i have a 105mm 2.8 macro. the focusing distance is very different from 105mm 2.5. have you check the focusing distance of mark 2 sigma hsm 70- 200mm f2.8 macro ?
i might be buying a 80-200 locally or fly to HK to buy 70-200 if the price is much lower. anyone knows where to buy nikon in HK?
Initially, i wanted to get a 85mm 1.4. but it will distort for head and shoulder shot(shoot too close).
in terms of distortion if any, is 2xTC on 85mm same as "170mm"? or distortion is purely because of close shooting distance.
