That explains why they cost so much.

I think they reduced the number of internal lenses with the latest Series II models which made them lighter on the hand but heavier on the pocket.

My 400mm is currently resting up in it's hermetically sealed coffin for the week ahead.

I think the most part is the 1000 pond per KG for the lens glass

I did add a link to the longest canon lens ....
