I posted some information on the Fotga tubes a few months ago:

Six months later, I no longer use them, their aluminium mating surfaces have grown increasingly unhappy with the stainless steel surfaces of my lenses... One time (the last time!) I wasn't sure I was going to be able to take the tube off the lens without damage, about 3 minutes of slowly increasing panic! The tiniest drop of penetrating oil left for 20 seconds did the job.

Thanks, that is useful information - is it really aluminium? Does it just have poor anodising?
