I have a Canon 24-70 f2.8L which I think is a great lens but I find it a bit heavy to carry around, and there are times when I would like something either a bit wider or a bit longer.
So I'm thinking of selling the the 24-70 and buying a 17-40 f4L for something a bit wider, and a 24-105 f4L for a lighter walk around lens with a bit more length and IS as a bonus. From the posts I've read it appears that the 24-105 is a good lens and for me it seems to tick a few boxes.
But I'm not so sure about the 17-40 because I don't know how much difference there is between the two lens at their widest. Is the difference between 17 and 24mm like "wow, look at that", or "hmmm, is that it?".
