Buying Guide
What should you consider when choosing a flash for 35mm cameras?
- Compatibility: Confirm your camera’s hot shoe type (single-contact vs. TTL-capable) and whether the flash supports it.
- Power and output: Higher guide numbers deliver more light, useful for outdoors or larger scenes. Consider GN33 or GN15 as common reference points.
- Modes and control: Manual mode offers predictable exposure; S1/S2 modes work with master flashes for creative timing. TTL is not universal in these models, so plan accordingly.
- Portability: Mini or compact speedlites are ideal for travel; larger units offer more power but add weight.
- Rotation and bounce: Degree of vertical and horizontal rotation affects lighting angles and shadow control.
- Brand and ecosystem: If you already shoot with a specific system, prefer a flash known to work with your brand’s bodies and lenses.
Practical buyer questions
- Do these flashes support TTL? Most listed models do not; they rely on manual or S1/S2 modes.
- Will a compact flash work with my camera? Check hotshoe type and compatibility lists for your camera model.
- Is versatility better than high power? For many setups, a balance of power, control, and size yields the best results.
- Should I buy one flash for all my cameras? If you own multiple brands, a multi-brand unit with broad compatibility is convenient but verify model-specific compatibility.
- What about off-camera use? Some models include slave or PC sync options; others are best used on-camera.
- Are there any caveats with Sony ZV models or Rebel DSLRs? Some units list compatibility limitations; verify model-by-model before purchase.
