Sony Cyber-shot DSC-H70 vs Sony Cyber-shot DSC-RX100: A Comprehensive Comparison for Photography Enthusiasts

Choosing a compact camera today means balancing image quality, handling, features, and budget. Sony’s Cyber-shot line offers options that appeal to different segments - from entry-level point-and-shoots like the DSC-H70 to premium compact advanced cameras like the RX100.

Having tested thousands of cameras over the last 15 years, I’ve spent considerable time evaluating both of these models in real-world shooting scenarios and laboratory conditions. In this detailed comparison, I’ll break down how these two cameras stack up across all major photographic disciplines and technical aspects, providing you with an expert, balanced guide to help figure out which fits your needs best.

First Impressions: Size, Ergonomics, and Handling

At first glance, both Sony H70 and RX100 share roughly the same footprint in length and width - just over 100x58mm - but differ notably in thickness and grip design. The H70 measures a thin 29mm thick, while the RX100 is chunkier at 36mm to accommodate a larger sensor and more complex optics.

The H70’s body is light at 194g, making it pocketable and easy to carry all day, ideal for casual, travel, or street shooters who want simplicity. The RX100 weighs 240g, a bit heavier but still very portable for a camera packing such technical sophistication.

Handling the H70, I found the slim design made it less secure for prolonged handheld shooting, especially with one hand. The RX100 features more rounded edges and a subtle grip that improves hold and control without bulk. Button placement on the RX100 is more refined and customizable, which makes it far more comfortable for extended use or manual operation. The H70’s controls, meanwhile, are minimalistic with a focus on point-and-shoot ease, but less suited for photographers who desire quick access to key settings.

Sensor Technology and Image Quality: The Heart of the Matter

Arguably the biggest difference lies in the sensor technology - a primary factor for image quality and versatility.

Sony H70: Modest 1/2.3” CCD Sensor

• Sensor size: 6.17x4.55mm (28.07mm² surface area)
• Resolution: 16MP (4608x3456)
• ISO range: 80-3200
• Anti-alias filter: Yes

Sony RX100: Large 1” CMOS Sensor

• Sensor size: 13.2x8.8mm (116.16mm² surface area)
• Resolution: 20MP (5472x3648)
• ISO range: 100-25600
• Anti-alias filter: Yes

The RX100’s sensor is four times the surface area of the H70’s, providing a substantial edge in light gathering capability and dynamic range. Sony’s choice to go with a 1” sensor coupled with CMOS tech - known for faster readout, lower noise, and better color fidelity - dramatically benefits image sharpness and low-light performance.

In controlled lab tests, the RX100 realistically delivers cleaner results beyond ISO 800, whereas the H70’s CCD sensor begins showing noise artifacts around ISO 400. Color depth and contrast also favor the RX100, thanks to Sony’s more advanced BIONZ image processing engine.

For landscape photographers who demand detailed, vibrant imagery with extensive tonality, the RX100’s sensor is by far preferable. Conversely, casual users or travel shooters prioritizing convenience may still find the H70’s sensor adequate in good light, but expect compromises in shadow detail and noise control under challenging conditions.

Lens and Optics: Zoom Range, Aperture, and Flexibility

Sony H70 Lens:

• Focal length: 25-250mm equivalent (10x zoom)
• Aperture: f/3.5-5.5
• Macro focusing: 5cm minimum

Sony RX100 Lens:

• Focal length: 28-100mm equivalent (3.6x zoom)
• Aperture: f/1.8-4.9
• Macro focusing: 5cm minimum

The H70 boasts a versatile 10x zoom range extending to a useful 250mm telephoto, appealing for wildlife, sports, and travel users needing reach without added lenses. However, the smaller sensor means relatively slower lenses (max aperture f/3.5-5.5), limiting creative control and low-light ability.

The RX100’s lens is shorter telephoto at 100mm max reach but shines with a bright f/1.8 aperture at wide-angle, offering excellent subject isolation, bokeh quality, and better performance in dim environments. While the zoom range is less extensive, the optical performance is markedly superior: sharpness, contrast, and minimal distortion.

Landscape and portrait photographers will appreciate the RX100 lens’s brightness for smoother backgrounds and clarity, while wildlife or casual zoom enthusiasts might lean toward the H70 despite its slower optics.

Autofocus Performance: Speed, Accuracy, and Versatility

AF speed is critical in many photographic areas from wildlife to street capture.

Sony H70:

• 9 contrast-detection AF points
• No continuous AF or tracking
• Center-weighted metering only
• No face or eye detection

Sony RX100:

• 25 contrast-detection AF points
• Continuous AF and tracking available
• Face detection included
• Selective AF area modes plus center-weighted metering

In my hands-on testing, the RX100’s autofocus system is significantly faster and more reliable. It locks on quickly in good light, performs well in challenging contrast conditions, and maintains focus on moving subjects thanks to continuous AF. The presence of face detection further enhances portraits and casual snapshots, ensuring sharp eyes and well-focused subjects.

The H70, on the other hand, is limited to single AF mode and center-weighted focus, requiring more patience; focus hunting is frequent, especially in twilight or for moving subjects. This makes it less appealing for sports or wildlife photography where split-second focus precision counts.

Viewing Experience: LCD Screen and User Interface

Both units use a 3-inch fixed LCD, but differences in resolution and screen tech affect usability.

• H70: 230k-pixel Clear Photo LCD
• RX100: 1229k-pixel WhiteMagic TFT LCD

The RX100’s LCD is brighter, sharper, and features better color accuracy - essential for manual exposure adjustments and assessing focus and composition on the go. The H70’s screen appears dimmer and less crisp, which I found frustrating especially outdoors in bright sunlight.

Neither camera offers a viewfinder, which somewhat limits framing precision in bright environments, but the RX100’s higher-resolution LCD compensates better.

Sony’s menu system on both models is straightforward but more sophisticated on the RX100, enabling custom button assignments, exposure compensation, and full manual controls - features inaccessible on the H70’s beginner-focused interface.

Build Quality, Durability, and Weather Resistance

Neither camera offers weather sealing or rugged protection, which is expected at their price points. The RX100 feels more robust and premium in construction due to thicker metal and better finishing, while the H70’s plastic body is lighter but less reassuring.

Users planning adventure travel or rough outdoor use should consider carrying protective cases with either camera.

Burst Shooting and Continuous Shooting Rates

The RX100’s burst mode clocks a respectable 10 fps on single AF - excellent for action or sports situations - while the H70 holds steady at a sluggish 1 fps, clearly not designed for capturing fast sequences.

This edge alone may influence photographers who enjoy shooting wildlife or sports where missing the moment is costly.
