Buying Guide
- Compatibility matters: Check your camera’s hot shoe type (single-contact vs. multi-pin). Some mini flashes only work with select brands or require manual triggering.
- Power and range: Higher guide numbers deliver brighter light over a longer distance. If you shoot in large rooms or outdoors, prioritize higher output.
- Manual vs. automatic modes: Manual control offers consistency, while S1/S2 modes provide simple off-camera trailing light without TTL. Consider your comfort with exposure settings.
- Size and portability: Travel-friendly kits benefit from compact, lightweight units. Balance size with enough power for your typical subjects.
- Sensor features: Auto pre-flash sensors enable easier triggering in chaotic lighting, but verify reliability with your camera body.
- Durability and batteries: Battery type (AA vs. proprietary) affects running costs and availability on location.
- Future expansion: If you expect to upgrade bodies or add more lights, choose flashes with consistent triggering and compatibility across brands.
FAQ
- What is a slave flash? A slave flash is triggered by another flash or sensor rather than directly by the camera’s own hot shoe.
- Do all slave flashes support TTL? No. Many entry-level or mini models rely on manual exposure or non-TTL triggering.
- Can I use a slave flash with any camera? Compatibility depends on the hot shoe type and whether the unit supports your camera’s triggering method.
- Is a higher GN always better? Higher GN provides more power, but you may not need it in small spaces. Choose based on typical shooting distance and subjects.
- Which mode is easiest for beginners? S1 or S2 modes (non-TTL) are usually the simplest for automatic secondary lighting effects.
- Should I buy multiple slave flashes? If you regularly shoot with multiple lighting angles or backdrops, adding multiple slaves can improve lighting control.
