm Shutter Unit For Canon 24-105MM F/4L IS USM"
