As it stands at the moment I have a range of lenses that caters for anything from 12mm to 200mm and I get situations where I could do with a lens that offers more range, for when I'm taking shots at grasstracking, bike racing, music gigs or wild life situations where I can't get really close to the action. My indecision is do I go for the flexibility of the 70-200 with a X1.7 / X2 or do I opt outright for the 300mmm, the other factor is would I notice the difference in quality from the 70-200 to the 18-200 and would the 70-200 just sit in my rucksack
