Via equote? If you ask them in person or through phone, the prices might be higher. I got a friend who asked them verbally how much a Nikkor AF 24mm f2.8D is, and they quoted him $580. EQuote price is only $530.
Cathay marina is usually much more expensive than Peninsula plaza. Equote my friend got last yr was 390 + gst. Didnt check much abt Canon prices since I was a Nikon shooter.
