Sorry,your right I made a mistake.

Hi, I'm stuck with a heavy,long lens. I recently got interested macro photography which is great fun for me. So I bought a Sigma 105mm macro lens which I like, but I just got a Savage adjustable tube to boost my macro lens. Trouble is the set seems a bit heavy and long. The lens weighs about 3 pounds and the tube is about 3/4 pound. Oh and I'm using a Nikon d7100. I'm still a rookie at photography and need as much advice as I can get. Thanks for your time.
