...And in regard to earlier discussion re 50 mm lens for me to take away to HOST exhibition. I was travelling light and almost 100% work rather than play, and decided to take only the one lens. The lens worked out perfect. It just took me a couple of days to get used to it. The stands for the most part are huge (not the bog standard 3m x 3m stands you see at local shows). The BFC stand was probably 15 m x 10m and there were plenty bigger as well as a bit smaller. No probs maneovering around subjects with the 50 mm lens. But I should have thrown the 24 - 105 F4 in anyway for the 1/2 day of outside sightseeing that happened. Space however, was that tight, that I just had enough room to squeeze sone very small pressies in for the kids and wife. The backpack finally ended uop at 15 kilos, which is about borderline when you have to walk long distances (eg from exhibition stop train station to exhibition front door is probably 1 kilometer...). The 50mm f1.4 turned out to be an excellent little (and light) number to take along. More pics coming in other (HOST) thread.
