Here too. Foggy, dim, moist. Despite that I suspect I could find something interesting to shoot, but I´m lacking the motivation to set a foot outside. Mr. Green

Nikon AIS 20mm f/3.5
Vivitar 19mm f/3.8, (people said it is actually 20mm f/3.8 Cosina)
Both are small in size. Will be fun to compare, if the Vivitar can compare.

Not all Silver and Black early versions are Sonnars, but easy to spot from the rear. The Sonnar has a much narrower rear element than the Gauss.

A bit strange that a lens with a newer optical scheme has older mount screws.

Probably been worked on.
There are much stranger things with nikon lenses and their serial number ranges.
It would make sense for Nikon repair service to replace the old slot flat head type with the cross-points- just from an ease of installation viewpoint.

You will find that the Nikon is quite a bit better.

I have a screwdriver filed to the exact size of Nikon screws and it does a great job of removing them cleanly.

Speaking of thread glue (screws and rings) ,I've some trouble in loosening ML 50mm 1.4 I can see red glue ,but acetone not working. Is it any other thing better for Nikon threaded ?

Acetone will not work on red loctite. You will definitely need heat to get it to release..
I've never seen red loctite factory applied to any nikkor lens, but I haven't seen them all.
Nikon used an epoxy that was grayish white in color.
Some variants of nikon epoxy will not release under heat and require acetone. Shocked Rolling Eyes

You will enjoy those. They're both great.

Nikon sure used to be good at 105mm.

I am not sure it is 100% true there may be Gauss Chrome nose and Black Sonnar's, but those would be exceptions to the rule (and if so rare, may have collectors value Wink ). Any chrome nose in the 1xxxx and 2xxxx range should be sonnar though. The rear element will always tell you.

Pentax was the only other top brand manufacturer that did 105's it seems. I guess the other's made 100mm's (Minolta, Canon, Konica, Olympus)

The 105mm f/1.8 Nikkor is great fun, but if you want the real gem, try the 105mm f/2 DC Nikkor.

Unfortunately, there are no hard and fast "cast in stone" rules when it comes to Nikkor lens serial numbers of this era.
This was at a time when nothing usable was discarded or recycled, which makes good economic sense, and sometimes creates a bit of confusion in manufacturing history.

As for the bayonet screws, they are so easily changed out, it could be anything...
I've seen enough variations in the nikkor lens line after almost a life time of use to relax with manufacturing history more than a bit.
Roland's pages are a very good reference point, and aid in understanding manufacturing periods, with the understanding that there is always the potential for things to overlap a bit.

Indeed, I have seen the same with Minolta lenses. There are "transition" samples where clearly old stock surplus components had been used in early samples of a new lens update, especially internal component. Typical transition components are srcews (e.g. switching from slotted brass to steel cross-head), switch-over from brass to aluminium spacers and/or retaining rings, switching from aluminium to plastic name-rings, etc.

Whilst some of the surplus stock of components would likely have been held back for their repair service, it would make sense to use the remainder as appropriate.

Flat screws but AI converted and different aperture ring. Mine is knurled. Yours has a diamond pattern. My aperture fork has flat screws yours (AI) has JIS screws. Paid the equivalent of $35 in Yen from Yahoo.jp ($29 for the gauss)
