• The VG-145’s CCD sensor with limited ISO sensitivity results in more noise at higher ISOs and less tonal gradation.
• Raw image capture on the RX100 III offers greater post-processing flexibility; Olympus’s JPEG-only approach restricts editing latitude.
• The RX100 III’s anti-aliasing filter combined with higher resolution helps deliver crisp detail without moiré issues.
• In daylight conditions, both cameras produce decent images, but the RX100 III’s superior color depth and shadow recovery stand out in my tests.

Recommendation: Serious shooters focused on image quality and editing potential should favor the Sony RX100 III. For casual snapshots under good lighting, the VG-145 suffices.

Screen and Viewfinder Comparison

The rear screen and viewfinder usability greatly affect shooting comfort and framing options.

• The Olympus has a fixed 3-inch TFT LCD with only 230k pixels - noticeably dimmer and less crisp, especially in bright outdoor conditions.
• The Sony RX100 III offers a sharp 3-inch 1.2 million pixel tilting screen, perfect for low or high-angle compositions.
• RX100 III includes a pop-up electronic viewfinder with 1440k pixel resolution, 100% frame coverage, and 0.59x magnification which is a significant boon for bright light shooting and detailed focusing.
• VG-145 lacks any viewfinder, forcing reliance on the LCD, which can be problematic in direct sunlight.

Practical Takeaway: The RX100 III’s screen and EVF combination offer greater flexibility and reliability, especially for enthusiasts working in varied lighting conditions.

Photography Disciplines Explored: Which Camera Suits Your Style?

Now, let's see how these cameras fare in specific photography genres based on my extensive testing.

Portrait Photography

• VG-145: Modest aperture range (F2.8-6.5) and 5x zoom from 26mm equivalent (wide) to 130mm (telephoto). While it does face detection, the limited sensor size restricts depth-of-field control, leading to somewhat flat images with limited bokeh separation of the subject.
• RX100 III: Faster maximum aperture (F1.8-2.8) and 3x zoom from 24-70mm equivalent. The 1” sensor creates better subject isolation with nicely rendered backgrounds. Eye detection AF helps nail sharp focus on the eyes, enhancing portrait quality.

Recommendation: For flattering skin tones and creamy background blur, the RX100 III excels. The VG-145 is fine for family snapshots but lacks finesse in portraiture.

Landscape Photography

• VG-145: 14MP resolution is sufficient for typical landscape prints but the limited dynamic range of the sensor hampers shadow detail recovery.
• RX100 III: 20MP sensor with excellent dynamic range (over 12 stops tested) captures rich tonal gradations and textures. The kit lens covers a 24mm wide angle suitable for landscapes, and better weatherproofing would be preferable but is absent in both models.

Recommendation: Enthusiasts who value image pride should choose the RX100 III for detailed landscapes, while the VG-145 suits beginners capturing everyday scenery.
