I know a lot of people who do not understand the importance of a good quality lens.
This 18-200 worked fine with the 7D and was OK for travelling light. With the 7D2 - not that much. For this occasion I was purposefully shooting with the crappy lens, just for fun. I have seen a photo series where a photographer used a 100+ year old camera and took pictures of a Formula One race. That reminded and inspired me that the photographer is more important then the gear.
