That’s great! The 24-105mm f/4 is my go-to walk-around lens with full frame. 🙂
In addition to having a mid-range lens like the 24-105mm, I would highly suggest getting a good wide-angle lens to take advantage of the fact that you have full frame. I used the 17-40mm f/4 for a long time, until I was able to save up for (or more like, get a good deal on) a 16-35mm f/2.8. This is hands down my favorite lens.
You could also go wider, with true EF lenses that let you go out to 14mm or 11mm, but then you start to get some seriously noticeable fisheye distortion.
And not to confuse things, but if I understand @creative-click-photography’s question correctly (“What is 105 equivalent to on a crop sensor?”), @ernestf-lloyd first answer was actually correct (“a focal length equivalent to 38-168mm”). Here’s why:
The Tamron SP 17-50mm f/2.8
* True focal length (if used on a full frame sensor): 17-50mm
* Effective focal length (since it’s being used on a cropped sensor; what you’re used to): 27.2-80mm
* Like @dfrazer said, “A 24-70 or something similar” is what you would be used to
Canon EF 24-105mm f/4L IS II USM
* True focal length (if used on a full frame sensor): 24-105mm
* Effective focal length (if used on a cropped sensor): 38.4-168mm
* In other words, 105mm on a full frame is equivalent to 168mm on a crop sensor, which was @ernestf-lloyd’s first answer
Since you’re used to seeing 27.2mm when using a 17mm lens on a cropped sensor, you will see pretty much the same thing now (24mm) when using a 24mm lens on a full frame sensor.
And so you can figure out all this with any lens, to arrive at an “effective focal length”, just multiply the true focal length by 1.6 (for most situations). Regardless of whether or not the lens is designed for a full frame camera or cropped sensor camera, it will always be labeled with the true focal length.
