Thanks for your time Josef. I visited 'virtual gallerie' and like your work,
particularly 'arte povera' and 'random'.
Now to the lens. I hunted around Bjorn Rorslett's lens survey and found
what I believe to be the same lens. He says
"A true treat for any lover of plastic-fantastic items, this humble lens accompanies the low-end SLRS such as F/N60/65. I've taken apart this lens to extract its matrix chip print, and shudder by the very thought of its poor internal construction quality (in fact, the lens barrel is just kept together with sticky tape!!).
As an optical device, you actually get more than you have bargained for. The performance is not that bad and at f/8, quite decent images result. However, don't drop the lens because it certainly won't survive the impact."
So that is 2 votes for plastic. However, I think I'll use this lens for
'walk-abouts' which often get me into places where I don't really
want to jepordize the good glass. See if I can't squeeze some good
out it.
