優點:
-sharp sharp sharp! especially at the tele end
-VR effective (the VR switches are well positioned to use by your thumb, and it takes a hard click to switch between, which makes it difficult to be swiched accidentally)
-silent focusing
- Zooming is smooth
-well built for a plastic lens
-light weight
- Low distortion at 18
- the hood looks fabulous
- lens soft pouch is included unlike some other old models
缺點:
-the plastic mount will wear very quickly if you change lens frequently
-67mm filter size, and the lens is a bit fat, sacrificed for the built-in motor
-yesyes, they are right, focusing is comparatively slow for an AF-S
-no distance scale (but that's good, save space)
- Stray light a bit too much
評價:
The real name of it is: DX SWM VR ED IF Aspherical....(Long name indicates its a modern lens with nikon's all technology thrown in, or you may call it marketing HYPE)
The range is very useful, a very good walk around lens(especially for TRAVELing)
Image quality is very good at the wide end, good at the normal focal length and nearly excellent at the tele end.
4XX gram (weight) is just right for a zoom and well balanced at the D90 even without batt. grip.
Distortion is very little (comparatively) (think about its range 18-105, some prime lens produce more distortion than it does!)
The only drawback will be the small aperture at 105 (that's why it has to be a VR)
Some say the zoom ring is poor positioned, well, yes its a nikon's new style, with focus ring at the back. but i find no problem at all becos the zoom ring is very wide and the focus ring is very narrow. It also uses different material for the 2, so i never get confused
People always comment on lens' colour reproduction. I doubt their accuracy on that, becos we all see the world differently, some people like warm colours, some don't. Also its always the responsibility of your camera to tune tones when set at Auto, otherwise its YOUR responsibility to set it right. For this lens paired with my new D90, I see no big issue on colour reproduction, that's all I can comment on.
