Sony HX400V vs Sony RX1: A Hands-On Comparison of Two Distinct Sony Cameras

Sony’s Cyber-shot lineup offers a wide array of cameras catering to various photography needs - from casual shooters to seasoned professionals. Among these, the Sony HX400V and the Sony RX1 represent two very different approaches within the compact camera category. One leans heavily on extensive zoom capabilities at an accessible price, while the other focuses on uncompromising image quality with a full-frame sensor nestled in a compact body.

Having tested thousands of cameras over 15 years, I’ve spent significant time with both models. This comparison aims to give you the unvarnished truth about their performance across disciplines, build quality, usability, and value, so you can confidently decide which fits your shooting style and budget.

Design and Handling: Bridge vs Large Sensor Compact

At first glance, these two cameras couldn’t be more different in form factor. The Sony HX400V is a bridge camera - SLR-like in appearance - offering a comfortable grip, a pronounced electronic viewfinder, and physical control dials typical of enthusiast superzooms. The RX1 is a compact camera with a simple design and minimalist controls, prioritizing portability without sacrificing image quality.

• Sony HX400V: Measures 130x93x103 mm and weighs around 660 grams, relatively bulky for a compact but manageable for a superzoom with its deep grip and extensive telephoto reach.

• Sony RX1: Smaller at 113x65x70 mm and lighter at 482 grams, it slips easily into larger jacket pockets or a compact bag, making it ideal for discreet shooting.

The HX400V offers an articulating tilting LCD screen with 921k-dot resolution, useful for shooting at unconventional angles. The RX1 sticks to a fixed, 1229k-dot “Xtra Fine” TFT LCD screen, which boasts excellent clarity and contrast but lacks versatility in positioning.

Control layout favors the HX400V for tactile dials and customizable buttons, giving quick exposure and zoom adjustments. The RX1’s minimalist control scheme emphasizes simplicity, focusing on aperture and shutter speed dials that harken back to classic rangefinder aesthetics.

In my hands-on experience, users who prefer direct access to settings will find the HX400V more accommodating, while those favoring a stripped-down approach that fosters compositional creativity may gravitate toward the RX1.

Sensor Technology and Image Quality: Small Sensor Superzoom vs Full-Frame Compact

This is where the cameras’ philosophies diverge markedly. The HX400V uses a 1/2.3-inch BSI CMOS sensor measuring 6.17 x 4.55 mm, delivering 20 megapixels but constrained by sensor size. The RX1 boasts a 35.8 x 23.8 mm full-frame CMOS sensor capturing 24 megapixels.

Key Differences:

Sensor area differences are stark: The RX1’s sensor is nearly 30 times larger, translating directly into better image quality, noise performance, and dynamic range.

Real-world impact:

• The RX1 creates images with beautifully shallow depth of field, smoother gradations, and better color fidelity. Its full-frame sensor excels for portraits and landscapes requiring detail retention and tonality.

• The HX400V, while offering tremendous versatility through its 50x zoom, produces images with more noise and less dynamic range, especially in low light. It cannot shoot RAW, limiting post-processing flexibility.

You can clearly see this quality difference reflected in sample images:

The RX1 is clearly superior for large prints and professional output, but the HX400V’s sensor is typical for superzoom shooters who prioritize convenience and reach over ultimate image quality.

Autofocus and Speed: Tracking Subjects Across Genres

Both cameras employ contrast-detection autofocus with face detection, but their AF systems differ significantly in sophistication.

• Sony HX400V: Features 9 focus points and includes continuous AF and basic tracking. It’s tuned for stills where focus confirmation is prioritized over speed. Zooming from wide to 1200mm equivalent means focus can hunt slightly but remains generally reliable for casual wildlife or sports.

• Sony RX1: Offers 25 AF points and face detection but lacks continuous AF tracking found in modern mirrorless cameras. AF speeds are reasonable but not designed for fast action. Its strength lies in precise manual focus aided by focus peaking, favored by portrait and landscape shooters.

Burst shooting capabilities also highlight differences:

For fast-moving subjects like wildlife and sports, the HX400V’s higher burst rate and zoom flexibility make it the better choice, though it does not excel compared to dedicated sports cameras.

In street or travel scenarios, the RX1’s silent shutter and manual focus precision enhance discretion and compositional control, albeit with slower shooting speed.

Build Quality and Weather Resistance

Neither model boasts comprehensive weather sealing. The HX400V and RX1 both lack dustproofing or waterproofing, although the HX400V’s bridge-style body feels rugged enough for moderate outdoor use.

The RX1’s all-metal body conveys solidity and is crafted for longevity, but handling with gloves or in inclement conditions requires care due to its smaller controls.

Lenses and Optical Performance

Both cameras feature fixed lenses, but with vastly different applications.

• Sony HX400V: Equipped with a 24-1200 mm equivalent f/2.8-6.3 zoom lens delivering immense versatility. Optical image stabilization helps stabilize long telephoto shots. However, image sharpness at extreme zoom ends softens slightly, typical of superzoom optics.

• Sony RX1: Sports a prime 35mm f/2.0 lens crafted with Zeiss optics, delivering stunning sharpness, contrast, and minimized distortion across the frame. The fast aperture enables excellent subject isolation and low-light capability but sacrifices zoom flexibility.

Personally, I find the RX1’s lens an optical gem, ideal for portraits, street photography, and environmental landscapes. The HX400V’s lens is the ultimate all-in-one travel companion when you need to capture everything from wide scenes to distant wildlife without swapping lenses.

Screen and Viewfinder Experience

The HX400V’s 3-inch tilting LCD with 921k-dot resolution allows comfortable framing in the field, even from awkward angles. Its electronic viewfinder fills the eyepiece with a clear, though modest, image, aiding stability.

The RX1 has a fixed 3-inch 1229k-dot Xtra Fine TFT LCD, sharper and more detailed but lacks articulation. The RX1 does not include a built-in EVF but offers an optional optical viewfinder for precise composition.

For photographers who rely heavily on viewfinder shooting, the HX400V’s integrated EVF and articulating screen provide an edge in flexibility and framing.

Battery Life and Storage

• Sony HX400V: Uses NP-BX1 battery rated at around 300 shots per charge. Supports SD cards along with Memory Stick formats.

• Sony RX1: Also uses NP-BX1 but rated slightly lower at 270 shots per battery. Storage includes SD cards and Memory Stick as well.

In practical testing, battery life on both models is sufficient for a day’s casual shooting, but heavy use of zoom or live view can drain the HX400V faster. Carrying spare batteries is recommended for extended sessions.
