Sony HX100V vs Sony A77 II: Bridging the Gap from Superzoom to Advanced DSLR

Choosing a camera today is like navigating a jungle of buzzwords, specs, and niche categories. Between a compact superzoom bridge camera and a mid-range advanced DSLR, the choice can be daunting - especially when both come from the same respected brand like Sony. Today, I’m digging deep into two such models: the Sony Cyber-shot DSC-HX100V (simply “HX100V”) and the Sony SLT-A77 II (“A77 II”). These two cameras sit on vastly different rungs of the ladder - the HX100V is a versatile, pocket-friendly superzoom introduced in 2011, and the A77 II is a 2014 mid-size DSLR designed with serious enthusiasts and professionals in mind.

I’ve spent weeks testing and comparing these cameras in various scenarios - from portrait studios to wild landscapes - measuring how their technology translates into real-life shooting. Whether you’re an aspiring enthusiast debating your next move, or a professional looking for a solid backup, this detailed comparison aims to clarify the strengths, drawbacks, and use-case sweet spots for each.

Let’s start by putting their physical presence into perspective.

How Big a Deal Is the Difference in Size? Spoiler: Pretty Big

If you’re like me, ergonomics are make-or-break. Handling a camera that fits just right in your hands saves countless moments of frustration and missed shots.

The HX100V is a classic bridge-style camera - designed to mimic an SLR silhouette but with a fixed lens and lighter build. Measuring roughly 122 x 87 x 93 mm and weighing 577 grams, it feels compact enough for travel and walk-around shooting but still substantial enough to give you that confidence-to-shoot grip.

On the other side, the A77 II, at 143 x 104 x 81 mm and 647 grams, embraces the heft and build quality of a mid-size DSLR - larger, yes, but with ergonomics molded for extended handling and a more tactile shooting experience. Its wider grip and more advanced controls are built for those who demand more direct access and customization in the field.

Physically, if pocketability and weight are your top concern, HX100V wins hands down - it slips into a large coat pocket or modest bag, ready for spontaneous shooting. The A77 II requires dedicated carrying space, but rewards with a more robust interface and grip comfort for long sessions.

Now that we have a sense of their form factors, let’s peek at the all-important controls and layout.

Controls and Interface: Direct Shooting vs. Full Control Arsenal

Peering down from above often reveals how a camera’s DNA expresses itself: minimal or packed with buttons?

The HX100V’s top deck is clean, prioritizing simplicity. Key dials and buttons are functional but minimal - a familiar, no-fuss layout that invites fast shooting without a steep learning curve. This is consistent with the bridge camera philosophy: “Point, shoot, zoom, done.”

Contrast this with the A77 II’s top view - it bristles with dedicated dials, a top status LCD, and customizable buttons. The inclusion of shutter priority, aperture priority, manual mode, and more pro-level controls underscore its advanced heritage. The dual-dial system (front and rear) facilitates quick parameter tweaks - a boon for those who want to juggle settings on the fly without diving through menus. The illuminated buttons might be absent, but the array is thoughtfully laid out and positively inviting for photo veterans.

For anyone who likes to feel the interface, the A77 II makes a convincing case - no surprise for a camera designed with enthusiasts and pros in mind. If you prefer straightforward shooting without distractions, HX100V’s simplicity wins.

Speaking of displays - what do these cameras offer for composing and reviewing shots?

Screens and Viewfinders: Clarity Where It Counts

Electronic viewfinders paired with quality LCDs are essential for composing shots in diverse scenarios - from blinding midday sun to dimly lit rooms.

The HX100V boasts a 3-inch, 921k-dot tilting LCD equipped with Sony’s XtraFine TruBlack technology. The tilting feature offers flexibility to shoot at awkward angles, albeit lacking touchscreen capability - common for its era. The electronic viewfinder, though unspecified in resolution, serves as a convenient alternative to the LCD, especially in bright environments.

The A77 II takes this up several notches: a fully articulated 3-inch LCD with 1.23 million dots allows for versatile shooting angles - think low ground or overhead shots. The non-touchscreen interface is manageable once you get accustomed. What really stands out is its electronic viewfinder, boasting 2.35 million dots, 100% coverage, and 0.73x magnification. In practice, this means the A77 II’s EVF offers a rich, bright, and detailed preview far superior to HX100V’s basic EVF. My tests showed this made manual focusing, especially in portrait and macro scenarios, significantly easier and more reliable on the Sony A77 II.

Bottom line? For casual users, the HX100V’s screen and EVF suffice, but professionals craving precision and flexibility would appreciate A77 II’s larger, sharper displays.

Let’s zoom in on the heart of every camera: the sensor.

Sensor Showdown: Tiny Superzoom Sensor vs. APS-C Powerhouse

Here’s where the two diverge most dramatically. The HX100V features a 1/2.3-inch BSI-CMOS sensor - typical for superzoom and compact cameras - measuring 6.17 x 4.55 mm with around 16 megapixels. Small sensors like this can cram lenses into compact bodies and fuel an insane 30x zoom (27-810mm equivalent) but bear the usual trade-offs: limited dynamic range, higher noise at elevated ISO, and less depth-of-field control.

In contrast, the A77 II is built around a robust APS-C CMOS sensor sized 23.5 x 15.6 mm with 24 megapixels - that’s over 13 times the sensor surface area. Coupled with Sony’s Bionz X processor, this camera delivers striking improvements: higher native ISO range (50–25600), wider dynamic range (13.4 EV at base ISO per DxOMark), and significantly better color depth.

In practical terms: portraits shot with A77 II exhibit creamy bokeh and nuanced skin tones thanks to larger sensor size and better optics. Landscapes reveal more details in shadows and highlights, and shots in dim lighting retain usable detail with much less dreaded noise.

The HX100V’s small sensor means you must be mindful of exposure and lighting - shooting in bright daylight yields best results, while shadows and low light tend to get noisy and mushy. However, in daylight landscapes or casual travel photography, it can hold its own thanks to its long zoom.

My shootouts proved this conclusively: even with superior post-processing, the HX100V’s images start showing quality gaps at ISO 800 and above, while the A77 II maintains clarity well beyond ISO 3200.

If image quality tops your list, there’s no contest here - the A77 II’s APS-C sensor is a game-changer. That said, there are scenarios where the HX100V’s zoom range is a decisive advantage, especially when lugging heavy lenses is out of the question.

Now, what about autofocus - often the unsung hero in capturing decisive moments?

Autofocus and Shooting Speed: Catching the Moment with Confidence

Autofocus in the HX100V is a basic contrast-detection system with 9 focus points but no continuous AF or tracking. For quick snaps, especially static subjects, it works fine. However, fast-moving subjects or dynamic environments expose its limits. Also, face detection is absent, which can be frustrating for portraits or group shots.

The A77 II wears its autofocus credentials boldly: 79 phase-detection points (15 cross-type), continuous AF tracking, face detection, selective AF, and live view AF. This beast can shoot at a blistering 12 fps burst speed with full AF tracking - remarkable for a DSLR-class camera.

My hands-on testing in wildlife and sports conditions confirmed the A77 II could lock and follow erratic birds in flight or kids sprinting across fields with impressive accuracy. The HX100V struggled to keep pace - which isn’t a surprise given its consumer-oriented design.

For static subjects, street photography, or casual use, the HX100V’s AF suffices. But for action, wildlife, or sports photography, the A77 II is clearly superior.

Picture’s Worth a Thousand Words: Sample Images Side-by-Side

After walking through specs and impressions, here are some side-by-side sample shots taken with each camera on the same day, under near identical conditions.

• The portrait images from A77 II show beautifully rendered skin textures and smooth bokeh that isolates the subject effortlessly.
• The HX100V portraits look decent under controlled daylight but fall short in low-contrast scenes. Eye detection absence shows up here as struggles to auto-focus crisply.
• Landscape shots reveal the 24MP sensor’s detail advantage and wide dynamic range in the A77 II. Shadows retain finer nuances, and highlights are better preserved.
• The HX100V captures catchy scenes but with noticeably less depth and slight noise creeping in shadows.
• Wildlife shots were fun with A77 II - its quick AF and high fps nailed action sequences that the HX100V couldn’t match.

This gallery tells a clear story of sensor and AF prowess - and by extension, overall image quality.

Outdoor Stamina: Weather Sealing and Battery Life Examined

Outdoor photographers will appreciate the A77 II’s partial environmental sealing, protecting against dust and light moisture - a thoughtful touch in a mid-price DSLR. The HX100V omits sealing altogether, reinforcing its role as a street or casual travel camera not meant for rugged use.

Regarding battery life, the A77 II also shines. It shoots approximately 480 frames on a single charge using the EVF - considerably above average. The HX100V’s battery life isn’t specified precisely, but smaller bridge cameras typically yield fewer shots per charge.

For day-long excursions or demanding shooting days, the A77 II offers peace of mind and durability.

From Pixels to Video: Moving Beyond Stills

Video enthusiasts will find interesting contrasts here too.

The HX100V offers 1080p video at 60fps with MPEG-4 and AVCHD codecs, a respectable offering at its release time. Its optical image stabilization helps smooth handheld footage, though microphone input is absent - limiting external audio options.

The A77 II provides 1080p at multiple frame rates (60p, 60i, 30p) and supports XAVC S codec providing superior compression quality. Critically, it has a microphone input port but lacks headphone out, putting it one step shy of prosumer video rigs but definitely ahead of the HX100V.

Both have HDMI output and standard USB 2.0 connectivity, but the A77 II also sports NFC for swift pairing - a modern convenience.

If you care about video seriously, the A77 II is a better toolkit, but don’t expect 4K or ultra-high-res video on either.

Lenses and Expandability: Fixed Zoom vs. Vast Alpha Ecosystem

A quick reminder: the HX100V sports a hefty fixed 30x zoom lens, 27-810 mm equivalent, with variable aperture from f/2.8 to f/5.6. This flexibility is impressive in a compact form and great for travel or all-in-one gear minimalist setups.

The A77 II, on the other hand, benefits immensely from Sony/Minolta Alpha’s lens legacy with 143 compatible lenses - covering primes, zooms, macros, and specialty optics. That focal length multiplier of 1.5 means APS-C lenses behave accordingly - great for telephoto reach, especially in wildlife and sports.

I can vouch from personal experience: having access to varied lenses transforms this camera from a versatile all-rounder to a specialized powerhouse depending on your shooting goals.

Need macro? There’s a dedicated lens. Want ultra-wide? No problem. Portrait bokeh? Fast primes abound. Fixed lens cameras, no matter how zoomy, simply can’t compete with such flexibility.
