A speedlight is a compact flash that mounts on a camera hot shoe or sits off camera on a stand. Models differ in power, supported camera systems, modes and wireless control, which makes compatibility the first thing to check. We have not used these products ourselves, so this guide focuses on how to read the specifications and what to compare.
Begin with your camera system and what you shoot, whether that is events, portraits or travel. Then compare power, modes, zoom range, recycle time and the way the flash is controlled. The table below lists each factor and what to check. Figures for power and recycle time come from the maker and depend on the settings used, so read the conditions. Check whether the flash supports automatic exposure with your camera or only manual control, since this decides how easily you can use it.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Compatibility | Decides whether features work with your camera | Look for the camera system named in the listing and any firmware notes |
| Guide number | Gives a rough measure of output | Compare the stated figure and the zoom position and ISO it assumes |
| Modes | Affects ease of use | See whether TTL, manual and high speed sync are supported |
| Zoom head | Changes the spread of light | Check the focal length range and the swivel and tilt angles |
| Recycle time | Matters for fast shooting | Look at the stated time at full power and the battery type used |
| Wireless control | Needed for off-camera work | Check radio or optical control and whether a transmitter is included |
Setup and Care Tips
- Match the flash to the hot shoe of your camera before mounting it.
- Use fresh batteries of one type, and swap them as a set.
- Try bounce flash off a white ceiling or wall for softer results.
- Let the flash cool down after long bursts at full power.
- Remove the batteries for long storage.
Mistakes to Avoid
- Buying a flash made for a different camera system.
- Judging power by guide number alone.
- Mixing old and new batteries.
- Skipping firmware updates the maker offers.
- Forgetting a stand or adapter for off-camera use.
FAQ
Do I need TTL?
TTL lets the camera and flash set exposure automatically. Manual modes give you more control, and many people use both depending on the scene.
Can I use a flash from a different brand?
Some work in manual mode on other cameras, but automatic features may not. Confirm compatibility in the listing before ordering.
The Short Version
Confirm camera compatibility first, then compare power, modes, zoom head and recycle time. Decide whether you need wireless control, and treat power and speed figures as the maker’s own numbers. Think about how you will power and carry the flash, and whether a diffuser or a second unit would suit your work later. Write down the lenses and the rooms you shoot in most, then match the zoom range and bounce angles to them. Ask whether the battery type is easy to find while traveling, and check that the listing names the exact hot shoe and mount type for your camera body.
