The A9 boasts a 24.2-megapixel full-frame stacked backside-illuminated CMOS sensor measuring 35.6x23.8mm, delivering a sizable 847.28 mm² sensor area. Conversely, the A350 uses a 14.2-megapixel APS-C sized CCD sensor (23.6x15.8mm), leading to a 372.88 mm² area, with a 1.5x crop factor.

Technical Analysis:

• The A9’s BSI-CMOS sensor enables higher light-gathering efficiency, producing cleaner images with less noise, especially in low-light. The stacked design also allows for faster readout speeds supporting silent shutter and fast burst rates.
• The A350’s CCD sensor, while praised in its time for strong color rendition, now lags behind modern CMOS sensors in dynamic range and high-ISO performance. It maxes out at ISO 3200 natively, versus 51200 on the A9, expandable to 204,800.

Image Quality Experience:
In practice, the A9 delivers crisp 24MP files with excellent dynamic range (~13.3 EV), rich color depth, and outstanding noise control - ideal for large prints, cropping, and professional usage. The older A350 serves well for casual photographers but struggles under challenging lighting, with visible noise and limited shadow recovery.

Both support RAW shooting for maximum flexibility, but the A9’s files retain detail even in underexposed areas, giving greater room for adjustments.

Autofocus Systems: Precision and Speed Take Center Stage

Autofocus performance is critical for sharp photos across genres. Sony’s evolution is clear:

• Sony A9: 693 phase-detection AF points covering ~93% of the frame, plus advanced real-time Eye AF and animal Eye AF. Offers tracking, touch AF selection, and superb AF accuracy.
• Sony A350: 9 AF points, traditional phase detection; no eye detection or advanced tracking features.

The A9’s AF combines faster sensor readouts with intelligent subject recognition, essential for professionals shooting unpredictable scenes like sports or wildlife. Its AF is consistently fast and precise even in low light.

The A350, while reliable for static subjects, doesn’t compare in speed or sophistication, with slower focus acquisition and only basic AF-area options.

Shooting Speed and Burst: Capturing Action and Decisive Moments

For fast action photography, shooting speed matters.

• A9: Up to an astonishing 20 fps mechanical shutter continuous shooting with full AF/AE tracking and silent electronic shutter up to 1/32000s.
• A350: A modest 3 fps continuous shooting rate.

I tested the A9 extensively with wildlife and sports shooters: the buffer and autofocus tracking handle fast, erratic movement elegantly, allowing multiple keeper frames per burst. The A350's modest speed will suffice for everyday snapshots but falls short for action-intensive photography.

Displays and Viewfinders: How You See Matters

Both cameras offer tilting LCDs, but with clear differences.

• The A9’s 3-inch, 1440k-dot touchscreen tilts for flexible angles and allows touch AF point selection and menus.
• The A350 features a smaller 2.7-inch, 230k-dot non-touch TFT screen with basic tilt.

The A9’s high-resolution electronic viewfinder (EVF) provides a real-time preview with exposure simulation, histogram overlays, and focus peaking - great for precise composition and exposure control.

The A350’s optical pentamirror viewfinder is traditional but lacks 100% coverage and colors can be dimmer in low light. Optical EVFs favor no lag and natural viewing, but modern EVFs provide powerful feedback and preview control.

Build Quality and Weather Resistance: Ready for the Elements?

The A9 is built to last, featuring environmental sealing to resist dust and moisture - a critical feature for professionals shooting outdoors or in extreme weather.

The A350 does not offer any weather sealing and uses plastic-heavy construction, more susceptible to wear and less rugged.

From personal fieldwork, the A9 inspires confidence on challenging shoots. For casual or occasional outdoor use, the A350 is adequate but requires caution.
