Exploring Controls and User Interface

Simplicity or Customizability?

The Casio EX-Z270 sticks to a very basic control scheme: no manual exposure modes, no aperture or shutter priority, and no manual focus options. Its fixed 2.7-inch LCD is small with only 115k-dot resolution, offering live view but limited feedback. The camera includes sensor-shift image stabilization and a built-in flash, but autofocus relies on simple contrast detection without face or eye detection.

In comparison, the Samsung NX300 boasts an extensive control set with shutter and aperture priority, full manual exposure, exposure compensation, and more. The 3.3-inch tilting AMOLED touchscreen with 768k-dot resolution provides precise focus control - touch AF - and effortless menu navigation. Its autofocus system is phase-detection-based with contrast detection assist, featuring 247 focus points and good face detection for portraits.

During my hands-on evaluation, the NX300’s touchscreen and customizable buttons make it easy to adapt the camera to your shooting style, whereas the EX-Z270 steers more toward “point and shoot” simplicity. If you want full control and live adjustments, the NX300 is clearly more capable.

Sensor Technology and Image Quality: The Heart of the Matter

From a Tiny CCD to a Large APS-C CMOS Sensor

This is perhaps the most important distinction between these cameras.

• The EX-Z270 uses a 1/2.5-inch CCD sensor (5.74 x 4.31 mm; 24.7 mm² area) with 10 megapixels and a maximum sensitivity of ISO 1600. CCD sensors from this era generally deliver decent color but struggle with noise and dynamic range at higher ISOs.

• The NX300 comes with a much larger APS-C CMOS sensor (23.5 x 15.7 mm; 369 mm² area) sporting 20 megapixels and ISO up to 25600. Combined with the DRIMe IV processor, this sensor delivers excellent image quality, wide dynamic range, and low noise, especially important for demanding disciplines like landscapes, portraits, and night photography.

My testing results:

• The NX300 produces noticeably sharper, more detailed images with better color depth and shadow recovery. The larger sensor size allows superior background blur (bokeh), crucial for portraits.

• The EX-Z270’s images are respectable at base ISO but quickly show noise and lack of detail when pushed, reflecting its compact sensor limits.

For photographers prioritizing image quality, post-processing flexibility, and low-light capability, the NX300’s sensor is miles ahead.

Autofocus System: Fast and Smart vs Basic Contrast Detection

The EX-Z270 employs contrast-detection autofocus with no face or eye detection and only a single focus point option. This setup is adequate for well-lit, static subjects but struggles with moving targets and low light.

The NX300 utilizes a hybrid autofocus system combining phase detection and contrast detection across 247 AF points, including face detection. It supports continuous AF and tracking, which benefits wildlife, sports, and portrait photographers.

In real-world use, I found the NX300 significantly faster to lock focus and more reliable tracking of subjects in motion or changing poses. The EX-Z270 often required multiple attempts to focus accurately - an expected limitation for simple ultracompacts.
