• Resolution: 14 megapixels (4320x3240) with a 4:3 aspect ratio.
• Image Quality: Limited dynamic range and high noise levels at ISO above 400, which restricts low-light usability.
• Color Depth & Detail: The CCD sensor provides decent color reproduction but softens fine details due to small pixels.

Sony A7 II

• Sensor: Large 35.8x23.9 mm full-frame CMOS sensor.
• Resolution: 24 megapixels (6000x4000) with a 3:2 aspect ratio.
• Dynamic Range: Exceptional, as supported by DXO Mark scores (Dynamic Range 13.6 EV, Color Depth 24.9 bits).
• Low-Light Performance: ISO sensitivity up to 51200 with excellent noise control.
• Raw Support: Full RAW file support giving maximum editing flexibility.

My Experience: Capturing landscapes with the A7 II revealed stunning shadow and highlight preservation unseen in the ST80. Skin tones in portraiture appeared lifelike and natural with minimal artifacts, while the ST80’s sensor struggled to maintain detail without noise. For pixel-peepers and professionals, full-frame is a game-changer.

Control Layout and User Interface

Effective user interface design can boost creative throughput immensely.

Samsung ST80

• Controls: Relies heavily on touchscreen input, which is responsive but limiting for manual adjustments.

In practice, I appreciated the A7 II’s tactile feedback and capacity to change settings without diving into menus. The absence of touch control is mitigated by extensive physical buttons, preferred by professionals for speed and precision.

Autofocus Performance

Autofocus affects every shooting genre, especially fast-action photography like wildlife and sports.

While the ST80’s autofocus suffices for casual snapshots, I found it struggles with moving subjects or low contrast. The A7 II offers a sophisticated AF system that locks focus reliably on wildlife, sports, and portrait subjects using eye detection. It smooths tracking through bursts up to 5 fps, adding confidence in dynamic shoots.

Video Capabilities

Video shooting is critical for many users today - let’s see how each holds up.

Samsung ST80

• Video Resolution: 720p HD (1280x720) at 30fps max, recorded in Motion JPEG format.
• Mic & Audio: No external microphone port; built-in mic only.
• Stabilization: Optical image stabilization helps reduce shake in handheld clips.
• Limitations: No 4K, limited manual control, and compressed codec reduce final quality.

Sony A7 II

• Video Resolution: Full 1080p HD at 60fps with AVCHD and XAVC S codecs.
• Audio: Dedicated mic and headphone jacks allow professional-grade audio monitoring.
• Stabilization: In-body 5-axis sensor-shift stabilizer delivers smooth footage without lenses supporting OIS.
• Additional Features: Supports time-lapse recording via downloadable apps.

From hands-on tests, the A7 II delivers richly detailed footage with smooth autofocus transitions in video mode - far superior to the ST80, which feels severely limited for today’s content creators.
