I'm in the market for a longer lens for my Canon 7D. My focus is primarily wild life and outdoors and I currently have an 18-200, I'm debating between a Canon EF 300mm f/4L IS USM with an extender and a Canon EF 100-400mm f/4.5-5.6L USM. I like the idea of working with a prime lens, but I'm not sure if the versatility of the 100-400 is greater than having a fairly long prime lens...what are your thoughts?
Thanks
