Lucky you, or you'd be wrong in an enthusiast dslr forum discussing the newest toys. Quoting a famous German phrase from the early 20th century Weihmar Republic: "Wer hat uns verraten? Sozialdemokraten"!
Sorry to get off-topic but this quote was coined by the nationalistic / conservatives that happily joined the big war and then, when the social democratic government had to exit it were looking for a scapegoat. If you disagree with Tinky at least don't bring that right wing nationalistic slogan.
Throwing Social-Democrats and communists into one pot shows a lack of understanding how the social democratic party (especially in Germany) developed.
