You show some really rare stuff here. Tood bad I cannot read Chinese..[/quote]

Here is an image of a Dongfeng 120 SLR, a copy of Hassyblad 500C but with a top speed of 1/1000! Only a few dozen such cameras, and even fewer accessary lenses were made. They are not mine. I may have to sell a kidney and an arm for them these days. Wink

I heard that , to attain the 1/1000s top speed, they used a special alloy main spring for the build-in shutter of those lenses.

Another version of that Shanghai made reduction lens. The previous user told me it is a 1/20x reduction lens. This one was made in 1979.

Here is a Zeiss lens with a Japanese focusing tube. I know German Zeiss company has Japanese partners for their lenses, but never heard of this one before.

Only three known to exist (I had two), from the Russian Mission to Mars.

Some of my collection is rather "far flung".

I own a small share in the truly unique lens shown here mounted on custom camera and special tripod:

An extremely rare Chinese lens went away a moment ago when I was bragging my collection here. Rolling Eyes

A X-ray lens perhaps? This fast F0.82 65mm lens was made in 1984. I never saw it before. It was made by the same factory that made those cine optics.

Please remind me to brag about this glorious Yuropean* 34500mm f/0.88 when ESO is done building it (first light expected by 2024).

Beijing Nr.608 factory made some fine movie lenses. The factory was assisted in the early days by Carl Zeiss Jena of East Germany. One of the zoom lenses cost 35,000 yuan RMB according to the company's price list that was still seen a few years ago. Those projection lenses are much cheaper for a couple of hundred yuan a piece only.

I own a few of the primes of this factory, and some by another well known factory. These are never used. Smile

Never ending list of early rare Chinese lenses. This is not mine. A 45mm F1.5 industrial video lens with a resolving power of 600 lp/mm! These must be well kept secrets before. The lens was made in 1976. Those high quality lenses were usually packed in a wooden box. My 16mm F1.6 lens should also have a high resolving power. I heard that some Chinese enlarging lenses are also very good. I will show you some later.

I own a few of these rarely seen anamorphic projection lenses. These two were made by another factory. These were made in 1974. Some guys converted them to photographic lenses and took nice pictures of very wide angle.

Our own teacher Mr.Klaus told me many years ago that the UV 60/4 is a rare lens. But I forgot exactly how many pieces were made. However, you hardly saw them offered for sale even in a year's period of time.

The 28mm F1.7 1/10x beside it is another high quality lens for computer chip-making made by the same Fujian factory in 1979. It has a solid quality feel, and is the only lens with 'People's Republic Of China' engraved on the front ring. A fellow collector told me that it has a resolving power of 650lp/mm.

A couple of uncommon, or even rare Carl Zeiss Jena products. The Mikrotar 45/4.5 is a high quality macro lens that even covers medium format. Although it is a 3g/3e simple lens, it makes very sharp images.
The 2x converter is a rare one, that even some knowleadgeable microcope experts were not aware of them. It converts a RMS objective to a M19 one, so a common RMS objective could be used on a special M19 mount microsscope.

I saw an on-line image of an American version of the missle tracking lens. The happy owner told us it is a 2000mm F8 lens, and it looks about the same size and weight, and even the same design and colour as my Chinese one. These obsolete militray lenses are more often seen in the United States. Unlike me, it looks like he actually used it. Like 1 small
