I am selling Mamiya Macro A 120mm lens mint condition!
Manual focus lens with superb resolution, good corners (this is where a landscape photographer like me, who loves sharp foregrounds needs good results), centre best at f8. The best Mamiya/Phase One lens I've ever used. All four corners and the centre are excellent. I use it more for landscapes than macro, but it is also a magnificent macro lens. Performed well wide open at f4. Highly recommended lens 10/10.
Brand new cost HKD 7,500 (http://www.bhphotovideo.com/c/product/539570-REG/Mamiya_210_614_Macro_120mm_f_4_Manual.html)
Please note that we would need to meet at my office in Shau Kei Wan on weekdays between office hour (9:30 am-6: 30pm).
