@toysoldier Thanks Martin - I used a 70 - 200mm f2.8 Canon lens,which is worth every (and there were many!) cent I paid for it! It's a nice all rounder and if I put a converter on it I lose very little speed and quality, and have a more powerful telephoto as well.
@24atlantic Thx for the feedback, I kind of thought it might be the 70-200mm. That baby is at the top of my wishlist! Your work really justifies the price and I look forward to see what you produce next :)
