你的鏡頭有防抖，可以管4檔，但是如果你的手動速度超過了4檔的極限，不清楚還是可能的。如果原來沒有對好焦，不清楚是可能的。
試試 1. 用光圈f/5.6或 f/8，用三腳架，用快門線，不用防抖功能。如果想整個花都照清楚，減小光圈。
2. 如果不用三腳架，用防抖功能，但是多拍幾張，用同樣的光圈速度或變光圈速度。這樣就不會錯過機會了。
3. 可以設置成按一下快門連拍3張或5張同樣的景，-1EV, EV, +1EV. 或 -2， -1， 0， +1，+2 EV，拍後軟件弄成HDR（high dynamic range)。
你的D500的快門壽命可能是20萬。deepseek 說用人用到超過40萬，所以不要怕多拍。
我問deepseek的問題和它的回答：
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.
