Sony A6400 (16–50mm) Cheat Sheet

Camera and Photography Tips
Written By Sneha Mukherjee

Landscape Photography

  • Mode: Aperture Priority (A) or Manual – control depth-of-field and exposure. Set aperture first for sharpness.

  • Aperture: ~f/8–11 (landscape “sweet spot”) to maximize sharpness/DOF. Stop down for greater DOF; avoid extremes (f/22+ softens, f/1.4–5.6 blurs foreground).

  • Shutter: On tripod, use slow speeds as needed (seconds). Handheld: ≥1/(focal length) rule (≈1/50 s at 50 mm).  If no tripod, keep shutter ≥1/60–1/100 s to avoid blur. 

  • ISO: Use base ISO 100 for best image quality.  Only raise ISO if absolutely needed for exposure.

  • Focal: Use wide end (16–24 mm) for broad vistas. Zoom moderately (24–35 mm) to include foreground interest. Avoid heavy tele (50 mm) which narrows view.

  • AF Mode: AF-S (Single-shot) or Manual – focus ~1/3 into scene or on distant subject. Use small AF point/central AF for precision. (Manual-focus infinity is fine for static distant scenes.)

  • Drive: Single or 2 s timer – avoid camera shake. Use self-timer or remote shutter release if on tripod.

  • Stabilization: If handheld, enable OSS (Optical SteadyShot) on the 16–50. If on tripod, turn OSS Off to prevent blur. 

  • Notes: Use a sturdy tripod/level camera. Consider bracketing or HDR for high-contrast scenes. Check histogram/Live View. Lens sharpest mid-aperture – prioritize aperture then shutter. 

Portrait Photography

  • Mode: Aperture Priority (A) or Program – control depth-of-field. Let camera pick shutter and ISO. (Manual mode can work too if comfortable.)

  • Aperture: Wide as possible: kit lens max f/3.5 at 16 mm (use longer focal for portrait geometry), or f/5.6 at 50 mm. Lower f-number for subject isolation. Example: outdoors try f/4–5.6 on the long end.

  • Shutter: Fast enough to freeze subject motion: typically ≥1/100 s (50 mm eq. on APS-C) or faster. Use the “double focal length” rule: e.g. 50 mm→~1/100–1/160 s. If subject is moving, increase shutter.

  • ISO: Start low (100–400). Let camera raise ISO if needed, but be mindful of noise. The A6400 handles up to ~3200–4000 fairly well, but try to stay below that if possible.

  • Focal: Longer end (30–50 mm) gives flattering perspective and background blur. Zoom in (50 mm) for headshots; 24–35 mm for environmental portraits (mind distortion at very wide angles).

  • AF Mode: Real-time Eye AF on the A6400 – it constantly tracks eyes for pin-sharp focus.  Use AF-S (Single-shot) for posed/steady subjects, or AF-C (Continuous) if subject moves.  Flexible Spot or Center-AF area aimed at the subject’s face is ideal.

  • Drive: Continuous L/Continuous H if shooting action/children to catch decisive moments; Single-shot for static poses.

  • Stabilization: Keep OSS on if handholding (at f/3.5–5.6, a slightly slower shutter can be handled). Use a monopod or tripod for static groups.

  • Notes: Focus on the eyes! Position subject well-lit (natural light or soft flash) and use portrait orientation. Leave headroom/composition space. For extra blur, crop tightly or step in closer.

Street Photography

  • Mode: Aperture Priority (A) – quick control of aperture while camera handles exposure. This lets you concentrate on composition.

  • Aperture: Medium (~f/5.6–8). StreetSnappers recommends f/8 for good DOF. Smaller aperture (f/11–16) if bright conditions and lots of layers. Avoid extremely wide apertures (f/3.5–4) unless you want very shallow focus.

  • Shutter: Fast: set a safe minimum shutter (e.g. 1/125–1/250 s). StreetSnappers uses 1/200 s min. If moving/low light, use Auto ISO with a 1/125–1/200 s floor to prevent blur. (As a rule, try ≥1/(focal length) or better.)

  • ISO: Auto ISO range ~200–3200 (day).  Let ISO rise for dark scenes rather than slow the shutter. StreetSnappers sets Auto ISO 200–3200 with 1/200 s floor. In practice, stay as low as possible for quality, but allow up to ~3200.

  • Focal: Mid-range (24–35 mm on APS-C ≈ 35–50 mm FF) for natural look and quick framing. 16 mm for close, dramatic scenes; 50 mm for more isolated shots or details.

  • AF Mode: AF-C (Continuous) for moving people; AF-S (Single) for stationary subjects. Always enable Face/Eye-detection if shooting people – A6400’s Real-time Eye AF works in many situations. Use Flexible Spot or Expand AF area so camera focuses on your chosen subject. 

  • Drive: Continuous burst (CL/CH) to capture fleeting moments. Single-shot if holding camera to eye and composing more carefully.

  • Stabilization: OSS On to help at slower speeds (especially if panning). Consider a fast prime (though kit has no prime) or imagine a hidden tripod – keep steady.

  • Tips: Keep camera ready (no fiddling!). Zone focus (pre-focus) is an option with small apertures. Blend into scene; patience is key. Use Exposure Compensation on the fly for contrasty street light.

Low-light / Indoor Photography

  • Mode: Manual (M) or Aperture Priority (A). Manual gives full control; in A-mode set a safe minimum shutter/ISO in the menu. Avoid full Auto mode (it may push ISO very high).

  • Aperture: As wide as possible: kit’s max (f/3.5 @16mm, f/5.6 @50mm). Use lowest f-stop to gather light and blur background. (If lens f/2.8 is available, even better.) In low light, opening up is priority. 

  • Shutter: Fast enough to avoid blur: at least 1/60–1/125 s for handheld. For portraits indoors, target ~1/100–1/200 s. Remember the rule: shutter ≈1/(2×focal length) or faster for sharpness (e.g. 50 mm→≥1/100 s). Use tripod or stabilize if you must go slower.

  • ISO: Raise ISO as needed for exposure, after aperture and shutter are set. Start at 400–800 and increase (e.g. up to ~3200) if scene is too dark. Try to keep ISO ≤3200–4000 on A6400 to control noise. In Manual mode, set Auto ISO upper limit (e.g. 3200) and a minimum shutter (e.g. 1/60 s).

  • Focal: Use what suits the scene. 16–24 mm for wide room shots, 50 mm for isolated portrait indoors. Longer focal may need higher ISO or faster shutter.

  • AF Mode: AF-S is fine for still subjects; AF-C if people move. Face/Eye AF can work if light allows. In very low light, consider manual focus or Focus Magnifier for precision.

  • Drive: Single-shot or 2 s timer to avoid shake. Use self-timer (2s or 10s) if on tripod to eliminate shutter-jitter.

  • Stabilization: Keep OSS On when handheld (it helps at slower speeds). On a tripod, turn OSS Off. Use a tripod or monopod for sharp shots at >1/60 s.

  • Tips: If possible add external light (flash, lamp). Use RAW and noise reduction in post. If capturing static scenes (night cityscapes), switch to manual bulb or long exposure. Keep camera steady: brace elbows, lean on something.

Video Shooting (Vlogging / Cinematic / Casual)

  • Mode: Manual (M) or Shutter Priority (S) is preferred. In Manual, set shutter/aperture yourself; in S-mode fix shutter (camera picks aperture). Avoid full Auto for consistency.

  • Framerate: Commonly 24p or 30p for natural motion. For slow-motion use S&Q mode (60p or 120p in camera).

  • Shutter: Follow the 180° rule: shutter ≈2× framerate. E.g. at 24p use 1/50 s; at 30p use 1/60 s. (1/100 at 50p, 1/250 at 120p, etc.)

  • Aperture: Wide open (kit ≈f/3.5) for maximum light and shallow DOF (cinematic blur). If too bright, add ND filter or close down aperture with ISO/lighting adjustments.

  • ISO: Use lowest practical ISO: set to Auto with low ceiling or Manual low (e.g. 100–800). In general, “lowest ISO possible” for clean footage. 

  • Focal: Vlogging: wide end (16–24 mm) to fit yourself and background. Cinematic: vary – use 50 mm end for tighter shots or creative framing. For casual, any focal works (auto-zoom, etc.).

  • AF Mode: AF-C (Continuous) in movie mode. Use Face/Eye detection (Real-Time AF works in video too) to keep subjects sharp. Disable AF speed smoothing for faster response if chasing focus. Manual focus + focus peaking is often used for cinematic footage.

  • Stabilization: Turn OSS On for handheld or use a gimbal/tripod. The A6400 has no IBIS, so for smooth pans, use steady hardware (gimbal, monopod, shoulder rig).

  • Drive: N/A for video (video record mode). But for handheld, use a sturdy grip or rig.

  • Vlogging Tips: Flip-up screen for framing. Keep camera at eye level or use chest mount for dynamic feel. Use an external mic on hot-shoe or connector.

  • Cinematic Tips: Lock exposure/white balance to avoid flicker. Use a flat picture profile if color grading. Consider 4K for extra cropping or downsampling. Plan shots (storyboarding).

  • Casual Tips: In Auto or Program modes, the camera handles exposure (ISO auto, etc.) – fine for quick clips. Use smooth pans and avoid shaking. Sound: use onboard mic carefully or attach smartphone mic.
