Olympus 1s vs Sony RX100 IV: A Battle of Compact Versatility and Image Excellence

As someone who has put thousands of cameras through their paces - from rugged DSLRs to sleek compacts and everything in between - I’m always keen to see how manufacturers marry portability with performance. Today, we’re diving deep into a comparison between two pocket-sized powerhouses announced in 2015: the Olympus Stylus 1s (simply “Olympus 1s”) and the Sony Cyber-shot DSC-RX100 IV (hereafter “Sony RX100 IV”). Both are designed to appeal to enthusiasts who crave a compact camera with advanced features - but they come from different camps with distinct philosophies.

I personally tested these cameras across a varied range of photography genres and technical conditions to uncover real-world strengths and weaknesses. Whether you’re a landscape shooter needing dynamic range, a wildlife enthusiast chasing fast autofocus, or a street photographer seeking discretion, this comparison aims to help you choose the right tool for the job.

Size, Handling, and Ergonomics: Which Fits Your Grip and Style?

The Olympus 1s strikes me as a bold entrant in the “bridge camera” category - with a chunky, SLR-like physique featuring a grip designed for comfort and a broad control layout. In contrast, the Sony RX100 IV drastically prioritizes pocketability and sleekness, showcasing a compact strategy that fits snugly into smaller bags or even jacket pockets.

The Olympus weighs 402 grams with dimensions 116 x 87 x 57 mm, while the Sony is significantly lighter at 298 grams and smaller at 102 x 58 x 41 mm. This weight difference isn’t trivial: the 1s feels substantial and sturdy, almost like a mini DSLR, lending confidence during longer shoots. Meanwhile, the RX100 IV, though lighter, doesn’t feel cheap; its robust chassis and refined finish communicate premium craftsmanship.

When testing both cameras outdoors, I noticed the Olympus feels easier to hold steady - especially when zoomed in at its max focal length (300mm equivalent). The larger size accommodates larger hands and the thumb comfortably rests on the rear dial. The Sony RX100 IV suits discreet shooting styles - perhaps in street or travel scenarios - where you don’t want to draw attention or carry heavy gear.

Ergonomically, the control layout tells a similar story. Olympus’s top plate offers physical dials and buttons that veteran photographers will appreciate for quick access (aperture ring included - a nice touch for tactile control). Sony’s RX100 IV favors a cleaner design with fewer physical controls, prioritizing menu navigation through buttons and a control wheel. This can slow quick setting changes but still remains efficient once you get used to it.

The 1s includes an articulated touchscreen with 1040k-dot resolution, useful when composing at odd angles, whereas the RX100 IV sports a higher resolution 1229k-dot tilting LCD but - critically - without touch functionality. The latter is a tradeoff: touchscreen adds intuitive focus point selection but can be finicky outdoors.

Sensor and Image Quality: The Core of Your Shots

A substantial difference lies under the hood: the Olympus 1s uses a 1/1.7-inch BSI-CMOS sensor with 12MP resolution, while the Sony RX100 IV employs a much larger 1-inch BSI-CMOS sensor at 20MP resolution.

This sensor size disparity (Olympus sensor area roughly 41.5mm² vs Sony’s 116.1mm²) has substantial implications. Larger sensor size translates to improved light gathering, better signal-to-noise ratio, greater dynamic range, and enhanced detail retention - especially in challenging light.

The Sony’s 1-inch sensor is a class-leader among compacts, offering flexibility to shoot at higher ISOs with less noise and richer tonal gradations. In daylight and well-lit conditions, the Sony’s superior resolution of 5472 x 3648 pixels yields images with greater detail and improved cropping freedom.

In practical testing, shadow and highlight recovery were noticeably better in the RX100 IV files. Olympus’s 12MP sensor excels in delivering contrast-rich images but shows its limitation under dynamic scenes, with less latitude to pull details from shadows or bright areas. That said, Olympus’s sensor renders pleasant colors and handles JPEG processing well, thanks in part to their extensive color science experience.

Interface and Display: Composing Your Vision

Diving deeper into the user interface, both cameras include tilting LCDs around 3 inches in size. The Olympus’s touchscreen interface grants rapid AF point selection and menu navigation; I found this highly beneficial during macro and street photography scenarios where quick compositional adjustments matter.

Sony’s RX100 IV, while having a slightly higher-resolution screen and an excellent electronic viewfinder (EVF) boasting 2359k dots, lacks touchscreen capabilities. However, the EVF performance here can’t be overstated - the RX100 IV’s pop-up OLED EVF is sharp with excellent color fidelity, giving a DSLR-like shooting experience impressive for a compact camera.

Olympus’s EVF, with its lower 1440k-dot resolution, felt serviceable but less punchy and precise. It performs well in good light but shows some lag and grain in darker scenes.

Image Quality in Real-World Use: Testing Across Genres

To evaluate their photographic prowess, I shot test sequences covering various genres:

• Portraits: The Sony RX100 IV’s wider aperture of f/1.8 at the wide end (up to f/2.8 tele) excels at creating creamy bokeh and subject-background separation. Its eye-detection AF and face recognition were swift and accurate, producing sharp focus on eyes consistently. Olympus’s fixed f/2.8 aperture across its zoom range is respectable but doesn’t produce the same shallow depth of field effect at longer focal lengths. Face detection works but lacks eye priority.

• Landscapes: Here, dynamic range is king. The RX100 IV’s sensor shines with expanded DR, delivering images with richer tonal variation. Combined with a clean ISO 100 base, it’s excellent for capturing subtle cloud detail and shadow areas. Olympus’s smaller sensor limits DR, but thanks to an extended zoom, you can frame unique compositions from a distance. Both lack extensive weather sealing, so caution is warranted in rugged conditions.

• Wildlife: Telephoto reach favors Olympus (300mm vs Sony’s 70mm max optical zoom). Its 10.7x zoom lens lets you get far closer without changing gear. However, autofocus speed seems slower and huntier than the Sony’s snappy AF system. Shooting birds in flight highlighted Sony’s superior continuous AF tracking and 16fps burst speed compared to Olympus’s 7fps. If reach matters more than speed, Olympus has the edge.

• Sports: The RX100 IV proves superior, delivering fast continuous shooting with precise AF tracking and a mechanical shutter up to 1/2000 s, plus an impressive electronic shutter capable of 1/32000 s for fast action. Olympus’s 7fps rate is solid but can’t match Sony’s burst performance or tracking ability.

• Street: Compact size and discreet operation put Sony ahead here. Its small profile combined with silent shutter mode (thanks to electronic shutter) lets you shoot candid moments unobtrusively. Olympus’s larger body calls more attention and the shutter sound is louder. Also, Sony’s high ISO performance benefits low-light street shooting.

• Macro: Both cameras feature a 5cm minimum focus distance. Olympus’s optical image stabilization (OIS) shines here, reducing handshake at close range. Sony has built-in stabilization too, and its faster lens helps in dim lighting. I found Olympus’s tilting touchscreen enhanced manual focus precision in macro work.

• Night / Astro: The Sony RX100 IV wins hands down with superior high ISO behavior, lower noise, and longer exposure response - critical for astrophotography. Olympus’s sensor noise grows quickly beyond ISO 800, limiting its night usability.

• Video: Sony’s RX100 IV supports 4K UHD at 30p, unavailable on the Olympus which tops out at 1080p/30p. The RX100 IV also offers slow-motion 120fps HD suitable for creative video effects. Despite no mic or headphone ports on either, Sony’s video rendition is cleaner with better detail retention.

• Travel: Here the balance is tricky. Olympus’s longer zoom covers more focal lengths without swapping lenses, offering all-in-one convenience for sightseeing. Sony’s smaller size and lighter weight make it easier to carry around all day, but you sacrifice zoom range.

• Professional Work: Both cameras offer RAW shooting and manual controls, but neither rivals interchangeable-lens cameras for file quality or versatility. Sony’s superior sensor and 4K video make it a better secondary option for professional hybrid shooters.

Autofocus and Speed: Tracking Moments in Your Frame

I devoted significant testing time to evaluating autofocus (AF) performance - arguably one of the most critical factors for versatile photographers.

Olympus 1s relies on 35 contrast-detection AF points, covering a reasonable area with face detection technology but lacking phase-detect AF. While usable, I found it slower to lock focus in low contrast and dim conditions. Continuous AF tracking feels tentative during action sequences.

Sony RX100 IV utilizes 25 contrast-detection points, but with a refined algorithm delivering fast and accurate focus acquisition. While it also lacks phase detection, its responsive continuous AF is excellent during fast-moving subjects, aided by its 16fps burst speed.

Both cameras support manual focus with peaking aids, but Olympus’s touchscreen simplifies selecting focus points intuitively, especially useful in macro or busy street scenes.

Build Quality and Durability: Can They Keep Up?

Neither camera offers formal weather sealing or ruggedness for harsh environments - a significant consideration for outdoor photographers.

Olympus’s bigger body feels solidly constructed with reinforced polycarbonate and metal elements, while Sony RX100 IV carries a premium metal body that screams quality despite its small size.

Battery life differs notably: Olympus achieves approximately 450 shots per charge - excellent for a compact - and Sony around 280 shots, somewhat restrictive for a day-long shoot without spares.

Both use proprietary battery packs and single SD card slots. Olympus’s BLS-50 battery is a reliable performer, while Sony’s NP-BX1 is less enduring but lighter.

Lens Considerations and Zoom Ranges

With fixed lenses, you’re locked to certain focal ranges:

• Olympus: 28-300mm equivalent zoom (10.7x), constant f/2.8 aperture across zoom range. This is remarkable for low-light telephoto shots and macro photography.

• Sony: 24-70mm zoom (2.9x) with fast f/1.8–2.8 aperture, great for portraits and wide-angle scenic shots but limited telephoto reach.

If your photography involves distant subjects, Olympus’s reach offers a tangible benefit. Conversely, Sony’s faster lens optics with wider aperture provide richer background separation and better performance in dim light at wide angles.

Connectivity and Features: Sharing and Workflow

Modern cameras integrate connectivity to enhance post-shoot workflow. Both models offer wireless connectivity - Olympus uses built-in WiFi but lacks NFC or Bluetooth, while Sony adds NFC to simplify pairing but omits Bluetooth.

File format support is similar: both produce full raw (.ARW for Sony, standard RAW for Olympus) and JPEG outputs, compatible with all mainstream photo editing software.

On the video front, Sony clearly leads with UHD 4K and multiple frame rates, enabling professional-level video capture for vloggers or hybrid shooters. Olympus only provides Full HD (1080p) at 30fps, sufficient for casual use but limiting for advanced creators.

Pricing and Value: Which Camera Fits Your Budget?

At launch, Olympus 1s retailed for approximately $699, while the Sony RX100 IV was pricier at around $898. While these prices have fluctuated over time, the Sony commands a premium justified by sensor size, 4K video, and faster AF.

Your value proposition depends heavily on your priorities. For zoom flexibility and ergonomic handling in a bridge-style body - along with strong still-image quality - the Olympus is a compelling option.

If sensor size, image quality, video capability, and discreet portability top your list, the Sony RX100 IV represents a worthwhile investment despite the higher cost.
