The P150 employs a high-quality F2.8-5.2 Carl Zeiss Vario-Sonnar 7.9-23.7mm optical zoom lens with 38 to 114mm coverage (as compared to a 35mm camera.) This is an all-glass lens consisting of 7 elements in 5 groups with 3 aspheric elements. The lens retracts into the body when powered down and is protected by a built in lens barrier.

Optional wide angle VCL-DH0730, telephoto VCL-DH1730 and super telephoto VCL-DH2630 lenses as well as 37mm filters can be attached using the VAD-PHB conversion lens adapter.

The P150 employs a 5-point Multi-point auto focus system, with automatic or user selectable AF point. The center AF target area can be wide or narrow. The working range is from 19.7 inches to infinity in normal mode and in Macro the coverage is from 2.4 inches to infinity. You can also manually select one of five focus distance presets from 0.1m to infinity.

The P150 features an AF Assist beam designed to achieve accurate focus on subjects with little contrast in dark conditions. It also brightens the LCD screen momentarily to aid in framing.

The eyelevel optical real-image zoom viewfinder has a field of view of approx. 80-85% (80% in wide and about 85% at tele) of the captured image. There is no diopter adjustment. The LEDs indicate card activity/Self-Timer, Autofocus/Auto Exposure Lock and Flash status.

The built-in flash has modes for Auto, Forced On, Forced Off, and Slow Synchro. Red-eye reduction can be enabled or disabled via the Setup menu. It uses a pre-flash for precise metering of the exposure. It also has auto daylight synchro fill flash for backlit or shadowed subjects as well as dynamic flash white balance for greater color accuracy. The working range for the flash is approx. 8 in. - 11 ft. (0.2 - 3.5 m) Wide and 1.0 - 8.3 ft. (0.3 - 2.5 m) Telephoto, when using ISO Auto.
