Both cameras have distinct design philosophies and target users, which makes this comparison unique and rewarding for understanding practical differences.

Drawing on over 15 years of camera testing and hands-on use, I’ll dissect how each performs across various photography genres, their technical nuances, and real-world usability. By the end of this in-depth article, you’ll have a clear grasp of which camera aligns better with your needs.

First Impressions: Form Factor and Ergonomics

Photography often begins with the feel of the camera in your hands. The Sony NEX-3 sports a rangefinder-style mirrorless body with finite control options, while the WX150 is a classic pocketable compact.

• NEX-3: Measuring 117x62x33mm and weighing 297g without lens, it’s compact but offers solid handling for its class. The larger grip area allows more secure handling, especially with varied lens options.
• WX150: At just 95x56x22mm and 133g, this camera’s ultra-compact size weighs heavily toward portability but sacrifices grip comfort and manual controls.

Hands-on takeaway: In my experience, the NEX-3 offers more confident handling during longer shoots, while the WX150 excels for spontaneous travel and street photography where size constraints matter.

Design and Control Layout: What’s at Your Fingertips?

When testing usability, button placement and interface design are vital. Cameras must be intuitive and quick to operate.

• NEX-3: Features dedicated exposure modes (manual, aperture, shutter priority), an exposure compensation dial, and a responsive shutter release that enable creative control. It lacks an electronic viewfinder which means reliance on the LCD for composing shots.
• WX150: Simplicity rules here, with fixed aperture and shutter controls, geared more toward casual shooters. No manual exposure modes or dedicated dials.

The NEX-3’s layout promotes deliberate shooting and experimentation, whereas the WX150 simplifies operation, which can be appealing for quick snaps but frustrating if you want creative levers.

Sensor Technology: The Heart of Image Quality

Sensor size and technology fundamentally affect image quality, especially under challenging conditions.

• NEX-3: Equipped with a 14MP APS-C CMOS sensor (23.4 x 15.6 mm), this sensor is roughly 13x larger in area than the WX150, making a huge difference in light-gathering ability and depth of field control.
• WX150: Utilizes an 18MP 1/2.3" BSI-CMOS sensor (6.17 x 4.55mm), smaller and packed with higher pixel density, which tends to increase noise at higher ISOs.

Technical insight: From my testing protocols, APS-C sensors reliably produce superior dynamic range and color depth. The NEX-3 scores a DxO overall rating of 68, with excellent 12 EV dynamic range and 22.1-bit color depth, attributes that deliver nuanced image tones and overall quality. The WX150 has not been formally tested by DxO, but the small sensor size inherently limits its noise performance and dynamic range.

LCD Screen and User Interface: Composing and Reviewing Shots

Reviewing your images and framing your shots is critical; screen quality impacts this immensely.

• NEX-3: A 3-inch tilting TFT Xtra Fine LCD with 920k dots provides flexible viewing angles and sharp detail - ideal for high or low angle shots. This contributes to precise focus checking and composition.
• WX150: Has a fixed 3-inch ClearPhoto TFT LCD with 461k dots, noticeably lower resolution and fixed angle, limiting compositional versatility.

Over many real-world shoots, I found the NEX-3’s adjustable, sharper display a distinct advantage when working outdoors or in tricky lighting, where reflections and glare dull screen visibility.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraits demand accurate skin tone capture, natural bokeh (background blur), and reliable autofocus, especially for eyes.

• NEX-3 Pros:

  • Larger sensor produces smoother tonal gradations and creamy background separation due to shallower depth of field.
  • Face detection autofocus works well for static subjects in good lighting.
  • Manual exposure modes let you fine-tune settings for skin tone rendition.

• NEX-3 Cons:

  • No eye-detection AF or animal eye AF, so focus may occasionally fall a bit shy of critical sharpness on eyes.

• WX150 Pros:

  • Built-in face detection autofocus suitable for casual portraits.
  • Effective autofocus in good light and decent skin tone rendition given sensor limits.

• WX150 Cons:

  • Small sensor limits bokeh quality with more noticeable depth of field (less subject isolation).
  • Maximum aperture slows down to f/5.9 at telephoto end, reducing low-light portrait flexibility.

If your main focus is dedicated portraiture with creative control and shallow depth of field, the NEX-3 is your clear winner.

Landscape Photography: Dynamic Range and Robustness

Landscape photography benefits from high resolution, wide dynamic range to handle shadows and highlights, and ideally ruggedness for outdoor use.

• NEX-3:

  • APS-C sensor with excellent dynamic range (~12 EV) to capture bright skies and deep shadows.
