I'm a member of a camera gear buying and selling page on Facebook, and today a member uploaded a huge Canon collection for sale. Looking through the gear, there was a couple of cheapish Canon speedlites. This got me thinking..
It doesn't seem to be common knowledge that you can use any brand of flash with any camera! Obviously the ttl mode won't work, but you'll still be able to use it in manual mode!
Nikon speedlites are used by alot of Canon shooters because of their superior performance!
Learn how to use speedlites in manual mode and you'll open yourself up to a ton of buying opportunities.
