I have a Canon 5D Mark ii with the 24-105L lens and wonder if it makes sense to get a 2X extender for my trip to Spain. I also have an older Canon 75-300 lens but don't want to carry both. Concerned about quality with the extender and also whether a good one exists that fits my camera. (Thanks, Canon...) Also considered a used Canon 55-200, but Rockwell said that my camera couldn't handle the color problems.
Appreciate your help and snark,

The 24-105mm lens cannot be used with an extender. The Canon extender protrudes into the rear of the lens and will not physically mount to the 24-105.
