Pentax X-5 vs Sony RX100 VI

Pentax X-5 vs Sony RX100 VI: Which Bridge Camera or Large-Sensor Compact Wins Your Next Shoot?

When it comes to choosing a camera that balances reach, image quality, and versatility, the choices aren’t always straightforward. Today, I’m putting two very different beasts head-to-head: the long-established Pentax X-5, a bridge superzoom with a whopping 26x zoom, and the sleek Sony RX100 VI, a premium large-sensor compact packing a 24-200mm lens and blazing fast tech. I’ve personally tested thousands of cameras over my 15+ years behind the viewfinder, and these two models reveal an interesting story about evolving photography demands.

Let’s dive deep and see how these cameras perform across genres, tech specs, and real-world usability so you can pick the right one for your style - and budget.

Breaking Down the Bodies: Size, Handling & Ergonomics

Right off the bat, the first noticeable difference is size and heft. The Pentax X-5 is a fairly hefty bridge camera, weighing in at approx. 595 grams and a bulbous 119x86x107 mm frame, exuding that classic "SLR-like" grip. It feels substantial and secure in the hand, which some will love, especially if your preference skews towards something that feels like a DSLR without the lens changes.

On the other hand, the Sony RX100 VI is a marvel of compact engineering, roughly half the weight at 301 grams and significantly more pocketable at 102x58x43 mm. This really fits the bill of ‘large sensor compact’ - small enough to slip into a jacket pocket yet maintaining solid, purposeful ergonomics.

Ergonomically, the X-5’s physical controls cater more to beginners and casual shooters, with a more straightforward dial layout and dedicated buttons. The Sony RX100 VI amps things up with a thoughtfully placed, tilting touchscreen, higher-resolution EVF, and more refined control layout - a clear sign it’s engineered with enthusiasts in mind who demand direct access to manual settings at speed.

The top-view comparison reveals the RX100 VI’s advantage with its multifunctional dials and touchscreen that enable quicker adjustments, while the X-5 keeps things simpler and less customizable. For someone shooting fast action or busy street scenes, the Sony’s control responsiveness wins out. But if you prefer a no-fuss grip and minimal menus, the Pentax holds its own.

Sensor Size & Image Quality: Big Impact from a Small Difference

Here’s where things truly diverge - sensor technology and resulting image quality.

The Pentax X-5 sports a tiny 1/2.3" sensor (~27.7 mm²) with 16 megapixels. This is the same sensor size used in many point-and-shoots and compact superzooms of that era. While respectable for casual snaps and telephoto reach, it’s inherently limited in dynamic range, noise control, and color depth compared to larger sensors.

Enter the Sony RX100 VI, boasting a much larger 1” sensor (116.16 mm²) with 20 megapixels. This translates to almost 4x the surface area capturing light compared to the Pentax, which you’ll immediately see reflected in image clarity, low-light performance, and tonal gradation.

When I test cameras, sensor size is always a foundational metric I check alongside lab-based DxOMark scores, plus my own field experience. The RX100 VI’s larger sensor means less noise at ISOs beyond 1600, better rendering of subtle skin tones in portraits, and more detail when cropping landscapes. The Pentax X-5, while decent at ISO 100-400, starts showing noise and smudging above ISO 800 quite rapidly.

To be fair, the X-5’s sensor is paired with a very long zoom range, so compromises are expected. Still, if you want detailed images or plan to print or crop heavily, the RX100 VI is far ahead here.

Viewfinders and LCD Displays: Framing Your Shots with Confidence

Both cameras feature EVFs and tilting rear LCDs, but their execution differs widely.

The Pentax X-5 offers a 0.23 million-dot EVF that covers the scene roughly, and a 3-inch tilting LCD with a low-resolution 460k dot display. This feels dated today - especially noticeable in bright sunlight where visibility fades. It lacks touchscreen functionality, which can frustrate younger shooters used to swiping and tapping to set focus points or check menus.

In comparison, the Sony RX100 VI sports a whopping 2.36-million-dot OLED EVF with 100% coverage and 0.59x magnification, plus a 3-inch tilting touchscreen with 1.23 million dots. This combination facilitates precise manual focus, touch-to-focus, and quick review with accurate exposure previews.

For real-time framing, the RX100 VI’s EVF ensures little lag and crystal-clear compositional accuracy. The touchscreen accelerates focus point changes, especially useful in street or wildlife photography. The X-5's more rudimentary screen and EVF are serviceable but can hinder fast-paced shooting or intricate composition.

Autofocus Performance: Hunting or Pinpoint Precision?

Let’s talk autofocus - arguably the make-or-break factor for many shooters.

The Pentax X-5 employs a contrast-detection AF system with 9 focus points and face detection; it offers single, tracking, and multi-area modes but notably lacks phase detection or more sophisticated hybrid systems. This results in sluggish focus acquisition in low light and during fast-moving subjects.

The Sony RX100 VI, however, leverages a hybrid AF system with 315 phase-detect points covering most of the frame alongside contrast detection, plus Eye AF for humans (though no animal eye AF). Autofocus is lightning fast, often locking within a fraction of a second even in tricky lighting, and continuous tracking is very reliable.

This frankly makes the RX100 VI a far better candidate for wildlife, sports, or street shooters who need to freeze dynamic action. The X-5’s slow and sometimes “hunting” AF makes it less suited for such demanding scenarios, best reserved for more static subjects or casual photography.

Lens Versatility & Zoom Range: Telephoto Dreams vs Balanced Zoom

Now, the Pentax X-5 boasts an incredible 26x zoom lens spanning 22-580mm (equivalent), with aperture varying from f/3.1-5.9. This monstrous range gives you brute telephoto reach, ideal for distant wildlife or sports events - no lens swaps required.

Conversely, Sony’s RX100 VI offers a shorter 24-200mm zoom but with a faster aperture range of f/2.8-4.5, providing a brighter lens especially at wide angles and short telephoto lengths. The lens quality is also noticeably sharper edge-to-edge, thanks to modern optics.

It’s a classic trade-off: the X-5 grants you reach that can capture otherwise unreachable subjects, but optical sharpness and aperture suffer at the extremes. The RX100 VI sacrifices extreme telephoto but gives you better all-around image quality, especially for portraiture or landscapes, where edge sharpness and bokeh quality matter.

Shooting Experience Across Photography Genres

Portrait Photography

The RX100 VI’s larger sensor coupled with a wider max aperture translates to creamy bokeh and more pleasing rendering of skin tones. Its excellent eye detection AF locks on quickly and maintains focus, allowing you to get portraits with sharp eyes and beautiful background separation.

The X-5, with smaller sensor and slower aperture, struggles to isolate subjects due to limited depth-of-field control. Its face detection works but lacks eye AF, making portraits softer and less engaging.

Landscape Photography

The Sony’s superior sensor delivers better dynamic range crucial for landscapes, capturing deeper shadows and better highlight retention. Plus, its higher resolution enables more cropping flexibility. The X-5’s lower resolution and smaller sensor mean more noise in shadows and less fine detail.

Neither camera is weather sealed, though, so shooting in challenging conditions demands care.

Wildlife Photography

The Pentax X-5's massive zoom reach gives an edge for birders or casual wildlife fans. However, autofocus speed and tracking struggles become a bottleneck - sharp focus on moving animals is not guaranteed.

The RX100 VI, with swift AF and decent telephoto reach up to 200mm, excels for wildlife in moderate conditions but might fall short on distant birds or fast action too far away.

Sports Photography

Here, the RX100 VI steals the show with 24fps burst shooting and reliable AF tracking, letting you nail fast sequences. The X-5’s 10fps burst sounds good on paper but AF lag hampers usefulness.

Low light is another story: the RX100 VI handles it better thanks to sensor and lens advantages.

Street Photography

Compact and discreet, the RX100 VI is perfect for candid street photography, aided by touchscreen controls and fast AF. Its silent electronic shutter mode ensures no shutter noise, a huge plus.

The X-5 feels a bit cumbersome and noisier. It’s less portable and less stealthy.

Macro Photography

The Pentax X-5 offers a close macro focus range down to 1 cm, which is impressive at that zoom range and sensor size level. The Sony's closest focusing distance is 8 cm - a good but less extreme macro.

Both cameras lack focus stacking features but stabilize fairly well for handheld macro shots.

Night and Astro Photography

The RX100 VI’s larger sensor and ISO 12800 (boosted to 25600) capability ensure cleaner night shots and better star photography. Electronic shutter up to 1/32000s opens creative exposure possibilities.

The X-5’s ISO tops at 6400 with info missing about boosted modes. Noise becomes an issue above 800 ISO, limiting night potential.

Video Recording: Quality Matters

Pentax X-5 records full HD at 30fps in Motion JPEG format, which is dated and produces large files with less compression efficiency. No microphone input or advanced framings make it suited for occasional clips rather than serious video work.

Sony RX100 VI goes full 4K UHD at 30fps with XAVC S codec, offering crisp detail and better post-processing flexibility. It also provides slow-motion Full HD at 120fps, making it more attractive for hybrid shooters. Unfortunately, it lacks microphone and headphone jacks, which pros might find limiting.

Battery and Storage: Practical Considerations

The Pentax X-5 runs on 4 AA batteries, which is convenient for travel since they’re replaceable anywhere. It offers about 330 shots per charge - reasonable but not stellar compared to modern standards.

Sony RX100 VI uses a proprietary NP-BX1 lithium-ion battery with around 240 shots per charge, less durable but rechargeable via USB, promoting on-the-go top-ups.

Both cameras support SD cards, but Sony’s compatibility extends to Memory Stick formats as well.

Connectivity: Keeping Up With the Times

Pentax’s Eye-Fi card compatibility lets you wirelessly transfer images, but it’s an older tech now largely replaced by integrated Wi-Fi standards.

Sony makes wireless connectivity a breeze with built-in Wi-Fi, Bluetooth, and NFC - enabling remote shooting, quick transfers, and mobile app control out of the box.

Build Quality and Weather Resistance

Neither the Pentax X-5 nor Sony RX100 VI offers environmental sealing - meaning you should avoid heavy rain or dusty conditions. The RX100 VI’s robust metal chassis feels more premium and durable despite its compact size, whereas the X-5’s predominantly plastic body gives a slightly less solid impression.

Price and Value: What You Get for Your Money

The Pentax X-5 currently sells for around $230, making it a budget superzoom option with respectable features for casual shooters focused on reach.

The Sony RX100 VI, priced near $1200, is aimed at enthusiasts and professionals wanting a compact secondary camera or a primary for travel and street use without compromising image quality.
