I appreciate the feedback so far, Gents. I realize that "walk-around" was a little vague. My previous 70-200f4l IS was on my 5DII at least 95% of the time. I guess you could say my "vision" of what I like to shoot leans way more towards telephoto than medium or wide. I enjoy taking zoo picture with the family, but also shots on my motorcycle touring of my buddies riding towards me, my dogs running towards me, etc. The tele lens comes in very handy for those kind of shots.
There is not a doubt in my mind that if I got the 70-200 or 70-300, it would be on my camera far more than an ultra-wide would. If only the decision were that simple. Because as has been said, I can't duplicate an ultra-wide shot with the 24-105, but I can, to some extent, take shots that I would with a 70-200.
Hi!
Hmmm... decisions, decisions...
Here's what I'd do, and what I typically do. I'd write down a list of the candidate lenses, and how I'd use them. Also, I'd write the prices and other relevant characteristics. Where would you use the 18? Where would you use a 300mm focal length? Yes, to some degree you have decent reach with the 24-105, and you can crop to "zoom". At 300mm, you can crop to zoom even more. Do you need f/4 all the way to 200, or can you get by with f/5.6 at longer focal lengths? I actually use a mind map to collect and review information as it is easier to manipulate than a list, but you could do a list (on a computer or by paper and pen/pencil) and that would work. Also note strengths and shortcomings you find in reviews you trust. What tradeoffs are acceptable? Which are not? Usually for me, one lens will stand out.
All that said, from what you have indicated, you would really use a 70-200 or -300. I have both the 24-105 f/4L IS and the 70-200 f/4L IS, and use them all the time on my 5DM3. I also have a Sigma 12-24mm f/4.5-5.6. In the last month I was looking for a sports lens and examined the 70-200 f/2.8L non-IS and IS, the 70-300 f/4-5.6L, and the two 100-400mm f/4.5-5.6 offerings, Mk I and II.
I love my 70-200. It is sharp and sufficiently fast to shoot sports. It doesn't have a long reach, but it is good. But then you already know how well it works. When I was looking for a sports lens, a review of the 70-300 indicated the IQ at long focal lengths wasn't as good as it might be. Still, it may be sufficient for your needs. On wide angle, I don't use my 12-24 a lot and when I do it spends a fair amount of time at 24mm, but there are times when only wide angle will do.
I just did a bit of checking. My lens use is as such across almost 35,000 photos, based on counts through Lightroom:
24-105: 53%
70-200: 42%
12-24: 5%
How would I vote? I'd go for the 70-200. It's a solid lens that has excellent IQ, and I'd take that over the extra reach of the 70-300. Additionally, I'd use the 70-200 far more than the 18mm, though I'd keep it in the queue as a next lens.
Hope this helps!
