Nikkor-P 105mm f2.5 (Turbo fungus)


Decent lens, especially for the close focus stuff. I've had 2 of them.
Very good portrait lens if you can get it clean enough.

I thought I had that lens, but I haven't - ithe lens I have is a Haiou 64 50 / 2 which is a Chinese lens made by Seagull that was either a copy of the Minolta or made under licence from Minolta, so now I'm wondering if the Haiou is a copy of the Minolta - or - a copy of the Russian Helios 44M, which is what I suspected?

Can you post pictures of the lens please, I'm intrigued Question Here's the Haiou, a solid lump of glass and brass.


The Seagull lens is more likely copied directly from the original Biotar. By the mid to late 60s when they released it, China and the USSR were in the middle of a wee diplomatic disagreement, and much of the industrial co-operation seen prior to that was discontinued. This can be seen in the design of the Seagull SLR camera, based more on Japanese tech than Soviet, although there are many signs also pointing away from the idea of mere slavish copying popular in the western imagination.

I have seen information on a Chinese website (which I can't locate now) indicating that one of the elements for the Haiou lens used 'special' glass which was obtained from Germany. In the same post it went on to say that the similar lens for the Pearl River SLR had two elements using 'special' glass from the same source country, indicating the presence of at least two different Chinese re-calculations of the same base scheme.

Here are the glasses found on reference books for the Chinese 58/2.0s. I am not sure if the info is 100% correct but it is a good starting point to know more...

The Minolta acquired by pepperberry is the Minolta MC 1:1.2 f=58mm:

It's much (much!) faster than your Chinese 58mm which is 1:2 only, and therefore a completely different lens.

The 2/58mm Haido may or may not be a copy of the Biotar 2/58 mm - I simply don't know ...

I'm always interested in good value 500s which are also good performers.
Which of your lenses was the best value, in terms of image quality?

If we're talking about vintage manual focus lenses, it certainly would be the Canon nFD 4.5/500mm L.
One fluorite and one ULD lens, and impeccable performance.

Mine wasn't a 500 it was a 1000mm Nikon f11 mirror.
Remarkable image quality. Definitely not one to cart about all day though.

Here's an example from Silverstone shot from the back of the stands.
