Olympus PEN-F vs Olympus Stylus Tough TG-850 iHS: An Expert Comparison to Find Your Perfect Creative Companion

When stepping up your photography game or finding a reliable travel sidekick, Olympus offers an intriguing pair to consider: the PEN-F, a vintage-inspired advanced mirrorless system launched in 2016, and the TG-850 iHS, a rugged compact waterproof camera from 2014. On paper, these two reflect Olympus’ different approaches - one sharp and refined, the other tough and ready for adventure.

Having spent years testing both rangefinder-style mirrorless cameras and tough compacts across real-world scenarios, we've put these two through their paces in depth. Here’s an authoritative, hands-on comparison to unravel how each performs across photography disciplines, technology, and user experience. Whether you’re a seasoned pro or an enthusiastic beginner, this guide will help you find the right fit.

A Look at the Cameras’ Core Identities: Form, Features, and First Impressions

First, let’s understand what these cameras bring visually and physically, as this often shapes your creative workflow.

The PEN-F clearly targets photographers looking for a tactile, customizable experience, combining a heritage-inspired body with modern mirrorless versatility. Its relatively compact size and 427g weight feel balanced in hand, especially with a quality Micro Four Thirds lens attached.

In contrast, the TG-850 iHS excels in portability and ruggedness. At nearly half the weight and smaller dimensions, it’s designed to survive harsh environments like underwater shoots, winter sports, or dusty trails - something the PEN-F cannot handle without extra care.

Sensor and Image Quality: Micro Four Thirds vs 1/2.3" BSI-CMOS

The heart of any camera’s imaging ability lies in its sensor and processor. Let’s dive deep into the technical specs and how they translate into image quality.

From a technical perspective and extensive image testing, the PEN-F’s larger Micro Four Thirds sensor coupled with the TruePic VII processor delivers far superior image quality. The sensor size difference is significant - roughly eight times more surface area on the PEN-F’s sensor - which means better dynamic range, less noise at higher ISOs, and richer color depth.

The TG-850’s smaller 1/2.3” sensor limits its performance, especially in low light or complex lighting situations. It does handle daylight shots well and offers a broad zoom range suitable for casual snapshots, but noise levels increase quickly in shadows or at higher sensitivities.

Autofocus and Speed: Tracking, Face Detection, and Responsiveness

Autofocus reliability and speed are vital for capturing sharp images, especially when subjects move or lighting is challenging.

Olympus built the PEN-F’s autofocus system to accommodate both stills and video creators who demand precision. The 81 contrast detection points and built-in face detection deliver sharp subject focus even under complex conditions. It also offers useful focus bracketing and stacking features - ideal for macro and landscape photographers looking for razor-sharp depth of field through post-processing.

The TG-850 iHS autofocus is simpler and primarily contrast-based, with face detection to assist casual portraits. It doesn’t support manual focus or advanced focus modes. Its 7 frames per second burst rate is respectable for a compact but can’t match PEN-F’s responsiveness and tracking accuracy for fast-moving subjects like wildlife or sports.

Ergonomics, Control Layout, and User Interface

How a camera feels in your hands and how easily you can change settings impacts creative flow dramatically. Ergonomics are often overlooked but crucial for photographers planning extended use.

• PEN-F:

  • Classic rangefinder body with retro dials for shutter speed, ISO, and exposure compensation.
  • Top LCD display for quick settings overview.
  • Fully articulated 3-inch touchscreen LCD allows flexible framing including Vlogging angles.
  • Electronic viewfinder with 100% coverage and 0.62x magnification for bright, clear previews.
  • Illuminated buttons missing but layout is intuitive and customizable.

• TG-850 iHS:

  • Compact, grip-friendly body optimized for one-hand shootability.
  • No electronic viewfinder; relies solely on rear TFT LCD (tilting but non-touch).
  • Limited physical controls reflecting its simpler operation and focus on durability.

The PEN-F shines in usability for enthusiasts who want direct tactile control without digging through menus. Its touch LCD and EVF combo also cater well to photographers and video creators needing quick setup changes on the fly.

The TG-850 iHS opts for ease and ruggedness over customization. While simple menus and clearly labeled buttons lower the entry barrier for casual users or rugged environments, advanced photographers might find the control options restrictive.

Lens Compatibility and Zoom Versatility

Olympus PEN-F benefits from the Micro Four Thirds ecosystem, one of the most extensive lens lineups available today:

• Over 100 native lenses, from fast primes (f/1.2) to ultra-wide, telephoto zooms, macros, and specialty lenses.
• You can get Olympus’s own M.Zuiko lenses or third-party options from Panasonic, Sigma, and others.
• The 2.1x crop factor is standard for Four Thirds sensors, meaning a 25mm lens on PEN-F behaves equivalently to ~50mm on full frame.

The TG-850 iHS carries a built-in 21-105mm equivalent lens with a modest aperture range (f/3.5 to f/5.7), catering to everyday use:

• 5x zoom gives good framing flexibility from wide landscapes to moderate telephoto.
• No possibility to change or upgrade lens.

This discrete zoom range suits travel snapshots, underwater photography, and casual recording - no lens swapping, just point and shoot.

Durability and Weather Sealing: Studio vs Adventure

One of the TG-850’s biggest strenghts lies in its rugged construction:

• Fully waterproof down to approximately 15m (50 feet).
• Dust, shock, crush, freeze resistant - built for tough conditions.
• Compact design fits easily in pockets or bags for hikes, beach days, and extreme sports.

In contrast, the PEN-F lacks any weather sealing or environmental resistance. It demands more care and ideal shooting conditions or protective gear when outdoors.

Video Performance and Creative Flexibility

Videographers will notice stark differences:

PEN-F’s sensor-based 5-axis stabilization delivers smoother handheld video footage and greater freedom to shoot handheld in low light or while moving. The fully articulating touchscreen is a boon for vloggers framing themselves.

The TG-850, while offering optical stabilization and decent 1080p video, lacks external audio inputs and features expected by advanced video users. It fulfills casual video needs well but isn’t designed for professional-level projects.

Battery Life and Storage: Practical Aspects

Despite their differing sizes, both cameras offer similar battery endurance:

• PEN-F: Approx. 330 shots per charge using the BLN-1 battery pack.
• TG-850 iHS: About 330 shots per charge with LI-50B battery pack.

Both cameras utilize single SD/SDHC/SDXC card slots; however, the TG-850 also includes internal memory for emergency backups. The PEN-F, with more demanding imaging systems, can benefit from carrying spare batteries for long sessions.
