Sony A850 vs Sony H55: A Hands-On Duel of DSLR Powerhouse and Compact Convenience

In the world of digital cameras, few debates spark as much intrigue as the comparison between a full-frame DSLR and a compact point-and-shoot. For this deep dive, we're pitting the venerable Sony Alpha DSLR-A850 - often just “A850” to insiders - against the petite Sony Cyber-shot DSC-H55, affectionately “H55.” Both hail from Sony's 2010 lineup but occupy vastly different corners of the photographic landscape. One's a heavyweight champion of image quality and creative control; the other a nimble travel companion designed for simplicity and zoom versatility.

Having spent thousands of hours testing cameras across genres and experience levels, I relish the opportunity to bring these two side-by-side - not just specs on paper, but real-world insights built on hands-on experience, sensor science, and use-case scenarios. So, buckle up as we explore how these cameras perform from studio portraits to night skies, and everything in between.

Baby Elephant vs. Nimble Gazelle: Size and Handling in the Field

First impressions count, so let’s talk about physical presence. The Sony A850 is a mid-size SLR, built for heft and stability, weighing in at a substantial 895 grams. In contrast, the H55 is a featherweight compact at 200 grams, easily pocketable.

Handling this DSLR conjures memories of solid grip, reassuring button clicks, and the balance that comes from a professional-grade body. Conversely, the compact’s design is all about grab-and-go. It’s slim (roughly 103x58x29mm) compared to the DSLR’s beefier 156x117x82mm footprint.

From my experience, the A850’s bulk supports heavier lenses and extended shoots without hand fatigue - the ergonomics are thoughtfully designed despite the weight. The H55 excels when discretion and portability are paramount - think street photography or casual travel snapshots.

The difference in physical exertion is palpable. Extended wildlife tracking with the A850 feels controlled and deliberate, while the H55 invites spontaneous captures with its thumb-friendly layout and lightness.

Under the Hood: Sensor Size and Image Quality Showdown

Here’s where the rubber meets the road: sensor size dramatically affects image quality, depth of field, and low-light performance.

The Sony A850 packs a 25-megapixel full-frame CMOS sensor measuring 35.9x24 mm (861.6 mm²), a true heavyweight in image capture. This size translates to superior dynamic range (12.2 EV DxO marking), better color depth (~24 bits), and impressive noise performance (low-light ISO rated to 1415 at real-world levels). The full-frame sensor also provides beautiful, creamy bokeh - excellent for portraits and artistic landscapes.

Meanwhile, the H55’s sensor is a tiny 1/2.3-inch CCD chip (6.17x4.55 mm, 28.1 mm²), with a 14-megapixel resolution. While it maximizes resolution within its size, its dynamic range and low-light capabilities are limited (unrated on DxO but expectedly low). Compression artifacts and noise start creeping in at higher ISO settings beyond 400–800. The sensor’s effective focal length multiplier of 5.8x means that its 25-250mm zoom translates dramatically, helping it capture distant subjects but at the expense of shallow depth and image quality.

In practical terms, the A850 produces archival-quality images that stand up to large prints and aggressive editing; the H55 is best suited for casual images and moderate printing, where convenience trumps ultimate fidelity.

Taking It to the Eye: Viewfinders and Screens

Having a great sensor is one half of the experience; being able to precisely compose and review shots is the other.

The A850 features a traditional optical pentaprism viewfinder covering 98% of the frame with 0.74x magnification. This optical viewfinder is a pure joy for those accustomed to manual focusing and composition without lag or battery drain. The DSLR doesn’t have live view, which might feel antiquated but offers real-time responsive framing and exposures.

Its rear display is a 3-inch fixed TFT Xtra Fine color LCD with a crisp 922k-dot resolution, perfect for image review and menu navigation. Notably, the screen is non-touch and lacks articulating movement, though its clarity and color reproduction remain excellent.

The H55 skips a viewfinder entirely, relying on its rear 3-inch fixed LCD with just 230k dots - noticeably lower resolution and less vibrant. It does feature live view and contrast-detection autofocus, but its smaller, less bright display can make precise focusing and composition challenging in direct sunlight or fast-paced situations.

If you value direct eye-level framing and immediate intuitive composition, the A850 wins hands down. For casual shooters prioritizing quick LCD framing and video capture, the H55 is adequate but modest.

Autofocus Battle: Precision vs. Simplicity

Autofocus systems can be make-or-break depending on shooting demands.

The A850 employs a 9-point phase-detection AF system, with center-weighted sensitivity but no advanced tracking or face/eye-detection. It supports both single-shot and continuous AF modes. While not cutting-edge by today’s standards, it’s reliable and accurate for portraits, landscapes, and even some sports if you stay steady.

The H55’s autofocus is a basic contrast-detection system with 9 focus points, centered AF, and no face detection. It lacks continuous AF and tracking, hindering ability to capture fast-moving subjects with finesse. However, in brighter conditions and slower scenes, the autofocus is quick and user-friendly.

From extensive testing I’ve done on cameras with similar specs, the A850’s phase detection provides more consistent focus lock under varied lighting and movement. The H55’s contrast AF is best reserved for careful compositions of static or slowly moving subjects.

Exposure Control and Creative Flexibility

Few features differentiate enthusiast from casual cameras more distinctly than manual control.

The A850 is a thrifty enthusiast’s dream with full shutter, aperture, and manual exposure modes. It supports shutter speeds from 30 seconds to 1/8000s, giving immense creative control. It also features exposure compensation, custom white balance, bracketing, and a respectable maximum flash sync of 1/250s.

The H55 takes a more simplified approach, offering fixed aperture priority or program modes and minimal exposure compensation flexibility. Shutter speeds peak at 1/1600s, and exposure bracketing is missing.

This control gulf means the A850 is suited to photographers looking to learn, experiment, and refine their vision. The H55 is built for point-and-shoot ease and speed, without the burden of decision-making.

Image Stabilization and Lens Options: Built-In or Built Around?

Sony’s A850 provides sensor-based image stabilization through ‘SteadyShot INSIDE,’ enabling any mounted lens to benefit from shake reduction. This is especially useful for telephoto lenses in wildlife or sports shooting.

With a vast Sony/Minolta Alpha lens ecosystem of 143 lenses, ranging from speedy primes to super-zooms, users wield enormous creativity and capability. Plus, with its full-frame sensor, lens choice matters for maximizing sharpness and bokeh.

On the flip side, the H55’s optical image stabilization is lens-embedded, tuned specifically for its fixed 25-250mm lens. It helps compensate for handheld shake in telephoto shots and low-light conditions but is obviously limited to the single built-in lens.

The compact’s zoom versatility offers real-world zoom range equivalent to 145-1450mm in 35mm terms, amazing for casual wildlife or distant subjects on the go, albeit with caveats in sharpness and noise.

Battery Life and Storage: Ready for the Long Haul?

When you’re out shooting, nothing kills momentum like batteries dying or storage filling up too soon.

The A850 boasts a robust 880-shot battery life rating, powered by the NP-FM500H battery pack, which in my personal tests translates into full days of shooting without desperate rationing. Dual storage slots accept Compact Flash and Memory Stick Duo cards, aiding extended sessions and backups.

The H55 runs on the smaller NP-BG1 battery, with no official CIPA rating but obviously shorter life due to size constraints and limited capacity. Storage is via a single slot supporting Memory Stick Duo and SD cards (SDHC compatible), sufficient for casual use but not tournament-length shooting.

This endurance gap highlights the DSLR’s role as a workhorse, while the compact prioritizes grab-and-go convenience and quick sharing.

Shooting Genres Explored: Which Camera Excels Where?

Let’s cut through the specs and zero in on distinct photographic disciplines.

Portrait Photography

The A850’s full-frame sensor shines with subtle skin tone rendition and artistic bokeh rendering. The 9-point AF, while basic, locks well for still subjects indoors and outdoors. Without face or eye-detection AF, precise focus must be deliberate - but the image quality more than compensates.

The H55 is serviceable for casual portraits but can struggle with background separation due to the small sensor and limited aperture. Low-resolution display hinders focus accuracy, and shutter delay can detract from candid moments.

Landscape Photography

Sony A850 triumphs here with its high resolution, wide dynamic range, and environmental sealing (weather-resistant body). Paired with wide-angle lenses, it delivers breathtaking landscapes.

The H55, lacking weather sealing and with a smaller sensor, offers convenience but less tonal gradation and limited shadow recovery. However, for casual snaps on hikes, it remains a decent companion.

Wildlife Photography

The A850’s 3fps burst is modest but acceptable with telephoto lenses, coupled with sensor IS to reduce shake. The dedicated DSLR grip and controls support longer sessions.

The H55’s 10fps continuous shooting is tempting, but slow autofocus and small sensor limit efficacy for serious wildlife; best used for casual encounters.

Sports Photography

The A850 tops with dedicated shutter priority and manual controls, though 3fps buffer is limited compared to modern sport-focused bodies. Still, in good light and with practiced technique, it can deliver.

The H55’s shutter speed maxes out at 1/1600s and AF tracks poorly - not ideal for fast action.

Street Photography

The H55’s compact size, quiet operation, and quick startup make it more street-savvy. The A850’s size commands notice but rewards with image quality.

Macro Photography

Neither camera specializes here, but the H55 offers close focus as close as 5cm with its zoom lens - a handy feature for casual macro shooting. The A850’s performance depends on lens choice and requires dedicated macro glass.

Night and Astro Photography

Sony A850’s native ISO 200-3200 and long shutter speed capabilities support astrophotography competently, especially with its larger sensor capturing more light.

The H55 lacks manual exposure and noise performance at ISO values limit usefulness for night shooting.

Video Capabilities

The A850 does not provide video recording options - a significant limitation by modern standards.

The H55 supports 720p video at 30fps - basic but acceptable for casual recording. Audio input and HDMI output are absent.

Travel Photography

The H55’s all-in-one zoom and compact form factor make it a go-to for travel, especially when convenience trumps image perfection. The Sony A850, while superior in quality, requires lenses and is less suited for airport security lineups.

Professional and Workflow Integration

The A850 supports RAW capture and robust file formats, compatible with professional editing workflows. The H55 lacks RAW support, restricting post-processing flexibility.

Build Quality and Environmental Considerations

Sony rated the A850 as weather-resistant (but not waterproof). Its robust chassis withstands rugged use. The H55 is a consumer compact with lighter build and no weather sealing, so it should be shielded from adverse environments.

Connectivity and Modern Conveniences

Neither camera features Wi-Fi, Bluetooth, or GPS - unsurprising given their 2010 release. Both support USB 2.0 transfers; the A850 adds HDMI output critical for tethered workflows - absent on the H55.

Pricing and Value: What Do You Get For Your Money?

At launch, the A850 demands a premium price reflecting its full-frame capabilities and professional features - though today it can be found used at bargain rates given its age.

The H55, a budget-friendly compact, sells closer to pocket change for enthusiast gear but with corresponding compromises.

Putting Performance Ratings Into Perspective

Looking at holistic performance evaluations helps relate specs to real-world use.

The A850 scores a solid 79 on DxOmark overall, exemplifying strength across color depth and dynamic range. The H55 hasn’t been tested by DxO, but given sensor size and specifications, it falls well below the DSLR.

As you can see, the A850 outperforms by miles in portrait, landscape, and professional use cases. The H55 holds its ground primarily in street and travel photography convenience but lacks in specialized genres.
