Sony A550 vs Sony H90: An Expert’s Take on Two Generations, Two Worlds

When you first glance at the Sony Alpha DSLR-A550 and the Sony Cyber-shot DSC-H90, you might dismiss them as apples vs. oranges - a DSLR from 2009 pitted against a compact superzoom from 2012. But that’s exactly why this comparison is so intriguing. I’ve spent countless hours testing both cameras across an array of photographic scenarios, and today I’m pulling back the curtain on what makes each tick - and which one deserves a spot in your gear bag, depending on your photography itch (and budget).

Let’s unpack these cameras in detail, exploring everything from sensor technology to ergonomics, performance subtleties to practical usability. Buckle up - it’s going to be a thorough, insightful ride.

Quick Preview: Setting Expectations Straight

Before diving deep, it’s important to recognize the fundamental design goals here. The Sony A550 is an entry-level DSLR aimed at budding enthusiasts craving manual control and better image quality in an affordable package. Meanwhile, the Sony H90 is a bridge-style superzoom compact designed for folks who want everything in one lightweight, pocketable body with an enormous zoom range.

Knowing this, the question is not really “which one is better overall?” but rather “which camera is better suited for your photographic aspirations?”

Size and Handling: DSLR Stature vs. Pocket-Sized Convenience

First impressions matter, and size often equals comfort (or inconvenience) in the long term.

The A550 sports the heft and grip of a classic DSLR - 632 grams and dimensions of 137x104x84mm - substantial but manageable, especially paired with standard DSLRs lenses. Its robust body is designed for extended handheld shooting, with dedicated buttons and a mode dial that feels reassuringly solid.

In contrast, the H90 is a compact marvel at just 222 grams and 105x60x34mm. It’s the kind of camera you can slip into a jacket pocket or small purse without feeling burdened - and though small, it’s thoughtfully laid out for one-handed operation.

Handling-wise, if you relish tactile dials and a commanding grip, the A550 wins hands down. The H90, while user-friendly, can feel fiddly with smaller buttons during fast shooting moments.

Top Layout & Controls: DSLR Complexity vs Compact Simplicity

Looking from above, the A550 reveals its ambitious ambitions: dedicated exposure mode dials, on/off ring around the shutter button, exposure compensation controls, and a hot shoe for flash expansion. This camera invites exploration and manual intervention - a playground for photographers wanting to tweak shutter speeds, apertures, ISOs, or flash settings on the fly.

The H90, stripped down, offers a simple on/off button, zoom toggle, and a mode dial packed with scene modes and basic manual options. It’s perfect for quick snaps or casual shooting but lacks the flexibility desired by creative amateurs striving for precision.

In my testing experience, having the ability to switch to manual shutter priority or aperture priority modes on the A550 was invaluable for controlling depth of field or freezing motion - the H90 invites you to trust the camera’s decision-making more, which can occasionally frustrate experienced users.

The Heart of the Matter: Sensor Size and Image Quality

Here’s where the rubber meets the road - or rather, where photos either shine or fall flat.

The A550 boasts a 14MP APS-C sized CMOS sensor measuring 23.4x15.6mm, which met the high standards of its era. This sensor size means bigger photosites (light-catching pixels), better dynamic range, and superior low-light performance compared to smaller sensor cameras.

Conversely, the H90 uses a tiny 1/2.3" CCD sensor at 6.17x4.55mm, a significant step down in surface area - roughly 13x smaller than the A550’s sensor. Its resolution is slightly higher at 16MP but the small sensor size restricts performance in noise handling and depth of field control.

As for image quality metrics, DxO Mark scores back this up: the A550 earns a solid overall 66, capturing rich color depth (~22 bits), excellent dynamic range (11.8 EV), and impressive low-light ISO capabilities (~800 ISO usability). The H90, unfortunately, was never formally tested by DxO Mark, but consistent CCD sensor shortcomings predictably translate into noisier images at moderate ISOs and lower dynamic range.

This is especially salient in challenging lighting - shadow detail on the A550 retains subtle nuance, while the H90 tends to clip highlights and exhibit noise shadows at anything beyond base sensitivity. For landscape, portrait, or night photography, this distinction makes a qualitative world of difference.

Rear Screens and Viewfinding: Navigating Composition

The A550 features a tilting 3” LCD with 922k-dot resolution - sharp, bright, and versatile for awkward angle shots. The tilting mechanism is a boon for macro or low-angle work where eye-level viewfinders become ineffective.

The H90 offers a fixed 3” screen with 461k-dot resolution using ClearPhoto TFT. Adequate for framing but less vivid and with no articulation, which hampers flexibility.

Notably, the A550 includes an optical pentamirror viewfinder, essential for DSLR purists who prefer eye-level shooting without glare or delay. It covers 95% of the frame with 0.53x magnification, typical for entry cameras but workable.

The H90 lacks any viewfinder, relying entirely on its LCD - fine for bright daylight but tricky in direct sunlight.

For street or travel photographers who prefer shooting discreetly via an eye-level finder, the A550 offers the immersive experience many swear by.

Autofocus Systems: Speed, Accuracy, and Tracking

With autofocus tech evolving rapidly, a look at how these cameras acquire and maintain focus reveals another key difference.

The A550 employs a 9-point autofocus system with phase-detection - known for speed and reliability - plus live view contrast detection. It supports face detection but unfortunately no eye or animal eye AF (which didn’t exist yet). Continuous AF and 7fps burst rates make it relatively responsive for action shots, provided the subject is well lit and contrasty.

The H90 relies on contrast-detection AF (slower and less precise), with a rather basic center-weighted focus area. Face detection is available but no continuous AF for moving subjects and a glacial 1fps max burst. This makes tracking fast-moving subjects effectively impossible.

For wildlife or sports photographers, the A550’s phase-detection and burst rate give it a real edge - I successfully captured birds in flight and children at play with sharp focus and minimal motion blur. The H90, by contrast, is better suited to static subjects or casual scenes where reaction times are more forgiving.

Lens Ecosystems: Flexibility vs. Fixed Convenience

One of the largest decision points - interchangeable lenses or one-size-fits-all?

The A550 uses the Sony/Minolta Alpha mount, compatible with a vast lineup including Sony’s own Alpha lenses and legacy Minolta glass. With over 143 lenses available, ranging from nifty 50mm primes to super-telephoto zooms, this camera provides exciting room to grow, allowing you to tailor your kit for portraits, macro, telephoto wildlife, or landscapes.

The H90 sports a fixed 24-384mm f/3.3-5.9 lens (16x zoom!), covering wide to super-tele zoom. While the sheer versatility is hard to beat, at the cost of optical compromises characteristic of superzooms - softness at telephoto ends, slower apertures restricting low-light capability, and modest bokeh.

No interchangeable lenses mean no swapping to faster primes or specialized optics, limiting creative control and ultimate image quality.

If you cherish lens variety and optical excellence, the A550’s mount flexibility is unrivaled here.

Shooting Experience: Burst, Shutter Speed, and ISO Ranges

The A550 boasts a max shutter speed of 1/4000s and an ISO ranging 200-12,800 native - enabling sharp freeze-frame shots in bright light or high-speed subjects, and reasonable low-light flexibility (thanks to the CMOS sensor’s noise control).

The H90 maxes out at 1/1600s shutter speed and an ISO ceiling of 3200 (though noise becomes significant well before this). Its slower maximum shutter speed limits freezing extremely fast motion, while high ISO performance trails far behind.

Continuous shooting rates (burst speeds) are also telling: 7fps on the A550 versus an anemic 1fps on the H90. For sports, wildlife, or kids at play, the A550 is clearly the better tool.

Portraiture: Skin Tones and Bokeh Mastery

When I put both cameras through portrait shoots, the A550’s larger sensor and interchangeable lenses brought far more flattering skin tone rendition and pleasing background separation.

The inherent shallow depth of field achievable with the Alpha prime or zoom lenses creates nicely blurred backgrounds (bokeh), directing attention precisely where you want it - the eyes.

Face detection autofocus on the A550 worked reliably; eyes were sharp in most cases though without eye-detection AF, pinpoint focus requires some practice.

The H90, with its small sensor and fixed lens, produces generally flatter images with more in-focus background due to deep depth of field, less creamy bokeh, and struggles to render subtle skin tone gradations smoothly.

If portraits are your passion, the A550 remains the stronger performer and more rewarding to shoot creatively.

Landscape and Travel: Dynamic Range and Portability

Dynamic range determines how well a sensor can capture detail in bright skies and dark shadows simultaneously. The A550’s sensor shines here, with an 11.8 EV dynamic range enabling landscape shots with crisp details and balanced exposure, which came through repeatedly in sunrise and sunset scenes.

The H90’s smaller sensor compresses dynamic range - harsh highlights and lost shadow detail become common if not careful with exposure.

On travel, the H90 shines for its svelte size and 16x zoom - fantastic for capturing distant landmarks, street scenes, and variety without weighing down your pack.

The A550, while bulkier, rewards you with higher image quality and creative control when you can manage the load, plus better battery life (480 vs. 290 shots per charge).

Wildlife and Sports: Tracking and Burst Speed

Thanks to phase-detection autofocus and a rapid 7fps burst rate, the A550 is surprisingly spry for an entry DSLR at its price point. Tracking animals or athletes is easier, and image sharpness on moving subjects is often excellent.

The H90’s slower autofocus and 1fps burst speed make it cumbersome for action: missed moments and out-of-focus frames are common unless your subjects stay still.

For wildlife or sports enthusiasts on tight budgets, the A550 is the clear choice.

Street Photography: Low Light Discretion and Portability

Street photography often demands low profile, quick reaction times, and good performance in dim streetlights.

The H90 scores here for sheer discretion - compact, quiet, and fast to deploy. The absence of an optical viewfinder might feel odd to purists, but the camera is nimble.

The A550’s size makes it less discreet - any street photographer will tell you you can catch more candid moments with a small compact. However, the A550’s better high ISO performance helps capture scenes in lower light without resorting to flash.

If you prioritize stealth, the H90 wins. If image quality and control matter more, then A550 is better but less subtle.

Macro Capability: Precision and Magnification

Neither camera is a macro specialist, but their approaches differ.

The H90 allows macro focusing from about 5cm with its fixed lens - convenient for casual close-ups of flowers or small objects.

The A550 relies on compatible macro lenses (or extension tubes) to achieve true high-quality close ups with excellent focusing precision.

In-field, I found the H90’s macro mode quick and fun for spontaneous snaps, but the A550 with a macro prime delivered razor-sharp images with finer detail rendition - ideal for dedicated macro enthusiasts.

Night and Astro: Low Noise and Exposure Flexibility

Night shooting is typically where DSLR sensors show their strength.

The A550’s low light ISO rating (~800 usable) combined with manual exposure modes (bulb shooting possible) make it a better candidate for night and astro-photography.

The H90’s high noise levels at ISO above 400 and limited shutter speed max (1/1600s, no extended exposures) restricts possibilities.

I personally captured more usable night shots and milky way captures on the A550, with cleaner images after noise reduction.

Video: Basic vs. Modest HD

Neither camera is a video stalwart, but the H90 offers modest HD video (720p at 30fps) in MPEG-4 format, while the A550 offers no video capabilities.

Audio input is not supported on either, so videographers must mind sound quality.

Casual video shooters may appreciate the H90’s video feature, but serious video requires modern cameras.

Build Quality and Environmental Resistance

Both cameras avoid rugged weather sealing - so layered protection is advisable for fieldwork.

The A550’s DSLR build is more robust and shock resistant in practice, with metal mounts and solid construction.

Connectivity and Storage

Both cameras rely on single SD or Memory Stick slots and USB 2.0 ports. No wireless or Bluetooth features here - nothing surprising for their respective vintages.

Battery life also favors the A550 (480 shots vs 290), thanks in part to the DSLR design optimizing power consumption.

Summing Up with Performance Scores

While precise numbers only tell part of the story, the A550 consistently outperforms the H90 in core photographic metrics - sensor performance, autofocus speed, burst shooting, ISO versatility - combined with the flexibility of interchangeable lenses and manual controls.

How They Rank in Different Photography Genres

In portrait, landscape, wildlife, and sports, the A550’s capabilities dominate. The H90 holds its own mainly in travel (size + zoom), street (portability), and casual snapshots.

Real-World Sample Images: Seeing is Believing

My Take - Experience and Expertise Weigh In

Having spent hundreds of hours with both cameras across genres, I can attest the A550 still holds merit as a beginner DSLR in a modern secondhand market context, especially for those eager to learn and grow their photography craft. It rewards patience, manual exploration, and creative lens swaps.

The H90 represents the older breed of powerful compacts pre-smartphone photography dominance - still a fun device for quick, casual photography but not ideal for those craving professional control or image quality.

If you’re starting now, my advice is lean towards the DSLR route, unless portability absolutely trumps everything else.

Parting Shots - The Beauty of Choice

Few camera comparisons are purely about “better” or “worse.” Often, it’s which tool aligns best with your photographic journey, style, and patience for mastering craft.

So inspect your priorities carelessly - and choose the one that excites you to shoot more. Because at the end of the day, the best camera is the one you’ll actually pick up and use.

Happy shooting!

If you want to explore modern-day alternatives to either, I’m happy to talk about mirrorless options that might now eclipse these older models in every respect. But for now, the Sony A550 and H90 offer an insightful look at where camera tech stood just a decade ago - and what priorities shaped the user experience.
