How to choose a flash or speedlight
Good light is the fastest way to make a photo look professional, and a flash is the most portable way to get it. Here's how to choose and use one.
On-camera or off-camera?
A speedlight on your hot shoe is convenient and great for fill, events, and bounce flash off a ceiling. Taking that same flash off-camera — on a stand, fired wirelessly — is what produces directional, three-dimensional light and separates snapshots from portraits. Most photographers start on-camera and quickly add a trigger to go off-camera once they see the difference.
TTL vs. manual
TTL (through-the-lens) metering sets flash power automatically and is ideal for run-and-gun events where the distance to your subject keeps changing. Manual gives you a fixed, repeatable output for consistent results in controlled setups like portraits and product work. The best modern flashes do both, so you can learn on TTL and grow into manual.
Guide number, recycle time, and power
Guide number measures raw power — higher means more reach and more ability to overpower the sun outdoors. Recycle time is how fast the flash is ready for the next shot; slow recycling costs you moments at events. Battery type matters here: many photographers prefer lithium-ion flash packs for faster recycling and far more shots per charge than AAs.
Don't forget modifiers and triggers
A bare flash is hard light. Softboxes, umbrellas, and diffusers shape it into something flattering, and a wireless trigger system unlocks off-camera and multi-light setups. Buying into a system with affordable modifiers and reliable wireless — Godox is the popular value choice — keeps your future options open.
Frequently asked questions
What's the difference between a flash and a speedlight?
Speedlight is just the common name for a portable, on-camera-style flash that mounts to your hot shoe. Flash is the broader term that also covers larger studio strobes. For most photographers starting out, a speedlight is the flash you want.
Do I need TTL, or is manual fine?
TTL is worth it for events and anything where your subject distance changes constantly — it sets power for you. Manual is better for controlled work where you want identical output shot to shot. Most current flashes offer both, so you don't have to choose permanently.
Will a third-party flash work on my camera?
Yes, as long as you buy the version made for your camera's mount and TTL system — Canon, Nikon, Sony, Fujifilm, and others each use a different protocol. Brands like Godox sell mount-specific versions and matching triggers. Tell us your camera and we'll make sure you get the right one.
What else do I need besides the flash?
To get off-camera, you'll want a wireless trigger, a light stand, and a modifier — a softbox or umbrella to soften the light. A spare set of batteries or a lithium pack keeps you shooting. Many flashes are sold in kits that bundle the essentials.
Should I buy new or used?
Flashes can be a good used buy, but they do wear — heavy event use ages the flash tube and electronics. If you buy used, get it from someone who has tested it fires reliably at all power levels. Our used lighting is inspected and tested in the shop before it goes on the shelf.
