A flash for Canon must be compatible with ETTL (II) for automatic exposure control. To get this you don’t have to buy a speedlite from Canon. Alternatives include flashes from Nissin, Yongnuo, Metz, Sunpak, Sigma or Vivitar, to name the main manufacturers.

Below are 2 lists of brands and models with approximate cost, power (guide number), wireless features and links to full specs and in-depth reviews to help selecting your Canon camera flash.

Discontinued Flashes For Canon Digital
External flashes don’t get old and obsolete as quickly as camera bodies. In fact, they maintain their usefulness and value quite well over the years. Just note that Canon has modernized their ETTL (II) protocol over time and there are incompatibilities sometimes. In many (but not all) cases firmware updates can be made.

Hello fransener,
thank you for this great site and nice reviews (keep them coming:)
I’m buying 3rd flash (already I have 2 sunpak 383 which are great),
and in the shorten list for the third are: Nissin Di622 Mark II (at 205$, it this getting expensive or what),
Metz mecablitz 50 AF-1 (for 230$) or Canon 430EX II (at 284$). 90% of the time I will use it off camera. Can u please give me some friendly advice because you worked with all tree of them (guess 48af1 and 50af1 are almost the same). Thank you in advance.
Best regards,
Max
Please recomend a Yongnou flash compatible with Canon SX30 IS
Thanks
I’am newbie on strobish,… would you help to to decided which one the best for master, and witch one for the slave..? (I use Canon 7D…)
Thanks
Nice site. This has made my choice a lot easier to make. I’m still kind of unsure If I should get the Canon 430ExII or the Nissin Di866. I’m really leaning towards the Nissin because of the Commander mode and I wanna get into off camera flash photography. I probably won’t buy anymore flashes though until I master it but I think it would be better to get one that can act as a master unit if I could under $400.
