i just asked this question but you told be about the camera
i was wondering what is the diffrence between the nikon 18-200mm lens and the 70-200 mm lens why is the 70-200 mm lens wayyy more expensive does it zoom in farther? or not?
Answer
It's more expensive for a couple of reasons:
1. It's an FX lens. Compared to the 70-200mm, the glass elements in the 18-200mm are physically smaller. Smaller lens elements are easier to make. The tradeoff is that you can't really use them on an FX camera. The 70-200mm lens was designed to work on both.
2.It has a wider maximum aperture, a constant f/2.8 across its entire zoom range, compared to a variable f/3.5-5.6 on the 18-200mm. Lenses with wide maximum apertures need larger glass elements. Are we detecting a pattern here? :)
3. It's a professional lens. It uses five extra-low dispersion glass elements, which are very difficult to make, it has internal focusing, three autofocus lock buttons, nine aperture blades for neutral bokeh (and 18-pointed sunstars!), and frankly the thing is built like a tank. Every nice, special, amazing feature you can pack into a lens like this, it's got.
The bottom line has to be whether these extras are worth it to you. You almost always get what you pay for with lenses. If one costs twice as much as the next, there's a reason. Only you can decide whether it's a good reason.
(And no, they both zoom to a maximum of 200mm.)
Hope this helps!

Nikon lens slr camera?

What's a decent lens for a slr camera? Is a 70-300mm good for sporting events?
Answer
Apart from telezoom reach, action events need a fast (f/2.8) lens, all the vibration reduction (VR) you can get, as well as fast and reliable AF. Nikon 's 70-300 mm only has f/5.6 at the 300 mm end, which may just be adequate under the brightest of circumstances, but will let you down under less favourable lighting conditions.
However, a 300 mm f/2.8 prime lens will set you back a cool US$ 5,500, so you may want to have a look at the AF-S 70-200 mm f/2.8, which is just over $2,000. A somewhat older, second-hand 80 (not 70mm) -200 mm version in good nick can usually be found for less than $ 1,000 , although you'll lose some of the AF-speed compared to the latest version.
