I buy this lens to use with my D100, I have 20 2.8, 28 1.4, 24-50, 50 1.4, 70-180 micro (All Nikon) to used before but it's unconvenient to change a lens when you need other focal length and when you change a lens a dust may come in to your camera's CCD.

AF-S is really fast and you can shift a manual focus all time. Lens is sharp, at 18 or 20 of this lens have more distortion than 20 2.8 but it's sharpest than 20 and it's less of chromatic abberation. compare with 50 1.4 sometime it's sharpest than my 50 1.4 (AF-D), but fast lens is easy to use in low light situation. this lens can beat my 24-50 but cannot beat my 28 1.4 in picture quality that it have 5 times or more in pricing.

All of cosmetic is great I love Nikon design. It's not like a cheap 18-55DX or EF-S 18-55, it's build solid.

Closet focus is enough to talk some close-up shot, but with 70 mm you may get too close. Compare with my 70-180 micro, 18-70 get a lower magnification than 70-180 micro in a same close-up shot.

Buy it!! if you need real all-around lens but not have more budget to get 18-200VR. SHARP, FAST, CHEAP, CONVENIENT as your want. I recommend!!

This lens is ultra sharp at all lengths. I am a professional portrait photographer and this is a terrific all-around lens. I used to have to buy three lenses to give me what this one lens does now. With the cost at about $250 on Ebay, This lens simply cannot be beat.

I am a professional wedding photographer. Each year I shoot 35-40 weddings; taking about 800 images at each wedding. I use this lens 90% of the time during the day. It's versatile and great for groups as well as candids. It's sharp and I love the accuracy of the auto focus. Highly recommended.

I must say, this lens rocks. It's very contrasty and color redention is great. And very sharp, too. Many zoom lenses don't perform well at their longest focal length, especially at the widest aperture. But even at 70mm and f/4.5, it can still hang with the big boys. There's a little bit of light falloff in the corners at 18mm wide open. However, that's no show stopper because it's not bad and rarely will you need a wide open aperture at that focal length. There's some barrel distortion at 18mm, but will not be noticable in most shots. In the real world we don't take pictures of pieces of paper with grid lines, do we? The f/3.5-4.5 is a little faster than your typical f/4-5.6 zooms. So you get slightly faster shutter speeds and better autofocus performance in low light. And the autofocus is fast and accurate, especially for a lens in this price range. The focus ring has a nice smooth damped feeling when focusing manually. But the focus ring is in the back and zoom ring in the front, which takes some getting used to. Build quality is great for a lens of this price point. And there's even a rubber seal on the lens mount-I've never had a lens with a seal. The lens hood was hard to remove and install, but if you grab it by the sides and not top and bottom, it makes it easier. But I still found it a little tight, so I sanded the plastic stops on the hood. You may want to do this to yours. The filter thread is 67mm-filters of this size are a bit pricey, but not nearly as bad as 77 or 82mm. Overall, the 18-70 is about the best bang for the buck that Nikon offers.
