#33. "RE: D700s"|
In response to Reply # 32
- AF-S NIKKOR 24-120mm f/4G ED VR (This is an upper end consumer lens, by the way, in my opinion.) - $1,300
- AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED - $590
- AF VR Zoom-NIKKOR 80-400mm f/4.5-5.6D ED - $1850
Now look at my example of a pro zoom FX glass set:
- AF-S NIKKOR 24-70mm f/2.8G ED - $1,890
- AF-S NIKKOR 70-200mm f/2.8G ED VR II - $2,400
- AF-S NIKKOR 200-400mm f/4G ED VR II - $7,000
So what's the difference.
Let's start with the 24-120mm, which is a darn good lens and f/4 throughout, which isn't too shabby, but it's still a full f/stop from f/2.8 lenses. The lens has some other great features such as VR, internal gocus motor, ED glass, nano coating, internal focusing, M/A Mode. As noted above, it's an upper end consumer lens. Compare it with the 24-70mm, and you'll see that this particular pro lens isn't VR, as it's an older lens, but it is a faster lens at f/2.8, and the 24-70mm could be considered just about the best zoom lens Nikon has ever produced optically. The build quality of the 24-70mm is superb with more rugged construction and professional-grade dust and moisture resistance.
The first thing you notice about the 70-300mm is that it has a longer reach than the 70-200mm, but take a look at the speed of the lens. It's f/4.5-f/5.6. The longer the focal length, the slower the lens, while the 70-200mm is f/2.8 throughout. At the low end that makes the 70-200mm at little more than 1 f/stop faster, and at the upper end, 2 f/stops faster. At the upper end, 2 full f/stops is a lot of difference, in my opinion. The 70-300mm does have 2 ED glass elements, but the 70-200mm has 7 ED glass elements and nano coating. The build quality and optical quality of the 70-200, far exceed the 70-300mm.
The important differences between the 80-400mm and the 200-400mm are to an extent the same as between 70-300mm and the 20-200mm; feature set, optical quality and build quality, and lens speed.
In fact, the difference between pro lenses and consumer lenses is generally just that, feature set, optical quality, build quality, and lens speed. One tip off, as to which is which, is price, as can be seen above. This isn't to say the consumer lenses are lousy. They're not. It's just that the lens quality of the pro lenses is better. They are characterized with better optics with less distortion, faster speed (apertures which open wider) with non-variable apertures, more features, though that is narrowing these days, and better and more rugged construction with the ability to resist dust and moisture intrusion.
I think that answers your question.
