Sony HX90V vs Sony A58: A Hands-On Comparison for the Photography Enthusiast

Choosing between a compact superzoom and an entry-level DSLR can be surprisingly tricky, especially when both come from a respected name like Sony and offer distinct advantages. Today, I'm diving deep into two intriguing models: the Sony Cyber-shot HX90V, a small sensor superzoom camera released in 2015, and the Sony A58, an entry-level DSLR announced back in 2013.

I’ve put both cameras through their paces, testing them across a wide range of photographic disciplines and real-world scenarios. This comparison isn’t just about specs on paper. I’ll share insights from my own extensive experience, scrutinize image quality, autofocus, ergonomics, and more - equipping you to pick the right tool for your creative style and budget.

Let’s start by getting to know their fundamental differences.

Size, Build, and Ergonomics: Compact Convenience vs DSLR Presence

At first glance, these cameras could hardly be more different physically. The HX90V is a pocket-sized marvel, designed to fit discreetly into a coat pocket or small bag. Sony kept it compact at 102 x 58 x 36 mm and a featherlight 245 grams - perfect for travel and street photographers who prize portability.

On the other hand, the A58 embraces its DSLR heritage with a more substantial, robust body measuring 129 x 95 x 78 mm and weighing in at 492 grams. This heft translates into a firmer grip and more physical control, which I found especially welcome during long shoots where steadiness matters.

The DSLR shape also allows space for an array of buttons and dials, which the smaller HX90V cannot fully accommodate. More on that in a moment. If you want to blend into a crowd or travel light, the HX90V wins hands down. But if you prefer the feel, presence, and manual control of a traditional camera, the A58 is your go-to.

Ergonomics continue on the top plates - the HX90V sports modest physical controls with a mode dial, zoom lever integrated into the shutter button, and a simple power switch. It’s well laid out but necessarily minimalistic, reflecting the camera’s all-in-one nature. I appreciated the convenience, but if you’re a fan of tactile control, sometimes a touchscreen or additional buttons are missed.

The A58’s DSLR heritage is evident in its more complex control scheme - dedicated dials for exposure compensation, modes, and an ISO button that can be repositioned to taste. During extended shoots, I preferred the instant access to these settings, allowing me to tweak without digging into menus. The 15 autofocus points with 3 cross-type sensors also mean more precise manual or semi-automatic focus adjustments, which you won’t find on the simpler HX90V.

If you’re comfortable with menus and prefer simplicity, HX90V’s control scheme makes life easy. For shooters craving more physical input options and faster in-the-moment control, the A58 edges ahead.

Sensor Size and Image Quality: The Heart of the Matter

Here’s where we get to the meat of the difference. The HX90V is built around a 1/2.3-inch sensor measuring 6.17 x 4.55 mm, delivering 18 megapixels. This sensor is a back-illuminated CMOS type, excellent for a compact camera, but small compared to the APS-C sized 23.2 x 15.4 mm CMOS sensor in the A58, which boasts 20 megapixels.

Why does sensor size matter? Larger sensors capture more light, resulting in images with better dynamic range, improved low light performance, and less noise. Testing both cameras, I found the A58’s sensor produces noticeably cleaner images when shooting at higher ISO - critical for indoor photography, night scenes, or sports venues with less lighting.

Moreover, the A58 captures slightly higher resolution images at 5456 x 3632 pixels, versus the HX90V’s 4896 x 3672 pixels, allowing more generous cropping or large prints without loss of detail.

If ultimate image quality is your priority and you’re shooting anything beyond daylight conditions, APS-C digital SLRs like the A58 remain first choice. The HX90V performs admirably in good light but hits its limits faster due to the smaller sensor.

Shooting Experience: Viewfinders and Screens

Both cameras feature tilting LCD screens, but the HX90V’s 3-inch, 921K-dot display is larger and higher resolution compared to the A58’s 2.7-inch, 460K-dot screen. For composing and reviewing shots on the go, the HX90V offers more clarity and real estate.

The HX90V also adds a pop-up electronic viewfinder (EVF) with 638K-dot resolution, good for bright outdoor shooting. The A58 sports a higher resolution EVF at 1.44M dots and a 0.65x magnification that provides an immersive view, closer to an optical viewfinder experience, though still electronic in this model.

I personally preferred using the A58’s viewfinder for critical focusing and composing in bright sunlight, where LCDs can struggle. Still, the HX90V’s tilting screen wins for versatile angles and selfie-friendly framing.

Autofocus Performance and Speed: Capturing the Moment

When testing autofocus, I subjected both cameras to real-world movement scenarios - from walking portraits to quick wildlife and sports action.

The HX90V relies on contrast-detection autofocus with face detection and tracking features. It focuses reasonably fast in good light, especially for a compact, and the 10fps burst rate helped capture fleeting expressions. However, in lower light or fast-moving situations, the AF occasionally hunts and lags, exposing the limitations of a contrast AF system.

Conversely, the A58 uses a 15-point phase-detection AF system integrated into its translucent mirror design. This continuous AF allows for smoother tracking of moving subjects with minimal lag. While its 8fps burst rate is slightly lower than the HX90V, the improved focus accuracy made images consistently sharper for wildlife and sports scenarios.

For wildlife or fast sports photography enthusiasts, I recommend the A58 for its superior AF tracking and reliability under pressure. For casual use or travel snaps, the HX90V offers a simple system that usually does the job.

Lens Systems and Zoom Flexibility: Fixed vs Interchangeable

The HX90V comes with a built-in fixed zoom lens covering an impressive 24-720mm equivalent focal range (30x optical zoom) - a versatile superzoom package perfect for everything from wide landscapes to distant wildlife. The trade-off is a variable max aperture of f/3.5-6.4, which can struggle in low light at the telephoto end.

The A58, as an interchangeable lens DSLR, supports Sony’s extensive Alpha / Minolta Alpha mount lens lineup - currently over 140 lenses including primes, zooms, macros, and legacy optics. This openness means the A58 can grow with you, offering faster apertures, superior optics, and specialized lenses for every genre.

If you want lightweight all-in-one convenience and a massive zoom range without swapping lenses, the HX90V delivers. But if flexibility, maximum image control, and the option to upgrade glass matter most, the A58 with its wide lens ecosystem is the more future-proof option.

Performance Across Photography Genres: What Each Camera Is Best At

Here’s where personal use really comes into focus. Tests show:

• Portraits: The larger APS-C sensor of the A58 renders superior skin tones with pleasing background blur when paired with fast lenses - a decisive edge. The HX90V has face detection and decent bokeh but can’t match DSLR background separation.

• Landscape: Dynamic range and resolution favor the A58, especially with interchangeable wide-angle lenses. HX90V can manage wide scenes but with less detail and tonal depth.

• Wildlife: The HX90V’s 30x zoom is handy for distant subjects, but slower AF hampers action shots. A58’s faster AF and telephoto lenses make it better for capturing motion.

• Sports: For fast action, the A58’s phase detection AF and quieter burst deliver more keepers. HX90V is less reliable for fast paced subjects.

• Street: HX90V’s compactness and silent operation make it the stealthier choice for candid shots. A58’s size and noise can draw attention.

• Macro: The A58’s interchangeable lenses allow dedicated macro glass and better focusing precision. HX90V’s fixed lens macro mode with 5cm minimum focus offers reasonable closeups.

• Night/Astro: The A58’s cleaner high-ISO capabilities and longer exposures help capture starry skies. HX90V struggles with noise and lacks true manual bulb modes.

• Video: Both shoot 1080p HD, but the A58 includes a microphone input, aiding improved audio. The HX90V benefits from optical stabilization and gentle zoom control but lacks audio inputs.

• Travel: The HX90V’s size, GPS, and WiFi + NFC shine for travel convenience. A58’s bulkier form and shorter battery life require more planning.

• Professional Work: The A58 supports RAW and integrates easily into professional workflows; the HX90V is limited to JPEG, a drawback for serious editing.

Battery Life, Storage, and Connectivity: Practical Everyday Considerations

The A58’s battery excels with a rated 690 shots per charge compared to the HX90V’s 360 shots, a difference you’ll notice on longer outings where changing batteries is inconvenient.

Both cameras support SD cards; the A58 accommodates additional proprietary Memory Stick formats. Connectivity differs: the HX90V comes with built-in GPS and WiFi + NFC for instant sharing, while the A58 lacks GPS but offers Eye-Fi SD card compatibility for wireless transfer. Neither supports Bluetooth.

For photographers who want instant location tagging and easy social uploads, HX90V wins a small convenience battle. In contrast, if enduring battery life is crucial, or you prefer proven DSLR connectivity options, A58 pulls ahead.

Price vs Performance: Where Does Value Lie?

At MSRP, the HX90V retails around $440, the A58 closer to $640. You get significant sensor and lens flexibility improvements with the A58 but pay a premium and sacrifice pocketability.

If you primarily shoot casual subjects, want an all-in-one solution, and value travel readiness, the HX90V offers excellent bang for your buck. Its compromises are reasonable given the size and zoom range.

However, if image quality, manual control, and upgrade potential are your priorities - especially for portraits, landscapes, or demanding low-light environments - the A58 justifies its higher price with better core capabilities.

Sample Images: Seeing Is Believing

In side-by-side tests, images from the A58 show richer tones, sharper detail, and better noise control, especially at ISO 800 and above. The HX90V images appear softer and noisier under the same conditions but remain impressive for a point-and-shoot compact.

The superzoom’s 720mm equivalent reach allows framing a distant subject in tight detail that the A58 would require a telephoto lens to match. So, depending on your priorities, these differences matter differently.

Final Thoughts: Which Sony Fits You Best?

Here’s how I’d sum it up based on extensive hands-on time:

• Choose the Sony HX90V if:
  You want a truly pocketable camera that delivers a huge zoom range, rich feature set with GPS/WiFi, and solid video for casual to enthusiast use. It excels as a lightweight travel companion or street camera where discretion and instant sharing matter.

• Choose the Sony A58 if:
  You want the advantages of a DSLR: superior image quality from a large APS-C sensor, interchangeable lenses, more responsive autofocus, longer battery life, and RAW file support. This camera suits enthusiasts or beginners who want to learn manual controls and aim for higher quality portraits, landscapes, wildlife, and sports.

Both cameras hold up well in their categories, just serve different photographic philosophies. For my money, if image quality and creative control are paramount - and you don’t mind a larger body - the A58 remains an intelligent purchase even years on. But if convenience, extreme zoom reach, and wireless features top your list, the HX90V deserves serious consideration.
