冬意浓~

前一阵子还是"满城竟是红叶景",短短两周时间,叶子都掉光了,现在看只剩下枯枯的树杈,好不凄凉~天气也逐渐冷了下来,前天居然还飘了几片雪...冬意渐渐接近了~

因为准备上学,所以没带家伙.这是在车站用手机照的...
像这样还挂着叶子的树越来越少喽~

The Biggest Camera Lens in the World Ever

世界上最大的镜头是什么?

是Sigma 200-500 f2.8?




不是!这也太小了。















那EF 1200 f5.6如何？














不好意思，还是小。


















对了，Nikkor 1200-1700mm f/5.6-8 P IF ED够大了吧！？

















。。。。仍然有点小。



















想起来了，难道说是中画幅的ZEISS Apo Sonnar T* 1700 f4?


















这个家伙够大，但。。。。。






还不是。




















其实，这些镜头虽然已经不小了（1700f4有256Kg），而且价格不菲（EF1200f5.6可以买两辆悍马）。。。但是，你有没有听说过5200mm的相机镜头呢？
没错，没有写错，是5200mm
而且是f14!用5200除以14，光圈直径达到了37.1cm!










这就是佳能1965年生产的FD5200 f14 Ultra-Telephoto Mirror Lens


最小对焦距离120M！OTZ 不知道给它装上近摄接圈会是什么效果？XD
总重100kg(without stand)，要想用它估计还得买一台吊车。
总长1.89m
覆盖角度不到一度：36'
可以拍摄18-36英里以外的物体
不过这个庞然大物的光圈是真正意义上的恒定，完全靠ND镜来控制曝光

镜头结构


前一段时间，这个怪兽还在ebay网上出现过，号称是全球仅剩3颗中的一颗，起拍价55000美元，不过貌似没卖出去罢了。。。

单反必修课 相机镜头清洁

对数码相机来说,最脆弱的地方莫过于镜头了.无论你的机身是铝镁合金还是工程塑料,镜头永远是光学玻璃制成的.更何况高档镜头表面还有一层特殊的镀膜,一旦磨损,势必会影响到相机成像质量.那么如何清洁镜头,同时保护镜头表面不被损伤,在此讲一点个人经验以供参考.

No.1 吹气球(皮老虎)



这玩艺基本属于相机的影子,永远不要离开摄影包。 选购的时候尽可能买高级的产品。 有些劣质吹气球不能保证一个孔只进气，一个孔只出气，这样就很容易把镜头表面的灰尘倒吸进来污染皮球内腔。更可怕的是，还有些劣质产品在橡胶老化后内部会有颗粒脱落，会随气流吹出。那时你的镜头清洁工具就变成了镜头杀手！。。。

No.2 毛刷



选择刷毛柔软的产品。如果镜头不是很脏，只有少量浮沉的话，用毛刷很容易将浮沉除去。要注意的是毛刷本身也很容易吸附灰尘，即便保管很好，也避免不了窝藏上次镜头上刷下来的灰尘，容易搞坏镜头。是用毛刷时，应用刷子轻轻地把镜头上的灰尘扫一下，而不是大把大把的真刷。扫完后用气球吹掉最好。。。

No.3 镜头笔




十分好用的工具，强烈建议购买。一般在镜头很脏的时候用。好的笔头都是用极细极软的细毛做成，而且上面附有特殊碳粉，可以吸附油脂，比如指纹就可以轻松除去。清洁的时候由内向外一圈一圈的擦，切不可像扫地似的一下一下，这样会使碳粉脱落而影响成像质量（虽然很细微）。。。

说明一下，我觉得镜头笔基本属于终极工具了，当然还有两种经典的工具镜头纸和溶剂（乙醚与无水酒精）也不错，但是比较麻烦，比如镜头纸必须撕开用毛边，而溶剂用的是超级易挥发的液体，放久了比例肯定不对，得经常配，很是费事。。。

最后，说一下清洁镜头绝对忌讳用嘴吹，或者哈气。。。因为唾液中的酸性成分很可能对镀膜有破坏作用，要知道很多牛头与狗头之间的差距就在薄薄的一层膜上面。。。
