I rarely used my sigma 10-20mm, so I shouldn't have bothered getting a 17-40mm but I did. Then I thought about how much I had tied up in a rarely used lens and figured I could use the money on something I would use more often. So I sold it and don't regret it. I don't shoot for paid gigs so no need to keep it.
I am considering just ditching the EFS 10-22 without adding a 17-40L, too. We have a trip scheduled to the Smoky Mountains and western North Carolina, and I will be making an effort to try and use the 10-22. If it still doesn't get used, then selling it, along with the 50 1.4 and 85 1.8 would fund a 50L.
