Hi tan I fly a lot and use a pelican 1600 for air travel: holds 2X LX 1X MX 8 pentax lenses 2 converters 1 voigtlander body 2 lenses 1 xpan body 2 lenses 1 vivitar 283 1 vivitar 2500
no way to carry this lot on board with room for film too! I use a hefty combination pelilock and the case is bright [well dirty] yellow. I also have a pelican 1500 that holds 5 more vivitar 283s, quantum battery packs,polaroid back for LX, slaves, flashmeter and all my other lighting goodies. I have seen these literally being thrown on the plane [like a masochist I always sit over the luggagehatch to watch them being loaded]..........................................so far so good.............the 1600 cost USD 30 on ebay! I carry on a billingham hadley with 2x voigtlander bodies and more lenses + FILM and if poss a Billingham 225 [normally has the pentax gear in] full of FILM If this isn't feasible then you can get an awful lot in a domke vest! [doesn't count as carry on!] just be sure to check in early enough for them to security check all this.............. Just my .2 euro worth Clive Antibes France
