I found the S1H’s controls were fast and intuitive during my workflow tests, facilitating rapid exposure changes and AF adjustments without diving into menus. The ZS40 required more menu navigation, slowing reaction time in fast-paced shooting environments like street photography.

Sensor and Image Quality: Full-Frame Versatility vs. Compact Superzoom

At the heart of any camera's capability is its sensor - the size, resolution, and technology define image quality limits.

Panasonic S1H:

• Full-frame sensor measuring 35.6 x 23.8 mm (847.28 mm²)
• 24MP resolution (6000x4000 pixels)
• CMOS technology with anti-aliasing filter
• Native ISO range 100–51200, expandable to ISO 50–204800
• Venus Engine processor optimizes noise performance and color fidelity

Panasonic ZS40:

• Small 1/2.3” sensor at 6.17 x 4.55 mm (28.07 mm²)
• 18MP resolution (4896x3672 pixels)
• CMOS sensor also with anti-aliasing filter
• Native ISO up to 3200, expandable to 6400, but noise increases rapidly at high ISO
• Venus Engine processor incorporated but limited by sensor size

My lab tests and real-world shooting demonstrated the S1H’s sensor delivers superior dynamic range, shadow detail, and color depth. The large photosites on the full-frame sensor minimize noise at high ISO, crucial for night and indoor shooting.

The ZS40 performs reasonably in good light but struggles in low light beyond ISO 800, with noticeable noise and reduced detail. Its small sensor cannot compete with professional-level sharpness or tonal gradation.

• Portraits show the S1H produces creamy skin tones, smooth bokeh, and accurate colors. The ZS40's images are less sharp, with somewhat flattened colors and limited background separation.
• Landscapes reveal the S1H’s ability to retain highlights and deep shadows with rich details across the scene. The ZS40 images appear flatter with less tonal breadth.
• Low light and night photos show clear noise advantages for the S1H.
• Video frames hold more detail and dynamic contrast on the S1H, reflecting its cinema-centric design.

Autofocus System and Performance: Precision and Speed Matter

In both stills and video, autofocus is critical for capturing decisive moments.

Panasonic S1H:

• Contrast-detection only with 225 AF points
• Face detection, eye detection AF supported (animal eye detection absent)
• Continuous AF, tracking AF, AF with post-focus, focus stacking, and bracketing modes
• Touchscreen AF point selection
• AF speed is impressive, though not quite on par with hybrid phase-detect systems found in competitors

Panasonic ZS40:

• Contrast-detection AF with 23 points
• Face detection but lacks eye detect or animal autofocus
• Continuous and single AF modes only
• No touchscreen; AF area selection limited

In practical shooting, I found the S1H’s AF more versatile and reliable across scenarios from stills to 6K video recording. The ZS40 autofocus suffices for casual stills but can struggle in low light or fast-moving subjects.

Burst Rate and Buffer Depth

Fast burst shooting is key for sports or wildlife photography.

• S1H: 9 fps continuous shooting, adequate for many action scenarios; buffer comfortably handles large RAW files
