Maintaining the same 50cm minimum focusing distance and optical construction of the previous, SL version, the lens has been redesigned with a smaller body. Additionally, by mounting the included close up lens, its closest focusing distance can be reduced down to 32cm, giving a magnification ratio of 1:1.8. Priced at ¥58,000 (~ US $645) for the Canon EF mount and ¥55,000 (~ US $610) for the Nikon Ai-S mount and Pentax KA mount, it will be available in Japan from early March 2010.
