I have a Nikon D3300 camera and I decided to take a step forward: buy an external flash. As I have a very tight budget, I would opt for the SB-100 "alternative" – Meike MK-910.
My question is whether the flash and the body are compatible in two ways;
a) is ttl communication reliable?
b) how to use the flash outside the camera (as a slave). Does it work directly or do I have to buy a transmitter / receiver?
