CUSTOMER FEEDBACK :
It's definitely a great lens, a lens that is extremely affordable, approx 80USD. It is outstanding in low light and again, it is CHEAP. This lens has received epic reviews from every photographer. Its built quality and its pictures are perplexingly amazing. My versatility requirement has been met at every angle. This lens is incredibly versatile, good zoom range, great for low lighting shots. The 28mm is decent enough for landscape. The other end at 75mm is quite good for portraits or just typical zoom images.
