I've grown sick of the craptastic image quality on my EF-S 18-200mm IS from Canon and I want to replace it with a higher quality lens. I've narrowed my options to the 17-55mm F/2.8 IS USM or the 24mm-105mmL F/4 IS USM. Most of my photography as of late as been indoors and low light. I do love shooting outdoors but it's too cold right now for me to venture far. The question I'm asking is for anyone who uses a short zoom if you ever miss having the reach beyond 55mm when traveling abroad or for a photosite.
