I have the Canon SL1 with the standard 18-55mm lens. Taking a trip to Switzerland in the summer and really want to start amping up my skills and get off auto mode! I'm looking at getting the 24-105mm f/4 L lens and didn't see a set for that one. I am going to purchase the 18-55mm set. Any chance you have something that would work for that lens as well, or do you have recommendations on a better lens? Looking for something good for travel/landscape/nature but also good all around. Many thanks!
