Originally posted by audiodoc I am taking small planes between locations and that is their weight limit. I managed on my last trip with 1 carry on and a backpack
I am a bad boy. I have taken 20kgs of kit as hand luggage onto a smaller aircraft. Not much choice as it was needed for a job. I had better not tell you what other things I have done to hide my weight other than pockets come in very handy until after all the checking has been done. I would stick with their limit and not take the risk. I can't speak for the K30, but the K5 will improve almost any lens you own.
I find when I tell people I am a photographer they go out of their way to accommodate me particularly in Africa.
