Best 18-55 ever, for me. Having worked with 18-55 kit lenses from Nikon, Canon, Sony and Fujifilm, I rate this lens the best for a number of reasons. Its quality of construction and great damping of rings for just the right resistance and responsiveness immediately impressed me. It's a half-stop faster than the usual f/3.5 wide open, and a full stop faster f/4 at 55mm. Its sharpness rivals 35mm and 50mm prime lenses I've had from Nikon. For an APS-C lens it has pleasant enough, though not great bokeh (slight "onion" effect). The only discouraging thing about this lens is the high cost when purchased separately (still $699 retail). After a few hundred photos on my X-E2S I'm still pleasantly surprised at its results at all focal lengths and apertures. With this lens, I have no need to invest in primes.
Great lens, questionable origin I received the lens in great condition, packed with care, but when I unwrapped it I found that the serial number had been scratched at to the point of being illegible. This is the only sign of wear/damage on the lens, which leads me to believe it was an intentional alteration done by a previous owner. Kind of sketchy, and now I can’t resell the lens through any reputable store. This is my only issue though
Very nice lens for the price. Fujifilm 18-55mm 2.8-4 is a very nice kit lens that is much better than other kit lenses of the same focal length that I've used. It's solidly built and from the photos I took of my wife, son and granddaughter they came out sharp with no distortion in the edges like my 16-50mm lens has. It fairly light compared to my 18-135mm lens so it is good as a walking around lens which I intend to take with me at my neice's wedding this coming May so I can take my own pictures. I'm happy I bought this lens.
