Sony NEX-5 vs Sony A33: An Experience-Driven Camera Showdown for Enthusiasts and Pros Alike

Choosing your next camera can feel like navigating a dense jungle - with many forks and false trails along the way. Today, we step into that jungle armed with over 15 years of camera testing experience to compare two notable early-2010s Sony models: the mirrorless Sony NEX-5 and the entry-level DSLR-style Sony A33. Both offer 14MP APS-C sensors and carry a similar price footprint (though the A33 often emerges as the cheapskate’s more affordable pick).

If you’re after a heavily hands-on, straight talk on how these cameras perform in the wild - whether snapping portraits, shooting landscapes, capturing wildlife action, or shooting video - this comprehensive comparison has you covered. By the end, you’ll clearly know which camera sticks around for your unique photographic journey and which might drain your wallet without satisfying your needs.

Let’s start by sizing them up.

Getting Physical: Size, Handling, and Ergonomics

When thickness and weight matter, few things speak louder than actual grip feel and camera build. The Sony NEX-5 is distinctly the petite, rangefinder-style mirrorless contender at 287g and a boxy 111x59x38mm footprint. In contrast, the Sony A33 is a beefier compact SLR with a heftier 500g weight and overall size of 124x92x85mm.

In my decade-plus shooting experience, smaller cameras like the NEX-5 often charm street photographers and travelers who prize pocketability and discreetness. The lack of a built-in electronic viewfinder (EVF) does come at a cost under bright daylight, but the compact dimensions are a real plus when you’re commuting with fewer clubs for your thumbs.

On the other end, the A33’s DSLR-style body boasts a deeper handgrip and a more substantial, confident feel. The feel of physical dials and buttons is more tactile, especially when shooting with gloves or in less-than-ideal weather. Yes, at half a kilo plus bulk, it’s not a featherweight, but proper handling often beats pocketability in professional settings - especially when paired with heavier glass.

Controls and Interface: How Do These Cameras Talk to You?

Sony’s UI decisions on these cameras show deliberate design differences. The NEX-5 opts for streamlined controls with its tilting 3-inch screen, though it lacks the textured wheels or a top LCD common on more advanced gear. There are no illuminated buttons, and the rear buttons require some moving around if you’ve got bigger hands or when you’re juggling quick mode swaps - something I’ve often found mildly frustrating during event shoots.

The A33 counters with a robust cluster of physical controls, including dedicated dials for exposure compensation and shooting modes. The fully articulated 3-inch screen has a slightly higher resolution (921 vs. 920 pixels, which is negligible in real-world use) and flips around for self-portraits or awkward shooting angles - something vloggers and video shooters will appreciate.

Its electronic viewfinder is a notable addition, providing 100% coverage and decent 0.73x magnification, making critical focus checking easier in outdoor sunlight or fast-paced scenarios where LCD glare is a non-starter. For mirrorless advocates, NEX-5’s screen is a strong live view interface, yet compared to the A33’s confidence-inducing EVF, it can feel limiting.

Sensor and Image Quality: More Than Just Megapixels

Here's where things get technically juicy. Both cameras share a close APS-C sensor, around 23.5x15.6 mm, sporting 14 megapixels with an anti-aliasing filter. Classic Sony CMOS tech paired with Bionz processors underpins their imaging pipelines.

The slight edge goes to the A33 in DxO Mark scores (70 overall vs. 69 for the NEX-5), buoyed by improved dynamic range (12.6 vs. 12.2 EV stops) and better color depth (22.8 vs. 22.2 bits). The A33 also supports ISO up to 25600 (boosted) vs. 12800 max on the NEX-5, but as you’d expect for cameras this vintage, high ISO performance dips noticeably above ISO 3200.

In practical terms, this translates to slightly richer colors and a touch more latitude for recovering shadows in tough lighting - beneficial in landscapes and portraits where skin-tone gradation matters. Both cameras benefit from Sony’s APS-C sensor’s inherent strengths compared to smaller Four Thirds or point-and-shoot sensors: noise control and resolving power.

But don’t let subtle lab test numbers fool you. In my field tests, these differences are noticeable but subtle; both cameras produce solid 14MP output with decent detail and manageable noise below ISO 1600. For high-res prints or aggressive cropping, expect similar results.

Looking at the Back: Screens and Viewfinders for Composing Shots

Access and visibility through the LCD or viewfinder are critical in the field. The NEX-5’s tilting screen is limited to about 90 degrees upwards and 45 downwards - a plus when shooting low or awkward angles but less flexible than the A33’s fully articulated screen that flips completely out and around.

Granted, the lack of an EVF on the NEX-5 means you'll rely heavily on the rear screen, which can struggle against harsh sunlight. The A33, with its EVF built right in, allows through-the-eyepiece shooting - a boon for static-focused photographers, sports shooters, or anyone working outdoors. Its electronic finder, while not the highest resolution by today’s standards, gives you that framing security and shot confidence, allowing better manual focusing and exposure preview.

If, like me, you often shoot on-location and need reliable framing aids, that EVF tip certainly balances the scales in A33’s favor.

Autofocus Systems: Speed, Accuracy, and Practicality

Both cameras sport contrast-detection autofocus as a baseline, but the A33 benefits from phase detection autofocus native to its translucent mirror design, boasting 15 focus points with 3 cross-type sensors. The NEX-5 relies on 25 contrast-detection points.

What does this mean for you shooting portraits, sports, or wildlife? The A33’s phase detection delivers faster, more accurate autofocus, especially in tracking moving subjects. I found it confidently locked onto faces and fast action sequences, though it lacks the subject-recognition smarts seen in modern mirrorless - no animal eye AF here.

Contrarily, the NEX-5’s contrast AF is more deliberate and can hunt in low light, making it less suitable for rapid sports or wildlife photography but perfectly viable for controlled portraits and street photography where decisive AF isn’t mission critical.

Neither camera supports face or animal-eye AF tracking; however, the A33 supports face detection, giving portrait shooters a slight edge. Both perform admirably in studio lighting, but outdoors, the A33’s hybrid AF system gives it that coveted edge.

Burst Shooting and Buffer: Catching Those Fleeting Moments

With both offering 7 frames per second continuous shooting, expectations are high for quick bursts. In practice, buffer depth and write speeds matter enormously.

The A33, with its SLT translucent mirror design, achieves 7fps with continuous phase detection AF, making it a surprisingly spry camera for action shooters in its class. However, buffer length caps you once the memory fills.

The NEX-5 also matches 7fps but drops AF tracking to single focus mode during bursts, which limits its utility for fast subjects.

As a wildlife or sports photographer who often needs precise AF during high-speed sequences, I found the A33 a better workhorse capable of delivering more in the heat of the moment.

Connectivity and Storage: What’s Plugged In?

Both cameras feature USB 2.0 for transferring files and HDMI outputs for external monitoring or playback. However, neither supports Bluetooth, NFC, or Wi-Fi - something modern users might lament but was typical for 2010 gear.

The A33 does have “Eye-Fi” card connectivity - a proprietary method allowing wireless picture transfer with certain SD cards - which might appeal to some but is limited now due to outdated card support.

Storage-wise, both rely on a single SD (plus Memory Stick) slot supporting SDHC/SDXC cards. Battery life is similar, with the A33 marginally edging out the NEX-5 by about 10 shots per charge (340 vs. 330), likely due to the hybrid mirror mechanics-plus-evf system.

Video Capabilities: Not Just Snapshots Anymore

With the rise of hybrid photo/video users, camera video features are vital. Both cameras deliver 1080p Full HD footage at 60fps (though A33’s frame rates adjust between 60 and 29.97fps depending on format), with AVCHD and MPEG-4 formats.

Audio input is where the A33 shines: it sports a microphone port absent on the NEX-5, giving content creators room to attach external mics, yielding cleaner, richer sound. The NEX-5 lacks mic or headphone jacks, limiting your audio control.

Stabilization-wise, the A33 includes sensor-based image stabilization (IBIS), invaluable when shooting handheld videos or using non-stabilized lenses. The NEX-5 relies solely on lens-based stabilization - nonexistent in many E-mount primes - so video is more prone to shake.

The fully articulated screen on the A33 is a boon here, especially for vloggers or run-and-gun shooters needing flexible framing.

Photography Genres: How Do These Cameras Perform Across the Board?

Let’s break down where each camera excels or falls short across popular photography types.

Build Quality and Weather Sealing: Can These Cameras Take a Beating?

Neither the NEX-5 nor the A33 offer official weather sealing or ruggedized exteriors. The A33’s bigger body feels more solid and confident in handling rough conditions, but both cameras need care around moisture and dust.

Professionals should consider protective covers or look elsewhere if environment sealing is a dealbreaker.

Lens Ecosystem: Which Camera Has the Better Glass?

Sony’s E-mount on the NEX-5 launched a vibrant lens ecosystem - even today, its native mirrorless lenses are known for optical quality and innovation. Sony had about 121 compatible lenses at the time.

The A33 uses the Sony/Minolta Alpha mount with 143 lenses - covering many legacy Minolta lenses and third party options. This veteran lens base offers variety, but many older lenses lack modern coatings and autofocus tech.

If lens versatility and access to modern autofocus primes matter most, the NEX-5’s E-mount is a smart bet for mirrorless shooters. However, those invested in legacy lenses might prefer the A33’s mount.

Battery Life and Storage Revisited

While both cameras run on the same battery model (NP-FW50), the A33's slightly higher watt-hour efficiency nets marginally longer shooting per charge - 340 shots vs. 330 for the NEX-5.

Both use a single SD plus Memory Stick slot, though I recommend focusing on fast SDXC cards for quicker write speeds, particularly important when shooting RAW or continuous bursts.

Price and Value: Which Camera Maximizes Your Budget?

Street prices reveal a stark contrast. The NEX-5 typically hovers near $600 new (now largely discontinued), while the A33 can be found around $230 in used or clearance markets.

From a pure value perspective, if you’re looking to stretch pennies and snag decent performance for portraits, travel, or beginner wildlife, the A33 is an excellent bargain.

The NEX-5, however, rewards those craving lightweight portability, newer lens designs, and the future-proof mirrorless interface - albeit at a higher cost.
