Panasonic LS5 vs Sony A850: A Hands-On Comparison Between a Compact Casual and a Pro DSLR

In my 15 years of testing cameras - from pocket compacts to full-frame beasts - I’ve seldom seen two cameras more divergent in design philosophy and usage than the Panasonic Lumix DMC-LS5 and the Sony Alpha DSLR-A850. Both launched around the same era (2010-2011), yet targeting wholly different audiences. The Panasonic LS5 is a compact zoom camera focused on simplicity and portability, while the Sony A850 is a full-frame professional DSLR built for high-image-quality, versatility, and durability.

Having spent ample time with each in varied shooting scenarios, I'm excited to take you through a comprehensive, experience-driven comparison. You’ll find detailed technical analysis mixed with real-world observations across all major photography genres, insights into ergonomics, sensor performance, and workflow integration, plus clear recommendations tailored to your photography style and budget.

Let’s jump right in.

Size and Handling: Pocketable Convenience Meets DSLR Ergonomics

To kick things off, the Panasonic LS5 and Sony A850 couldn't be more different physically:

The Panasonic LS5 is a truly pocket-friendly compact - a featherlight 126 grams, measuring roughly 97×62×27 mm - ideal for casual shooters who want a versatile zoom without lugging heavy gear. I often slipped it into my bag or jacket pocket during city walks or holidays where minimalism was priority.

In contrast, the Sony A850 weighs 895 grams and measures a solid 156×117×82 mm. Its grip feels substantial, designed for extended handheld use. The DSLR’s rugged chassis is reassuringly built with magnesium alloy and includes weather sealing, making it a dependable travel and professional camera.

While the LS5's small size is a boon for travel convenience and street photography discretion, it compromises manual control and handling comfort. The A850’s weight and bulk are drawbacks if you need to roam light, but its ergonomics support complex setups, longer shooting sessions, and precise adjustments that serious photographers will appreciate.

Top Control Layouts: Minimalist vs. Pro-Level Customization

Looking at their top plates reveals their intended user base:

The Panasonic LS5's top controls are almost minimal - a shutter button, zoom lever, and power switch dominate. No mode dials for aperture or shutter priority, no customizable buttons, no exposure compensation. This simplicity works well for beginners or casual users who want straightforward point-and-shoot operation. However, advanced photographers will find it limiting, especially when trying to control depth of field or exposure creatively.

The Sony A850 sports a traditional DSLR layout with dedicated dials for shutter speed, aperture, exposure compensation, drive modes, and metering. Along with customizable buttons accessible without removing your eye from the viewfinder, this design reflects my experience using it in fast-paced environments where quick changes make the difference. For landscape, portrait, or sports situations, the tactile inputs are a godsend.

Sensor Size and Raw Image Quality: The Heart of Image Excellence

The sensor is arguably the most critical factor distinguishing these two cameras:

The Panasonic LS5 uses a modest 1/2.3 inch CCD sensor measuring about 6.08x4.56mm (27.72 mm²) with 14 megapixels. While that might sound respectable, in practice the small sensor size heavily impacts image quality, especially in low light and dynamic range. Noise climbs quickly past ISO 400, and detail is limited when cropping or printing large. Its fixed anti-aliasing filter reduces moiré but also softens fine textures.

Conversely, the Sony A850 boasts a full-frame 35.9x24mm CMOS sensor with 24.6 MP resolution. This sensor area is roughly 30 times larger than the LS5's, providing significantly higher sharpness, greater dynamic range, and much improved low-light capability. The Bionz processor complements by delivering clean, detailed RAW files up to ISO 3200 and even boosted ISO 6400 for emergencies, making it capable in night, astro, portrait, and landscape work.

In my side-by-side shooting of landscape scenes, the A850 consistently captured richer tonal gradations and retained details in the shadows and highlights that the LS5 missed entirely. The full-frame sensor's color depth (DxOmark score around 23.8 bits) supports natural skin tones and vibrant hues that stand apart from small sensor compacts.

Rear Screen and User Interface: Viewing, Reviewing, and Navigation

The screen is often overlooked but crucial for composition and image review:

Panasonic equips the LS5 with a 2.7-inch fixed TFT LCD at 230K dots. It’s adequate for framing casual shots but struggles under direct sunlight and lacks touch functionality or articulation. Menu navigation is simple, but slow, making quick settings changes cumbersome.

The Sony A850 offers a larger 3.0-inch “Xtra Fine” TFT LCD with 922K dots, providing sharp previewing and more accurate color. Though there's no live view mode, the menus are well organized with extensive customization and intuitive operation once you get familiar. The presence of a top LCD display reporting shutter speed, aperture, and battery level further improves usability during critical shoots.

Autofocus: Simplicity vs. Precision

Both cameras provide nine autofocus points, but their technology and implementation differ radically:

• Panasonic LS5: Uses contrast detection AF with face detection. It locks focus decently for static subjects but is slow to react in low light or moving subjects. Only single AF mode is available; no continuous tracking or advanced AI.

• Sony A850: Employs phase detection AF with nine focus points, including selective and multi-area AF modes. This system excels in accurate focus acquisition on different zones, ideal for portraits with eye focus or wildlife in motion, albeit without animal eye tracking.

In my practical tests photographing children playing and birds fluttering in the park, the LS5 regularly missed fast action or required focus hunting, resulting in missed frames. Meanwhile, the A850’s DSLR-grade AF locked quickly and precisely, enabling me to keep up with scenes at 3 fps continuous shooting.

Photography Genres Illuminated: When to Choose Each Camera

Portraiture - Skin Tones, Bokeh, and Eye Detection

The Sony A850’s large full-frame sensor, combined with interchangeable Sony Alpha lenses, easily produces creamy bokeh and beautiful skin tones. Full control over aperture and manual focus enhances portrait creativity.

The Panasonic LS5’s limited wide aperture (max f/2.8 at wide) and small sensor restrict depth-of-field control and natural background separation. Its face detection autofocus helps beginners capture decent portraits but lacks sophistication.

Landscapes - Resolution, DR, and Weather Sealing

Being equipped with a robust magnesium alloy body and full weather sealing, the Sony A850 is built for serious landscape photography - even in challenging, inclement conditions. The sensor’s dynamic range captures rich tonal contrasts, crucial when shooting scenes with bright skies and dark shadows.

The Panasonic LS5 lacks any environmental sealing, so shooting in rain or dusty situations requires caution. Its limited dynamic range, lower resolution, and smaller sensor limit image quality for expansive prints or heavy post-processing.

Wildlife Photography - Autofocus Speed, Telephoto Reach, and Burst

The LS5’s 5x zoom lens (equivalent 26-130mm) is relatively short for wildlife and combined with sluggish single AF and 1 fps shoot rate, makes it poorly suited for fast action or distant animals.

In contrast, the Sony A850’s compatibility with a vast array of Sony Alpha telephoto lenses allows long reach (200mm-600mm+) with excellent autofocus performance and a 3 fps burst mode. Though not as fast as modern pro cameras, it remains capable for many wildlife scenarios.

Sports Photography - Tracking, Low Light, and Frame Rate

Sony A850 edges clearly with higher max shutter speeds (1/8000 vs. 1/2000), faster continuous shooting, and versatile exposure modes (including shutter/prio). Low noise at higher ISO aids indoor or evening sports.

LS5’s slow 1 fps burst, limited shutter speed, and fixed aperture mean you risk motion blur and missed moments during dynamic sports action.

Street Photography - Discreteness, Portability, Low Light

Panasonic LS5’s compact size and light weight allow discrete shooting, making it a decent companion for candid street images. The optical image stabilization helps hand-held low-light shots up to ISO 400 before noise becomes an issue.

Sony A850 is heavier and louder, making it less ideal for unobtrusive street work but better for planned walks where image quality is paramount.
