请教：机身D800，已有24-702.8，70-2002.8，被大家所拍的蔡司所迷，想入个蔡司，犹豫不决，请问哪个合适，21、35还是100？

以后都得有，不过看你主要拍什么为主了，风景多就21，我建议先上35，用途比较广，我入的顺序是35-100-21！

谢谢。我喜欢风景，但是又喜欢1.4的光圈。要是钱多，就全拿下了！

那上35吧，风光、人像、小品都行，还有你喜欢那1.4，免得纠结！入了蔡司门，那手感是原厂镜头不能比的，你会陆续买进的，100也非常好，用途也很广，这三个头素质都不错！

谢谢！

21和35都必须入，2枚迪斯塔根结构的经典头，第一枚的话建议35。

楼主二个头都没法喂饱D800的36M机身，若买35先，就与你的2470重叠，不合适；可以这样来：
方案1：保留二变焦，进菜21或18；保证焦段全。
方案2：进35和21，同时出掉2470，也可基本覆盖全焦段。
我本人倾向方案2；成本不高，也可考虑二手货，更关键是35拍人像，小品绝对胜过2470；再个35最好不要进菜头，适马35a比它便宜但更锐，这可是著名的法国DxO实验室推荐给D800E的最佳风光镜头，盖过菜35好多，菜35紫边太严重，锐度一般，我都想再进适马35a和50a......

Best wide-angle primes for landscapes
Of the wide-angle lenses analyzed the best performing models are unsurprisingly those closest to the 50-85mm focal lengths. Models with shorter focal lengths are much more difficult to correct for the various aberrations that inevitably occur at such extremes.

The Art series Sigma 35mm f1.4 continues to perform well on the Nikon D800E and not only is it the best corrected but it has the highest peak sharpness. In fairness, though, the 24mm focal length is arguably the most popular wide-angle model, and it’s well suited for landscapes.

非常感谢您的回复！

谢谢！

关键看楼主平时喜欢或者经常拍摄的题材，都是好头！
