Hello everyone. I have a Nikon D3100 and looking for a macro lens recommendation. I will be taking top down photography of mostly coral frags and small colonies. Coral placement is approximately 5 inches below the water level. I'm currently using the lens that came with the camera. I can get fairly good colony shots, but frag shots are just plan blurry no matter how I adjust the settings and lighting. I’m shooting under LED’s with T5 supplementation. I would say the light level is low to moderate. I'm also using the Avast top down porthole. Of course, cost is a factor. With that said, which lens would you recommend? Thanks a bunch!
