Wow! Canon really knows how to impress it’s target market. These Samples looks really good, look at the girls portrait white balance is set to auto and yet it produces beautiful colours. They also used a fast prime lens EF50mm f/1.2 USM set at f/2.8.
The photographers who took these photo are pro’s and knows how to set good lighting and camera setting, don’t expect that the D7 can do these wonderful shot on it’s own.
