| thephotohiker | Great Lightweight Lens | | 
Voted 5/5 | I recently purchased a Nikon D80 kit which included the Nikon 18-135mm AF-S DX lens. To keep the lens lightweight and be able to sell it at a competitive price (inexpensive), Nikon used acrylic (plastic) lens elements in its design. Now don’t get me wrong, I’m all for lightweight, especially when hiking/climbing. But one should realize there is a degradation of picture quality when using lenses which are not all glass. Fortunately the degradation in quality with this lens is acceptable in most situations.
I verified the degradation by taking pictures of the an object using the Nikon 18-135mm AF-S DX lens then one of my “older” all-glass lenses at the same focal length. When I compared the two resulting pictures at high magnification, I could easily see that the all-glass lens gave a higher quality result.
That being said, one of the reasons I purchased the D80 kit was so I could reduce the weight I carry while hiking/climbing. I knew I would be giving up some picture quality by using a partially plastic lens, but I’m willing to live with it. The degradation is so slight (when compared to all-glass) that it’s insignificant in most cases – macro photography being the exception.
It’s a good lens, and I’d buy it again.
