>>4017506I know this was 14 days ago but you don't need a special flash for macro, just one that's big enough to not get blocked by the lens. I use 2 Godox 350 standing next to the subject and one of the Godox remote triggers, I think an X1. I got them used from ebay and it came out to about $100. Another thing is if you are using extension tubes, line the inside of the tube with black telescope flocking material. Reflections coming from the inside of the tubes can create a lot of haze.
