If manual or semi-automatic exposure control is important, the WG-4 GPS’s shutter priority mode (albeit limited compared to professional cameras) provides flexibility absent in the ST150F. The absence of touch functionality on both cams won’t bother enthusiasts familiar with physical controls.

Sensor Technology & Image Quality: The Heart of the Camera

Both cameras feature a 1/2.3" sensor size (6.17 x 4.55 mm), standard for compact cameras, with a 16MP resolution (4608 x 3456 pixels). However, their sensor types differ notably: Ricoh employs a BSI-CMOS sensor, whereas Samsung uses a CCD sensor.

BSI (Back-Side Illuminated) CMOS sensors, like in the WG-4 GPS, enhance low-light sensitivity and dynamic range by capturing more light per pixel - an advantage translating to cleaner images with less noise, especially beyond ISO 800. The CCD sensor in the ST150F, while traditionally delivering sharp color rendition and good image quality at base ISO, struggles with noise at higher sensitivities and typically lacks the speed and power-efficiency benefits of CMOS designs.

Practically, this means the WG-4 GPS produces crisper images with richer tonal gradation in portrait, landscape, and night photography, while the ST150F’s outputs may exhibit softness and increased noise in challenging lighting.

On maximum ISO, WG-4 extends up to 6400, whereas ST150F caps at ISO 3200, underlying the Ricoh’s better low-light capabilities, albeit with caveats regarding noise in very high sensitivities for both.

Viewing and Interface: Composing and Reviewing Shots

The Ricoh WG-4 GPS sports a 25-100 mm equivalent focal length (4x zoom) with a bright f/2.0–4.9 aperture range, lending versatility from wide-angle landscapes to moderate telephoto. The fast f/2.0 wide end enables better low-light shooting and shallow depth of field for portraits with distinguishable background separation.

Samsung ST150F’s zoom extends slightly longer at 25-125 mm (5x zoom) but with a dimmer maximum aperture of f/2.5–6.3, limiting its efficacy in low light and portrait bokeh quality. The narrower apertures introduce the need for higher ISO or slower shutter speeds, increasing noise or motion blur risk.

Importantly, Ricoh’s macro focus distance allows shooting from as close as 1cm, ideal for detailed nature or macro photography, whereas Samsung lacks specified macro capabilities, reducing close-up sharpness and focus precision.

Overall, Ricoh offers superior optical performance for users requiring flexibility across genres, from wide scenes to detailed close-ups.

Autofocus System: Speed and Precision

Ricoh’s WG-4 GPS features contrast-detection autofocus with 9 focus points and face detection, supporting single, continuous, and tracking AF modes. Although contrast detection is generally slower than phase detection, WG-4 GPS’s implementation is relatively responsive for a rugged compact. Face detection improves portrait accuracy but lacks advanced animal eye AF.

Samsung ST150F offers contrast detection with unknown or fewer AF points, lacks continuous AF, and only provides single AF and face detection, limiting its efficacy for fast-moving subjects seen in wildlife or sports.

In practice, WG-4 GPS’s AF system outperforms ST150F in tracking moving subjects and maintaining focus in complex scenes, though both fall short compared to mirrorless or DSLR cameras.

Continuous Shooting and Video: Capturing Motion

Ricoh WG-4 GPS can shoot at 2 frames per second (fps) continuously - a modest rate suitable for casual sports or wildlife snapshots but insufficient for dedicated action photography. The camera supports 1080p Full HD video at 30p and 720p at 60p, employing H.264 compression. While lacking microphone inputs, the sensor-shift image stabilization enhances video smoothness, an asset missing on the Samsung.

Samsung ST150F omits specified continuous shooting, likely limited due to hardware and design focus. Video maximum resolution tops out at 720p at 30fps, encoded in MPEG-4 or H.264. Its absence of image stabilization negatively impacts handheld video smoothness.

For users embracing video content creation, Ricoh WG-4 GPS’s higher resolution and stabilization offer clear advantages, albeit at foundational levels that may disappoint more advanced videographers.
