Lens Construction
MTF Chart
All macro lenses (with a few exceptions, like the compensating 55mm f3.5 Micro Nikkor of long ago) stop down as they are focused closer. I think they were bigger and heavier than a 55 f3.5. But they were designed for manual exposure calculations before TTL metering.
Think of the amount of light that would reach you looking down a long hallway with a window at one end. If you could “focus closer” by extending the hallway with the same window, there would be less light reaching you. NIkon is really good at showing this effect in the display on its cameras.
And I don’t think this is altered by internal focus.
Probably won’t be seen by the OP, but for anyone else who experiences the above question/phenomenon…
the f/stop limitations pertain to the distance the lens is from the subject. f/2.8 is possible only at certain focal distances. The lens adjusts the f/stop based on the distance.
My new 105mm VR macro F stop odd behavior, defective?
In A or M mode, the F stop keeps changing by itself as the lens auto focus on shutter half press. Another problem is, I cannot set aperture to F2.8 most of the time. As I turn the main dial, aperture just stuck at F3, F3.2, F3.3 or F4 and refuse to go farther towards F2.8.
