You are bidding on a pre-owned Canon EF 35mm f/1.4L USM Lens. This lens
is in excellent condition, it has been very well kept. The camera takes
excellent photos. When I take the lens off of the camera and look into the
light I can see a microscopic piece of dust (not mold). This does not affect
the way pictures come out, however I have to list this. The auction will

Now it’s getting serious guys! The very reliable Japanese website Nikkei (
Click here) reports that Sony plans to buy a 20-30% stake of Olympus.
Techradar says that “The capital and business alliance would be mainly
aimed at bringing together Sony’s strength in imaging sensor technology
with Olympus’ expertise in endoscopes and other medical equipment.” Only
one week ago Olympus Japan announced new digital microscopes with Sony’s
HDR sensor. |

你这个显微镜呢，类似上面这个。 叫体视显微镜，看东西有立体感。一般用来做解剖
什么的，比如ZEBRAFISH,小苍蝇，WORM什么的。看1微米的东西，没戏。
分辨率这个东西，要从镜头开始算，照相机再牛，也没有用。我一般是用这个公式算光
学分辨率：0.61 × 波长 除以 NA.
波长就用平均值550纳米吧（就是0.55微米）
你那个物镜NA猜个在0.1左右吧（说不定还更小）。
（NA - NUMERICAL APERTURE)
0.61 * 0.55 / 0.1 约等于 3.355 微米。 这是光学原理决定了，你最多最多只能看见
3－4微米的细节。
但是我不知道你的物镜的NA是多少，假如是0.01呢，那就更惨了 －－－ 细节只能在33
.55微米了。 |

It was the famous photojournalist Robert Capa who once said "If your
photographs aren’t good enough, you’re not close enough.” He was talking
about getting in amongst the action. If you feel like your images aren’t ‘
popping’, take a step or two closer to your subject. Fill the frame with
your subject and see how much better your photo will look without so much
wasted space. The closer you are to the subject, the better you can see
their facial expressions too.

@方舟子 :说一种农药低毒无害是指施用剂量而言的，而不是指当饮食往嘴里灌。

千万！不要！刮！ 你的肛毛！！！！
最近我犯下了人生中最大的一个错误！！！！
现在把经验告诉大家，希望大家能从中吸取教训！！！
这一切都要从我拉便便的问题开始说起！！！
不，你想错了，实际上，我并没有便秘！！！
只是在技术上的排便问题而已！！
我的肛毛太长太浓密了，每次拉便便总有一些沾在毛上面！！！
这些残便粘的很牢，这让我非常不爽！！！！！！
我必须用纸清理我的肛毛！！！
但这是个技术活！！！
因为看不见我的屁屁，清理肛毛的时候经常会把屁屁其他地方弄脏！！
还有一个方法是用很多纸把整个屁股仔细擦一遍！！！！
这样做的后果是纸用得太多我家马桶经常会被厕纸堵住！！！！
这个问题困扰我很久！！！！！
经过深思熟虑以后，我想到了一个好点子！！！！
这是老子的屁股老子的肛毛！！！我的地盘我做主！！！！
为什么不把肛毛刮了呢????
这样我的大便不就可以流畅排放了吗！！！！
我脑子里不禁浮现出金黄色的啤酒从酒桶里潺潺流出的美丽景象！！！！！
但后来的事实证明，这是一个非常错误的傻B想法！！！
那天晚上，我坐在毛巾上，开始用廉价的一次性剃刀刮我的肛毛！！！！
