[Brightcolours]

That makes me wonder - Klaus, did you ever think of adding block diagrams to your reviews (probably on the first page of each) if they can be easily sourced? While a block diagram won't say much to most of us (certainly doesn't tell me much WRT expected lens performance), it could be a nice touch.

Lens construction diagrams will pose a copyright issue in german law (some silly judge made a ruling that linking to images is copyright violation for german websites). So the only way would be to draw them oneself...
