This is a beautiful lens. It's a must have for any photographer. The bokeh is simply mind blowing. Focuses very fast. Though the reach is 200mm the crop is very much usable for flying birds. Simply in love with this lens.
Fantastic Product! Was able to capture some amazing images even being just a beginner enthusiast. The sharpness of portraits is out of the world. The image stabilization works well. The focus and zoom rings are smooth and just right. Its taking me some time to focus on moving objects.
You need to develop your forearms and wrists though, just to handle the weight of the lens ;) This one now becomes my prized possession. The lens lived up to the expectations. Now it is up to me to meet my own expectations of capturing great images with this.
