It's capable of creating really good soap bubbles. A potential negative is its slowness, or strength of extra depth of field.
Another negative is visible onion rings.
What do you think?
Here it goes:

I think I like your results.
When I want "interesting" wide open rendering, sometimes it's nice to have the extra depth of field a slower lens gives.

Another thing, these photos are taken at 100mm. There are bubbles all the way from 28mm, but I think it's only at 100mm that the magnification is enough. Minimal focus distance is 0.56mm, as printed on the lens. And it stays the same through the zoom range. I'd like to try a macro ring or helicoid to get closer.
I don't have the correct adapter for this lens so had to jam the aperture lever with a small wooden stick to keep the aperture open. But I recommend getting an adapter that can control aperture.

Nice find! I never would have expected results like that from a cheap modern zoom. |

At 100mm, the lens is at f/5.6, so the bubbles are smaller as a result? Did you have to crop considerably to get those images or were you very close? _________________ Regards,

CFD is 56cm. At 100mm that will give large enough highlights. The lens doesn't have and aperture ring so you would get it just for wide open bubbles if not used on a Nikon body or with a capable adapter. _________________ pentaxian |

No they are uncropped fullframe shots at minimum focus distance. When zooming out and getting brighter f stops the rings still gets smaller because you can't focus any closer.
So this is as good as it gets when it comes to bubble size. With a Diaplan or Trioplan it's much easier to get bigger bubbles with f/2.8.
Here is a test from 100mm to 28mm at minimum focus distance:
#1 100mm
#2 85mm
#3 70mm
#4 50mm
#5 35mm
#6 28mm

When adding an extension and getting much closer, the tendency is for the bokeh to get more blurry or creamy, which changes the highlights. The f/5.6 may actually work in your favor when extending. _________________ Regards,

It's water drops after rain on a spruce tree. I don't know if there are versions of this lens or much about Nikon in general. But I think there are adapters that lets you control the aperture with an extra ring. like this :
https://www.ebay.com/itm/255103855692?hash=item3b655fec4c:g:F2YAAOSwiEdhGQHa
The lens has a spring loaded aperture lever that closes the blades when it's not mounted.
Yes extensions may change the bokeh, that still needs to be tested. |

Mine was about $12 with a F75 camera on a Swedish site. Maybe some luck involved. |

I saw a few copies for $50 or so at places like KEH and MPB, and there was one attached to a Nikon body that just sold on Shop Goodwill for $42 (lenses are often mislabled or under-specified there, and their search function is quite literal, so searching simply for "28-100" might turn up the most results). |
