After using the Sigma for so long, I am still impressed by its performance although I have notice some of its evident weakeness especially at 200mm as it becomes very soft when the aperture is opened all the way to f/2.8 (closing it down to f/4.5 seems to fix the problem).
Here are some shoots from it
I also realized that doing post-process sharpening on pictures taken from Fujifilm S5 pro where the image setting has been adjusted down to 6MP or “m” on the camera instead of “L” are a lot better then post-process sharpening on 12MP or “L” JPEGs. As the sharpening does not introduce a lot sharpening artifacts, in fact it’s almost nil.
So until then pleasant dreams~!
