I own a d5100. I want to buy a wireless off-camera flash.
What I want is to:
1) I want to trigger it with an actual trigger, not with another flash (like the camera flash, etc)
2) I want it with ttl
3) If possible, that it could sync with rear-curtain too
Can you recoomend what is a "cheap" (I know that with those features it may not be) flash that can achieve this with the nikon d5100 if this is possible?
I don't understand a thing about flash, so I get really confused while searching online . I do want to learn, but I don't want to buy a flash that will hold me back later :/ .
Thank you in advance!
