Customer Reviews

Good lens, sharp picture, but it's not nice with body color & material
Good lens, sharp picture, but it's not nice with body color & material (the newest model).

Pretty darn good, especially at this price!
This lens in pretty good, there's no AF motor in the lens so autofocusing can be fairly loud (on my D90 anyway). Photos are very sharp, even at 300mm. Crank up your ISO and keep your shutter fast to minimize blurring since there's no vibration reduction. I was able to pull off some extremely sharp shots in late afternoon sun at 300mm while hand holding. Use a tripod or monopod whenever you can. It's not as good at macro because in order to turn the macro switch on the lens on, you have to be between 200 and 300mm, then to turn it off you have to switch your camera to manual focus turn the focus ring to infinity then you can switch it back to normal, which can be a pain if you're in a hurry. You also have to be a good five feet away for things to be in focus (and fit in the frame, a leaf almost fills the frame while I'm standing up straight and holding the camera at eye level). For this price I don't think this lens can be beaten for quality or price.

Good Value - for the occasional user.
Good value for the money; just don't expect the features or ruggedness of an expensive Nikon macro. What's primarily lacking is a tripod mount and/or VR. The occasional user who owns a sturdy tripod and a remote release can work around the missing features but some care is required inasmuch as this is a loooong lens at full extension. Optical characteristics are very good. Mechanicals are acceptable.
