Since I realized that selling my MF gear would probably mean to give it away for (IMO) too low prices I ended up in keeping it (at least so far).
Since right now I dont feel the patience and creativity to shoot "real" MF subjects I decided to also use MF more often again for snapshots.
Here is one with the 80 Xenotar at f2.8, ISO 800.
And yes- I guess the milk tasted good.
I still really do like the drawing of the Hy6-lenses and also of the Sinar back. ISO 800 is fully usable IMO (not only when reduced for web)
