Hi Frits,

 FJW  TTL Offenblendenmessung

So, approximately:

messung == (exposure) metering
blenden == aperture
offen   == open
?

 What is this I see? The old FA100/2.8 macro is now relegated to special 
 order, and replace in the standard line by a boxy looking 100mm f3.5? 
 And it only does 1:2 magnification? This is progress???
