It's nearly holiday time again, and I'm having to think about which Lenses to take with me.

I have discounted the Sigma 30mm as it's not really that versatile to justify carrying it. That leaves the 14-42mm, the 40-150mm and the 70-300mm.

For weight and convenience I'm tempted with just the two kit lenses. However, it would be a great opportunity to give the 70-300mm a decent work out. However, I 'm nor sure I could fit it in my small camera bag, and I don't think my crumpler will fit inside the carry on luggage I'm planning to take.

Would I miss the gap between 42mm and 70mm if I took the 70-300mm?

I can't justify using up one hand luggage item with just a camera bag as we have a 2yo daughter who needs quite a bit of luggage space for all her toys/milk, food, books etc.

Do you think the kit zooms are a good compromise; after all it will give me 28-300mm equivalent in a lightweight package.
