Sony H400 vs Sony RX100 IV: An Expert Comparison for Enthusiasts and Pros
In the vast landscape of Sony’s Cyber-shot line, two cameras stand out for dramatically different reasons: the Sony Cyber-shot DSC-H400, a budget-friendly superzoom bridge camera, and the Sony Cyber-shot DSC-RX100 IV, a premium large sensor compact champion. Both appeal to photographers seeking high image quality and convenience but serve very distinct photographic ambitions and styles. Today, after hours spent with both models in the studio and out in the field, I aim to unpack their real-world capabilities across genres, scrutinize their technical nuances, and help you decide which is truly worth your investment in 2024.
Let’s get started with an honest, detailed, and comprehensive comparison that goes well beyond specs and marketing hype.
First Impressions and Ergonomics: The Feel of the Camera in Your Hands
Often overlooked but crucial to long shooting sessions, ergonomics can make or break your experience. The H400 - built in 2014 as a bridge camera - feels substantial with its SLR-like body and a hefty 628g weight. In contrast, the RX100 IV is feather-light and pocketable at just 298g, reflecting its premium compact DNA.
Handling each, the Sony H400 feels bulky but reassuring - a camera you hold like a DSLR, with a decent grip that grows on you after a few hours of use. However, its build quality is mostly plastic, and while it doesn’t boast weather sealing, it does feel solid for casual shooting in benign conditions.
The Sony RX100 IV impresses with its machined metal exterior and compact form factor that slips seamlessly into jacket or even large pants pockets. It exudes refinement, and though smaller, boasts a more confident grip than you might expect given its size. Being ultra-portable makes it perfect for travel and street shooters who prioritize discretion and ease of carry without sacrificing image quality.
Control Layout and User Interface: Speed and Intuitiveness
In-camera controls and usability directly influence how quickly and efficiently you can shoot - vital for dynamic situations like sports or street photography.
The H400’s control scheme is basic yet straightforward. It lacks customizable buttons or a touchscreen, limiting fluid operation. Menus are user-friendly but somewhat dated. The electronic viewfinder (EVF) has a low resolution (201k dots), making manual focusing and critical evaluation challenging. Its Clear Photo LCD screen - fixed at 3 inches with only 460k dots - doesn’t inspire confidence for playback or outdoor viewing.
On the other hand, the RX100 IV features a more sophisticated interface with exposure dials and buttons placed with intent, allowing rapid adjustments on the fly. The EVF is a highlight here: a bright OLED panel with 2,359k dots and 0.59x magnification, a real boon when shooting bright landscapes or low-light events. The 3-inch tilting LCD with 1,229k dots provides sharp framing and playback, though sadly no touchscreen.
While neither camera incorporates an illuminated button system common in some enthusiast models, the RX100 IV’s superior control layout feels designed for serious photographers who want direct access to manual modes and fast AF area selection.
Sensor and Image Quality: The Heart of the Camera
No camera comparison is complete without an in-depth look at the sensor and image quality, the foundation of any photographic system.
Sony H400 is outfitted with a small 1/2.3” CCD sensor measuring roughly 6.17 x 4.55 mm and a 20MP nominal resolution. While this sensor size enables the tremendous 63.3x optical zoom range, it imposes significant limitations on image quality. Small sensor size inherently restricts dynamic range, low-light performance, and depth of field control. There's a modest anti-aliasing filter, and the native ISO tops at 3200.
In practical use, images show acceptable sharpness but struggle with noise beyond ISO 400. The CCD sensor’s limited dynamic range means highlight retention and shadow detail suffer, especially in tricky lighting. Skin tones, while pleasant in controlled light, lack the subtle nuances rendered by larger sensors.
Enter the Sony RX100 IV, with its 1” 20MP BSI-CMOS sensor sized at 13.2 x 8.8 mm, nearly four times the surface area of the H400’s chip. Its backside illumination design enhances light gathering, yielding superior signal-to-noise ratio and dynamic range. DxO Mark’s tests confirm with a very respectable 12.6 stops of dynamic range and a color depth of 22.9 bits (compared to no DxO rating for H400).
The RX100 IV’s sensor excels at high ISO, with usable images at ISO 3200 and beyond - a key advantage for night, indoor, and sports photography. Its better tonal gradation faithfully captures skin textures and subtle color shifts that make portraits pop.
Both cameras provide maximum resolution around 20MP, but the RX100 IV outputs nearly twice the pixel dimensions per side, preserving more detail and enabling larger prints or cropping flexibility.
Zoom and Lens Performance: Reach Versus Optical Quality
The H400's defining feature is its astonishing 25-1550mm (35mm equivalent) 63.3x zoom lens, unmatched in this price class. It’s perfect for wild animal shoots where reaching distant subjects is critical without lugging a heavy telephoto lens.
However, the lens's maximum aperture of f/3.4-6.5 combined with the small sensor incurs harsh compromises on image quality at long end - sharpness decreases, chromatic aberrations creep in, and dof control becomes virtually impossible.
In contrast, the RX100 IV’s 24-70mm f/1.8-2.8 Zeiss Vario-Sonnar lens covers a moderate 2.9x zoom range but boasts fast apertures that enable beautiful background separation and impressive low-light gathering. Its optical construction heavily prioritizes sharpness, contrast, and minimal distortion. While it can’t match the H400’s reach, its quality and aperture outperform most similar compacts.
For macro enthusiasts, the RX100 IV’s minimum focus distance is about 5cm, enabling greater creative freedom than the H400, which doesn’t specialize in macro at all.
Autofocus Systems and Speed: Catch the Moment or Miss It?
Autofocus can make or break sports, wildlife, and street photography. Here, the differences between these two Sonys underscore their different intended use cases.
The H400 uses contrast-detection AF with unspecified focus points, featuring face detection but no continuous AF tracking - and a sluggish autofocus lag. Given its single frame per second burst rate and no live view AF, the H400 is not optimized for fast action. You’ll find it better suited to landscapes, casual portraiture, or static subjects.
Conversely, the RX100 IV offers 25 AF points, continuous AF tracking, face detection, and phase-detection pixels embedded in the 1” sensor, resulting in snappier, more accurate autofocus performance, even in lower light or when subjects move erratically.
Face detection works flawlessly on the RX100 IV, locking quickly on eyes, and refocusing intelligently during bursts up to 16 fps - the kind of responsiveness required for sports and wildlife. The silent electronic shutter adds discretion if needed.
Burst Rate and Buffer: Action Photography Friend or Foe?
Analyzing continuous shooting performance clarifies who’s ready for action photography.
-
Sony H400: Offers a pedestrian 1 fps continuous shooting rate, inadequate for action scenes or wildlife that require capturing fleeting moments. Buffer size and lag cause further delays, discouraging burst mode usage.
-
Sony RX100 IV: Impressively high burst rate at 16 fps with continuous autofocus and exposure tracking. The buffer can hold 62 RAW or over 200 JPEG images before slowing. This makes the RX100 IV a small but fierce contender for sports shooters who prioritize portability.
Video Performance: Beyond Stills
Video is a major consideration in modern cameras, especially for hybrid shooters.
The H400 shoots only 720p HD video at standard frame rates and supports basic MPEG-4/H.264 formats. While it has a microphone port (a rare feature in this class), the rest of the video system is rudimentary, lacking 1080p or 4K capability, stabilization modes suited to video, or advanced audio inputs.
The RX100 IV, debuting a year later with a more powerful Bionz X processor, delivers full 4K UHD (3840 x 2160) video at 30/25/24 fps, alongside full HD 1080p up to 60p and slo-mo up to 120 fps. Its XAVC S codec ensures cleaner videos with less compression. Optical image stabilization complements handheld shooting, though lacks in-body stabilization.
Despite no external microphone input, the onboard mic captures audio cleanly. The RX100 IV is clearly geared toward advanced video users and multimedia content creators demanding sharp 4K footage without a big rig.
Display and Viewfinder Quality: Composing the Shot
The interface for composing and reviewing images is critical.
The H400’s 3-inch fixed Clear Photo LCD at 460k dots pales against the RX100 IV’s 3-inch tilting LCD screen with 1,229k dots. The higher resolution and tilt action screen on the RX100 IV enable more flexible shooting angles and better visibility in bright sunlight.
The electronic viewfinders further underscore this gulf: the H400’s low-res EVF (201k dots) is grainy and lacks detail, complicating manual focusing and framing. RX100 IV’s OLED EVF triples the resolution with 2,359k dots, offering sharp previews and excellent color fidelity.
If you rely heavily on the viewfinder or intend to shoot in bright conditions, the RX100 IV is the clear winner here.
Battery Life and Storage: Practical Considerations
Though seemingly mundane, battery endurance and memory options shape shoot day outcomes.
Both cameras accept SD/SDHC/SDXC cards, with the H400 also supporting Sony’s Memory Stick Duo formats, though standard SD cards are recommended.
Battery life is comparable: the H400 manages around 300 shots per charge, while the RX100 IV offers approximately 280 shots. This slight difference is negligible, but the RX100 IV’s smaller battery makes carrying spares advisable for extended shoots.
Connectivity and Extras: Modern Features
The H400 is limited to USB 2.0 and HDMI outputs, with no wireless connectivity, NFC, or Bluetooth - reflecting its older design refreshingly straightforward, but lacking modern conveniences like Wi-Fi transfer or remote shooting.
The RX100 IV includes built-in Wi-Fi and NFC, enabling seamless wireless file transfers and tethered shooting via smartphone apps, a serious advantage for professional workflows and social media content generation.
Image Samples from Both Cameras
Let’s look at actual images to gauge real-world output quality differences.
The H400 excels in telephoto reach, capturing distant subjects at extents impossible for the RX100 IV. However, image softness, noise, and artifacting become evident at extremes. Colors tend to be slightly muted in difficult light.
By contrast, RX100 IV images show superior detail, dynamic range, and color accuracy. Portraits feature smooth skin tones and natural bokeh. Landscapes reveal rich shadow detail and punchy colors, with excellent sharpness even at wider apertures.
