p**o
发帖数: 3409 | 3 微距镜头像场比较平，当然这主要指的是小物距（比如半米内）的情形；
大物距情况下锐度不一定比得过普通镜头。
对焦行程中大概95%以上都用在半米内。远摄其实跑焦的风险较大。
光圈也不用太大。为保证景深，实拍时光圈一般都会缩到F11左右。
笼统地说，其实就是为近摄“优化”的。专镜专用。
拿来跟那些对无穷远物距优化的普通镜头来比，其实有点拿苹果比橘子的味道。 |

It is listed at $399. Add it to your cart and it should be reduced to $299!
They are also including a couple of free "extras."
That is an incredibly good price for a high quality 2.8 DX zoom. Note the "
DX"- it is APS-C only.
It comes with Sigma's 4 year extended USA warranty. The best price I have
seen before was $269 for a grey market lens on eBay.
DxO rated the Sigma 17-50 2.8 as the sharpest standard zoom on the D7100 24

一根钢条
经文: 「我以使你成为有快齿打粮的新器具。」（赛四十一15）
一条值五块钱的钢铁，如果作成蹄铁，可以卖十块钱；如果作成细针，可以卖
三百五十块钱；如果作成小刀，可以卖三万二千块钱；如果作成钟表上的发条，可以卖
二十五万块钱。但愿一根钢条，要值到这许多钱，必须经过多少锻炼啊！钢铁越经锻炼
、锤打、琢磨、越是值钱，这是人所共知的。
但愿这个譬喻能帮住我们缄默、安静、坚忍。受苦受得最多的人，常是结果结
得最多的人，因为我们的苦难能叫上帝得到荣耀，叫人得到祝福。 ──选
生命是很神秘的，生命确实是难以说明的，除非我们相信上帝正在为我们准备
场所和事工，那里需要经过高度锻炼的心灵来从事特殊的事工。

永不孤单
经文: 「你必不再称为『撇弃的』。」（以赛亚书六十二︰4）
「被抛弃」是多么凄惨的字！听起来像是一场悲剧。那是一种椎心刺骨的伤痛
，是一种痛彻心肺的哀绝，那是一种说不出来的心结纠缠。你曾被父母亲遗弃？你曾被
海誓山盟的情人甩掉？你曾被至友出卖？或是被你的亲人欺骗？这的确是令人哀痛欲绝
的不幸遭遇，但上帝若医治我们，这样的伤痛，随着时间的冲淡，还是可慢慢痊愈。
然而，若上帝抛弃你，那又是怎样的光景？请听耶稣在十字架上的呼求︰「上
帝哪，上帝哪，祢为什么抛弃我？」我们可曾饱受凌迟酷刑的折磨？可曾亲尝这种备极
羞辱的滋味？若有，求上帝为我们把这一切挪开，不要让这样的苦况重现。恶人常指着
受苦的圣人说︰「你的上帝已经抛弃你，所以祂使你吃苦受罪。」不，这完全错了。上
帝纯全的大爱要覆庇我们，要逼着仇敌收回他的话，至少要封住他的舌头。
相反地，上帝说︰「我喜悦你。」，我们的哭泣要转为欢欣。让那些以为被... 阅读全帖 |

A popular saying goes that Programmers are machines that turn caffeine into

And sure enough, ask a random programmer when they do their best work and
there’s a high chance they will admit to a lot of late nights. Some earlier

before the day’s craziness begins. Others like going to bed at 4am.
