A:Answer I'm not sure what other camera and/or lens you are wanting to know the difference between, only one model of camera & lens was mentioned in your question. I will assume you are possibly wanting to know the difference between the Canon T6i with the kit lenses and the Canon T6i with the 18-135 lens....i had another brand dslr with kit lenses......wont do that again. Nothing wrong with kit lenses at all, but if you are trying to progress in your photography they are not a must have, in my opinion. I am able to do so much with my 18-135. It is universal and the only lens I have at this point because it is so functional. Great close ups, nice wider angles, and everything in between!
