A speedlite is perhaps the cheapest way to make your photos take a big leap forward. Buying used, you can often pick up a flash or trigger for a considerably lower price than new, and in this category in particular that pays off: the technology ages slowly and a well-maintained flash lasts for years.
What should you look out for with a used speedlite?
The most important things are the mounting foot (hot shoe) and the TTL communication with your camera. A flash for Canon doesn't automatically talk to a Nikon or Sony, so always check for the right mount — that's why we also divide the range by brand. Also pay attention to the condition of the zoom head, the contacts on the foot, and whether the flash window is still clear. A flash that has been heavily used in studio work may have a discoloured tube; for occasional use that matters little.
Remotes and triggers
With remote controls it's mainly about compatibility. A wireless shutter release or trigger is tied to a specific system or port, so choose by camera brand and connection. If you want to control several flashes off-camera, you need a transmitter that matches your flash brand — Godox has its own wireless system, Canon works with the RT line, for example in combination with the Canon ST-E3-RT Speedlite Transmitter.
Who is it for?
Beginner photographers often pick up an entry-level speedlite to get better light indoors or at events. Those who want to go further with portrait or product photography move on to off-camera flash with triggers. Macro photographers will find ring and twin flashes here too. If you're looking for a reliable recommendation, your best bet is the Nikon SB-910 Speedlight, the Canon 600EX-RT Speedlite or the Canon Speedlite 600EX II-RT. Every item is professionally inspected and comes with at least 12 months' warranty, and you have a 14-day return period — that way you buy used equipment without the guesswork.
