Large APS-C (23.6 x 15.7 mm) sensor Large sensors provide shallower depth of field and a nice blurry background for your portrait shots.
Average Resolution Sensor: 16.0MP Leica TL's 16.0MP resolution is not the best in its class but you can still manage relatively large prints of your portrait shots and crop without losing too much detail.
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.
No Image Stabilization Due to the lack of sensor based Image stabilization, Leica TL users have to rely on lenses with optical IS in order to maximize the sharpness of their handheld portrait shots. Currently there are native Leica TL mount lenses with Image Stabilization for Leica TL.
