主要是想用在我的x-e1上,35已经有canon的,performance真的还是不错的,但是在crop上想进一个广一点的,街 ...
fuji-x-e1是好选择!
广角镜头对设计工艺要求很高,以往的广角多是 retrofocus 的设计,而这种设计本身就有限制。
广角镜头曲面及变形不说,光谱在镜片组的折射后焦点不聚集,产生chromatic aberration,降低锐利度及对比是主要的问题。
以前的(日系)镜头厂采用含thorium的放射性元素作为镜片原料,时经几十年后,thorium镜片发黄,虽可用紫外线可漂白,毕竟很麻烦。
德系有采用石英,好比Leica 35毫米的‘八枚玉’,三千美元。。。晕
目前的镜头采用非球面+LD镜片+改良设计,锐利绝对提高了,其他的就得看个人偏好了。
总之广角镜不好选呀,price--to-performance ratio很难在这里体现。
下面是我个人的简单选择,供参考
Fuji X-E1, 35mm f1.4 <== the most safe bet, perhaps
Voigtländer 21mm f/4 Color-Skopar <== leica performance, if not better, for 1/4 the leica cost
Yashica ML 28/2.8 <== a good copy for about $100 or under, it's definitely a keeper
Carl Zeiss Jena Flektogon 2.8/35 <== cheap, can be quite good in experienced hands
Vivitar 24mm f2.5 <== under $100, good to usable,
Konica Hexanons 21/4 <== overpriced in general
Yashica ML 24/2.8 <== very good performer, but overpriced, grab it if under $250
Tokina 3.5/17 <== seems usealbe, no experience
Canon FD 20mm <== FD are mostly good performers, just that, there's nothing special about it, also beware about the thorium elements
