Seeing the Cameras in Hand: Size, Handling, and Control Layout

Your camera is an extension of your creativity, so physical feel and usability matter as much as image quality. Let’s start by sizing up the Nikon D3400 vs the Sony SLT-A35.

• Nikon D3400: Compact and lightweight at 395g, featuring a traditional DSLR body with well-defined grip and weather-resistant build absent (typical for entry-level). Its form is comfortable for extended handheld use despite modest dimensions (124x98x76 mm). I particularly appreciated how its textured grip and straightforward button layout make it approachable for beginners and steady in the field.

• Sony SLT-A35: Slightly heavier at 415g with a marginally deeper and taller profile (124x92x85 mm), due to being an early-generation translucent mirror camera (Single-Lens Translucent - SLT). The grip is ergonomic but a touch less substantial than Nikon’s, which may affect prolonged handling comfort. The build lacks weather sealing, similar to the D3400.

Ergonomics also hinge on button placement and usability, so let's look from above.

Here the Nikon impresses with simplicity - top-plate controls focused on shooting modes and exposure compensation, intuitive for beginners. The Sony offers more buttons aimed at quick toggling, catering to users who want faster access to customizable settings but possibly overwhelming newcomers.

Summary: If you prize a lightweight, straightforward handling experience, the Nikon D3400 is a winner. The Sony A35 aims at slightly more tactile control but demands a bit more familiarity.

Sensor and Image Quality: The Heart of Your Photography

Both cameras use APS-C sized CMOS sensors measuring 23.5 x 15.6 mm - a proven format balancing image quality and cost. But sensor resolution and processing can differ notably.

• Nikon D3400: Sports a 24.2-megapixel sensor without an anti-aliasing filter, allowing it to capture incredibly sharp details for an entry-level DSLR. Paired with the Expeed 4 processor, it delivers excellent dynamic range (~13.9 EV) and impressive color depth (24.8 bits) per DxOMark testing. Its low-light ISO performance is remarkable for its class, with usable results up to ISO 3200 and clean enough up to 6400 for most situations.

• Sony SLT-A35: Features a 16.2-megapixel sensor with a traditional anti-aliasing filter to reduce moiré artifacts at the cost of slight detail softening. The Bionz processor handles image rendering with decent color depth (~23.3 bits) and dynamic range (~12.7 EV). Low-light capability is acceptable but lags behind Nikon, showing more noise at ISO 1600 and above.

Hands-on observation: In real shooting conditions, the D3400’s higher resolution and cleaner high-ISO images provide better cropping flexibility and print size. The Sony’s images appear a touch smoother, but detail loss is evident when zoomed in.

Viewing and Composing: Optical vs Electronic Viewfinders

Your viewfinder choice affects framing precision and usability across lighting conditions.

• Nikon D3400: Uses an optical pentamirror viewfinder with 95% frame coverage and 0.56x magnification. This means you see through the lens optically but lose a bit of framing accuracy. The brightness is natural and responsive, although in low light the viewfinder darkens.

• Sony SLT-A35: Incorporates a 1,150k-dot electronic viewfinder (EVF) covering 100% of the frame with 0.73x magnification. This provides an exact preview of exposure, white balance, and depth of field before shooting - an advantage for manual settings.

Both cameras have fixed 3-inch LCD screens with 921k dots - sharp but non-touch. The Nikon’s screen surface is matte, reducing reflections outdoors, while Sony’s is glossy but more vibrant. Neither has articulating or tilting abilities for difficult angles.

Personal take: The Nikon’s optical viewfinder offers lag-free, natural viewing with minimal battery drain - classic DSLR handling. The Sony’s EVF is ahead of its time for 2011, letting photographers see settings in real-time, great for pre-visualization but less natural and more battery intensive.

Autofocus, Burst Rates, and Shooting Speed: Capturing the Moment

For photographers chasing action or wildlife, autofocus system and continuous shooting speed are pivotal.

Autofocus System

• Nikon D3400: Features an 11-point phase-detection autofocus system with a single cross-type sensor. Face detection is supported in live view via contrast detection. It uses the Expeed 4 processor to track subjects reasonably well but lags in complex scenes with fast-moving subjects.

• Sony SLT-A35: Has a more advanced 15-point phase-detection AF with three cross-type points and proprietary Translucent Mirror Technology allowing continuous autofocus even during continuous shooting. However, it lacks predictive tracking (no AF tracking), which limits accuracy in erratic subject movement.

Burst Shooting

• Nikon D3400 shoots at up to 5fps - adequate for casual sports or wildlife snapshots.
• Sony A35 edges slightly ahead with 6fps continuous shooting, enabled by the fixed translucent mirror.

Experience note: In field tests photographing fast birds and soccer games, Nikon’s AF struggled occasionally with subject lock-on, while Sony’s AF was snappier but sometimes faltered due to limited tracking sophistication.

Lens Ecosystem and Compatibility: Building Your Kit

A camera is only as good as the lenses it can use. Both systems leverage their respective legacy mounts.

• Nikon D3400: Uses Nikon F-mount with a vast pool of over 300 lenses - from affordable primes to advanced telephotos, including third-party options. Note the D3400 lacks an internal autofocus motor, so it needs lenses with built-in motors for AF (AF-S or AF-P lenses).

• Sony SLT-A35: Employs Sony/Minolta Alpha mount with around 143 native lenses available. The selection is more limited, with fewer third-party options compared to Nikon. However, compatibility with Minolta AF lenses offers some catalog breadth.

Pro tip: If you plan on expanding your lens arsenal significantly, Nikon's F-mount availability is more attractive, offering higher flexibility and better resale value.
