This high-power, high-performance 4.3x telephoto zoom with VR image stabilization lens allows better hand-held telephoto shooting ED glass. High-power 4.3x Telephoto Zoom-Nikkor lens approximates the picture angle performance of a 105-450mm lens on 35mm SLR Two Nikon Extra-low Dispersion (ED) glass elements deliver superior optical performance for both digital and 35mm photography. ED glass minimizes chromatic aberrations, contributing to superb contrast and resolution performance Focus as close as 4.9 ft throughout entire zoom range A Silent Wave Motor (SWM) enables fast and quiet auto focusing, along with quick switching between auto focus and manual operation (M/A and M) Vibration Reduction, engineered specifically for each VR NIKKOR lens, enables handheld shooting at up to 4 shutter speeds slower than would otherwise be possible, assuring dramatically sharper still images and video capture Internal Focus (IF) provides fast and quiet auto focusing without changing the length of the lens, retaining subject-working distance through the focus range Non-rotating front element provides for convenient use of circular polarizing filters and the Nikon Wireless Close-Up Speedlight System A nine-blade rounded diaphragm opening makes out-of-focus elements appear more natural

Very good lens, but it has its peculiarities Jeffrey Bower After extensive research on many lens, I finally decided to plunk down $ 500 (at the time of this writing) to purchase this objective. It may not be the best on the market, which complements very well my Nikon DX 18-70mm. I was looking at the DX 18-200mm lens, but the price made me choose this (as was almost half the price and my two lenses can cover almost the entire range of 18-200mm). QUALITY / Weight: build quality is cheap and robust ... Chinky plastic is a little, but reduces the weight. My Nikon D200 has no problem handling the weight of the lens, but I have heard (unconfirmed) reports that this goal is a little heavy for lighter cameras (D80, D70, D40, etc). The ring connector is metal and has a rubber seal on the outside to provide less protection (lens mount) of the elements. Man you must keep that in mind, if you weight, quality and price, the price of this essential goal is to get the glass elements (all 17 elements of them) is expensive if you spend a lot of high-quality optics in a pipe. I am not surprised that the price of the 400 million price range would probably be better suited for this focusing plate / LENS ATTRIBUTES: Focus can be very fast ... sometimes. You can find the Max 300mm zoom range the lens has a hard time auto focus on an object. Sometimes he would focus fairly quickly, the 300 series, while at other times they can not concentrate at all. You can use this quirk by the issue around (manual) work and you can take the auto focus, it always works. I find this issue focus disappointing especially given the price of this goal. The quality of the bokeh (out of focus in the picture) is very nice and pleasant. The images are sharp, vignetting (dark areas on the corner of the images) is difficult to find and is usually a lens flare problems VIBRATION stabilization All I can say is that it works ... can be useful. It will not stop the slide guaranteed to you, is only intended to slow the rate at which the camera moves (vibration from holding). You can see the difference, with the former, you will see that the image (say 300 mm) really bounce, when virtual reality movie. It takes a second or two, but then the image smooths out, still reeling from it, but much slower. With VR enabled, you can go 2-3 (four times), let down, what you normally do when his hand in celebration. THE "shock" TEST: I have not "crash tested" my lens yet (that has fallen down) but I have heard (again unconfirmed reports here) that keeps a pretty good fall ... although I never recommend tests. IMPORTANT NOTE: The range of 70-300mm should be noted: Although the lens is that it is a 70-300mm zoom, this lens is designed for a 35mm camera or full frame CCD / CMOS digital camera, all (or at least most) Nikon DSLR (D200, D80, etc.) are not full-frame sensors. There are about a factor of 1.5 x full-frame sensor (due to smaller sensor). What does this mean? Well, it's simple, because this is a 35mm lens and a DX lens is not (ie built to account for the 1.5x factor in most digital Nikon) you must apply the 1.5x conversion. This means that the Nikon 70-300mm on a Nikon DSLR, an apparent zoom equivalent to a 105-450mm lens. I do not mind this apparent zoom and the sticker that projects like the lens of the sensor is larger than the sensor area to remove. In short, those parts of the image spill over the sensor, since this lens was made into a film projection sensor/35mm full-frame. CONCLUSION: Advantages: Nice Bokeh Fast Auto-Focus (when working properly) Vignetting is minimal image stabilization (VR) Flare is minimal factor of 15x (105-450mm).
