That's my first post here. I've discovered nikoncafe just recently and am very excited about joining the communinity of fellow nikonians! I have just paid for a 600VR (expect to receive it soon) and plan on getting 300VR or 200-400vr (have not decided yet, and this is going to be a separate thread I guess :smile So I am going to need a bag that would nest both lenses and at the same time meet the carry-on requiment of most of the carriers. I have done some research and found Thinktank Airport International™ V2.0 http://www.thinktankphoto.com/ttp_product_ArprtInl2.php, which is very good based on a review here http://www.luminous-landscape.com/reviews/accessories/international.shtml. The only potential issue is whether it will really fit two big lenses. Based on the internal sizes stated by the manufacturer it will barely fit 600VR + 300VR + D3. Going for а bag of the next size gets me out of carry-on requirements. When you travel with 600mm plus another big telephoto lense : what bag are you using for your air travel? Is there a solution ? Thanks in advance.
