Sorry, my German engineering/projectmanagement background had kicked in. Did not want to
cause confusion ...

Thank you, Michael, for the confirmation.

No worries, Klaus!

Thank you so much for this reference. There is information about many lenses I drool over and a few I never heard of.

An observation regarding the 55/3.5 Micro-Nikkor-P. It's a few notes not a correction or any such. This was my first "real lens" back in 1970. I bought it with a Nikkormat FTn.

The 55/3.5 Micro-Nikkor-P was designed with 1:1 in mind though the lens did not achieve that alone. It was sold with the matched 27.5mm Nikon M2 tube. The M2 provided auto aperture but had no meter linkage so a con would be the lens and tube had to be used with stop-down metering.

In some ways I consider a lens like the 55/3.5 Micro-Nikkor-P's lack of 1:1 in itself an advantage. There is no loss of focal length when focusing to 1:1 or like the AF 70-180/4.5-5.6D ED Micro-Nikkor at 1:0.75. The AF 70-180/4.5-5.6D ED is a real 180mm lens at infinity but more like a versatile 105mm at 0.75x.

The M2 tubes are probably mostly separated from their original lenses and the lenses are sold without though they were paired in the box when originally sold. Later, I'm not sure when there was a 27.5mm PK-3 tube that I think was sold separately. Maybe the PK-3 tube was designed for the K-type 55/3.5 Micro-Nikkor. When I bought a 55/3.5 AI Micro-Nikkor the PK-13 tube was sold separately.

I loved the 55/3.5 though it was slow for an only lens. My previous camera were all Kodak "box" cameras like the Kodak Instamatic 100 that didn't focus at all and was only good to about 1.5m (5') which was very restrictive for me. I started two Nikon systems: one in 1970 and then another in 1978. I sold out of Nikon just before Nikon started advertising multi-coated lenses probably in the summer of 1976. I stared my new Nikon system with a Nikon F2As and a 55/3.5 AI Micro-Nikkor. My first AF lens was an AF 60/2.8 Micro-Nikkor.

That's my 2 cents on the 55mm f3.5 Micro-Nikkor-P

I'm sure you don't need to read it since a lot of the information I learned from you. LOL.

[Bjørn Rørslett]

It's seen through your eyes. Always a potential of seeing something in new light as it were.

Michael, thank you for the energetic update!  Downloaded the v.5.0 for further references!

Here's a remark for your next v.6 update, just in case you plan to have a version 6...

I noticed that most of the data for Apo-Lanthar 90mm f:3.5 are from the 125 f:2.5 Apo-Lanthar instead:


Voigtlander 90mm f/3.5 SL-II APO-Lanthar
Focal Length: 125mm Widest Aperture: f/2.5 Narrowest Aperture: 22
Aperture Blades: 9 Filter Size: 58mm
Hood: Include, small hood.
Close Focus Distance: 19.68 inches (50 centimeters), 12.6 inches (32 centimeters)
Reproduction Ratio: 1:3.5/1:1.8
Focus Throw: 270º
Weight: 11.29 ounces (320 grams)


What's marked in red is for the 125mm

Should read:
Voigtlaender 90mm f/3.5 SL-II APO-Lanthar
Focal Length: 90mm Widest Aperture: f/3.5 Narrowest Aperture: 22
Aperture Blades: 9 Filter Size: 52mm / 39 mm (on small hood)
Hood: Include, small hood.
Close Focus Distance: 19.68 inches (50 centimeters), 12.6 inches (32 centimeters) with close-up lens (included, 39 mm)
Reproduction Ratio: 1:3.5/1:1.8
Focus Throw: 260º
Weight: 11.29 ounces (320 grams)

The errors have been carried over from version 4. Not a big deal, but worthy noticing...

Ciao from Massimo
