nikon 105 mm micro lens, which is the best aperture or sharpest aperture for this lens
The Nikon 105mm micro (macro) lens, such as the Nikon AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED, is renowned for its sharpness and versatility, especially for close-up and macro photography. Like most lenses, its sharpness varies depending on the aperture used.
Sharpest Aperture for the Nikon 105mm Micro Lens:
Optimal Sharpness: This lens tends to be sharpest around f/5.6 to f/8. At these apertures, diffraction is minimal, and the lens achieves excellent edge-to-edge sharpness.
Wide Open (f/2.8): While the lens is still sharp at f/2.8, it may not be at its absolute peak sharpness, and there might be some slight softness in the corners. However, f/2.8 is great for achieving a shallow depth of field and isolating subjects.
Stopped Down (f/11 and beyond): As you stop down further (e.g., f/11, f/16, f/22), diffraction starts to reduce overall sharpness. However, these smaller apertures are often necessary in macro photography to achieve sufficient depth of field when working at very close focusing distances.
Practical Considerations:
For general macro work, f/8 is often the sweet spot, balancing sharpness and depth of field.
For portraits or non-macro work, f/4 to f/5.6 provides excellent sharpness with a pleasing background blur.
For maximum depth of field in macro photography, you may need to use f/11 or f/16, even though sharpness may slightly decrease due to diffraction.
Summary:
Best Sharpness: f/5.6 to f/8
Macro Work: f/8 to f/11 (depending on depth of field needs)
Portraits/General Use: f/4 to f/5.6
Always test your specific copy of the lens, as there can be slight variations between individual lenses.
现在外边零下2度摄氏，今天最高气温0度摄氏。最近气温忽高忽低，暖和的时候接近零上20度摄氏，但突然降温就像现在这样。今天早上听新闻说，我们这里医院住了很多很多的肺炎病人。估计多半是老年人，这种气温变化很容易感冒的，尤其现在电气费涨得很多，很多人天气稍微暖和一点就把暖气给关了，觉得只要水管子不冻就行，而到了下半夜气温骤降人很容易着凉的。穿得多，盖得厚都不如把暖气放暖和一点来得舒服，而且不容易着凉。
最近看到不少人感冒，也发现疫情后人们注意多了，昨天早上上班，进大门的时候看见一个人在门口拼命擤鼻子，脸都涨红了，估计到时候不想让人看到她流鼻涕吧，我赶紧进门，按了电梯发现她也进来了，而且也要乘电梯，我就边上走楼梯去了，可不想跟她一个电梯，虽然我戴口罩的。
下午来上班，我戴着口罩在电梯里，看见外边来了父母带着两个小孩，两个孩子蹦蹦跳跳想进电梯，我扶了一下要关的们，她们的爸爸看见我戴口罩呢，就挥挥手让我先走，等我走到楼上电梯开门了，我一看一家四口爬楼梯上来了。他们不想跟我乘一个电梯，看我戴口罩呢，不知是不是病了。这样是对的，防护到位了，少感染少受罪。
今年全球气候不大正常，不是狂风暴雨，就是大风暴雪，自然灾害比往年多而且厉害，对房子的毁坏也是空前的，而现在人工、材料都贵，所以大家的压力都很大。
我新买了一台车，昨天收到不知道哪儿，说要我买一个额外的保质，说如果坏了厂家现在不一定都保，以前我那台27年的车有段时间频繁收到这样的要求信，我都没搭理他们，等你用他们的时候就这不行那不行了，再说我这崭新的车保什么保。动不动还写着最后的提醒。都是广告。
现在赚钱的想着法儿的赚钱，等你用的时候想着法儿的不让你用。各种保险公司四处发传单，说多么多么便宜，多么多么想保啥就保啥。算了，就这么对付着吧。
现在的车越做越大越宽，而停车位却没有改变，所以停车在哪都不安全，我的后车门昨天发现被人磕了一下，一个圆圆的小印子，漆没事儿，估计是开门刮风的时候弄的，另外有些人开门就脚丫子踹一脚门人就出来了，这太不靠谱了，边上有车能不磕碰吗？然后扬长而去，我都看到过的，啥人都有。而且有时候边上很多空场就非得跟你挨着停，不知道那些人咋想的，有时候你停得远远的，等你出来一看，大空场的就你车边上一个大大的货车，简直不可思议。我怀疑有人是不是边上没车就不会停车呢？
赏花吧，相机拍的。

相机可用防抖镜头。旧的相机，防抖镜头都很便宜。照后用软件锐化，AfterShot,几年前$20买的，就可以。你看看
1. 和 2.
2. 是用AfterShot锐化的。
AfterShot. sharpen at 400 (可以从零调到400）:
1和2:
1.
2.
光圈是不是太大？景深有些浅。
速度是不是太慢？超过了防抖的极限？速度 应该是小于镜头焦距乘以2的倒数，见下面我的照片的例子。
用没用三角架或单脚架，如果用了，就应该turn off 防抖。用三脚架时也要用外接shutter release cable。
能告诉我这张照片的光圈，速度，ISO，镜头的焦距吗？我帮你看看。
eBay上有aftershot 3 pro （我现在用的）, $20 以下，买前问一下是否有装软件的code，如果没有，能不能退。
我这张照片, 光圈 f/32， 60 mm 镜头，速度= 1/160 秒 （小于 1/120 秒），最上面的贝壳角还有些模糊。
注，我可不是给卖方做广告的，不认识他、她。也不知可靠不可靠，买前一定要问问他。今晨刚查到的。

你的镜头有防抖，可以管4档，但是如果你的手动速度超过了4档的极限，不清楚还是可能的。如果原来没有对好焦，不清楚是可能的。
试试 1. 用光圈f/5.6或 f/8，用三脚架，用快门线，不用防抖功能。如果想整个花都照清楚，减小光圈。
2. 如果不用三脚架，用防抖功能，但是多拍几张，用同样的光圈速度或变光圈速度。这样就不会错过机会了。
3. 可以设置成按一下快门连拍3张或5张同样的景，-1EV, EV, +1EV. 或 -2， -1， 0， +1，+2 EV，拍后软件弄成HDR（high dynamic range)。
你的D500的快门寿命可能是20万。deepseek 说用人用到超过40万，所以不要怕多拍。
我问deepseek的问题和它的回答：
