You don't need moulded glass for $1xx type glasses what.. :blah:
The price of the 70-200VR is definitely worth every dollar for what it can produce. If you can't justify the purchase, you definitely of course would find it expensive.
VR doesn't freeze subjects of course, it only stablises your handshake(s). For Fashion Shows where flash is possibly and very likely allowed, VR might not be useful, but the range would.
For stage plays whereby some times flash is prohibited, you'd appreciate the glass for having VR whereby your shutter can go 3 stops lower. That's a lot of help.
