Excerpt: I tend to rate items in relation to their cost. It would be silly to expect this lens to be in the same category as one 10 times the price; yet no professional lens is 10 times the value of a good albeit slower lens such as this.
Excerpt: I use this lens for traveling to get a little extra reach. It is small and very light.....great for traveling. It is not super sharp, but more than adequate for smaller prints or internet photos. although I think you could get a very nice 8x10 or 11x14 inch prints.
Summary: For the price, a miraculously good lens. I tested this lens on my Panasonic GX-7. Indoors, at short ranges (up to 15 yards or so) all shots were clean and ranged from very sharp to impressively sharp at all focal lengths.
Summary: This is a cheap lens, with a wide zoom range. It's slow -- but it doesn't have most of the other problems expected in such lenses. I find it remarkably sharp and crisp. (I used on an EPL-2 and now an OM-D EM-5).
Summary: I am an amateur, so take this review from that perspective. A more capable photographer might get different results, but this lens is priced for the amateur, so here goes. This is a good-priced and a lightweight lens.
