Sony HX1 vs Sony RX1: A Hands-On Comparison from an Experienced Lensman

As a photographer who’s tested thousands of cameras over the last decade and a half, I often find that the most confusing comparisons are those between very different categories of cameras - and today’s match-up certainly fits that bill. We’re taking a close look at two notable Sony offerings from different eras and segments: the Sony Cyber-shot DSC-HX1, a small sensor superzoom bridge camera from 2009, and the Sony Cyber-shot DSC-RX1, a full-frame large sensor compact from 2013.

Although they both carry the Cyber-shot name, these cameras target very different users and shooting styles - which is precisely why a detailed, experience-based comparison is helpful for photographers aiming to make informed decisions beyond simple spec sheets.

Let me walk you through everything you need to know across genres, real-world use, and technology, with plenty of candid insights you won’t find in marketing fluff.

Size, Build & Handling - First Impressions Matter

Both cameras sport different design philosophies that reflect their intended audiences.

The HX1 looks like an SLR-style “bridge” camera - bulkier, with a pronounced grip and a long zoom lens out front. It feels robust in the hand, with plenty of manual controls visible at a glance. The RX1, by contrast, is a straightforward, minimalist compact with a fixed 35mm full-frame lens - no zoom, no gimmicks - designed more for discretion and portability.

Here’s a physical size comparison to give you perspective:

The HX1 is evidently chunkier, nearly twice as tall and deep as the RX1, which is slim and pocket-friendly.

Handling-wise, the HX1’s broader grip and piles of buttons are perfect for those who crave immediate control over settings - think photographers who want clubs for their thumbs. The RX1’s minimalism is a double-edged sword: fantastic for travel and street shooting due to its stealth, yet potentially limiting if you prefer knobs and wheels over menus.

Adding to this perspective, here’s the top view showing control layouts:

Bottom line on ergonomics: For someone who likes a camera that physically feels like a traditional shooter and affords fast access to dials - HX1 wins. For those valuing portability and discretion, RX1 is the clear champion.

Sensor Size & Image Quality – The Heart of the Matter

This section is where the two cameras part company drastically.

The HX1 uses a tiny 1/2.4" CMOS sensor with just 9 megapixels, an era-typical compromise for the extensive 20x zoom lens it sports (28-560mm equiv.). The RX1 features a full-frame 24MP sensor - the kind generally found in professional DSLRs and mirrorless cameras.

Check out the significant scale difference in sensor area:

The RX1’s 852mm² sensor dwarfs the HX1’s meager 28mm² chip, promising substantially superior image quality, especially in low light and for dynamic range.

I’ve run numerous side-by-side tests in real-world conditions: the RX1 delivers creamy, natural skin tones with excellent dynamic range - crucial for portraits and landscapes alike - whereas the HX1 exhibits images that look fuzzy and heavily noise-affected beyond ISO 400. The full-frame RX1’s 14.3 stops of dynamic range (per DxO Mark) allow for true-to-life shadows and highlights even under tricky lighting; the HX1’s smaller sensor just doesn’t keep up.

Because the HX1’s lens uses a smaller sensor area, it employs an effective 5.9x crop factor in the expressed focal length, but it’s still no substitute for the RX1’s native full-frame look. This means RX1 users get gorgeous subject separation and bokeh, whereas HX1’s aperture and sensor combo limit defocus effects.

For image quality junkies:

• RX1 offers true high-res, pro-level image quality and wider ISO usability.
• HX1 is fine for casual shooting or zoom convenience but will disappoint in serious work.

Autofocus & Performance: Speed, Precision, and Tracking

Autofocus technology has evolved considerably between these models.

The HX1 employs a 9-point contrast-detection AF system, which performs adequately in good light but struggles in dimmer environments or fast-moving subjects. It lacks continuous AF or advanced tracking, so sports or wildlife photographers will find it sluggish and prone to missed shots.

The RX1, although also relying on contrast detection with 25 points, has face detection and continuous AF tracking capabilities, enhancing accuracy for portraits and action - though it’s no speed demon compared to modern mirrorless cameras. Still, it feels noticeably more precise and reliable, especially when paired with the prime 35mm lens.

Burst rates tell a similar story:

• HX1 shoots 10 fps in continuous mode (but with lower resolution and slow buffer clearing),
• RX1 offers a steadier 5 fps, with more consistent image quality and better file handling.

Given their respective launch years, autofocus performance is not a surprise, but it impacts the types of photography each is suited for.

Verdict on AF:

• Sports and wildlife shooters will find neither camera top-tier today - but RX1 is the better performer overall.
• Portrait and street photographers will appreciate RX1’s face detection and AF accuracy.

Display and Viewfinder: How You See Your Shot

Both models feature 3” LCDs but with differing resolutions and articulation.

The HX1 employs a 230k-dot tilting LCD, handy for shooting from tricky angles but lacking detail and brightness. Its electronic viewfinder is low-res, offering basic framing.

The RX1’s screen is a fixed, 1229k-dot “Xtra Fine TFT LCD” - a much sharper and more pleasant viewing experience, though you lose tilt functionality. The RX1 has no built-in electronic viewfinder but supports an optional optical viewfinder accessory, which some photographers swear by for precision framing.

Here’s a direct comparison:

Visually, the RX1’s screen shows cleaner, sharper previews, essential when reviewing sharpness and exposure in the field.

Lens, Zoom, and Versatility: Which One Works for You?

One of the most obvious divides lies in the fixed lens specs:

• HX1: 28-560mm equivalent 20x zoom with max aperture f/2.8–5.2
• RX1: 35mm prime f/2.0 aperture

The HX1 is an all-in-one superzoom partner. Its macro focus down to 1cm is impressive, letting you explore close-ups without extra gear. If you want the convenience of zooming from wide to super-telephoto, this bridge camera is a solid companion, particularly for casual travel or family events.

The RX1’s fixed 35mm lens means commitment - you have the classic “walk-around” focal length for reportage, street photography, landscapes, and environmental portraits. The f/2.0 aperture allows excellent subject isolation and usability in dim settings but no zooming flexibility.

So, how to choose?

• Zoom lovers, videographers needing framing control, or casual shooters: HX1.
• Purists, street/documentary artists, or those chasing ultimate sharpness and subject separation: RX1.

Real-World Sample Shoots: Image Quality in Action

Technical specs aside, the proof is in the photographs. I prepared a gallery showcasing images from both cameras across everyday shooting scenarios.

Notice the RX1’s crispness, excellent color rendition, and sharpness even in challenging light, versus the HX1’s softer, noisier photos. Portrait skin tones look warmer and more natural on RX1, while HX1’s long zoom shots sometimes suffer from detail loss far out at 560mm.

Specialized Disciplines: Can These Cameras Keep Up?

Let’s break down how the HX1 and RX1 perform in specific genres:

1. Portrait Photography:
   RX1 shines with face detection, natural skin tones, and creamy bokeh thanks to its full-frame f/2 lens. HX1 lacks eye-detection and struggles with background blur.

2. Landscape Photography:
   RX1’s superior sensor, dynamic range, and sharp fixed lens deliver stunning results. HX1 is limited by sensor size and lens sharpness but offers zoom flexibility.

3. Wildlife Photography:
   HX1’s zoom gives reach but suffers from slow AF and small sensor noise at higher ISO. RX1’s autofocus and lens are less ideal for distant subjects.

4. Sports Photography:
   Neither excels, but HX1’s faster burst rate matters; it’s hampered by AF lag.

5. Street Photography:
   RX1’s minimal size, discretion, and quick AF make it a top choice. HX1 is too bulky and conspicuous.

6. Macro Photography:
   HX1’s 1cm macro focus is handy; RX1 offers no dedicated macro.
