It is a great lens for everyday use… extremely wide at 24mm, it is great for landscape shots, as well as the portrait shots I take. For portraits, my favorite focal length is around 85mm to 90mm or so.
The resulting images have been amazingly sharp and I am happy with my decision of upgrading to a full frame Canon camera.
When the upgraded 5D Mark IV was announced in Aug 2016, Canon also announced an upgrade of the kit lens to Canon 24-105 F/4L IS II.
However I got to buy the older and lighter 24-105mm F4L IS, as it is only 670grams (23.6oz). The newer 24-105 IS II in comparison is 795grams (28.1oz).
Previously I had used the Canon 100mm F/2.8L lens on my 80D for macro shots, but I could not use the lens much, as it used to become 160mm on the 80D’s APS-C Crop sensor. It was too much zoom for me and so I was disappointed because of the slightest amount of camera shake would blur.
However, on a couple of occasions I removed the 24-105mm and tried the 100mm lens on the 5D Mark IV, and it was extremely usable and amazingly sharp for macro shots, as the magnification is a full 1.0, even with hand holding the camera.
But I put back the 24-105mm back on because I use it as a walkabout everyday lens, and the great focal length variation makes it a wonderful & versatile choice. I wouldn’t want to do macro with the 24-105 because the magnification factor is only 0.23x.
However , the macro feature works perfectly fine to do close ups or shoot flowers and butterflies at close range.
The build and optical quality of this Canon all rounder is marvelous. It is weather sealed, light enough to carry around. It does not extend when zoomed, unlike most lenses ( all other lenses extend when zoomed; so far I have seen only the 24-70mm F/2.8L which for some reason extends the other way when zoomed).
I’d recommend to put a UV filter to be more safe, as I don’t like my lens exposed!
The 77mm filter makes it easy to share filters among other Full Frame lenses, but I’d suggest to keep an inexpensive UV filter on at all times.
This lens renders pretty true colors and the contrast is very accurate.
The Image Stabilization (IS) feature of this lens makes it easy to hold the camera in my hands and still shoot at a very slow shutter speed, without getting any blur.
It allows for up to 3 stops slower, which is pretty amazing. Previously I’d be scared to attempt any hand held below 1/60, but now I have tried 1/15 a few times, hand-held, and I got all shots quite sharp, even in low light conditions.
