Shortly after taking supply of the brand new Nikon Z MC 105mm f/2.8 VR S lens, I made a sequence of pictures to check its diffraction and bokeh traits utilizing the 45MP Nikon Z 7II digicam in a real-world state of affairs.
After manually focusing the lens, I locked focus and made a sequence of exposures. All exposures had been made in aperture precedence with the digicam set to ISO 64. The digicam was mounted on a ProMediaGear TR344L tripod with a Actually Proper Stuff BH-55 tripod head.
The 14-bit losslessly compressed NEFs had been processed in Seize One Professional 21, and the composite full-frame + full decision cropped pictures had been created in Adobe Photoshop CC 2021. The cropped views are roughly centered on the a part of the flower I centered on.
At regular focusing distances, the f-stop scale runs from f/2.8 to f/32 however with macro-capable lenses at very quick camera-to-subject distances, the utmost efficient f-stop will get smaller. On the distance I centered for on this sequence, the utmost efficient f-stop decreased (from f/2.8 to f/3.3) as did the minimal efficient f-stop (f/32 to f/40.)
The f/cease readings are from the digicam settings EXIF information.
I used to be pleasantly stunned to see how sharp the lens may render element all the way down to the efficient aperture of f/32, however even at a reasonable print dimension like 10×15, f/40 stays usable. Normally, lens decision actually begins to collapse by f/16 or f/22, even with different high-quality macro lenses I’ve used.
Bokeh, the transliteration of the Japanese language time period for the way a lens renders out of focus areas, stays clean all the best way all the way down to f/32 however begins to get a simply little uneven at minimal aperture. However what in order for you even larger depth of discipline? It’s essential to use a computational images method known as “focus stacking.”
