Two Sony Ultracompacts Compared: The Cyber-shot DSC-T90 vs. DSC-W510 - Which One Deserves Your Pocket?

Over my 15+ years of reviewing cameras, I’ve learned that ultracompact cameras, despite their modest size and specs, can still deliver surprisingly good results for casual shooting and travel snapshots. Today, I’m putting under the microscope two affordable, entry-level Sony ultracompacts from different eras: the 2009 Sony Cyber-shot DSC-T90 (hereafter, “T90”) and the slightly later 2011 Sony Cyber-shot DSC-W510 (“W510”). Both appeal to budget-conscious photographers looking for simple point-and-shoot convenience, but the differences quickly become clear once you get beyond the surface.

Having spent hands-on time shooting with both in real conditions and tested their specs carefully, I’ll walk you through a comprehensive comparison - from physical feel and ergonomics through sensor performance, autofocus, and suitability across popular photography types. Along the way, I'll give you candid thoughts on what each camera can and can’t do, and who should seriously consider them.

Let’s dive in.

Size, Feel, and Usability: What’s It Like in Your Hands?

When it comes to ultracompacts, physical handling is often the first - and sometimes last - deal breaker. You want a camera that slips easily into your pocket but still offers enough control to feel comfortable.

Take a look at these two side by side. The Sony T90 is incredibly thin and sleek, measuring just 94 x 57 x 15 mm and weighing 148 g. Its slim profile is great for portability but comes at the cost of grip comfort - there’s barely any room for your fingers to find a natural hold, and the flat “clubs for thumbs” back doesn’t help either.

Contrast this with the W510, which is chunkier at 96 x 54 x 20 mm and lighter at 119 g due to simpler construction materials. The extra thickness actually makes the W510 easier to hold securely, though it also means it won’t quite slide into tight pockets as sleekly as the T90.

In terms of control layout, the T90’s top-mounted buttons are minimal - there’s no dials or customizable controls, but it has a touchscreen interface which, for the era, is a nice bonus. The W510, on the other hand, sticks to physical buttons without touchscreen support, which means it’s simpler but less versatile for menu navigation.

The W510’s buttons feel more tactile and forgiving when shooting on the fly, whereas the T90’s touchscreen sensitivity could sometimes be hit-or-miss, especially with sweaty or gloved fingers.

Winner for ergonomics: W510, for better grip and more dependable controls, despite the T90’s more modern touchscreen.

Sensor and Imaging Core: Not All Pixels Are Created Equal

Both cameras share the same sensor size and resolution on paper - a 1/2.3" CCD sensor with 12 megapixels (4000 x 3000 pixels). This sensor size, roughly 28 mm² area, is common in compact cameras, balancing cost and image quality. Still, some crucial differences lie beneath.

CCD sensors are renowned for good color rendition but can lag in noisy low-light performance compared to CMOS. Both cameras utilize CCDs, but the T90 lacks a dedicated image processor specification, while the W510 boasts Sony’s BIONZ processor. This makes a tangible difference in noise suppression, color processing, and image sharpening.

In practice, the W510 produces cleaner images at higher ISOs and better color consistency, especially in challenging lighting. The T90 tends to introduce more chroma noise past 400 ISO, limiting its usable ISO range to daylight or well-lit situations.

Resolution-wise, both cameras yield similar levels of detail in bright light. That said, the W510’s slightly faster lens aperture (F2.8 at wide) helps gather more light for better exposure and shallow depth of field capabilities - key for portrait bokeh and subject isolation.

In terms of color depth and dynamic range, both models fall into entry-level territory - neither can match modern mirrorless cameras - but the W510’s processing edge makes a credible difference, particularly in handling shadows without crushing them.

LCD Screens and Viewfinding: What You See Is What You Get

Neither model includes an electronic viewfinder (EVF) - a common omission in ultracompacts - so the rear LCD screen is your only framing help.

The T90 sports a 3.0-inch touchscreen with a relatively low resolution (230k dots), while the W510 opts for a smaller 2.7-inch non-touch Clear Photo LCD, also 230k dots.

While the T90’s touchscreen adds convenience for menu navigation and shot confirmation, it can be finicky under certain lighting conditions - bright daylight glare reduces visibility and touch responsiveness suffers if your fingers aren’t dry or steady.

The W510’s screen doesn’t offer touch but maintains solid visibility, especially thanks to the Clear Photo LCD tech, with good color accuracy and brightness. For framing, neither screen is particularly sharp by modern standards, but the W510’s smaller screen actually means you’re slightly less tempted to zoom in or rely on touchscreen fiddling.

For critical focus or compositions, both are handicapped by the lack of EVF; I found myself relying on the LCD more, which can be unwieldy for sunny outdoor shooting or dynamic street photography.

Lens and Zoom Capabilities: Reach and Brightness in Your Pocket

A fixed lens means you’re limited, so the optical zoom and aperture range become king.

• Sony T90: 35–140 mm (35mm equivalent), 4x zoom, aperture F3.5–10.0
• Sony W510: 26–104 mm (35mm equivalent), 4x zoom, aperture F2.8–5.9

The W510 wins the opening round here. Its wider 26 mm starting focal length offers a broader field of view for landscapes and group shots, where the T90’s 35 mm start feels tight.

Plus, the faster maximum aperture on the wide end means better low-light and better background separation when you zoom out; the T90’s lens maxes out at F10 at telephoto, which is quite slow and limits low-light handheld shooting and depth control.

Neither has image stabilization technology omitted: the T90 opts for optical image stabilization while the W510 features sensor-shift stabilization. In practical use, the W510’s sensor-shift seemed slightly more effective at steadying shots, especially in low light or at longer focal lengths.

Regarding macro performance, the W510 can focus down to 4 cm, a nice touch for close-up details, whereas the T90 doesn't specify macro focus and was clunkier in practice for tight close-ups.

Autofocus: Speed, Accuracy, and Focus Points

For ultracompacts, autofocus (AF) systems are usually basic - and both the T90 and W510 stick with contrast-detection AF.

Both cameras feature nine AF points without cross-type sensors, no phase-detection, face detection, or tracking technologies, limiting their speed and accuracy in tricky scenarios.

However, the T90 offers touch autofocus, enabling you to tap the screen to set focus points - a nice bonus when it works - but the W510 sticks to traditional button controls and center-weighted AF.

Neither camera supports continuous AF or subject tracking, so for dynamic subjects like sports or wildlife, don’t expect top-tier performance. Manual focusing isn’t an option on the W510, and it’s clunky on the T90.

In daylight static shots, both lock focus reliably, but slow contrast detection means hunting in low light or fast-changing scenes.

Burst Shooting and Video: Action and Moving Images

Burst capabilities are modest at best:

• The T90 offers continuous shooting at 2 fps, enough for casual captures but not competitive for sports or wildlife.
• The W510 drops to a single frame per second burst, making it less suitable for moving subjects.

On video, the T90 can shoot 720p HD (1280x720) at 30 fps, a strong advantage over the W510, limited to 640x480 VGA resolution at 30 fps. However, neither have microphone inputs or advanced codecs, restricting serious video creation.

Neither camera offers 4K or slow-motion features, nor do they support image stabilization in video mode.

Battery Life and Storage: Practical Considerations

Both cameras accept a single storage card slot:

• T90 uses Sony’s proprietary Memory Stick Duo / Pro Duo
• W510 supports SD/SDHC/SDXC cards plus Memory Stick formats, providing more flexibility and cheaper, widely available storage.

Battery life is not officially rated for either, but in practice, the W510’s NP-BN1 battery lasts longer because of less power-hungry features and smaller LCD screen size. The T90’s reliance on touchscreen and optical stabilization drains juice faster.

Connectivity and Build Quality: Durability vs. Convenience

Neither features wireless functions like Wi-Fi, Bluetooth, or NFC, which is hardly surprising given their release dates and target market.

Only the T90 offers an HDMI port, allowing you to view photos on a TV - a small plus. The W510 only has USB 2.0.

Neither camera boasts any weather sealing or rugged design, so cautious handling is advised - these are everyday carry cameras, not adventure companions.

Real-World Shooting Across Photography Types: Which Excels Where?

Now that the technical basics are out of the way, let’s answer the key question: which camera is better suited for which photography discipline? I’ll summarize based on hands-on experience, shooting dozens of test scenarios for this review.
