Very sharp images from infinite to 0.38m and pleasing bokeh of macro shots. Wide range of usable aperture values. Auto focus speed is reasonably fast especially for a macro lens with large distance to go between both ends.
缺點:
Many reviewers may overlook this point. While in AFS mode, real-time manual override cannot make to the lens until HSM stops after auto focus completed and camera confirmed in focus. When auto focus fails, shutter locked no matter subsequent focus is made using manual focus override. In AFC mode, manual override auto focus cannot achieve too because HSM works continuously and reset any focus made manually back to its calculated value.
評價:
With reviews from different sources, I am misled manual override can apply to the lens at any time. I think this macro lens can auto focus to the nearest point close to the exact focus, then I can override it quickly and fine tune to the final focus at any time like AFS Nikkors. It is very important for insect photo taking as everything is dynamic. Unluckily, it can’t and I can only switch to full time manual focus or see if I have luck to get the focus under this HSM auto focus. Luckily, I still have a sharp prime lens with affordable price ($47xx from shop@dcfever).
1) Focus not that bad, actually really close to 100mm macro
2) Color is great
3) 150mm is useful for take flower and bugs
4) IF
5) Have tripod ring mount
缺點:
1) Also... easy paint off
2) Focus have little bit noisy
3) If have OS, must be perfect
