Most welcome. Finally some people can see the real point of this thread. This thread is not about owning cz or feel good about it. It is not about similar lens of similar price, which I think most wont waste to own almost similar grade. It is not meant to be a pro or complex comparison of those review sites.
It is about learning together and sharing of actual result from a same situation of two different lenses with sizable price gap. It is probably simpler to understand and maybe useful for those who think of buying.
Whether worth buying, is entirely up to individual. Everyone make their own conclusion and decision based on own priority.
