Average sized 1″ (13.2 x 8.8 mm) sensor Even though Nikon 1 V1's sensor is significantly larger than a typical compact camera sensor, it is still hard to achieve that shallow depth of field and a blurry background for your portrait shots.
Electronic Built-in Viewfinder During a portrait shoot, using a viewfinder allows the photographer to stabilize the camera and reduce the camera shake since it is closer to the body. Besides, it comes handy where LCD screens are very hard to read under bright sunlight.
Average Ergonomics&Handling Good handling and existence of well placed physical controls on the camera body is very important during portrait shooting. It is faster and more intuitive to change the camera settings with dedicated buttons and knobs instead delving into the menus on the LCD.
Very Low Resolution Sensor: 10.0MP Nikon 1 V1's 10.0MP sensor will not provide much room for cropping or large printing your portrait shots.
No Image Stabilization Due to the lack of sensor based Image stabilization, Nikon 1 V1 users have to rely on lenses with optical IS in order to maximize the sharpness of their handheld portrait shots. Currently there are native Nikon 1 mount lenses with Image Stabilization for Nikon 1 V1.
