sharp good color tone

none

I have contax 60mm f2,8, leica 100mm f2.8, zeiss100mm f2 and Tamron 90mm f2.8 all of them are super for marco photos also the Minolta 100mm f2.8 is one of my marco lens collections,it's quality is between leica and Zeiss 100mm Marco lens ,the price is 1/3 to half of them for me it's price is very reasonable .
( most of time I use manual focus for marco photos but who will take marco photos by auto focus)

非常稅利

對焦慢, 甚至對唔到

由 50 macro 轉用 100 maco, 稅利度不減, 但感覺十分難用~~
