I shoot weddings. When I was shooting weedings with the XTi and Tamron 17-50, I was very pleased with the results but when I upgraded to the 24-105 I saw that my shots were overall sharper. I would shoot the tamron at f4.0 with flash and I would shoot the canon at f4.5 with flash and IS off. Always on tripod.


I did run into issues with 24 not being wide enough so I would have to switch to my tamron.


I purchased the 24-105 and then later another 24-105 as a kit lens with my 5D. I now wish I had originally purchased the 24-75 f2.8 so now I would have both. Hindsite is always 20/20.
