I’m doing night shots with my newly acquired Nikon AF-S NIKKOR 50mm f/1.4G Lens on my D750. Trying to get the lights to Star I wanted to go high on my f-stop readings but my camera will not let me go tighter than f-16. I can get smaller apetures with other lenses. Is it me, my lens or camera blocking smaller apetures with this lens?
I couldn’t delete my question but found my answer. f-16 is the minimum aperture for this lens. I need to read the fine print. Maybe this will help someone else.
If you were to look up the specs on your lens:
Minimum Aperture f/16
--
You may find f8 will work for the "stars". Experiment.
I can post an example with your permission.
You could also try a Star filter.
According to Nikon's specifications, the minimum aperture on that lens is f/16- there is no f/22 in that lens' formula or aperture system. Perhaps the designer found that smaller apertures would yield too much diffraction or there was some other engineering limitation?
There are many less that do not stop down further than f/16. In the olden days, the f/stops were engraved on the lens barrel and were manually set. The electronics and the accompanying readout in the viewfinder or on the LCD screen in your camera will not show anything beyond f/16 because the lens does not have that as a minimum aperture.
f/16 at long exposures MAY still create the star effect on point light sources in the image- that depends on the actual configuration or shape of the diaphragm blades. If that does no work, you can use a star-effect filter. These are clear filters with black mesh (netting) sandwiched into the filter. There are others with fine grid lines etched into the glass. They come in various strengths. Black tulle (very fine netting) can be found in fabric stores- stretched over a lens shade- it too will create star patterns. I prefer the tulle fabric method in that it does not tend to defuse the entire image - some of the filters introduce some softness.
F/stops used to be "stops". The engineer would figure out the math, and you matched the right bump with the right dent.
Most bokeh is shaped by aperture. Look close- a 5 blade makes stop signs, 6 blades make hexagons, my 13 blader makes circles.
In the olde dayes, we'd get black construction paper, put the lens on top, and mark it. Cut around it so it just fits in the lens. Make a bunch. Doing a wedding- cut a full heart out of the middle. You could try a big fat star. I liked a cateye thing- it gave me sharp centers, with diminishing IQ on the sides.
Good for portraits. YMMV. Experiment. Practice.

As others have mentioned, your lens only stops down to F16. Besides, loss of sharpness due to diffraction may not be to your liking. These were done with a Nikkor 80-200 F2.8 AF-D, which has a 9 blade aperture.The first was at F10, the second at F6.3. You don't need to go to the smallest aperture.

From what I have seen over the years, lenses seem to have a maximum 7 stop range from widest to smallest aperture. I don't know why.
It's Nikon lens. If you find a Nikon lens with f/1.4 that has f/22 let me know. I meant in the F mount.

Set to Auto ISO, Aperture priority at f16.
Minolta has them from 1.4 -22. Sony does as well (which makes sense).
Put it down to .... engineering laziness and market complacency on the part of Nikon.
It's very doable....

Buy a “star filter” so you can use wider apertures...

Why do you want to photograph stars with small aperture? It makes no sense.
