50mm f1.2, f1.4 1/125
Nikkor 20mm AIS f/2.8, followed by 20mm AIS f/3.5 and 20mm AI f/4.
I have used all 3.
Best near and far field sharpness is the 20mm f/2.8, not as flare resistant as the f/3.5.
20mm f/3.5 near field is sharpness is very good but far field it sucks. Bokeh as can be seen is only so so.
20mm f/4, about the same performance as the f/3.5.
I use the 20mm f/3.5 as a wide angle lens and also a reversed macro with a PK13 extension ring. Near field it is sharp.
Here are some samples.
Used as a micro lens with PK13 extension ring

As a near field wide angle lens . Note the bokeh is not that pleasing.

Nice pics "bullterrier", especially the statue of the cobbler. Thanks for sharing.
Have a Nikon 105mm f2.8 AIS. A pretty sharp lens but only give 1:2 macro. Will need a PN-11 extension tube to get to 1:1. Are there other extension tubes that cost cheaper than a PN-11 and yet provide good IQ? Thanks
