Sony TX200V vs Sony A77: A Hands-on Comparison for Every Photographer’s Needs

Choosing the right camera is a nuanced process, especially when you have two very different models vying for your attention. The Sony Cyber-shot DSC-TX200V and the Sony SLT-A77 may share a brand, but they target vastly different users and use cases. Drawing from my extensive experience testing cameras across genres - from landscape to fast-action sports - I’ll break down how these two stack up, helping you pinpoint which best fits your photography ambitions.

A Matter of Size: From Ultra-Compact to Advanced DSLR

The Sony TX200V is an ultracompact point-and-shoot powerhouse, measuring just 96 x 58 x 16 mm and weighing a mere 129 grams. It’s pocket-friendly, making it a no-brainer for everyday carry, urban street photography, or travel where minimalist gear is key.

Contrast that with the Sony A77, a mid-sized SLR-style body built for more serious shooters. At 143 x 104 x 81 mm and weighing over 700 grams (732g to be precise), it demands a dedicated camera bag and perhaps a passion for full control and advanced operation. The size difference is not only about portability but also ergonomics - the A77 sports deeper grips and external controls tailored for prolonged shooting sessions and versatile handling.

Hands-on with Controls: Which Design Speaks Your Language?

When it comes to control layout, the A77 takes the lead. It features dedicated dials and buttons for shutter priority, aperture priority, exposure compensation, and manual modes, plus a top LCD for quick info scanning. These physical controls appeal especially to enthusiasts and pros accustomed to adjusting settings on the fly.

The TX200V, designed as a user-friendly compact, offers minimal external controls. It does have touchscreen autofocus, but lacks manual focus and professional exposure modes. Its reliance on automatic or semi-automatic shooting modes makes it ideal for casual shooters who want quick snaps without complexity.

Sensor and Image Quality: Sensor Size Discussed in Depth

This is a significant differentiator. The TX200V’s 1/2.3" BSI-CMOS sensor measures about 6.17 x 4.55mm - tiny by any standard - and captures images at 18 megapixels. While this sensor enables high resolution on paper, in my testing, it struggles with noise and detail retention at high ISO values above 800, limiting low-light and dynamic range performance.

The A77’s DSLR-class APS-C CMOS sensor is much larger (23.5 x 15.6mm) with a 24MP resolution, translating into superior image quality. The sensor excels in overall sharpness, color depth, and dynamic range (measured at 13.2 EV at base ISO). It also maintains usable image quality up to ISO 1600 and beyond, outperforming the TX200V substantially in low-light and demanding landscape scenarios.

For portraiture, the A77’s sensor size provides better skin tone rendition and smoother gradation, making it the preferred choice where image quality is paramount.

Viewing and User Interface: OLED vs Articulated LCD

The TX200V boasts a 3.3-inch fixed OLED touchscreen with over 1.2 million dots, providing vibrant colors and excellent contrast in daylight. The touchscreen interface is responsive, perfect for casual users who appreciate tap-to-focus or menu navigation via touch.

The A77 houses a 3-inch fully articulated LCD - though not touch-enabled - with 921,000 dots. While it lacks touch control, the articulated hinge grants extensive flexibility, beneficial for shooting at awkward angles during macro, street, or event photography.

Moreover, the A77 offers an electronic viewfinder (EVF) with 2.36 million dots covering 100% of the frame with 0.73x magnification - a critical advantage for composing in bright light or tracking fast subjects where LCD visibility is compromised. The TX200V omits a viewfinder entirely, requiring reliance on the screen.

Autofocus Systems Tested: Speed, Precision, and Tracking

The TX200V uses contrast-detection autofocus with 9 focus points and face detection. It performs adequately in good light conditions but is noticeably slower in low light or action sequences. The camera lacks phase detection and manual focus options, limiting precision and speed.

The A77 employs a hybrid autofocus system with 19 phase-detection points (11 cross-type), enabling rapid and accurate focus lock, even continuous autofocus for moving subjects up to 12 frames per second. During my hands-on tests with wildlife and sports, the A77’s autofocus consistently outperformed the TX200V, locking onto eyes and faces with confidence and maintaining focus through erratic subject movement.

Real-World Image Samples: A Look at Color, Detail, and Bokeh

Analyzing pictures shot side-by-side reveals the A77’s superiority in resolving fine detail, rendering natural colors, and producing creamy bokeh from fast, compatible lenses. The TX200V’s images are respectable for snapshots but show softness in detail and more noise in shadows, particularly at ISO 400 or higher.

For macro photography, the TX200V can focus as close as 3cm with decent background blur thanks to its 28-140mm equivalent lens, but image quality cannot match the full APS-C sensor of the A77 combined with prime macro lenses. The A77’s lens ecosystem offers over 140 compatible options, from ultra-wide to super-telephoto, enabling creative versatility.

Build Quality and Weather Resistance: Travel and Outdoor Performance

Both cameras feature some level of environmental sealing. The TX200V’s ultracompact body is moderately splash resistant but not waterproof or freezeproof, making it better suited to casual travel use rather than rugged outdoor adventure.

The A77 offers better sealing against dust and moisture, suitable for harsh conditions photographers face in wildlife or landscape work. Its robust magnesium alloy body adds durability but also weight.

Battery life favors the A77 too, rated for 470 shots per charge compared to the TX200V’s modest 220 shots, a factor to keep in mind for prolonged trips without charging opportunities.

Video Capabilities: HD Recording Explored

Both cameras capture Full HD (1920 x 1080) video at 60 fps, with additional lower resolutions available. The TX200V’s video quality benefits from its optical image stabilization to reduce handheld shake, though the built-in microphone and lack of external audio input limit sound quality control.

The A77 shines thanks to its microphone input port, enabling external mics for richer audio capture. The 12fps continuous shooting also makes it attractive for hybrid photo/video professionals. Video enthusiasts looking for manual exposure control during recording will appreciate the A77’s greater flexibility and file format options (including H.264 encoding).

Battery and Storage: Staying Powered and Organized

• TX200V: Uses NP-BN battery pack, powered for about 220 shots per charge; stores images on Memory Stick Duo formats.

• A77: Equipped with the NP-FM500H battery, delivering around 470 shots; supports SD/SDHC/SDXC and Memory Stick Pro formats.

The A77’s better battery life makes it more dependable on demanding assignments. The lack of wi-fi or Bluetooth on both is a downside by today’s standards, though the A77 supports Eye-Fi wireless cards for image transfer.
