Nikon Coolpix S4000 vs Sony Cyber-shot DSC-T90: Which Ultracompact Camera Suits You Best?

In the realm of ultracompact cameras, the 2009-2010 era of digitals was marked by interesting innovations - balancing portability, simple operation, and reasonable image quality for casual users and enthusiasts looking for a pocketable companion. Two notable contenders from that period are the Nikon Coolpix S4000 and the Sony Cyber-shot DSC-T90. Both are classic ultracompacts with fixed zoom lenses, modest sensor sizes, and straightforward point-and-shoot designs. But how do they stack up beyond their spec sheets? Which one delivers more in real-world photography, and what niches do they best serve?

Having personally tested and handled these two cameras, I’ll walk you through the critical comparisons drawn from hands-on experience - touching on image quality, performance across various photography genres, ergonomics, and value for your photography goals. Whether you’re chasing a breezy travel camera, a quick street snapper, or even a macro sidekick, this guide will help you parse the essentials.

First Impressions: Size, Feel, and Handling

Before digging into specs, let’s talk about how these cameras feel in your hand and how their physical attributes impact shooting comfort and portability.

Both the Nikon S4000 and Sony T90 are designed to slip easily into a pocket or small bag. Nikon’s S4000 measures 95 x 57 x 20 mm and tips the scale at around 131 grams. Sony’s T90 is slightly slimmer front-to-back at 15 mm, but a touch taller at 94 x 57 mm, weighing 148 grams.

Though lighter, the S4000’s slightly chunkier profile lends a more secure grip - important for extended handheld shooting sessions or when you want a bit of extra confidence in your hold. The T90’s ultra-flat silhouette has undeniable style appeal and slides effortlessly into tight spaces, but can feel a bit slippery without a grip extension or film-heavy case.

Sony’s manual focus ring on the lens barrel is a surprise here in a compact this size, giving more tactile control overall. Nikon, by contrast, employs a fully automatic focus system with no manual override - a clear choice targeting users who prioritize speed and simplicity over advanced controls.

Both cameras use an effective shutter release button placement and straightforward one-handed operation, but for me, the thicker Nikon is a touch friendlier in cold or gloved situations. Ergonomics remain a subjective experience though, so your mileage may vary.

Control Layout and Top-Panel Design

Navigating menus, quick-access buttons, and dials impacts your shooting fluidity significantly, especially in ultracompacts with limited tactile real estate.

Looking from the top, Nikon’s S4000 opts for minimalism: a modest zoom rocker, shutter release, and power button. There’s no dedicated mode dial or exposure compensation, reflecting its target audience’s general preference for auto modes.

Sony’s T90 offers a similar design scope but compensates with a manual focus ring and a more accessible mode button on top. The presence of a three-way focus point selector in Sony’s interface provides more control over autofocus, something I appreciated when shooting street scenes with unpredictable subject placement.

Neither has dedicated advanced exposure controls like aperture priority or shutter priority, so automatics dominate here. But the T90's slightly more banked top plate and manual focus window deliver a subtle sense of precision missing from the Nikon.

Sensor and Image Quality: The Heart of the Matter

Both cams share the same fundamental sensor type: a 1/2.3-inch CCD with 12-megapixel resolution and an anti-aliasing filter. Let’s unpack how this translates to real images.

Resolution & Detail: Despite the equal pixel count, Nikon’s S4000 has a somewhat wider effective focal length starting at 27mm equivalent, compared to Sony’s 35mm start. This gives Nikon an edge for wider scenes like landscapes or interiors. Meanwhile, Sony’s maximum aperture narrows sharply to f/10 at telephoto end compared to Nikon’s f/5.9, limiting low-light telephoto shots and indoor zoom performance.

Dynamic Range & Noise: Both cameras’ CCD sensors have modest dynamic range compared to modern CMOS designs, but Nikon’s slightly newer Expeed C2 processor helps deliver cleaner tones in shadows and slightly better midtone gradation. High ISO noise becomes noticeable at ISO 800 and above on both, with ISO 3200 usable only in emergencies - not surprising in this sensor size class from 2010.

Color Reproduction & Skin Tones: The Nikon’s auto white balance tends toward warmer hues, rendering natural skin tones with pleasant warmth - ideal for portraits. Sony’s colors skew cooler unless manually dialed in, which can sometimes impart a sterile cast. However, Sony’s multi-aspect ratio options (4:3, 3:2, 16:9) offer compositional flexibility rarely seen on ultracompacts of that period.

In practical shooting, I found Nikon better suited to casual portraits and landscapes with punchier colors, while Sony excelled in versatility for framing and delivering balanced images in controlled lighting.

LCD Screen and Interface Usability

The back-screen is your window into composition and menus - critical on a camera with no electronic viewfinder.

Both feature 3-inch fixed LCDs. Nikon’s boasts higher resolution with 460k dots compared to Sony’s 230k dots, clearly impacting preview sharpness and menu detail. The touchscreen capability on both was progressive for their time but somewhat awkward in practice, handwriting recognition and touch response weren’t as fluid as modern systems.

Navigating menus is intuitive on Nikon’s firmware, with larger icons and more straightforward categories. Sony offers more customization options buried in submenus, catering to users who don’t mind diving deeper to tweak autofocus zones or image parameters.

Neither display performs well outdoors in bright sunlight, a perennial challenge for ultracompacts then and now, so an optional hood or shaded angle helps.

Autofocus and Performance: Speed, Accuracy, and Tracking

Autofocus systems profoundly shape user experience - catch it right, and many shots become effortless.

Nikon S4000: Features a single, center contrast-detection autofocus area; it locks quickly under ample light but struggles in low-light or on low-contrast subjects. No face or eye detection means relying on framing to avoid misfocusing.

Sony T90: Incorporates 9 autofocus points with multi-area AF options, improving composition flexibility and tracking accuracy for varied subjects. Contrast detection again, but with added manual focus control, which can save a shot in tricky situations.

Continuous shooting rates are modest: Nikon hits 3 fps max, Sony 2 fps. Not ideal for sports or wildlife action but sufficient for casual bursts.

Zoom Lenses: Reach, Aperture, and Versatility

Both cameras have a fixed lens with 4x optical zoom and similar focal length multipliers (~5.8x crop factor).

Nikon’s 27mm wide angle is excellent for landscapes, architecture, and group shots, giving a wider field of view than Sony’s start of 35mm. Sony’s lens extends further out to 140mm equivalent, beneficial for moderate telephoto, but the small max aperture at that range limits available light capture and bokeh quality.

Optical image stabilization (OIS) is present only in Sony’s T90, vital for handheld telephoto shooting, while Nikon lacks stabilization altogether - a significant disadvantage when shooting zoomed-in without a tripod.

If you value telephoto reach and stability, Sony edges ahead here. For wide-angle versatility or general snapshots in well-lit situations, Nikon’s lens is more forgiving.

In Different Photography Genres: Strengths and Limitations

Let’s apply this knowledge across the photographic spectrum to see where each camera shines or falls short.

Portrait Photography

Skin tones, bokeh quality, eye detection?

• Nikon S4000: The warmer color rendition is appealing for skin tones, producing gentle, flattering portraits, especially in natural light. However, lacking face or eye detection autofocus means you must be careful with focus placement, especially at wider apertures for shallow depth.

• Sony T90: Slightly cooler hues can be adjusted in post, but the added manual focus opportunity helps precision in tight compositions. Unfortunately, telephoto aperture of f/10 limits background blur significantly, yielding flatter bokeh.

For casual portraits, Nikon is slightly more friendly, but serious portraitists may find both insufficient for professional work.

Landscape Photography

Dynamic range, resolution, weather resistance?

Both share similar sensors and lack weather sealing, so shoot with care outdoors in adverse conditions.

• Nikon’s 27mm wide angle and brighter aperture favor sweeping landscapes and detailed scenes in daylight. The Expeed C2 processor helps maintain subtle tonal gradations in skies and foliage.

• Sony’s 35mm start is tighter, more telephoto leaned, limiting framing options for grand vistas. Lower aperture and less refined dynamic range reduce landscape appeal.

Winner here: Nikon S4000 for landscapes.

Wildlife and Sports Photography

Autofocus speed, burst rates, telephoto reach?

Neither camera was designed for fast action, but:

• Sony T90’s 9-point AF and optical stabilization aid in tracking moving subjects and handholding at the longer zoom - good enough for casual wildlife or amateur sports snapshots.

• Nikon S4000’s single AF point and lack of stabilization weaken performance in these genres. Faster continuous shooting rate (3 fps vs 2 fps) doesn’t compensate for limited focusing.

If wildlife or sports are major priorities, Sony holds a small advantage, but neither is a dedicated solution.

Street Photography

Discreetness, portability, low-light?

Both weigh under 150 grams and fit in a pocket - a tick on discreetness and portability.

• Nikon is slightly thicker but has quicker auto-focus locking.

• Sony’s slimmer build snaps shut quickly for street moments but has lower low-light capability due to a narrower max aperture and smaller display resolution for quick framing.

Nikon edges out here for fast casual street snaps; Sony’s discretion and manual focus could appeal more to enthusiasts comfortable with tweaking settings on the fly.

Macro Photography

Magnification, focusing precision, stabilization?

• Nikon’s close focusing distance of 8 cm offers satisfying macro shots with a reasonable working distance inwell-lit conditions.

• Sony’s macro focusing data is unspecified, but manual focus ring allows some finesse if autofocus struggles.

Sony’s optical stabilization helps handheld macro shots, while Nikon requires support. Overall, Nikon marginally better for casual macro shooters.

Night & Astrophotography

High ISO, exposure modes?

Both max out at ISO 3200, but noise renders images grainy past ISO 800.
