This lens is a good starting point if you are interested in macro photography. RAYNOX DCR-250 is not a lens to attach directly to the camera body. You need a lens with a filter size 52-67mm.
I tried RAYNOX on the EF-S18-135mm f/ 3.5-5.6 9 IS kit lens (67mm) but I get a black vignette that covers half the photo. I have to say that the photos are very sharp.
The photos I posted here are my Raynox experiment with Canon EF50mm f/1.8 II lens (52mm). That lens was created for portraits. Gives a nice soft effect. With f-1.8 and Raynox, DOF is incredible. But it has to be very precise. These are photos of some kind of metal decoration with beads and a few photos of plants.
camera: Canon EOS 60D
Thanks, 
After this I bought a Canon EF-S 35mm f / 2.8 Macro IS STM, but I'm afraid I will damage it if I put Raynox, and it has only a 49 mm filter.
Some people use words, others use light to say what they feel.
