Pentax X-5 vs. Sony Cyber-shot TX55: A Hands-On Comparison of Two Compact Cameras for Different Photographers

Choosing the right compact camera can feel overwhelming given options that vary widely in design, features, and performance. In this article, I’ll dive deeply into two distinct models - the Pentax X-5, a superzoom bridge camera released in 2012, and the Sony Cyber-shot TX55, a sleek ultracompact from 2011 - to help you understand their real-world strengths, technical underpinnings, and use-case suitability. Drawing on my years of extensive hands-on testing of hundreds of cameras, this comparison will give you clear, trustworthy insights grounded in practical experience.

Getting to Know the Cameras: Physical and Design Differences

Before diving into image quality and functionality, I like to start with ergonomics and handling - aspects that directly affect your shooting comfort and experience.

Pentax X-5: This bridge-style camera features a DSLR-like body with a hefty grip designed for stable shooting, especially helpful at its extreme zoom range. The 119x86x107 mm size and 595-gram weight offer robust heft, which I appreciated for prolonged shooting sessions outdoors or in wildlife environments. It sits comfortably in hand and offers tactile control dials and buttons.

Sony TX55: In contrast, the TX55 is an ultracompact marvel, measuring just 93x54x13 mm and weighing a mere 109 grams. Its slim form factor means it slips perfectly into any pocket or purse, making it highly convenient for grab-and-go shooting or street photography. Handling is minimalistic - it lacks a physical viewfinder and relies on a touchscreen interface - but that can feel limiting if you’re used to traditional button controls.

The image above highlights these stark differences. The Pentax feels like a serious photographic tool, while the Sony prioritizes portability. Your choice here hinges on prioritizing comfort and versatility versus travel-friendliness and stealth.

Control Layout and Interface

Looking at the control scheme, the Pentax offers traditional DSLR-style buttons and a top dial for quick exposure compensation, mode switching, and focus options. This layout proved intuitive during my testing, especially when switching rapidly between manual, aperture priority, and shutter priority modes.

Sony’s TX55, designed for simplicity, uses a fixed 3.3-inch OLED touchscreen with 1230k-dot resolution for image review and settings. It completely forgoes a physical viewfinder or extensive manual controls, which means you’re dependent on touchscreen menus and face-focused autofocus. I found this efficient for casual shooting but less flexible for advanced users seeking quick manual overrides.

Sensor and Image Quality: Core Differences in Picture Making

Both cameras feature 1/2.3-inch BSI-CMOS sensors with 16MP resolution, but their image quality diverges due to sensor tuning, image processing, and lens designs.

Resolution and Detail

Both deliver a maximum image size of 4608x3456 pixels, sufficient for 8x10 prints and web sharing. The Pentax’s sensor area is roughly 27.72 mm² versus 28.07 mm² for the Sony - practically identical and typical for compact cameras of their era.

In practice, I noticed the Pentax’s lens sharpness suffered slightly at the telephoto end, especially beyond 400mm equivalent focal length, which is common given its immense 26x zoom. The Sony’s lens, with a shorter zoom range (5x from 26-130mm equivalent), showed consistently better corner-to-corner sharpness within its focal length.

Dynamic Range and Noise

Low-light and dynamic range are where sensor and processor design becomes crucial. The Pentax X-5 peaks at ISO 6400, while the Sony caps at ISO 3200. However, noise levels on both models start becoming significant above ISO 800.

From my extensive ISO testing, the Sony’s BIONZ processor produces cleaner files at ISO 800 and 1600, with less luminance noise and better color retention compared to the Pentax. The Pentax’s files are noticeably noisier beyond ISO 400, and dynamic range compression causes shadow detail loss.

Color Rendition and White Balance

The Pentax benefits from custom white balance options and face detection autofocus that aids skin tone accuracy during portraits. The Sony also offers custom white balance plus WB bracketing, a boon for tricky lighting, but lacks face detection autofocus, which can cause skin tones to appear less natural in portraits.

Viewing Experience: Screens and Viewfinders

How you frame and review your shots deeply influences you’re shooting enjoyment and accuracy.

• Pentax X-5 offers a 3-inch, 460k-dot tilting LCD and a 230k-dot electronic viewfinder (EVF). The tilting screen is versatile for shooting at high or low angles, and the EVF is handy in bright sunlight. Though modest resolution by today’s standards, I found the EVF invaluable for grip and composure stability.

• Sony TX55 relies solely on its 3.3-inch, 1230k-dot XtraFine OLED touchscreen - no viewfinder available. The OLED screen colors are vivid with excellent contrast, which I appreciated for playback and focusing, but its fixed position requires wrist maneuvers for creative angles.

Autofocus and Shooting Performance

Autofocus Systems

• Pentax X-5 uses 9 contrast-detection AF points with face detection. Though contrast autofocus is slower compared to phase detection, the Pentax felt snappy enough for casual wildlife or travel photography if you gave it adequate light.

• Sony TX55 employs 9 contrast-detection AF points too but lacks face and eye detection. AF was quick and accurate in good light but struggled more in dim situations without subject tracking assistance.

Neither camera supports continuous AF during burst shooting, which limits action photography.

Burst Shooting and Shutter Speeds

Both cameras shoot at 10 fps maximum burst speed, an impressive figure for compacts. However, buffer depth and image quality (JPEG only, no RAW) limit sustained high-speed shooting.

Shutter speed range sits between 1/4s to 1/1500s on Pentax and 1/30s to 1/1600s on Sony. The Pentax’s longer slow shutter mode is useful for low-light effects; Sony’s shutter floor can become a constraint in very low light without boosting ISO.

Lens and Zoom: Focal Range and Versatility

Pentax X-5: The Superzoom Workhorse

• Focal length: 22-580mm equivalent (26x zoom)
• Aperture: f/3.1 at wide, f/5.9 at tele
• Macro focusing: 1cm minimum

This range gives enormous versatility - from wide-angle landscapes to distant wildlife or sports. Image stabilization is sensor-shift based, helping to reduce blur especially at long zooms during handheld shooting. The close macro focus is impressive for detailed close-ups.

Sony TX55: Sleek, Moderate Zoom

• Focal length: 26-130mm equivalent (5x zoom)
• Aperture: f/3.5 to f/4.8
• Macro focus: 3cm minimum

The TX55’s compact lens favors portability but sacrifices reach. I found this lens superb for street and travel photography but limiting if you want to capture distant sports or wildlife. Optical image stabilization in Sony helps handheld sharpness but less so at maximum zoom.

Build Quality and Durability

Neither model offers environmental sealing, weather resistance, or ruggedized durability. The Pentax weighs significantly more, reflecting its robust plastic and rubberized grips. The Sony, due to size constraints, feels more delicate and susceptible to scratches and impacts.

Battery Life and Storage

• Pentax X-5: Uses 4 AA batteries and claims ~330 shots per charge. I found that AA batteries are convenient but heavier and less cost-effective long-term compared to rechargeables.

• Sony TX55: Powered by a proprietary NP-BN lithium-ion battery, offering ~250 shots per charge. Compact but less endurance for extended travel shoots.

Storage-wise, Pentax supports standard SD cards, while Sony takes microSD and Memory Stick Micro cards, slightly limiting media options.

Video Capabilities

Both cameras capture Full HD video but with different strengths:

• Pentax X-5: Full HD 1920x1080 @ 30fps, recorded in Motion JPEG format. Lacks microphone input or headphone jack. Stabilization is sensor-shift based but video is somewhat limited overall.

• Sony TX55: Supports 1080p @ 60fps, 1440x1080 @ 30fps, and various lower resolutions. Formats include MPEG-4 and AVCHD, providing more efficient compression and smoother video. HDMI output available but no external audio ports.

Sony’s faster frame rates and high-quality display make it more compelling for casual video shooters.
